Chapter 1 Using the SDMS Software This chapter describes the LSI Logic Storage Device Management System (SDMSTM) software, and includes these topics: * * * * Section 1.1, "Introduction," page 1-1 Section 1.2, "Overview," page 1-2 Section 1.3, "SDMS Device Drivers," page 1-4 Section 1.4, "Basic Guidelines," page 1-4 1.1 Introduction The LSI Logic PCI SDMS is a complete software package that solves the increasingly complex problem of managing system I/O. It seamlessly addresses hardware and software interfaces by supporting the LSI Logic family of SCSI processors and controllers, and a wide range of SCSI peripheral devices. At the same time, it offers interoperability across application programs, operating systems, and host platforms. SDMS 4.0 software provides a standard method to interface SCSI I/O subsystems with devices, operating systems, and application software. It also enhances system capabilities already provided by SCSI controllers and processors by facilitating system-wide SCSI device access.

Figure 1.1 . The LSI Logic SDMS Software Operating System Supports SDMS Storage Device Driver SDMS Storage BIOS Supports LSI Logic Controller or Processor 1.2 Overview An LSI Logic SCSI controller or processor can control peripherals such as hard disk drives, CD-ROM drives, tape drives, scanners, and removable media. You can connect up to 15 wide (16-bit) SCSI peripheral devices or seven 8-bit SCSI peripheral devices (by using the SCSI bus) to a SCSI host adapter on which the SCSI controller or processor resides. 1-2 Using the SDMS Software Copyright (c) 1993-2001 by LSI Logic Corporation.

All rights reserved. 1-3 1.3 SDMS Device Drivers The SDMS device drivers translate an operating system I/O request into a SCSI request. Each SDMS SCSI device driver is operating system specific and is designed to work on standard LSI Logic chip implementations. Currently, LSI Logic provides PCI to SCSI device drivers for the following operating systems: * * * * * * * * * * MS-DOS 6.0/Windows 3.1X Windows 95, Windows 98, and Windows Me (Millennium Edition) Windows NT - 4.0 Windows 2000 OS/2 - 4.XX SCO OpenServer - Release 5.XX UnixWare - 7 Solaris - 7 and 8 Linux NetWare - 4.XX and 5.XX (NWPA) This user's guide provides device driver installation and configuration instructions for each of these operating systems. 1.4 Basic Guidelines Some basic rules for using SDMS software and installing a SCSI host adapter device follow. The SDMS software requires an IBM PC/AT or compatible computer with an 80486 or higher microprocessor. An understanding of basic operating system commands is assumed. In addition, users of this manual should have a general knowledge of the SCSI standard. Before using the SDMS software, you should configure the SCSI controller into your system, taking into account the configuration of other host adapters and system resources. 1-4 Using the SDMS Software Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. LSI Logic recommends that you back up all data before making any changes or installing any software, including LSI Logic SCSI controllers and software. Failure to adhere to this accepted computer practice may lead to loss of data. You must terminate both ends of the SCSI bus. Refer to the hardware manuals for the devices and users' guides for the host adapters to properly terminate the bus. Also you should locate where jumpers or dip switches are for setting SCSI ID numbers. Usually, the host adapter is ID 7. The devices are then set at IDs 0 through 6 (plus 8 through 15 for Wide SCSI). The bootable hard drive must have the lowest numerical SCSI ID, unless you are able to use the BIOS Boot Specification (BBS). Refer to Chapter 2 for additional information regarding the BBS. The red or blue line on a standard SCSI cable (or the black line on one end of a multicolored SCSI cable) designates pin 1 on the cable connector and must connect to pin 1 on the device and host adapter connector. Refer to the hardware manuals for the devices and the controller to locate pin 1 of the connector. If the system already has an internal bootable hard drive (IDE, ESDI, or ST506), the drivers for the SCSI device(s) must reside on the internal bootable drive.

Chapter 2 SCSI BIOS and Configuration Utility This chapter describes the SDMS SCSI BIOS and Configuration Utility. It includes these topics: * * * * * Section 2.1, "Introduction," page 2-1 Section 2.2, "Boot Initialization with BBS," page 2-3 Section 2.3, "Using the SCSI BIOS Configuration Utility," page 2-3 Section 2.4, "Starting the SCSI BIOS Configuration Utility," page 2-4 Section 2.5, "Exiting the SCSI BIOS Configuration Utility," page 2-22 2.1 Introduction The SDMS SCSI BIOS is the bootable ROM code that manages SCSI hardware resources. It is specific to a family of LSI Logic SCSI controllers or processors. The SDMS SCSI BIOS integrates with a standard system BIOS, extending the standard disk service routine provided through INT13h. During the boot time initialization, the SCSI BIOS determines if there are other hard disks, such as an IDE drive, already installed by the system BIOS. If there are, the SCSI BIOS maps any SCSI drives it finds behind the drive(s) already installed. Otherwise, the SCSI BIOS installs drives starting with the system boot drive. In this case, the system boots from a drive controlled by the SCSI BIOS. For version 4.05.00 and higher, LSI Logic supports the BIOS Boot Specification (BBS). The next section, "Boot Initialization with BBS," discusses selecting boot and drive order.

The SDMS SCSI BIOS supports the following devices and their associated LSI Logic host adapters: * * * * * * * * * * * * LSI53C810, LSI53C810A, LSI53C810AE (LSI8100S, LSI8100ASP, LSI20810) LSI53C815 (LSI815XS, LSI8150SP) LSI53C825, LSI53C825A (LSI8250S, LSI8251S, LSI8251D, LSI8250ASP, LSI8251ASP, LSI8251AD) LSI53C860, LSI53C860AE (LSI8600SP, LSI20860) LSI53C875, LSI53C875E (LSI8750SP, LSI8751SP, LSI8751SPE, LSI8751D) LSI53C876 (LSI22801, LSI22802) LSI53C885 LSI53C895 (LSI8951U, LSI8952U) LSI53C895A (LSI8953U) LSI53C896 (LSI22910, LSI21002, LSI22902) LSI53C1000 (LSI20160, LSI20160L) LSI53C1010 (ITI6200U3LP, LSI22915A, LSI21040, LSI22903, LSI21003) 2-2 SCSI BIOS and Configuration Utility Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 2.2 Boot Initialization with BBS The SDMS SCSI BIOS provides support for the BBS, which allows you to choose which device to boot from by selecting the priority. To use this feature, the system BIOS must also be compatible with the BBS. If your system supports the BBS, then use the system BIOS setup menu to select the boot and drive order. In the system BIOS setup, the Boot Connection Devices menu appears with a list of available boot options. Use that menu to select the device and rearrange the order. Then exit saving changes to continue the boot process. 2.2.1 CD-ROM Boot Initialization The SCSI BIOS supports boot initialization from a CD-ROM drive. The five types of emulation are: * * * * * No emulation disk Floppy 1.2 Mbyte emulation disk Floppy 1.44 Mbyte emulation disk Floppy 2.88 Mbyte emulation disk Hard disk emulation The type of emulation determines the drive letter assignment for the CD-ROM. For example, if you load a 1.44 Mbyte floppy emulation CD-ROM, then the CD-ROM drive would become the designated A: drive, and the existing floppy would become drive B:. 2.3 Using the SCSI BIOS Configuration Utility This section provides the menu formats and user inputs available to inform all users about this utility prior to running it. All SCSI BIOS Configuration Utility screens that display various menus are partitioned into fixed areas. This area provides static general help text information.

You may decide to alter these default values if 2-4 SCSI BIOS and Configuration Utility Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. there is a conflict between device settings or if you need to optimize system performance. You can see the version number of your SCSI BIOS in a banner displayed on your computer monitor during boot. If the utility is available, the following message also appears on your monitor: Press Ctrl-C to start LSI Logic Configuration Utility... This message remains on your screen for about five seconds, giving you time to start the utility. If you decide to press Ctrl-C, the message changes to: Please wait invoking LSI Logic Configuration Utility... After a brief pause, your computer monitor displays the Main menu of the SCSI BIOS Configuration Utility. The following messages may appear during the boot process: * Adapter removed from boot order, parameters will be updated accordingly! appears when an adapter is removed from the system or relocated behind a PCI bridge. Configuration data invalid, saving default configuration! appears if none of the information in NonVolatile Random Access Memory (NVRAM) is valid. Found SCSI Controller not in following Boot Order List, to Add: Press Ctrl-C to start LSI Logic Configuration Utility... or Adapter configuration may have changed, reconfiguration is suggested! could appear when fewer than four adapters are in the boot order and adapters exist in the system which are not in the boot order. * * The SDMS SCSI BIOS does not control all devices detected by this configuration utility. Devices such as tape drives and scanners require that a device driver specific to that peripheral be loaded. To make changes with this menu-driven utility, one or more LSI Logic SCSI host adapters must have NVRAM to store the changes. You can change four sets of configurations. You make changes on subordinate menus called from the Main menu, which is opened when you start the SCSI BIOS Configuration Utility. The subordinate menus are: Starting the SCSI BIOS Configuration Utility Copyright (c) 1993-2001 by LSI Logic Corporation.

Indicates whether SCSI parity is enabled for an adapter. When disabled, you must disable disconnects for all devices, as parity checking for the reselection phase is not disabled. If a nonparity generating device disconnects, its operation will never complete because the reselection fails due to parity error. Indicates the SCSI identifier of an adapter. LSI Logic recommends that this field be set to the highest priority SCSI identifier, which is 7. Indicates the order in which to scan SCSI identifiers on an adapter. Changing this item will affect drive letter assignment(s) if more than one device is attached to an adapter. Specifies the removable media support option for an adapter. Removable media support only applies to devices that report themselves as a hard drive. It does not apply to CD-ROM devices or Magnetic Optical devices. None indicates no removable media support whether the drive is selected as first (BBS), or is first in the scan order (non-BBS). Boot Drive Only provides removable media support for a removable hard drive if it is first in the scan order. With Media Installed provides removable media support regardless of the drive number assignment. You must have media in the drive at bootup.

Field Type [Value] Configuration [SCSI Plug and Play Mapping/ Alternate CHS Mapping] Descriptions Defines how the Cylinder Head Sector (CHS) values are mapped onto a disk without pre-existing partition information. SCSI Plug and Play Mapping automatically determines the most efficient and compatible mapping. Alternate CHS Mapping utilizes an alternate, possibly less efficient mapping that may be required if a device is moved between adapters from different vendors. Caution: Neither of these options has any effect after a disk has been partitioned using the FDISK command. The FDISK utility is a tool that you can use to delete partition entries, one or all of them. If all partition entries are deleted, it is necessary to reboot to clear memory or the old partitioning data will be reused, thus nullifying the previous operation. Use care to ensure that the correct disk is the target of an FDISK command. CHS Mapping Spinup Delay (secs) Configuration [1 to 15] Indicates the delay in seconds between spinups of devices attached to an adapter. Staggered spinups balance the total electrical current load on the system during boot. The default value is 2 seconds. Indicates whether an adapter has one or more devices attached that are shared with one or more other adapters. Therefore, the SDMS SCSI BIOS should avoid SCSI bus resets as much as possible. This option allows you to enable an adapter to join a cluster of adapters without doing any SCSI bus resets. This is a requirement for the Microsoft Cluster Server. The default value is No with an alternate option of Yes. Secondary Configuration Cluster Server [Yes/No] Termination Control Configuration [Auto/Off] If available, the field Indicates whether an adapter has automatic termination control. If not available, its current status is either Auto or Off. Auto means that the adapter automatically can determine whether it should enable or disable its termination. Off means termination on the adapter is off and the devices at the ends of the SCSI bus must terminate the bus. Restore Defaults Executable Press Enter to obtain default settings.

Indicates the ASCII device identifier string, as extracted from the device's inquiry data. Indicates the maximum synchronous data transfer rate of the adapter in megabytes per second corresponding to the width and transfer rate settings that follow. Indicates the maximum synchronous data transfer rate of the adapter in megatransfers per second. Can be changed to a lower transfer rate. Displays the maximum data width of the adapter in bits. Can be changed to narrower, if available. Indicates whether to scan for this SCSI identifier at boot time. Utilizing this setting allows you to ignore a device. This decreases boot time by disabling inquiry of unused SCSI identifiers. Set this option to No if there is a device that you do not want to be available to the system. Also, on a bus with only a few devices attached, you can speed up boot time by changing this setting to No for all unused SCSI IDs. MT/Sec Data Width Scan ID Scan LUNs > 0 Configuration [Yes/No] Indicates whether to scan for Logical Unit Numbers (LUNs) greater than zero for a device. LUN 0 is always queried. Use this option if a multi-LUN device responds to unoccupied LUNs or if it is desired to reduce the visibility of a multi-LUN device to LUN 0 only. Set this option to No if you have problems with a device that responds to all LUNs whether they are occupied or not. Also, if a SCSI device with multiple LUNs exists on your system but you do not want all of those LUNs to be available to the system, then set this option to No. This will limit the scan to LUN 0. Disconnect Configuration [On/Off] Indicates whether to allow a device to disconnect during SCSI operations. Some (usually newer) devices run faster with disconnect enabled, while some (usually older) devices run faster with disconnect disabled.

Field Type [Value] Executable [0-9999] Description SCSI Timeout Indicates the maximum allowable time for completion of a SCSI operation in seconds. Since timeouts provide a safeguard that allows the system to recover should an operation fail, LSI Logic recommends that a value greater than zero be used. A value of zero allows unlimited time for an operation to complete and could result in the system hanging (waiting forever) should an operation fail. Note: This field is executable and must be selected with the Enter key. You also input the new value with the number keys from either the keyboard or number pad. Queue Tags Configuration [On/Off] Configuration [Yes/No] Indicates whether to allow the use of queue tags for a device. Currently the BIOS does not use queue tags. This item specifies queue tag control to higher level device drivers. Indicates whether this device can be selected as the boot device. This option is only applicable to devices attached to adapter number zero in the boot list on non-BBS systems. It provides primitive BBS flexibility to non-BBS systems. Allows low-level formatting on a disk drive, if enabled. Low-level formatting will completely and irreversibly erase all data on the drive. To low level format a device, select the device from the menu and use the arrow keys to move the cursor to the Format column. Press Enter. Note: Formatting will default the drive to a 512-byte sector size even if the drive had previously been formatted to another sector size.

This option allows the ability to prevent a hook on INT40h, if required. The two settings are: Hook Interrupt, the default, and Bypass Interrupt Hook. Hook Interrupt is the normal operation that supports booting CD-ROMs in floppy emulation mode on most machines. On certain platforms, the system BIOS uses the INT40h interrupt chain in a nonstandard way. On these platforms, you should use the "Bypass Interrupt Hook" setting. This setting prevents a hook into the INT40h chain. If the "Bypass Interrupt Hook" setting is used on systems that do not require it, the CD-ROM may fail to boot and an error message may appear and indicate it is unable to read the boot device. Note:Try toggling this value if your machine fails to boot a CD-ROM in floppy emulation mode. Support Interrupt Restore Defaults Executable Press Enter to obtain default settings.

These drivers allow connection of SCSI devices including disk drives, CD-ROMs, and tape drives for PCI-based machines. To support a new SCSI device, Windows 95/98/Me architecture requires that a class driver for that type of device be present. These are usually supplied by Microsoft, or possibly by the peripheral manufacturer. No changes to SYMC8XX.MPD, SYM_HI.MPD, or SYM_U3.MPD are required. These drivers are only supported under Windows 95/98/Me. Introduction Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 3-3 A Windows application passes SCSI commands directly to the SCSI devices by using the SCSI pass-through facility. Refer to Microsoft Windows 95/98/Me documentation for more details. This facility allows applications to directly control and access SCSI devices by filling in a data structure and calling into the port driver. The SYMC8XX.MPD and SYM_HI.MPD drivers support Ultra SCSI protocol, providing twice the raw data transfer rate of Fast SCSI for disk drives and LSI Logic host adapters that support Ultra SCSI. These drivers also support Ultra2 SCSI protocol, providing quadruple the raw data transfer rate of Fast SCSI. The SYM_U3.MPD driver supports Ultra160 SCSI protocol providing up to 160 Mbytes/s data transfer for double transition. Ultra160 also includes CRC, PPR, and Domain Validation. The standard Ultra160 SCSI protocol performs 80 megatransfers per second resulting in approximately double the synchronous data transfer rates of Ultra2 SCSI. Caution: Ultra SCSI requires more stringent SCSI bus cabling setups than Fast SCSI. Ultra2 SCSI and Ultra160 SCSI require Low Voltage Differential (LVD) termination. 3.2 Using the SYMC8XX/SYM_HI/SYM_U3 Drivers The SDMS Software Device Driver and Utilities CD-ROM contains the SYMC8XX.MPD, SYM_HI.MPD, and SYM_U3.MPD drivers and their associated files in this directory: {CD-ROM Drive Letter}:\DRIVERS\WIN9X You must prepare an SDMS Driver Diskette before proceeding with the installation instructions. 3.2.1 Preparing an SDMS Driver Diskette Copy the files listed in this section to the root directory of a clean diskette.

All rights reserved. the system is not performing optimally and methods to correct the problem. If you do not encounter any problems, the new driver is operating properly. Otherwise, consult Section 3.4, "Troubleshooting," for additional information. 3.4 Troubleshooting Some potential problems and their suggested solutions are: During installation, no SCSI devices are found. * * * * Ensure that all devices are powered on and terminated correctly. Check that no devices have duplicate SCSI IDs. Make sure INTA is assigned for the PCI slot(s) where your SCSI host adapter(s) are installed. Be sure that all devices appear properly in the display banner of the SDMS SCSI BIOS at boot time. Problems with Ultra SCSI devices using Ultra SCSI protocol. If the system is configured with an LSI Logic host adapter that supports Ultra SCSI, an Ultra SCSI device is on the SCSI bus, and Ultra SCSI support by the SYMC8XX.MPD, SYM_HI.MPD, or SYM_U3.MPD driver is enabled, intermittent problems and possible system crashes can occur. It may be that the SCSI bus cable and terminators do not conform to the Ultra SCSI specification. To resolve problems with Ultra SCSI devices, follow these steps: Step 1. Disable Ultra SCSI support using the procedure described in Section 3.5.1, "Enabling/Disabling Ultra SCSI Support," page 3-15 if the system is bootable. or Hold down the F8 function key when Starting Windows 95/98/Me... appears if the system is not bootable to Windows 95/98/Me. Step 2. Select Safe Mode. Troubleshooting Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 3-13 Step 3. Disable Ultra SCSI support using the procedure described Section 3.5.1, "Enabling/Disabling Ultra SCSI Support," once the system is booted. If the system operates properly without Ultra SCSI enabled, it is highly likely that the SCSI bus cable and terminators are not configured correctly for Ultra SCSI. Refer to the LSI Logic host adapter user's guide for information on Ultra SCSI cabling requirements. Step 4. Verify that the devices appear with the proper value for speed in the SDMS SCSI BIOS banner at boot time. Refer to Chapter 2, "SCSI BIOS and Configuration Utility," for additional details. Problems with scanners. If a scanner is not operating properly (either the scanner is not found or a SCSI interface error occurs during scanning), it is possible that the third party scanner drivers do not support the auto request sense feature of LSI Logic host adapters. Disable the auto request sense feature as described in Section 3.5.2, "Disabling Auto Request Sense Support," and try the scanner operation again. The system hangs at boot, has a long boot time, or SCSI device not available. Some older SCSI devices do not tolerate Domain Validation operations. At system boot time, Domain Validation is performed to test the data integrity of the SCSI bus between the host adapter and each target device. With some older SCSI devices, these operations can cause the device to stop responding to SCSI commands. Refer to the Command Line Options Section 3.5.4, "Disabling Domain Validation Support," page 3-17. Disable this support as described either for a specific problem SCSI target or all adapters controlled by the SYMC8XX.MPD, SYM_HI.MPD, or SYM_U3.MPD driver. 3.5 Using the Command Line Options This section describes various command line options that allow changes to the host adapter. 3-14 Windows 95, Windows 98, Windows Me Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 3.5.1 Enabling/Disabling Ultra SCSI Support Settings in the adapter NVRAM control Ultra SCSI support. These settings can be viewed or changed through the SCSI BIOS Configuration Utility. During system boot, after the LSI Logic PCI SCSI BIOS banner, the message Press Ctrl-C to start Configuration Utility appears for a few seconds. To enable/disable Ultra SCSI support, follow these steps: Step 1. Press Ctrl-C to start this utility. Step 2. Select one of the adapters displayed, then select Device Properties. This shows the Sync Rate for each device and the selected adapter. Step 3. Set the speed to 20 Mbytes/s for an Ultra device (for width of 8) or 40 Mbytes/s (for width of 16). or Set the speed to 10 Mbytes/s (for width of 8) or 20 Mbytes/s (for width of 16) to disable Ultra. If the speed of the adapter itself is changed, the speed for all devices will be set no higher than the adapter speed. 3.5.2 Disabling Auto Request Sense Support When the system installs the SYMC8XX.MPD, SYM_HI.MPD, and/or SYM_U3.MPD drivers, support for auto request sense is enabled. Auto request sense is a feature of the adapter where certain device information is obtained automatically without system control, thereby increasing overall performance. However, some third party peripheral drivers do not support the use of auto request sense, resulting in perceived device failures. To allow these devices to operate properly, the auto request sense feature can be disabled using the Device Manager on a per adapter basis. Follow this procedure to disable auto request sense support: Step 1. Click on the Start button. Select Settings-->Control Panel. Step 2. Double click on the System icon. Using the Command Line Options Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 3-15 Step 3. Click on the Device Manager tab. Step 4.

Select the desired adapter, and click on the Properties button. Step 6. Click on the Settings tab. Step 7. Type DisableAutoReqSense=1;. If there is already an entry displayed, type the above at the end of the existing entry. Be sure to include the semicolon. Step 8. Click OK to exit the Settings tab. Step 9. Click OK again. If the entry was changed, the System Settings Change dialog box appears. Step 10. Click Yes to restart the computer. After the system reboots, auto request sense is disabled for the selected adapter. To re-enable auto request sense, delete the entry that was made above. If other entries exist, be sure to leave them intact. 3.5.3 Enabling SCAM Support SCAM is a protocol that allows SCAM-compliant peripherals to assign their SCSI IDs dynamically at boot time, eliminating the need for you to check and set unique SCSI IDs. The SDMS PCI BIOS and the SYMC8XX.MPD, SYM_HI.MPD, and SYM_U3.MPD drivers have this feature disabled by default. Some peripherals have problems with the SCAM protocol, resulting in the device either not being seen by the operating system, or not working correctly. Windows 98 and Windows Me do not support the use of SCAM. If you desire usage of the SCAM protocol, follow these steps to enable SCAM Step 1. Click on the Start button. Select Settings-->Control Panel. Step 2. Double click on the System icon. 3-16 Windows 95, Windows 98, Windows Me Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation.

After the system reboots, SCAM is enabled for the selected adapter. To disable SCAM, delete the entry that was made above. If other entries exist, be sure to leave them intact. 3.5.4 Disabling Domain Validation Support When the SYMC8XX.MPD, SYM_HI.MPD, or SYM_U3.MPD driver is installed, support for Domain Validation is enabled. Domain Validation is a feature of the adapter where the data transfer speed between the adapter and each target is tested at system boot. If the test fails, the data transfer speed is reduced and the test is repeated until a supported data transfer speed is found. However, some older SCSI devices do not properly support the standard SCSI commands used during this testing, resulting in the system not booting or a device not available. To allow these devices to operate properly, you can disable the Domain Validation feature by using the Device Manager for all adapters controlled by the respective driver, or by using the SCSI BIOS Configuration Utility on a per device basis. Using the Command Line Options Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 3-17 To disable Domain Validation support for all adapters controlled by the SYMC8XX.MPD, SYM_HI.MPD, or SYM_U3.MPD driver, follow these steps: Step 1. Click on the Start button. Select Settings-->Control Panel. Step 2. Double click on the System icon. Step 3. Click on the Device Manager tab. Step 4.

If the entry was changed, the "System Settings Change" dialog box appears. Step 10. Click Yes to restart the computer. After the system reboots, Domain Validation is disabled for adapters controlled by the selected driver. To re-enable Domain Validation, delete the entry that was made above. If other entries exist, be sure to leave them intact. To disable Domain Validation support for a selected device, using the SCSI BIOS Configuration Utility, follow these steps: Step 1. Press Ctrl-C to start this utility when prompted to do so during system boot. Step 2. Select the desired adapter and press Enter. Step 3. Choose "Device Selections" and press Enter. 3-18 Windows 95, Windows 98, Windows Me Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. This shows the Sync Rate and Width for each device and the selected adapter. Step 4. Set the Sync Rate to 0 and Width to 0 for the selected device. This sets the device to asynchronous/narrow transfers and Domain Validation functions are not issued to this device. Step 5. Exit the SCSI BIOS Configuration Utility and save changes. 3.5.5 Multiple LSI Logic Host Adapters Considerations If multiple LSI Logic PCI SCSI host adapters are installed in the system, special actions are sometimes required to install or change drivers. This is due to the fact that the bundled driver supports some LSI Logic host adapters, and also that one SDMS device driver can support multiple LSI Logic host adapters installed in the system. With multiple LSI Logic adapters, it is possible to have a situation where one adapter is assigned to one driver, and another is assigned to a different version of the same driver. This can cause conflicts that may cause the system to switch to real-mode drivers, affecting performance and access to CD-ROM or tape drives. When installing additional boards or updating drivers, only one version of the appropriate driver controls all the LSI Logic host adapters. To update your system to the correct driver, two methods are available. 3.5.5.1 Method 1 Follow these steps: Step 1. Change the driver for a particular host adapter to the desired driver by using the Device Manager. Step 2. Click No when prompted to reboot the system for the new settings to take effect. Step 3. Change drivers for all LSI Logic host adapters in the system supported by that same driver to the new driver, and reply No to rebooting until the final adapter is changed. If booting from a SCSI device, ensure that the adapter controlling this device is the last one changed. Using the Command Line Options Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 3-19 3.5.5.2 Method 2 Follow these steps: Step 1. Determine which driver file is active for all adapters through the Properties tab in Device Manager. Go to the: \WINDOWS\SYSTEM\IOSUBSYS directory and rename the driver file to an extension other than MPD. Step 2. Reboot the system. While booting, the system may ask to load the bundled driver file from the Windows 95/98 installation disk. Step 3. Click OK. Step 4. Click Skip File when the system says it cannot find the file. Repeat this step for all adapter messages while booting. Step 5. Use the Device Manager to change the driver for each adapter to the desired driver after the system is booted. Step 6. Do not reply Yes to reboot the system until the final adapter has been changed. 3.6 Using SCSI Tools for Windows 95/98 SDMS SCSI Tools software for Windows 95/98 is a support utility that provides a mechanism for examining host adapters and SCSI devices within the Windows 95/98 environment. Under Windows 95/98, the ASPI support is bundled with the operating system. 3.6.1 Features The SCSI Tools for Windows 95/98 support these features: * * * Examination of SCSI device parameters Power management support Disk cache management support 3-20 Windows 95, Windows 98, Windows Me Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation.

It provides a graphical user interface environment that incorporates many high-level features. Refer to the Microsoft Windows NT documentation for more information. An I/O manager handles I/O requests in Windows NT by going through the appropriate drivers to address a SCSI peripheral. Windows NT provides class drivers for hard disk, floptical, CD-ROM, printer, and scanner peripherals. Other class drivers, provided by peripheral manufacturers, may be added to support new devices. Tape device support is built into the operating system itself and does not PCI Storage Device Management System SDMS 4.0 User's Guide Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 4-1 require a class driver. Microsoft provides the port driver and LSI Logic provides the miniport drivers, which are called SYMC8XX.SYS, SYM_HI.SYS, and SYM_U3.SYS. These drivers complete the path to an LSI Logic controller or processor with an optional SDMS SCSI BIOS. LSI Logic uses the same filenames for their drivers for different Windows operating systems. The driver files are packaged either in separate subdirectories based on the Windows operating system or on different flex disks. To determine the driver file for Windows NT 4.0, note that the filename ends with .SYS. To determine the operating system version, go into Windows Explorer, display the driver file, right click on the filename, click on Properties, and click on the Version tab. Finally, click on the Internal Filename in the lower section. For Windows NT 4.0, the filename appears as filename (NT 4.0). For example, SYMC8XX.SYS (NT 4.0). The sections below describe these drivers and their installations. 4-2 Windows NT 4.0 Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved.

They have transitioned from a SYM prefix to an LSI prefix. No name changes have occurred for the SDMS Windows NT 4.0 miniport drivers. The SYMC8XX.SYS driver is named "Symbios PCI (53C8XX)" for driver installation. It supports the following devices and their associated LSI Logic host adapters: 4-4 Windows NT 4.0 Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation.

It supports the following devices and their associated LSI Logic host adapters: * * LSI53C895A (LSI8953U) LSI53C896 (LSI22910, LSI21002, LSI22902) The SYM_U3.SYS driver is named "Symbios Ultra3 PCI SCSI Driver" for driver installation. It supports the following devices and their associated LSI Logic host adapters: * * LSI53C1000 (LSI20160, LSI20160L) LSI53C1010 (LSI21040, LSI22915A, LSI22903, LSI21003, ITI6200U3LP). 4.1.3 Description The SYMC8XX.SYS, SYM_HI.SYS, and SYM_U3.SYS drivers meet the Microsoft specification for miniport drivers. These drivers allow connection of SCSI devices including disk drives, CD-ROMs, and tape drives for PCI-based machines. To support a new SCSI device, the Windows NT architecture requires that a class driver for that type device be present (usually supplied by Microsoft, or possibly by the peripheral manufacturer). No changes to SYMC8XX.SYS, SYM_HI.SYS, or SYM_U3.SYS are required. These drivers Introduction Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 4-5 are only supported under Windows NT 4.0 and later versions. They do not run under earlier versions of Windows NT. A Windows application passes SCSI commands to the SCSI devices by using the SCSI pass-through facility. Refer to the Microsoft Windows NT 4.0 documentation for more information. This facility allows applications to directly control and access SCSI devices by filling in a data structure and calling into the port driver or class driver. The SYMC8XX.SYS and SYM_HI.SYS drivers support Ultra SCSI protocol, providing twice the raw data transfer rate of Fast SCSI. These drivers also support Ultra2 SCSI protocol, providing quadruple the raw data transfer rate of Fast SCSI. The SYM_U3.SYS driver supports the Ultra160 SCSI protocol providing up to 160 Mbytes/s data transfer rates using double transition clocking. Ultra160 also includes CRC, PPR, and Domain Validation. The Ultra160 SCSI protocol performs 80 megatransfers per second resulting in approximately double the synchronous data transfer rates of Ultra2 SCSI. Caution: Ultra SCSI requires more stringent SCSI bus cabling setups than Fast SCSI. Ultra2 and Ultra160 require LVD termination. The SDMS driver bundled in Windows NT 4.0 is named SYMC810.SYS. When Windows NT selects the bundled SDMS driver during setup, the driver information (that is, "Symbios C810 PCI SCSI Host Adapter") appears. Although this implies that the driver only supports the LSI53C810, it actually supports the LSI53C810, LSI53C810A, LSI53C815, LSI53C825, LSI53C825A, LSI53C860, LSI53C875, and LSI53C876. This bundled driver does not "see" or "support" the LSI53C885, LSI53C895, LSI53C896, LSI53C895A, LSI53C1000, and LSI53C1010 chipsets and any newer host adapters based on these chipsets that LSI Logic currently produces. Note: Keep in mind that the Windows NT 4.0 setup only displays the driver information, not every controller found by that driver. 4-6 Windows NT 4.0 Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation.

Reboot your computer to load the new miniport driver(s). 4.4 Performance Tuning for Windows NT 4.0 Windows NT 4.0 has registry entries that can be used to increase the performance of SCSI I/O for certain configurations. The tunable parameters include large transfer block size support and a guaranteed number of concurrent I/Os for a particular SCSI bus. 4.4.1 Supporting Large Block Size The SYMC8XX.SYS, SYM_HI.SYS, and SYM_U3.SYS drivers can support up to a 1 Mbyte transfer size in Windows NT 4.0. However, in Windows NT 4.0, the default transfer size is 64 Kbytes. To enable a larger transfer size, an entry must be added to the registry by using the SYM_256K.REG file. This file will set a 256 Kbytes maximum, but it can be edited to set other desired maximum transfer sizes. Important: Be sure to read the information in the SYM_256K.REG data file before editing it. Choose one of two methods to add this registry setting: 1. Locate the SYM_256K.REG data file (supplied with the driver files) using Windows Explorer and double click on the file. or 2. Type at the command prompt: REGEDIT SYM_256K.REG This inserts an entry into the registry to enable 256 Kbytes block size support. Editing the SYM_256K.REG file can set any maximum block size between 64 Kbytes and 1 Mbyte (- 8 Kbytes). The formula to calculate the proper value for MaximumSGList is: MaximumSGList = (Maximum Block Size)/4K +1 Performance Tuning for Windows NT 4.0 Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 4-13 For 256 Kbytes: 256 Kbytes/4 Kbytes = 64, add 1 for 65 (decimal) or 0x41 (hexadecimal). The maximum value allowed for MaximumSGLIst is 255 or 0xFF. This denotes an absolute maximum transfer size of 1040384, which is 8 Kbytes less than 1 Mbyte (1040384/4K = 0xFE, add 1 for 0xFF or 255). Reboot your system for the new registry setting to be effective. To reset the maximum block size to the default of 64 Kbytes, follow the instructions above, and use SYMDFBLK.REG as the data file. 4.4.2 Maximum Number of Concurrent I/Os (Guaranteed) Windows NT 4.0 only guarantees a maximum of 32 concurrent I/Os active on a particular SCSI bus. However, due to the method of memory allocation, the actual limit of concurrent I/Os can vary greatly between various drivers or versions of drivers. This can have a huge impact on performance benchmarking between different driver versions or adapter vendors. In effect, one adapter may actually be able to have 70 or 80 I/Os outstanding, while another adapter could only have 32. This can affect systems with high performance storage subsystems, such as disk arrays. Important: Be sure to read the information in the SYM100IO.REG data file before editing it. In order to have a guaranteed number of concurrent I/Os, an entry must be added to the registry, using the SYM100IO.REG. file for the SDMS miniport drivers. Choose one of two methods to add this registry setting: 1. Locate the SYM100IO.REG data file (supplied with the driver files) using Windows Explorer and double click on the file. or 2. Type at the command prompt: REGEDIT SYM100IO.REG This inserts an entry in the registry to guarantee a maximum of 100 concurrent I/Os per adapter. If a maximum other than 100 is desired, the SYM100IO.REG file can be edited. The system administrator should be aware that increasing the 4-14 Windows NT 4.0 Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. number of concurrent I/Os from the default of 32 will use increasing amounts of nonpaged pool memory. High values for this setting can degrade system performance. Reboot the system for the new registry setting to be effective. To reset the guaranteed number of concurrent I/Os to the default of 32, follow the instructions above, and use the SYMDEFIO.REG data file. 4.4.2.1 Auto Request Sense Enabling and Disabling Auto Request Sense is found in Section 4.5, "Troubleshooting." 4.4.3 Disk Mirroring This section applies only to Intel x86 platforms where the SDMS 4.XX SCSI BIOS is used. The SDMS 4.XX SCSI BIOS loads only one image into system memory at boot time regardless of how many host adapters are used in the system. All of the disk drives on all host adapters are recognized through the INT13h function call. Due to this implementation, disk mirroring under Windows NT needs to be done if it is desired. Disk mirroring allows booting from the mirrored partition in case the primary partition fails. Note: These instructions may be different from Microsoft documentation. To create an NT Fault Tolerant (FT) diskette, follow these instructions: Step 1. Format a diskette in drive A: using NT (File Manager or Windows Explorer) for use as a FT boot floppy. Step 2. Copy NTLDR, NTDETECT.COM, and BOOT.INI from the root directory of the primary partition to this diskette. Step 3. Temporarily remove the read only attribute of the BOOT.INI file so that it can be modified and saved. Step 4. Edit BOOT.INI on the FT diskette and modify the following line where you want to boot the mirrored partition. MULTI(0)DISK(0)RDISK(X)PARTITION(Y)\ Performance Tuning for Windows NT 4.0 Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 4-15 multi(0) and disk(0) should always remain the same, and X = the drive number of the mirrored partition in the INT13h chain minus 80h. The drive number of the mirrored partition can be found during system bootup of the SDMS 4.XX SCSI BIOS when the primary partition does not exist. It should say either BOOT (= 80h), 81h, 82h, and higher. Therefore, the value of X would be 0 when BOOT, 1 when 81h, 2 when 82h, etc. Y = the partition number on the drive (starts at 1 which equals single partition on the drive) The next example provides a scenario to better illustrate the above information. Example: Two LSI Logic 8XX host adapters are in the system. The first host adapter, #0 which is the boot path, has two SCSI hard drives on ID 0 and ID 5. The second host adapter, #1, has two SCSI hard drives on ID 2 and ID 4. Assuming that the SCSI bus scan starts from ID 0 and goes up, the drive number of INT13h will look like this: Host Adapter #0, ID 0 = BOOT (which is 80h) Host Adapter #0, ID 5 = 81h Host Adapter #1, ID 2 = 82h Host Adapter #1, ID 4 = 83h Now Windows NT is installed on the boot drive, host adapter #0 ID 0, and a mirrored partition is established on host adapter #1 ID 2. If the primary partition fails, for example due to power failure, then the drive number of INT13h will change: Host Adapter #0, ID 5 = BOOT (which is 80h) Host Adapter #1, ID 2 = 81h Host Adapter #1, ID 4 = 82h Therefore, to boot from the mirrored partition, enter this line in the BOOT.INI file on the NT FT boot floppy: MULTI(0)DISK(0)RDISK(1)PARTITION(1)\ Windows NT 4.0 Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. Step 5. Save the BOOT.INI file and restore the "read only" attribute. 4.5 Troubleshooting Some potential problems and their suggested solutions are: During installation, no SCSI devices are found. * * * * * * Ensure that the custom setup is chosen on the Setup Method screen. Ensure that all devices are powered on and terminated correctly. Check that no devices have duplicate SCSI IDs. Make sure INTA is assigned for the PCI slot(s) where your SCSI host adapter(s) are installed. Ensure that all devices can be seen in the display banner of the SDMS SCSI BIOS at boot time. For systems with some versions of the Award BIOS, ensure that the PCI IRQ is set to edge triggered. System crashes during installation with a message indicating inaccessible boot device. * This error is usually associated with an IRQ, DMA channel, I/O (chip) address, or BIOS address conflict. Set the SCSI host adapter to use a different interrupt through the system BIOS in CMOS. A virus sometimes causes this error that infects the Master Boot Record of the boot device. Use a write-protected DOS bootable flex containing virus scanning and cleaning software to check for any viruses on the boot device, and remove if any are found. * A disk drive is recognized as seven different devices when only one is physically connected to the SCSI bus. Older SCSI devices that incorrectly indicate to Windows NT that they support multiple LUNs usually cause this error. * * Contact the device manufacturer for a firmware upgrade. Ensure that there are no devices with the same SCSI ID as the host adapter board. Troubleshooting Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 4-17 Problems with SCSI devices installation or operation. If a SCSI device is not operating properly (either the device is not found or a SCSI interface error occurs during scanning), it is possible that the third party device drivers do not support the auto request sense feature of LSI Logic host adapters. Disable the auto request sense feature as described below and try the device operation again. Step 1. To disable the auto request feature, use the SYMNO_AR.REG file supplied with the SDMS driver files for Windows NT, either double click the file in Windows Explorer/File Manager. or Type REGEDIT SYMNO_AR.REG at the command prompt. This inserts a registry entry that disables the auto request sense feature. The system must be rebooted for this change to take effect. Step 2. To re-enable the auto request sense feature, use the SYM_AUTO.REG file and perform one of the update methods as described in the preceding paragraph. Problems with certain SCSI devices when using an Ultra SCSI adapter. Some SCSI devices do not function properly when the adapter attempts to negotiate Ultra SCSI transfer rates. If a device is not operating properly, check the transfer speed setting using the SDMS 4.XX SCSI BIOS Configuration Utility (press Ctrl-C when the LSI Logic SDMS PCI BIOS banner appears during the system boot process). Devices that do not support Ultra SCSI should be set to a maximum of 10 Mbytes/s for 8-bits, or 20 Mbytes/s for 16-bits. Problems with Ultra SCSI devices using Ultra SCSI protocol. * If the system is configured with an LSI Logic host adapter that supports Ultra SCSI and an Ultra SCSI device is on the SCSI bus, intermittent problems and possible system crashes can occur if the SCSI bus cable and terminators do not conform to the Ultra SCSI specification. Disable Ultra SCSI support for all devices using the SDMS 4.XX SCSI BIOS Configuration Utility (press Ctrl-C when the LSI Logic PCI SCSI BIOS banner appears during the system boot process). * 4-18 Windows NT 4.0 Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. * If the system operates properly without Ultra SCSI enabled, it is highly likely that the SCSI bus cable and terminators are not configured correctly for Ultra SCSI. Refer to the appropriate LSI Logic Host Adapter User's Guide as listed in the Related Publications section on page v. At Ultra3 speed (160 Mbytes/s), the system hangs (waits forever), has a long boot time, or SCSI device is not available. Some older SCSI devices do not tolerate Domain Validation operations. At system boot time, Domain Validation is performed to test the data integrity of the SCSI bus between the host adapter and each target device. With some older SCSI devices, these operations can cause the device to stop responding to SCSI commands. To resolve this problem, disable Domain Validation either for a specific SCSI target or all adapters controlled by the driver. To do so, follow these steps: * To disable Domain Validation for a specific SCSI target, use the SDMS 4.XX PCI SCSI BIOS Configuration Utility to set the Sync Rate to 0 (async) and the Data Width to 8. This target will now run in async/narrow mode and no Domain Validation operations will be performed on it. To disable Domain Validation for all host adapters controlled by this driver, use the SYMNO_DV.REG file (supplied with the SDMS Windows NT driver files). Either double click on the file in Windows Explorer/File Manager or Type REGEDIT SYMNO_DV.REG at the command prompt. This inserts a registry entry that disables Domain Validation operations. You must reboot your system for the new registry setting to take effect. * * To re-enable the Domain Validation feature, use the SYM_DOMV.REG file and perform one of the update methods described in the preceding paragraph. Troubleshooting Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 4-19 4.6 Using the NT Configuration Utility You may use the NT Configuration Utility to change selected configuration parameters of LSI Logic SCSI host adapters. You must have installed Windows NT 4.0 and the latest SDMS Windows NT driver(s) (SYMC8XX.SYS, SYM_HI.SYS, or SYM_U3.SYS) to match your hardware prior to using this utility. You may decide to alter configuration values if a conflict exists between device settings or if you need to optimize system performance. You must reboot the system for the changes to take effect. During boot, the version number of Windows NT appears in a banner on the computer monitor. Important: The NT Configuration Utility may be used with Windows 2000 in conjunction with the following LSI Logic device drivers: SYMC8XX.SYS, version 4.16 or later, SYM_895A.SYS, version 4.16 or later, SYM_HI.SYS, version 4.16 or later SYM_U3.SYS, version 5.08 or later These drivers may be obtained from the LSI Logic Web site (www.lsilogic.com) or on the SDMS Software Device Drivers and Utilities CD-ROM, release 4.8. Since Windows NT and the SDMS Windows NT drivers do not need the adapter's BIOS to operate, only a limited number of the configuration parameters that can be changed by this utility will have any impact on the system once rebooted. These parameters are: * * * SCSI ID of the adapter Wide data bits setting Synchronous rate (Mbytes/s) If you have Windows NT 4.0 and are using the SDMS SYM_U3.SYS driver, the NT Configuration Utility allows you to perform Domain Validation testing on the installed LSI Logic LSI53C1000 or LSI53C1010 host adapter and connected devices. This testing verifies that the installed LSI Logic hardware functions correctly with the configuration information (synchronous speed and bus width) set through either the SCSI BIOS Configuration Utility or by using the capabilities of this utility. 4-20 Windows NT 4.0 Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. Changes to the wide data bit setting and/or synchronous rate can be made during this testing to ensure functionality. These settings can also be saved in a similar way as when doing the configuration settings. The difference when saving these new values during Domain Validation testing is that they are in effect immediately, and no system reboot is necessary. Important: The companion product to the NT Configuration Utility is the Domain Validation Utility, which monitors the SYM_U3.SYS miniport driver. Refer to Section 4.7, "Using the Domain Validation Utility," for more information. 4.6.1 Installing the NT Configuration Utility (x86 Platforms) You execute an InstallShield program to install the NT Configuration Utility. Use the SDMS Software Device Drivers and Utilities CD-ROM that contains the InstallShield program to perform the installation. Run the SETUP.EXE program directly from: {CD-ROM Drive Letter}: \UTILITY\WINDOWS\NTCONFIG\I386 A shortcut icon appears automatically on the desktop after installation. 4.6.2 Starting the NT Configuration Utility To start the NT Configuration Utility, double click on the shortcut icon. After a brief pause, your computer monitor displays the Main Menu of this utility. To make changes with this menu-driven utility, one or more LSI Logic SCSI host adapters installed in the system must have NVRAM to store the changes. Also, due to Windows NT constraints, each of the adapters must have at least one hard drive attached to it so that NT Configuration can properly identify the adapter. Important: The NT Configuration Utility is a powerful tool. The system can be rendered inoperable if care is not taken when reconfiguring the parameters. 4.6.2.1 Main Menu After starting the NT Configuration Utility, the Main menu appears and displays a summary list of all LSI Logic PCI to SCSI host adapters in Using the NT Configuration Utility Copyright (c) 1993-2001 by LSI Logic Corporation.

To abort any changes made on this screen, click on the Cancel button. When you click on OK or Cancel, the system returns to the Main menu. The settings in this menu are global settings that affect the selected host adapter and all SCSI devices attached to it. Table 4.3 provides a description of each setting. Table 4.3 Adapter Properties Fields and Descriptions Field Type [Value] Configuration [On/Off] Fields SCAM Support Descriptions Represents SCAM support and depends upon whether the BIOS issues or does not issue SCAM negotiations during initialization. Note: Windows NT does not support the use of SCAM. Turn this selection Off. Turning SCAM On may have adverse effects on your system. Parity Configuration [Enable/ Disable] Allows you to disable parity checking, since the LSI Logic PCI to SCSI host adapters always generate parity. Note that some older SCSI devices do not generate parity. Note: When disabling parity checking, you must also disable disconnects for all devices, as parity checking for the reselection phase is not disabled. If a device does not generate parity, and it disconnects, the I/O never completes because the reselection never completes. Host SCSI ID Configuration [0 to 7/ 0 to 15] Indicates the host adapter's SCSI ID, which is a unique number used to identify the device on the SCSI bus. Note: In general, LSI Logic suggests that you do not change the host adapter ID from the default value of 7, as this gives it the highest priority on the SCSI bus. Note that if you have 8-bit SCSI devices, these devices cannot see host IDs greater than 7. Scan Order Configuration [Low to High (0 .. Max)/ High to Low (Max .. 0)] Allows you to tell your device drivers to scan the SCSI bus from low-tohigh (0 .. max) SCSI ID, or from high-to-low (max to 0) SCSI ID. If you have more than one device on the SCSI bus, changing the scan order changes the order in which drive letters are assigned by the system. Note: This scan order option may conflict with operating systems that automatically assign a drive order. Using the NT Configuration Utility Copyright (c) 1993-2001 by LSI Logic Corporation.

Use the scroll bar on the right side of the Device Selections menu to scroll down the list of possible SCSI IDs/devices. Table 4.4 provides a description of the fields on this menu. Table 4.4 Device Selections Fields and Descriptions Field Type [Value] Fields Sync Rate (Mbytes/s) Descriptions Configuration Indicates the maximum data transfer rate the host adapter will [20, 40, 80...] attempt to negotiate. The host adapter and a SCSI device must agree to a rate they can both handle. The width column affects this value. Configuration Indicates the maximum SCSI data width the host adapter will attempt to negotiate. The host adapter and a SCSI device must agree to a width they can both handle. Only host adapters that can do 16-bit data transfers have this option enabled. Tells the host adapter whether or not to allow a device to disconnect. SCSI devices have the ability to disconnect from the initiator during an I/O transfer. This disconnect frees the SCSI Bus to allow other I/O processes. Some devices run faster with disconnects enabled (mostly newer devices), while some run faster with disconnects disabled (mostly older devices). Sets the amount of time the host adapter waits for a read, write, or seek command to complete before trying the I/O transfer again. Since this provides a safeguard that allows the system to recover if an I/O operation fails, LSI Logic recommends that you always set the time-out to a value greater than zero. Set this option to No when you do not want a specific device available to the system. Also, on a bus with only a few devices attached, you can speed up boot time by changing this setting to No for all unused SCSI IDs. Set this option to No if you have problems with a device that responds to all LUNs whether they are occupied or not. For example, if there is a SCSI device with multiple LUNs but you do not want all of those LUNs to be available to the system, then set this option to No. This will limit the scan to LUN 0 only.

Table 4.6 Fields Back-to-Back Inquiries Test Procedures Fields and Descriptions Descriptions This test issues two inquiries to the selected device. The first inquiry occurs after negotiating Async/Narrow, while the second inquiry occurs after negotiating with the passed values. The Inquiry data from the two are then compared. If a miscompare is noted, the test fails. I/O errors can also cause this test to fail. You may wish to execute the test again after stepping down the Sync Speed and/or Bus Width negotiation value(s). This test issues write buffer commands to the device using the data pattern you have chosen. A read buffer command is then issued to read the data back. A data comparison is then done to verify data transfer. If a miscompare is noted, the test fails. The negotiation values used for both commands are your specified values. I/O errors can also cause this test to fail. You may wish to execute the test again after stepping down the Sync Speed and/or Bus Width negotiation value(s). This test also issues write/read buffer command pairs. Instead of using the pattern specified by you, this test loops through sending I/O pairs and doing data compares using each of the possible patterns. Each pattern will have been used 10 times by the end of this loop. If a miscompare is noted, the test fails. The test finishes by doing 32 random reads to the device media to further stress the bus. The negotiation values used for the commands are your specified values. The values specified for the LVD driver signal and Req/Ack Skew value are also passed to the miniport driver during this test. I/O errors can cause this test to fail. You may wish to execute the test again after stepping down the Sync Speed and/or Bus Width negotiation value(s) and/or altering the LVD Driver Signal or Req/Ack Skewing value(s).

The ASPI software provides a mechanism used by Windows applications as an interface to access SCSI adapters and peripherals. Refer to the "ASPI for Win32," version 2.3 specification for additional details. 4.8.1 Features The ASPI for WIndows NT 4.0 supports these features: * * * * * Provides information about SCSI adapters Provides information about SCSI devices Use to issue SCSI I/O requests Multithreaded and multitasking operations 32-bit Windows applications 4.8.2 Description SDMS NT ASPI conforms to the Advanced SCSI Programming Interface (ASPI) version 2.3 specification. Windows applications can use this interface to gain access to system SCSI devices. Additionally, Windows applications can retrieve information about installed SCSI adapters and the SCSI peripherals attached to the adapters. Applications using the ASPI interface can also issue SCSI I/O requests to the devices. Note that Using SDMS ASPI for Windows NT 4.0 Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 4-33 NT ASPI is one method to use for gaining access to SCSI devices; the other method would be to use SCSI pass-through commands. Typical of these types of applications are utility programs that investigate and explore SCSI devices or applications such as CD-ROM mastering software and scanner applications. SDMS NT ASPI is comprised of two modules: a user mode DLL, and a kernel mode device driver. The DLL mode passes commands and makes requests to the kernel mode device driver, which in turn interfaces with the Windows NT operating system for execution of the request. A current version of NT ASPI can be downloaded from the LSI Logic Web site (http://www.lsilogic.com). After you are connected to this Web site, place your cursor on the Get Drivers option in the menu bar. Click on the Drivers selection. Choose the Utilities for SCSI and click on the Go button. Follow the instructions on subsequent screens to download NT ASPI. 4.8.3 Installing NT ASPI To install the NT ASPI software, you execute an InstallShield setup program. If you obtained the software from the LSI Logic web site, it is within a selfextracting zip file. Expand the zip file to install the software into a directory on your hard disk drive or to a diskette, and then run SETUP.EXE. If you obtained the software from the SDMS Software Device Drivers and Utilities CD-ROM, run the SETUP.EXE program directly from: {CD-ROM Drive Letter}:\UTILITY\WINDOWS\NTASPI The setup program installs the NT ASPI files into the proper directories as well as making the appropriate registry entries. After installing the software, you must reboot the computer. There are no command line options with the NT ASPI software. 4.9 Using SCSI Tools for Windows NT SDMS SCSI Tools for Windows NT is a software support utility for x86 platforms. It provides a mechanism for examining host adapters and SCSI devices within the Windows NT environment. 4-34 Windows NT 4.0 Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation.

Chapter 5 Windows 2000 Device Driver Installation This chapter describes the device drivers for the Windows 2000 operating system. It provides installation instructions for new and existing system installations. This chapter includes these topics: * * * * * * * Section 5.1, "Introduction," page 5-1 Section 5.2, "Using the SDMS Windows 2000 Drivers," page 5-4 Section 5.3, "Installing Drivers for Windows 2000," page 5-6 Section 5.4, "Performance Tuning for Windows 2000," page 5-10 Section 5.5, "Troubleshooting," page 5-14 Section 5.6, "Using SDMS ASPI for Windows 2000," page 5-18 Section 5.7, "Using SCSI Tools for Windows 2000," page 5-20 5.1 Introduction Windows 2000 is an operating system designed to run on Intel architecture processors using current technology. It provides a GUI environment that incorporates many high-level features (refer to the Microsoft Windows 2000 documentation for details). An I/O manager handles I/O requests in Windows 2000. To address a SCSI peripheral, the I/O manager goes through the appropriate drivers. Windows 2000 provides class drivers for hard disk, floptical, CD-ROM, printer, and scanner peripherals. Other class drivers, provided by peripheral manufacturers, may be added to support new devices. Tape device support is built into the operating system itself and does not require a class driver. Microsoft provides the port driver and LSI Logic provides the miniport drivers, which are called SYMC8XX.SYS, SYM_HI.SYS, SYM_895A.SYS and PCI Storage Device Management System SDMS 4.0 User's Guide Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 5-1 SYM_U3.SYS. The SYMC8XX.SYS and SYM_HI.SYS drivers are bundled with the Windows 2000 operating system. The SYM_895A.SYS and SYM_U3.SYS drivers are nonbundled drivers. These miniport drivers complete the path to an LSI Logic controller or processor with an optional SDMS SCSI BIOS. LSI Logic uses the same filenames for their drivers for different Windows operating systems. The driver files are packaged either in separate subdirectories based on the Windows operating system or on different flex disks. To determine the driver file for Windows 2000, note that the filename ends with .SYS. For example, SYMC8XX.SYS. (The same is true for Window NT 4.0). To determine the operating system version, go into Windows Explorer, display the driver file, right click on the filename, click on Properties, and click on the Version tab. Finally, click on the Internal Filename in the lower section. For Windows 2000, the filename appears as filename (NT 5.0). For example, SYMC8XX.SYS (NT 5.0). The sections below describe these drivers and their installation. 5.1.1 Features The SDMS device drivers for Windows 2000 support these features: * * * * * * * * * * * * Ultra160 data transfers (for LSI53C1000 and LSI53C1010) Domain Validation (for SYM_U3.SYS driver only) Cyclic Redundancy Check (CRC) (for SYM_U3.SYS driver only) Parallel Protocol Request (PPR) (for SYM_U3.SYS driver only) Synchronous negotiation (including Fast SCSI, Ultra SCSI, Ultra2 SCSI) Wide negotiation Tagged-command queuing Multiple host adapters Multiple LUNs Disconnect/Reselect Scatter/Gather Differential support 5-2 Windows 2000 Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation.

Click on the Go button. Follow the instructions on subsequent screens to download the drivers. 5-4 Windows 2000 Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 5.2.2 Description The SYMC8XX.SYS, SYM_HI.SYS, SYM_895A.SYS, and SYM_U3.SYS drivers meet the Microsoft specification for miniport drivers. Miniport drivers allow the connection of SCSI devices including disk drives, CD-ROMs, and tape drives for PCI-based machines. To support a new SCSI device, the Windows 2000 architecture requires that a class driver for that type device be present (usually supplied by Microsoft, or possibly by the peripheral manufacturer). No changes to these drivers are required. The SYMC8XX.SYS, SYM_HI.SYS, SYM_895A.SYS, and SYM_U3.SYS drivers described by this document support Windows 2000 only. The SYM_895A.SYS driver is available for Windows 2000 only. Note: The SYM_HI.SYS driver for Windows NT 4.0 supports the LSI53C895A (LSI8953U). Additionally, there are other versions of the SYMC8XX.SYS, SYM_HI.SYS, and SYM_U3.SYS drivers that are supported under Windows NT 4.0. A Windows application passes SCSI commands directly to the SCSI devices by using the SCSI pass-through facility (refer to the Microsoft Windows 2000 documentation for details). This facility allows applications to directly control and access SCSI devices by filling in a data structure and calling into the port or class driver. The SYMC8XX.SYS, SYM_HI.SYS, and SYM_895A.SYS drivers support Ultra SCSI protocol. This protocol provides twice the raw data transfer rate of Fast SCSI for disk drives and LSI Logic host adapters that support Ultra SCSI. These drivers also support Ultra2 protocol, providing quadruple the raw data transfer rate of Fast SCSI. The SYM_U3.SYS driver supports Ultra160 SCSI protocol providing speeds up to 160 Mbytes/s data transfer rates using double transition clocking. Ultra160 also provides CRC, PPR, and Domain Validation. The Ultra160 SCSI protocol performs 80 megatransfers per second resulting in approximately double the synchronous data transfer rates of Ultra2 SCSI. Caution: Ultra SCSI requires more stringent SCSI bus cabling setups than Fast SCSI, Ultra2, and Ultra160 SCSI require LVD termination.

Use this procedure when installing Windows 2000 onto an unused SCSI drive. Windows 2000 automatically adds the driver to the registry and copies the driver to the appropriate directory. Refer to the Microsoft documentation about using boot floppy diskettes as a method of installation. 5.3.1.1 CD-ROM Installation The SYMC8XX.SYS and SYM_HI.SYS drivers are bundled with Windows 2000. These drivers support the LSI53C8XX family of LSI Logic controllers, with the exception of the LSI53C895A. The SYM_895A.SYS and SYM_U3.SYS drivers are nonbundled drivers. The SYM_895A.SYS driver supports the LSI53C895A controller. The SYM_U3.SYS driver supports the LSI53C1000 and LSI53C1010 controllers. To install Windows 2000 on a new system, the system BIOS must support booting from a CD-ROM. SDMS BIOS settings may need to be changed to allow CD-ROM booting. Step 1. Start the Windows 2000 installation by booting from the Windows 2000 CD-ROM. Note: If only the SYMC8XX.SYS and/or SYM_HI.SYS drivers are needed, no user action is required as they will be loaded from the CD-ROM automatically. Step 2. Press the F6 key to install the SYM_895A.SYS or SYM_U3.SYS nonbundled drivers. 5-6 Windows 2000 Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. Note: Be sure to press the F6 key as any driver loaded later in the installation process is not recognized by the Windows setup. If F6 is not pressed, all devices controlled by the drivers are not available during Windows 2000 setup. Step 3. Choose S to specify an additional device when the screen displays Setup could not determine the type of one or more mass storage devices.... Note: If this screen is not displayed as the first user input, then the F6 keypress was not seen by the setup program. Reboot your system and try again. The system prompts for the manufacturer-supplied hardware support disk. Step 4. Insert the appropriate SDMS driver diskette containing the Windows 2000 driver required to support your LSI Logic adapter(s) and press Enter. Step 5. Press Enter to proceed when the selected driver is shown highlighted. Return to the Windows 2000 Setup screen. Note: If both SDMS drivers need to be installed, they can be installed one after the other using Step 3 through Step 5. Installation order is not important. Step 6. Press Enter to proceed. The message about setup loading files appears. Step 7. Follow the Microsoft Windows 2000 installation procedure at this point. 5.3.2 Existing System Installation This procedure installs or upgrades the SYMC8XX.SYS, SYM_HI.SYS, SYM_895A.SYS and/or SYM_U3.SYS drivers onto an existing Windows 2000 system. When you add an LSI Logic adapter to an existing system, the new adapter is automatically detected at the next reboot. For adapters controlled by the SYMC8XX.SYS or SYM_HI.SYS drivers, the bundled driver is loaded automatically with no user intervention. For adapters controlled Installing Drivers for Windows 2000 Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 5-7 by the SYM_895A.SYS or SYM_U3.SYS drivers, the Device Driver Wizard will appear at boot. Click on the Next button and continue at Step 8. Step 1. Boot Windows 2000 and log on as Administrator. Step 2. Right click on My Computer and click on Properties. Step 3. Click on the Hardware tab, and then click on the Device Manager button. Step 4. Click the "+" to the left of the SCSI and RAID controllers line. Find the adapter desired for the driver upgrade and double click on the entry. Step 5. Click on the Driver tab. Information on the currently installed driver is displayed, and additional driver details can be viewed by clicking the Driver Details button. Step 6. Click on the Update Driver button to update the existing driver. The Upgrade Device Driver Wizard begins. Step 7. Click on the Next button. Step 8. Make sure "Search for a suitable driver for my device" is selected, then click on the Next button. Step 9. Make sure the "Floppy disk drives" location is checked. Step 10. Insert the appropriate SDMS driver diskette that contains the Windows 2000 driver required to support your LSI Logic adapter(s) and press Enter. The system scans the existing driver database and the floppy disk drive for drivers for the selected adapter. If a driver already exists on the system, and it is newer than the updated driver on the SDMS driver diskette, a message appears and gives you the option to keep or reinstall the existing driver. In this case, if you desire to use the upgrade driver anyway, click the "Install one of the other drivers" box, then click on the Next button. If no current driver exists, the driver on the SDMS driver diskette is displayed. Step 11. Click on the Next button. 5-8 Windows 2000 Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. A list of suitable drivers appears. The entry for the upgrade driver can be verified by scrolling the display to the right, and viewing the Location field. Step 12. Highlight the driver for the upgrade installation disk and click on the Next button. In some cases, a message will state that this driver is not digitally signed. This message informs you that a nonsigned driver is being installed. Note: Drivers are digitally signed by the Microsoft Windows Hardware Quality Lab (WHQL). Due to the time lag between the general customer release by LSI Logic of Windows drivers and the completion of WHQL testing, some drivers that are distributed with adapters or downloaded from the LSI Logic Web site may not be digitally signed. Step 13. Click No to cancel the installation if the nonsigned driver is not desired or click Yes to continue the installation. The system loads the driver from the SDMS driver diskette. A message box may appear indicating that the target (existing) driver is newer than the source (upgrade) driver. Step 14. Click No to cancel the driver upgrade at this point or click Yes to continue the installation. The system copies the driver to the system disk. For any adapter other than the boot adapter, the updated driver becomes active immediately. For the boot adapter, a message box displays indicating that you must reboot your system for the new driver to take effect. Step 15. Click on the Finish button to complete the driver upgrade. When upgrading the driver on a multiple SCSI channel adapter, both channels of the adapter should be upgraded before the system is rebooted. Failure to do this can result in the upgraded driver being replaced by the original existing driver. Installing Drivers for Windows 2000 Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 5-9 5.4 Performance Tuning for Windows 2000 Windows 2000 has registry entries that can be used to improve the performance of SCSI I/O for certain configurations. The tunable parameters are large transfer block size support and a guaranteed number of concurrent I/Os for a particular SCSI bus. Important: Registry files for the SYMC8XX.SYS, SYM_HI.SYS, and SYM_895A.SYS and SYM_U3.SYS drivers begin with SYMXXXXX.REG. 5.4.1 Large Block Size Support The SYMC8XX.SYS, SYM_HI.SYS, SYM_895A.SYS, and SYM_U3.SYS drivers can support up to a 1 Mbyte transfer size in Windows 2000, however the default transfer size is limited to 64 Kbytes. To enable a larger transfer size, an entry must be added to the registry, using the file SYM_256K.REG. This file sets a 256 Kbytes maximum, but it can be edited to set other desired maximum transfer sizes. Important: Be sure to read the information in the SYM_256K.REG data file before editing it. Choose one of two methods to add this registry setting: 1. Locate the SYM_256K.REG data file (supplied with the driver files) using Windows Explorer and double click on the file. or 2. Type at the command prompt: REGEDIT SYM_256K.REG This inserts an entry in the registry to enable 256 Kbytes block size support. Editing the SYM_256K.REG file can set any maximum block size between 64 Kbytes and 1 Mbyte (- 8 Kbytes). The formula to calculate the proper value for MaximumSGList is: MaximumSGList = (Maximum Block Size)/4K +1 For 256 Kbytes: 256K/4K = 64 Kbytes, add 1 for 65 (decimal) or 0x41 (hexadecimal). The maximum value allowed for MaximumSGLIst is 5-10 Windows 2000 Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 255 or 0xFF. This denotes an absolute maximum transfer size of 1040384, which is 8 Kbytes less than 1 Mbyte (1040384/4K = 0xFE, add 1 for 0xFF or 255). You must reboot your system for the new registry setting to take effect. To reset the maximum block size to the default of 64 Kbytes, follow the instructions above, except use SYMDFBLK.REG as the data file. 5.4.2 Maximum Number of Concurrent I/Os (Guaranteed) Windows 2000 only guarantees a maximum of 32 concurrent I/Os active on a particular SCSI bus. However, due to the method of memory allocation, the actual limit of concurrent I/Os can vary greatly between various drivers or versions of drivers. This can have a huge impact on performance benchmarking between different driver versions or adapter vendors. In effect, one adapter may actually be able to have 70 or 80 I/Os outstanding, while another adapter could only have 32. This can also affect systems with high performance storage subsystems, such as disk arrays. In order to have a guaranteed number of concurrent I/Os, an entry must be added to the registry, using the SYM100IO.REG file. Important: Be sure to read the information in the SYM100IO.REG data file before editing it. Choose one of two methods to add this registry setting: 1. Locate the SYM100IO.REG (supplied with the driver files) using Windows Explorer and double click on the file. or 2. Type at the command prompt: REGEDIT SYM100IO.REG This inserts an entry in the registry to guarantee a maximum of 100 concurrent I/Os per adapter. If a maximum other than 100 is desired, the SYM100IO.REG file can be edited. However, setting this value to a high number uses increasing amounts of nonpaged pool memory, a critical Windows 2000 resource. High values for this setting can degrade system performance. Performance Tuning for Windows 2000 Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 5-11 You must reboot your system for the new registry setting to take effect. To reset the guaranteed number of concurrent I/Os to the default of 32, follow the instructions above, except use SYMDEFIO.REG as the data file. 5.4.3 Auto Request Sense Enabling and Disabling Auto Request Sense is found in Section 5.5, "Troubleshooting." 5.4.4 Disk Mirroring This section applies only to Intel x86 platforms where the SDMS 4.XX PCI SCSI BIOS is used. The SDMS 4.XX PCI SCSI BIOS loads only one image into system memory at boot time regardless of how many host adapters are used in the system. All of the disk drives on all host adapters are recognized through the INT13h function call. Due to this implementation, disk mirroring under Windows 2000 could be done if it is desired. Disk mirroring allows booting from the mirrored partition in case the primary partition fails. Note: These instructions may be different from Microsoft documentation. To create a Windows 2000 Fault Tolerant (FT) diskette, follow these instructions: Step 1. Format a diskette in drive A: by using Windows 2000 (Windows Explorer or My Computer) for use as a FT boot floppy. Step 2. From the root directory of the primary partition, copy NTLDR, NTDETECT.COM, and BOOT.INI to this diskette. Step 3. Temporarily remove the read only attribute of the BOOT.INI file so that it can be modified and saved. Step 4. Edit the BOOT.INI file on the FT diskette and modify the following line where you want to boot the mirrored partition: multi(0)disk(0)rdisk(x)partition(y)\ 5-12 Windows 2000 Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. The drive number of the mirrored partition can be found during system bootup of the SDMS 4.XX PCI SCSI BIOS when the primary partition does not exist. It should say either BOOT (= 80h), 81h, 82h, or higher. Therefore, the value of X would be 0 when BOOT, 1 when 81h, 2 when 82h, etc. Y = the partition number on the drive (starts at 1 which equals single partition on the drive). Step 5. The next example provides a scenario to better illustrate the above information. Example: Two LSI Logic 8xx host adapters are in the system. The first host adapter, #0 which is the boot path, has two SCSI hard drives on ID 0 and ID 5. The second host adapter, #1, has two SCSI hard drives on ID 2 and ID 4. Assuming that the SCSI bus scan starts from ID 0 and goes up, the drive number of INT13h will look like this: Host Adapter #0, ID 0= BOOT (which is 80h) Host Adapter #0, ID 5= 81h Host Adapter #1, ID 2= 82h Host Adapter #1, ID 4= 83h Now Windows 2000 is installed on the boot drive, host adapter #0 ID 0, and a mirrored partition is established on host adapter #1 ID 2. If the primary partition fails, for example due to power failure, then the drive number of INT13h will change: Host Adapter #0, ID 5= BOOT (which is 80h) Host Adapter #1, ID 2= 81h Host Adapter #1, ID 4= 82h Therefore, to boot from the mirrored partition, enter this line in the BOOT.INI file on the Windows 2000 FT boot floppy: multi(0)disk(0)rdisk(1)partition(1)\ Performance Tuning for Windows 2000 Copyright (c) 1993-2001 by LSI Logic Corporation.

Follow the Microsoft Windows 2000 installation procedure at this point. Troubleshooting Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 5-15 When the installation has completed, you can move the files from the Windows NT (WINNT) folders to appropriate folders within the Windows 2000 (WIN2K) folder. During installation, no SCSI devices are found. * * * * * * Ensure that the custom setup is chosen on the Setup Method screen. Ensure that all devices are powered on and terminated correctly. Check that no devices have duplicate SCSI IDs. Make sure INTA is assigned for the PCI slot(s) where your SCSI host adapter(s) are installed. Ensure that all devices can be seen in the display banner of the SDMS SCSI BIOS at boot time. For systems with some versions of the Award BIOS, ensure that the PCI IRQ is set to edge triggered. System crashes during installation with a message indicating inaccessible boot device. * This error is usually associated with an IRQ, DMA channel, I/O (chip) address, or BIOS address conflict. Set the SCSI host adapter to use a different interrupt. A virus sometimes causes this error that infects the Master Boot Record of the boot device. Use a write protected DOS bootable flex containing virus scanning and cleaning software to check for any viruses on the boot device, and remove if any are found. * A disk drive is recognized as seven different devices when only one is physically connected to the SCSI bus. Older SCSI devices that incorrectly indicate that they support multiple LUNs to Windows 2000 usually cause this error. * * Contact the device manufacturer for a firmware upgrade. Ensure that there are no devices with the same SCSI ID as the host adapter board. 5-16 Windows 2000 Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. Problems with SCSI devices installation or operation. If a SCSI device is not operating properly (either the device is not found or a SCSI interface error occurs during scanning), it is possible that the third party device drivers do not support the auto request sense feature of LSI Logic host adapters. Disable the auto request sense feature as described below and try the device operation again. Step 1. To disable the auto request sense feature, use the SYMNO_AR.REG file (supplied with the SDMS driver installation files). Either double click on the file in Windows Explorer or type REGEDIT SYMNO_AR.REG at the command prompt. This inserts a registry entry that disables the auto request sense feature. You must reboot your system for this change to take effect. Step 2. To re-enable the auto request sense feature, use the SYM_AUTO.REG file and perform one of the update methods described in the preceding paragraph. Problems with certain SCSI devices when using an Ultra SCSI adapter. Some SCSI devices do not function properly when the adapter attempts to negotiate Ultra SCSI transfer rates. If a device is not operating properly, check the transfer speed setting using the SDMS 4.XX PCI SCSI BIOS Configuration Utility (press Ctrl-C when the SDMS PCI SCSI BIOS banner appears during the system boot process). Devices that do not support Ultra SCSI should be set to a maximum of 10 Mbytes/s for 8-bits, and 20 Mbytes/s for 16-bits. Problems with Ultra160 SCSI devices using Ultra160 SCSI protocol. If the system is configured with an LSI Logic host adapter that supports Ultra160 SCSI and an Ultra160 SCSI device is on the SCSI bus, intermittent problems and possible system crashes can occur if the SCSI bus cable and terminators do not conform to the Ultra160 SCSI specification. * To disable Ultra160 SCSI support for all devices, use the SDMS 4.XX PCI SCSI BIOS Configuration Utility (press Ctrl-C when the SDMS PCI BIOS banner appears during the system boot process). Troubleshooting Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 5-17 * If the system operates properly without Ultra160 SCSI enabled, it is highly likely that the SCSI bus cable and terminators are not configured correctly for Ultra160 SCSI. See the LSI Logic host adapter user's guide for information on Ultra160 SCSI cabling requirements. At Ultra160 speed (160 Mbytes/s) system hangs, has long boot time, or SCSI device not available. Some older SCSI devices do not tolerate Domain Validation operations. At system boot time, Domain Validation is performed to test the data integrity of the SCSI bus between the host adapter and each target device. With some older SCSI devices, these operations can cause the device to stop responding to SCSI commands. Disable Domain Validation, either for a specific SCSI target or all adapters controlled by the driver, by following these steps: Step 1. To disable Domain Validation for a specific SCSI target, use the SDMS 4.XX PCI SCSI BIOS Configuration Utility to set the Sync Rate to 0 (async) and the Data Width to 8. This target will run in async/narrow mode and no Domain Validation operations will be performed on it. Step 2. To disable Domain Validation for all host adapters controlled by this driver, use the SYMNO_DV.REG file (supplied with the SDMS driver files). Either double click on the file in Windows Explorer or My Computer or type REGEDIT SYMNO_DV.REG at the command prompt. This inserts a registry entry that disables Domain Validation operations. You must reboot your system for this change to take effect. Step 3. To re-enable the Domain Validation feature, use the file SYM_DOMV.REG and perform one of the update methods described in the preceding paragraph. 5.6 Using SDMS ASPI for Windows 2000 SDMS ASPI for Windows 2000 is a software support package based on the "ASPI for Win32" version 2.3 specification. Refer to this specification 5-18 Windows 2000 Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. for additional information. The ASPI software provides a mechanism used by Windows applications as an interface to access SCSI adapters and peripherals. 5.6.1 Features The Windows 2000 ASPI software supports these features: * * * * * Information about SCSI adapters Information about SCSI devices Ability to issue SCSI I/O requests Multithreaded and multitasking operations 32-bit Windows applications 5.6.2 Description Windows 2000 ASPI meets the Advanced SCSI Programming Interface (ASPI) version 2.3 specification. All Windows applications use this interface to gain access to system SCSI devices. Applications using this interface can retrieve information about installed SCSI adapters and the SCSI peripherals attached to the adapters. Applications using the ASPI interface can issue SCSI I/O requests to the devices. Typical of these type of applications are utility programs that investigate and explore SCSI devices, or applications such as CD-R mastering software and scanner applications. Note that Windows 2000 ASPI is one method to use for gaining access to SCSI devices; the other method would be to use SCSI pass-through commands. Windows 2000 ASPI is comprised of two modules: 1. a user mode DLL, and 2. a kernel mode device driver Applications, using ASPI only, interface with the user mode DLL. The DLL passes commands and requests to the kernel mode device driver, which in turn interfaces with the Windows 2000 operating system for execution of the request. Note that nonadministrator users can now open the kernel mode driver. Using SDMS ASPI for Windows 2000 Copyright (c) 1993-2001 by LSI Logic Corporation.

Chapter 6 DOS Device Driver Installation This chapter describes the device drivers for the DOS operating systems. It provides installation instructions for these drivers along with utility information. This chapter includes these topics: * * * * * * Section 6.1, "Introduction," page 6-1 Section 6.2, "Using the DOS Installation Utility," page 6-3 Section 6.3, "About the ASPI8XX.SYS Driver," page 6-5 Section 6.4, "About the SYMDISK.SYS Driver," page 6-12 Section 6.5, "About the SYMCD.SYS Driver," page 6-18 Section 6.6, "Additional DOS Utilities," page 6-23 6.1 Introduction In SDMS 4.0, the SCSI BIOS for the LSI Logic family of PCI to SCSI chips is capable of mapping SCSI hard disk drives behind any non-SCSI hard disk drives (for example, IDE) within the same system. A driverless solution allows connection of up to 24 hard drives (SCSI and non-SCSI) under DOS 5.0 and above. The SCSI BIOS also supports full Virtual DMA Services (VDS), including features such as scatter/gather. To gain maximum performance, disable any double buffer option provided by disk caching software (such as the Microsoft SMARTDRV.EXE program) for all drives handled through SDMS. 6.1.1 When You Need to Load Drivers To connect peripherals other than hard disk drives, you must load the appropriate driver. Some of these drivers work together, and some are capable of direct communication with an LSI Logic PCI to SCSI controller.

Follow the instructions on subsequent screens to download the drivers. 6.1.2 LSI Logic Devices Supported All LSI Logic devices and host adapters have undergone a name change. They have transitioned from a SYM prefix to an LSI prefix. No name changes have occurred for the SDMS DOS drivers. The ASPI8XX.SYS, SYMDISK.SYS, and SYMCD.SYS drivers support the following devices and their associated LSI Logic host adapters: * * * * * * * * * * * * LSI53C810, LSI53C810A, LSI53C810AE (LSI8100S, LSI8100ASP, LSI20810) LSI53C815 (LSI815XS, LSI8150SP) LSI53C825, LSI53C825A (LSI8250S, LSI8251S, LSI8251D, LSI8250ASP, LSI8251ASP, LSI8251AD) LSI53C860, LSI53C860AE (LSI8600SP, LSI20860) LSI53C875, LSI53C875E (LSI8750SP, LSI8751SP, LSI8751SPE, LSI8751D) LSI53C876 (LSI22801, LSI22802) LSI53C885 LSI53C895 (LSI8951U, LSI8952U) LSI53C895A (LSI8953U) LSI53C896 (LSI22910, LSI21002, LSI22902) LSI53C1000 (LSI20160, LSI20160L) LSI53C1010 (LSI22915A, LSI21040, LSI22903, LSI21003, ITI6200U3LP) 6.2 Using the DOS Installation Utility The SDMS DOS Installation Utility provides a quick and easy method for performing either a default or custom installation of the SCSI device drivers in a DOS/Windows environment. It works with any system using an SDMS supported LSI Logic SCSI chip. The DOS Installation Utility Using the DOS Installation Utility Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 6-3 identifies the system, scans the SCSI bus, and properly installs the required SCSI device drivers. The SDMS Software Device Drivers and Utilities CD-ROM contains the DOS device drivers along with the DOS Installation Utility. To install the DOS Drivers using this utility, follow these steps: Step 1. Copy the contents from this directory on the SDMS CD-ROM {CD-ROM DRIVE LETTER}:\DRIVERS\DOS to the root of a diskette. Step 2. Reboot your system. Step 3. Insert the newly created diskette into your floppy drive (A: or B:), and type at a DOS prompt: INSTALL Step 4. Press Enter. Step 5. Follow the directions presented on the screen. When performing a custom installation, an understanding of the information presented in the following sections for manual installation may prove useful. 6.2.1 Troubleshooting Here is a potential problem and a suggested solution: If a menuing system exists in the CONFIG.SYS file and multiple menu selections are available that already include some of the SDMS drivers, the system only updates the first menu selection found that already contains our drivers rather than all of them. However, if SDMS drivers are not present, it puts the new drivers in the common area and creates a common menu item one, if it does not exist. A workaround regarding menuing in the CONFIG.SYS file is to ensure the install program puts the drivers where you want them. By default they are put in the common area. However, if some of the SDMS drivers are already present, the install program may incorrectly guess where the new ones should be put. 6-4 DOS Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation.

All rights reserved. 6-5 6.3.2 Description The ASPI8XX.SYS device driver is an ASPI manager that provides an interface to popular ASPI applications. This driver is required when you want to use SYMDISK.SYS or SYMCD.SYS or whenever you want to run an ASPI application. This interface replaces an SDMS BIOS (if present), and fully supports all devices supported by the BIOS. If an SDMS BIOS is not present, only an ASPI interface is provided. 6.3.3 Installing the ASPI8XX.SYS Driver To install the ASPI8XX.SYS driver, follow these steps: Step 1. Copy the ASPI8XX.SYS driver to the boot disk. The SDMS Software Device Drivers and Utilities CD-ROM contains the ASPI8XX.SYS driver in this directory: {CD-ROM Drive Letter}:\DRIVERS\DOS Step 2. Add this line to the system's CONFIG.SYS file: DEVICE=C:[path]ASPI8XX.SYS. This line must appear before any line loading other SDMS drivers (such as, SYMCD.SYS and/or SYMDISK.SYS), or any other ASPI compliant driver/application. 6.3.4 Using Command Line Options The ASPI8XX.SYS device driver has several configurable features that are set by using switches on the command line in the CONFIG.SYS file. Using these command line options overrides the settings in the SCSI BIOS Configuration Utility. Table 6.1 lists the command line options. No spaces are allowed within a single command line option, but spaces are required between different command line options. 6-6 DOS Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. In the following descriptions, path refers to the adapter number (boot order designation), and id refers to the SCSI ID. The following conventions are also used: [] * items in brackets are optional means repeat item 0 or more times Table 6.1 ASPI8XX Command Line Options Description Prevents a SCSI bus reset during loading of ASPI8XX.SYS. Activate this option by modifying the line in the CONFIG.SYS file that loads ASPI8XX.SYS to look like this: DEVICE=C:[PATH]ASP8XX.SYS /NORST Option Name /NORST /ASK Prompts at system bootup about loading the ASPI8XX.SYS driver. Activate this option by modifying the line in the CONFIG.SYS file that loads ASPI8XX.SYS to look like this: DEVICE=C:[PATH]ASPI8XX.SYS /ASK /WIDTH Defines the maximum data width negotiated with a device. This option can be used with host adapters capable of 16-bit data transfers. Valid settings are 8 or 16. Syntax: /WIDTH=n About the ASPI8XX.SYS Driver Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 6-7 Table 6.1 ASPI8XX Command Line Options (Cont.) Description Option Name /DISCONNECT Allows a device to disconnect. SCSI devices have the ability to disconnect from the or bus during an I/O transfer. If a particular host adapter has parity checking disabled, /DC all devices attached to it must have disconnects disabled, since parity is required during the reselection phase. Syntax: /DISCONNECT=n 6-8 DOS Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. Table 6.1 ASPI8XX Command Line Options (Cont.) Description Tells the host adapter to disable the SCSI bus data integrity checking feature known as parity. Some SCSI devices do not generate parity. Valid options are ON (check parity), which is the default value, or OFF (do not check parity). Syntax: /PARITY=n Option Name /PARITY or /P /EXCLUDE or /X Excludes support for an adapter that does not currently have BIOS support. Do not exclude an adapter that is supported (included) by the BIOS when booting the system. This option has three required parameters that identify the specific adapter you want to exclude: * * * PCI Device ID PCI Bus Number PCI Device/Function Number To obtain these parameters, boot the system using the /VERBOSE command line option (explained later). The monitor displays the parameters for the adapter or path you wish to exclude. Syntax: /EXCLUDE About the ASPI8XX.SYS Driver Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 6-9 Table 6.1 ASPI8XX Command Line Options (Cont.) Description Alters the SCSI ID for a host adapter (8-bit adapter where the SCSI IDs are [0:7]; 16-bit adapter where the SCSI IDs are [0:15]. It is suggested that IDs [8:15] not be used for your adapter). This option does not allow anyone to select a SCSI ID already in use. If the host adapter allows connection of both 8-bit and wide devices to the same bus, and the adapter number is changed to an ID greater than 7, then the 8-bit SCSI devices are not able to reselect the initiator. You are not allowed to change the SCSI ID of any adapter currently supported by the BIOS. Syntax: /HOST_ID=n Option Name /HOST_ID or ID /TIMEOUT or /T Uses a timeout mechanism to detect certain errors. When the driver issues a command to a SCSI device, a timer is started. If the timer expires before the command completes, the driver assumes something has gone wrong and takes steps to recover. If the device is BIOS controlled, the default for this option is 10 seconds. If the device is not BIOS controlled, the default is 0. Also, NVM settings can alter these defaults. The maximum setting is 0, which is no timeout. The range of allowable values is 0-65535 seconds. Syntax: /TIMEOUT=n 6-10 DOS Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. Table 6.1 ASPI8XX Command Line Options (Cont.) Description Causes more detailed information to appear on the monitor, after the ASPI8XX.SYS driver is initialized, during a system boot. For example, the following information may be displayed (all on one line) after using the /VERBOSE or /V option: 53C875 Rev 3 at PCI ID 15, Bus 0, Dev/Func 70h, CMD=0117h, SCRIPTS=FFFBE000h This option is useful when multiple adapters are present in the system, and the PCI Device ID, the PCI Bus number, and the PCI Device/Function number for each adapter needs to be known. This information is required to use the /EXCLUDE option already described in this section. Syntax: /VERBOSE To see more detailed adapter information displayed when you boot, the line in the CONFIG.SYS file that loads ASPI8XX.SYS should look like this: DEVICE=C:[PATH]ASPI8XX.SYS /VERBOSE Option Name /VERBOSE or /V 6.3.5 Troubleshooting Some potential problems and their suggested solutions are: System locks up at boot time. * * * Check for conflicts with other ASPI managers. Check for correct loading sequence in the CONFIG.SYS file. Reboot the system. The device driver does not recognize one of the nonboot SCSI peripherals (system may lock up). * * * * * * * Make sure the drivers were installed in the correct sequence. Make sure the drivers' entries in the CONFIG.SYS file have the correct path to the drivers. Power down all units in the system. Make sure all SCSI devices have unique ID numbers. Make sure both ends of the SCSI bus are terminated. Check all cable and power connections. Reboot the system. About the ASPI8XX.SYS Driver Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 6-11 6.4 About the SYMDISK.SYS Driver This section describes the characteristics of the SYMDISK.SYS driver and provides installation instructions. 6.4.1 Features The SYMDISK.SYS driver supports these features: * * * * * * * * * * Removable media devices Magneto Optical (MO) devices Non-512-byte sectors (1024, 2048, 4096) Multiple Logical Unit Numbers (LUN) OS/2 floppy format for MO and hard disks Multiple host adapters when adapter has not been controlled by the SCSI BIOS (no INT13h devices) Reserving drive letters for installed devices without media present in the device (see /UNITS under command line options) Adding drive letters Power management (to spindown drives) Allows up to eight host adapters 6.4.2 Description The SYMDISK.SYS driver allows you to connect drives with non-512-byte sectors, and to connect removable drives if you want to change the media. Use this driver also to obtain drive letters for devices (adapters) that are not supported by the BIOS. The SYMDISK.SYS driver communicates through ASPI8XX.SYS. To use the SYMDISK.SYS driver, you must also load ASPI8XX.SYS. 6-12 DOS Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 6.4.3 Installing the SYMDISK.SYS Driver To install the SYMDISK.SYS driver, follow these steps: Step 1. Copy the SYMDISK.SYS driver to the boot disk. The SDMS Software Device Drivers and Utilities CD-ROM contains the SYMDISK.SYS driver in this directory: {CD-ROM Drive Letter}:\DRIVERS\DOS The ASPI8XX.SYS driver is also required. Step 2. Add the lines shown below to the CONFIG.SYS file. List the drivers in this sequence: DEVICE=C:[PATH]ASPI8XX.SYS DEVICE=C:[PATH]SYMDISK.SYS 6.4.4 Using Command Line Options The SYMDISK.SYS device driver has several embedded functions that are accessed by using switches on the command line. Table 6.2 lists the command line options. No spaces are allowed in a single command line option, but spaces are required between different command line options. In the following descriptions, path refers to the adapter number (boot order designation), and id refers to the SCSI ID. The following conventions are also used: [] * | items in brackets are optional items in brackets followed by an * means repeat 0 or more times choose one of the given items About the SYMDISK.SYS Driver Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 6-13 Table 6.2 Option Name /ASK SYMDISK.SYS Command Line Options Description Prompts you at system bootup whether to load SYMDISK.SYS or not. To use this option, the line in the CONFIG.SYS file that loads SYMDISK.SYS should look like this: DEVICE=C:[PATH]SYMDISK.SYS /ASK /EXCLUDE Allows you to exclude a path:id:lun combination from being scanned or controlled by SYMDISK.SYS. The path parameter is mandatory with all ids and luns for that path excluded by default if just the path is specified. To use this option, the line in the CONFIG.SYS file that loads SYMDISK.SYS should look like this: DEVICE=C:[PATH]SYMDISK.SYS /EXCLUDE=path[:id[:lun]][,path[:id[:lun]]]* For example, if path 0, id 2, and lun 0 are designated, then the command line should look like this: DEVICE=C:[PATH]SYMDISK.SYS /EXCLUDE=0:2:0 Note: A limit of 24 path:id:lun combinations is allowed. 6-14 DOS Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. Table 6.2 Option Name /UNITS SYMDISK.SYS Command Line Options (Cont.) Description Allows the use of removable media, such as cartridge hard drives, each of which might have a different number of partitions. If media with more than one partition are used, set this option to the maximum number of partitions on any one media. LSI Logic recommends that you use this option when using removable media with more than one partition. To use this option, the line in the CONFIG.SYS file that loads SYMDISK.SYS should look like this (all on one line): DEVICE=C:[PATH]SYMDISK.SYS /UNITS=path:id:lun:num_units [,path:id:lun:num_units]* For example, if a removable media drive is at SCSI ID 2 on the first host adapter and you need to reserve three partitions, the command line should look like this: DEVICE=C:[PATH]SYMDISK.SYS /UNITS=0:2:0:3 When SYMDISK.SYS initializes, it defaults to either: One drive letter for a removable media device with no media present. -orThe number of partitions found on the media in the removable media device. The full path, id, lun, and num_units values are required for this option. Also, 24 devices is the standard limit of devices. /SSIZE Allows you to change the default sector size. The SYMDISK.SYS device driver defaults to the largest sector size found during boot, handling all different sector sizes found. In the case of removable media, SYMDISK.SYS assumes a 2048-byte sector size when no media is present. This option overcomes this limitation. To use this option, the line in the CONFIG.SYS file that loads SYMDISK.SYS should look like this: DEVICE=C:[PATH]SYMDISK.SYS /SSIZE=512|1024|2048|4096 For example, if a removable media drive is used that has a sector size of 2048-bytes, the command line should look like this: DEVICE=C:[PATH]SYMDISK.SYS /SSIZE=2048 If SYMDISK.SYS comes across a sector size larger than the one specified in this option, or if it finds a sector larger than the default, it refuses to read/write to that media. This driver reports an invalid media error to DOS. About the SYMDISK.SYS Driver Copyright (c) 1993-2001 by LSI Logic Corporation.

Description /SPINDOWN Use this power management feature to automatically spindown a disk when the disk is not accessed for a specified amount of time. The default spindown time is 15 minutes. You can specify a new spindown time in hours and minutes (hh:mm) with a minimum time of 1 minute. To use this option, the line in the CONFIG.SYS file that loads SYMDISK.SYS should look like this (all on one line): DEVICE=C:[PATH]SYMDISK.SYS /SPINDOWN=hh:mm 6.4.5 Troubleshooting Some potential problems and their suggested solutions are: The computer locks up and will not complete booting from a non-SCSI hard disk drive. Refer to the drive manufacturer's user manual. The computer locks up and will not complete booting from a SCSI hard disk drive. If the SCSI BIOS is seen during boot, a banner similar to the following appears: LSI Logic Corp.

You must load it in conjunction with the Microsoft CD-ROM Extension 2.21 or above (MSCDEX.EXE). The SYMCD.SYS driver communicates through ASPI8XX.SYS. To use the SYMCD.SYS driver, you must also load ASPI8XX.SYS. 6-18 DOS Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 6.5.3 Installing the SYMCD.SYS Driver To install the SYMCD.SYS driver, follow these steps: Step 1. Copy the SYMCD.SYS driver to the boot disk. The SDMS Software Device Drivers and Utilities CD-ROM contains the SYMCD.SYS driver in this directory: {CD-ROM Drive Letter}:\DRIVERS\DOS Step 2. Add SYMCD.SYS to the CONFIG.SYS file. It goes in after ASPI8XX.SYS and SYMDISK.SYS (if this driver is also being used), in this order: DEVICE=C:[PATH]ASPI8XX.SYS DEVICE=C:[PATH]SYMDISK.SYS DEVICE=C:[PATH]SYMCD.SYS /D:NAME Note: The /D: is not a drive letter designation; it indicates the name to be assigned to the CD-ROM. You must include the NAME, which can use any combination of up to eight characters. This is the same NAME to be used in conjunction with MSCDEX.EXE (see next page). Step 3. Add the MS-DOS LASTDRIVE command to the CONFIG.SYS file to ensure that sufficient drive letters are available to identify all devices connected to the SCSI bus: LASTDRIVE= About the SYMCD.SYS Driver Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 6-19 is in the CONFIG.SYS file, then: [PATH]MSCDEX /D:MY_CD should exist in the AUTOEXEC.BAT file. The /D: switches must match. Step 5. Check installation instructions for the CD-ROM drive itself for other parameters necessary to include with MSCDEX. When MSCDEX is loaded during the AUTOEXEC.BAT file execution, a message appears and shows the drive letter assignment to the CD-ROM drive. For example: DRIVE E = DRIVER MY_CD UNIT 0 This informs you that the CD-ROM drive is recognized and ready for use. 6.5.4 Using Command Line Options The SYMCD.SYS device driver has several embedded functions available that are accessed by using switches on the command line. Table 6.3 lists the command line options. No spaces are allowed in a single command line option, but spaces are required between different command line options. In the following descriptions, path refers to the adapter number (boot order designation). The following convention is also used: [] items in brackets are optional 6-20 DOS Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. Table 6.3 SYMCD.SYS Command Line Options Description Prompts you at initialization time whether to load SYMCD.SYS or not. For example, the line in the CONFIG.SYS file that loads SYMCD.SYS would look like this: DEVICE=C:[PATH]SYMCD.SYS /D:MY_CD /ASK Option Name /ASK /UPTOLUN Changes the default for multiple LUNs per Target ID on the SCSI bus. The current default is to scan all LUNs. CD-ROM changers that use multiple LUNs work by default. To turn off scanning all LUNs on a SCSI bus, choose /UPTOLUN=0. This saves some time during boot. /NOBCD Supports the Trantor Music Box CD audio application. Using this option prevents the track numbers from being converted to BCD (Binary Coded Decimal). If this option is used with CD audio applications such as Adaptec's cd-player, Corel's cd-audio, or Future Domain's cd-audio, track numbers >16 are not reported correctly because these applications require binary track numbers. For example, the line in the CONFIG.SYS file that loads SYMCD.SYS would look like this: DEVICE=C:[PATH]SYMCD.SYS /NOBCD 6.5.5 Troubleshooting Some potential problems and their suggested solutions are: The CD-ROM drive is not seen at boot time, or the system locks up. * * * * * * * Make sure the required drivers are installed and in the correct sequence. Make sure the drivers' entries in the CONFIG.SYS file have the correct path to the driver. Make sure MSCDEX.EXE, in the AUTOEXEC.BAT, has the same drive name as the CD-ROM driver in the CONFIG.SYS file. Make sure there is no ID or drive letter designation conflict. Power down all units in the system. Check the cable and power connections. Make sure the SCSI bus is properly terminated. About the SYMCD.SYS Driver Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 6-21 * Make sure sufficient drive letters are specified (through the MS-DOS lastdrive= command) to include the CD-ROM. A CD-ROM that uses multiple disks requires a letter for each disk. 6.5.6 Assigning Drive Letters This section provides important additional information for DOS users. Please note that the MS-DOS operating system assigns drive letters to primary partitions first. After the primary partitions have been assigned drive letters, the logical partitions are assigned drive letters. Do not assume that the drive letter designations will follow consecutively from device to device within a PC system. An Example: A system is configured with an IDE hard disk as the boot drive, a SCSI hard disk, and a CD-ROM drive. The IDE drive has three partitions: one primary and two logical. The SCSI hard disk has two partitions: one primary and one logical. The SCSI hard disk is assigned ID 1, and the CD-ROM is ID 4. The distribution of the drive letters is: A: B: C: D: E: F: G: H: 3 1/2" floppy drive 5 1/4" floppy drive IDE primary partition SCSI primary partition IDE first logical partition IDE second logical partition SCSI logical partition CD-ROM 6-22 DOS Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation.

It provides a friendly GUI, and help is available for any decision screen by pressing F1 or selecting Help in the window. Important: The ASPIFMT utility requires at least a VGA compatible monitor to display this utility. Additional DOS Utilities Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 6-23 To run this utility, three files are required: * * * ASPIFMT.EXE, ASPIINF.DAT, and ASPI8XX.SYS (you may use another ASPI manager). LSI Logic recommends that you place these files on a DOS bootable diskette, and run the executable file from this diskette rather than from a hard disk drive. This minimizes the possibility of interfering with the system. 6.6.1.3 Running the SDMS SCSI Low-Level Format Utility To run the SDMS Format Utility, follow these steps: Step 1. Create a DOS bootable diskette. Step 2. Add these DOS files to the diskette: Step 3. FDISK.EXE FORMAT.COM Since the hard drive remains unusable after a low-level format until you execute the DOS FDISK and FORMAT command procedures, the CONFIG.SYS file on this bootable diskette must also contain these DOS files. Step 4. Add the ASPI files from the SDMS Software Device Driver and Utilities CD-ROM and found in this directory: {CD-ROM DRIVE LETTER}: \UTILITY\DOS ASPIFMT.EXE ASPIINF.DAT Step 5. Run INSTALL.EXE to perform a default or custom installation of the SCSI DOS device drivers. Locate this program on the SDMS Software Device Driver and Utilities CD-ROM in this directory: {CD-ROM DRIVE LETTER}: \UTILITY\DOS Please note that SYMDISK.SYS is required only if you are formatting removable media drivers. ASPI8XX.SYS SYMDISK.SYS 6-24 DOS Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. Note: Refer to Section 6.2, "Using the DOS Installation Utility," page 6-3 for further details about creating these drivers. Step 6. Also create a CONFIG.SYS file to place on this bootable diskette with the single line: DEVICE=A:\ASPI8XX.SYS If you need SYMDISK.SYS, include this line: DEVICE=A:\SYMDISK.SYS Step 7. Boot from this diskette and at the DOS prompt type: ASPIFMT and press Enter. The recommended minimum memory requirement for this utility is 2 Mbytes. You need at least 500 Kbytes of conventional DOS memory, and the remainder in extended memory. When you run the format utility, it scans the SCSI bus for all hard disk and removable media drives. Then, it generates a display showing the devices found. You may select devices from this display for the utility to format. It can take from several minutes to several hours, depending on the size of the drive, to complete the format. If the format procedure is aborted for any reason, the drive remains unusable until an entire format cycle is completed. Caution: Use extreme caution when selecting a drive for formatting. The format process completely removes all information on a drive. Only 512-sector size is supported. Additional DOS Utilities Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 6-25 6.6.1.4 Troubleshooting Some potential problems and their suggested solutions are: Format does not complete and system is frozen. * * Check to see if the drive still has power. The only way to terminate the program is to reboot. If the format did not complete, the drive remains unusable until a low-level format is completed. The utility screens are unreadable. Check that your graphics card and your monitor match. For example, an SVGA card combined with a VGA monitor may not display the screens accurately. Older MO drives may give an "Unknown error" status code if the media is not present. This may cause the ASPIFMT to incorrectly identify the problem. If an unknown status code is received for an MO drive, check to see if the media are present. 6.6.2 Using the DOS Configuration Utility The SDMS Software Device Drivers and Utilities CD-ROM contains the DOS Configuration Utility (CONFIG.EXE) in this directory: {CD-ROM DRIVE LETTER}:\UTILITY\DOS 6.6.2.1 Features The configuration utility supports these features: * * * * Configures all DOS drivers Works for all LSI Logic LSI53C8XX PCI host adapters Provides a SCSI bus view showing all LSI53C8XX cards and attached peripherals Provides a GUI and online Help 6-26 DOS Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation.

All rights reserved. 6-29 {CD-ROM Drive Letter}:\DRIVERS\BIOS 6.6.4.1 Features The main feature supports host adapter selection for updating with a specific BIOS image. 6.6.4.2 Description This utility allows you to update the LSI Logic PCI SCSI BIOS on a host adapter based on a LSI53C815, LSI53C825, LSI53C825A, LSI53C875, LSI53C876, LSI53C885, LSI53C895, LSI53C895A, LSIC53C896, LSI53C1000, and LSI53C1010 SCSI chip. LSI Logic releases new versions of the SCSI BIOS periodically. Your host adapter must have a flash ROM on board to use this utility. You must place this utility on a DOS bootable diskette and execute it from this diskette. Do not run FLASH8X5 from a drive connected to the host adapter you are updating. Power down any hard disk drives attached to the host adapter that you are updating. Using DOS 5.0 or higher, create a bootable diskette by formatting it with the /s option (for example, format A:/s). Do not install any memory managers or SCSI drivers on the diskette. A minimum of 200 Kbytes of conventional memory is needed to execute the Flash Utility. Add the DOS mouse driver to AUTOEXEC.BAT for mouse control of the utility, if desired. Note: Some systems contain a specific PCI bus design, known as a Peer Bus implementation. This design provides an expanded PCI bus capacity by means of a secondary PCI bus. This implementation may cause issues with this Flash utility's ability to correctly identify LSI53C8XX or LSI53C1XXX boards installed on this secondary PCI bus. For example, an error could occur or the system could hang after executing this Flash utility. If your system contains a Peer Bus implementation, the only two alternatives available that will correct these issues are: Step 1. Reboot the computer. Step 2. Type FLASH8X5/q at the prompt to invoke an optional mode of identifying LSI53C8XX or 6-30 DOS Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved.

All rights reserved. 7-3 7.1.3 Description Although the LSI Logic SCSI controller's firmware can access the SCSI hard disk drives attached to the computer independently, the SCSI device drivers SYM8XX.ADD and SYM_HI.ADD act as an enhanced interface between the computer system and the SCSI BIOS firmware. Use of the device drivers increases the abilities of the SCSI controller firmware and fully utilizes the advancements and improvements of Pentium-based and higher microprocessors. The device drivers are also necessary to support the use of SCSI tape drives and CD-ROM drives with an OS/2 system. The SYM8XX.ADD and SYM_HI.ADD device drivers are compliant with the IBM OS/2 ADD (Adapter Device Driver) specification. Additionally, the device drivers work with third party applications that comply with the same specification. Both the SYM8XX.ADD and SYM_HI.ADD drivers allow up to eight host adapters to be present in your system. The first four host adapters are accessed in the order you specify using the SCSI BIOS Configuration Utility. Some members of the LSI Logic family of host adapters provide this utility. Refer to the PCI Storage Device Management System SDMS 4.0 User's Guide for the availability and use of the SCSI BIOS Configuration Utility. You can access the remaining host adapters based on their physical position in your system. Refer to your system documentation for further information. 7-4 OS/2 Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation.

All rights reserved. 7-5 * * Section 7.3.1, "Installing SYM8XX.ADD/SYM_HI.ADD During New System Installations," page 7-6 Section 7.3.2, "Updating SYM8XX.ADD/SYM_HI.ADD for Existing System Installations," page 7-7 Note: If you previously installed OS2CAM.ADD (a previous version of the SYM8XX.ADD driver), delete OS2CAM.ADD and the corresponding BASEDEV= statement in the CONFIG.SYS file after you complete the installation procedures. If you previously installed SYM8XX.ADD and/or SYM_HI.ADD in a directory other than \OS2\BOOT, move SYM8XX.ADD and/or SYM_HI.ADD to \OS2\BOOT, where the new versions of these drivers can replace the old versions. In both instances, the system will continue to boot using the previous drivers until these steps are taken. 7.3.1 Installing SYM8XX.ADD/SYM_HI.ADD During New System Installations Your system configuration determines which installation instructions are appropriate for you. If neither your boot drive nor SCSI CD-ROM is connected to an LSI Logic host adapter, install OS/2 and then add the drivers. Refer to the OS/2 Installation Guide for installing the operating system. Follow the steps in Section 7.3.2, "Updating SYM8XX.ADD/SYM_HI.ADD for Existing System Installations," page 7-7 to add the drivers. or If your boot drive or SCSI CD-ROM is attached to an LSI Logic host adapter, follow these steps: Step 1. Make copies of the diskettes used for installation that are included with the CD-ROM version of OS/2. Step 2. Determine the appropriate driver(s) for installation by locating the host adapter(s) to which the CD-ROM is attached in Section 7.1.2, "LSI Logic Devices Supported." Step 3. Copy the indicated driver(s) from the SDMS OS/2 driver diskette to the copy of Diskette 1. 7-6 OS/2 Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. In order to do so, you must delete files on Diskette 1 to provide space. Consult the README.1ST file on the Device Driver Pak. It contains a list of files that may not be deleted. Follow the instructions provided in the README.1ST file. Once space is made available on Diskette 1, copy the appropriate SDMS device driver onto this diskette. When ADD drivers are deleted from Diskette 1, make certain to delete or remark out the corresponding BASEDEV= statement in the CONFIG.SYS file. Otherwise, error messages will show up during installation. Step 4. Edit the CONFIG.SYS file on the copy of Diskette 1 by adding one of the following lines at the end of the file: BASEDEV=SYM8XX.ADD /V or BASEDEV=SYM_HI.ADD /V If installing both drivers, make sure that the BASEDEV= lines for the drivers appear in the CONFIG.SYS file in the order in which the drivers must load. Refer to Section 7.3.2.1, "Driver Order in the CONFIG.SYS File," page 7-8 to understand the importance of driver order. Step 5. Follow the directions in the README.1ST file for adding the following line to the CONFIG.SYS file: SET COPYFROMFLOPPY=1 This allows the SDMS driver to be copied from the installation diskette to the system's boot drive. Step 6. Place the copy of Installation Diskette in the A: drive and reboot the computer. Step 7. Proceed with the OS/2 installation process as documented in the OS/2 Installation Guide. 7.3.2 Updating SYM8XX.ADD/SYM_HI.ADD for Existing System Installations This section provides instructions for existing system installations. Apply these instructions when you have to: * Add drivers for newly installed LSI Logic host adapters, or Installing Drivers for OS/2 Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 7-7 * Update drivers for existing LSI Logic host adapters To add or update SDMS OS/2 drivers, follow these steps: Step 1. Open the System Setup folder located within the OS/2 System folder at the OS/2 Desktop. Step 2. Open the Install/Remove folder and then double click on the Device Driver Install icon. Step 3. Insert the diskette containing the SDMS device driver(s) in the source drive. The system will find all DDP files on the diskette and automatically install the corresponding drivers. Verify that the installation was successful by following steps 4 through 7. Step 4. Open the Utilities folder located within the Programs folder on the OS/2 Desktop. Step 5. Double click on the OS/2 System Editor to start the editor. Step 6. Open the CONFIG.SYS file in the root directory and find the line(s): BASEDEV=SYM8XX.ADD /V and/or BASEDEV=SYM_HI.ADD /V If installing both drivers, make sure that the BASEDEV= lines for the drivers appear in the CONFIG.SYS file in the order in which the drivers must load. Refer to the Section 7.3.2.1, "Driver Order in the CONFIG.SYS File," in this document to understand the importance of driver order. Step 7. Check the appropriate drivers are in the \OS2\BOOT directory on the boot drive. 7.3.2.1 Driver Order in the CONFIG.SYS File Because of the way OS/2 assigns drive letters, the order in which drivers appear in the CONFIG.SYS file is important. The drivers must appear in the order in which the drive letters are to be assigned. In particular: 7-8 OS/2 Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 1. OS/2 will install the BASEDEV= line at the beginning of the target system's CONFIG.SYS file regardless of where the line is located in that file on Diskette 1. You may need to rearrange the order in which drivers appear in the CONFIG.SYS file for the target system. 2. The driver for the host adapter to which the boot device is attached must appear before all other BASEDEV= drivers in the CONFIG.SYS file. 3. If you are installing both SDMS drivers and a host adapter containing the LSI53C895A chip, the driver that will control the host adapter will be the driver that appears first in the CONFIG.SYS file. If one of the two SDMS drivers is controlling the boot drive, that driver will also control the LSI53C895A chip, since it must appear first in order for the boot drive to be recognized. Refer to the OS/2 documentation to fully understand this requirement. 7.4 Using Command Line Options Your host adapter has a default configuration that consists of optimal values for operation. You may decide to alter these default values if there is a conflict between device settings or if you need to optimize system performance. Some values may be changed using the SCSI BIOS Configuration Utility provided with some members of the LSI Logic family of host adapters. Refer to your PCI Storage Device Management System SDMS 4.0 User's Guide for the availability and use of the SCSI BIOS Configuration Utility. In addition, the SDMS OS/2 device drivers have several embedded functions that can be accessed by using switches on the command line in the CONFIG.SYS file. Values are applied in the following order: * * * Manufacturer's settings SCSI BIOS Configuration Utility changes Command line options For the SYM8XX.ADD driver: When applying new values using the command line options, changes in synchronous and wide negotiations may only decrease speed or reduce width. Any changes that attempt to increase speed or width are ignored. Using Command Line Options Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 7-9 For the SYM_HI.ADD driver: When applying new values using the command line options, all changes in synchronous and wide negotiations are accepted. The options available using command line switches are described later. The SYM8XX.ADD driver is used in all examples; SYM_HI.ADD may be substituted for SYM8XX.ADD with identical results. The hba represents the logical number of a host adapter as displayed by the Verbose option in the column headed HBA. This is not the SCSI ID of the host adapter. Use an hba value with no :id following it to indicate all devices on an adapter. The id represents a SCSI target ID on the indicated adapter. To indicate all devices on a host adapter, do not use the SCSI ID of the host adapter for the id value. Instead, use the hba value as indicated in the preceding paragraph. The following conventions are also used: [] * indicates optional information indicates the pattern enclosed in the [ ] may be repeated 7-10 OS/2 Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation.

Description Sets the maximum synchronous transfer rate (in Mbyte transfers per second) to negotiate with a particular device. The allowable values for this setting are 0, 5, 10, 20, 40, and 80 Mbyte transfers per second, if the adapter is capable of the specified speed. All host adapters in the LSI Logic family support at least 10 Mbyte transfers per second; some support 20, 40, or 80 Mbyte transfers per second. To turn off synchronous transfers for a particular device, specify 0 (zero). The value set by this option only defines the maximum transfer rate negotiated. The actual rate also depends on the device's capability. The default value is the fastest transfer rate that is supported by a particular host adapter. Note: The maximum synchronous transfer rates effectively double when the adapter and device permit wide transfers (see the /WIDTH option). For example, a synchronous transfer rate setting of 40 Mbyte transfers per second actually produces a transfer rate of 80 Mbyte transfers per second if the adapter and device both allow and are set to perform wide transfers.

All rights reserved. 7-13 Table 7.1 OS/2 Command Line Options (Cont.) Description Sets the maximum synchronous offset to negotiate with a particular device. The allowable values for this setting are 0 to the maximum synchronous offset supported by the specified adapter. The LSI Logic controller chips support offsets up to 62. Refer to your host adapter user's guide for information on the maximum offset supported by your host adapter. If 0 (zero) is specified for the synchronous offset value, then synchronous transfers are turned off for any specified device. The value set by this option only defines the maximum offset that is negotiated. The resulting rate also depends on the device capability. The default value is the maximum offset that is supported by a particular host adapter. Syntax: /SYNCH_OFFSET = n Option Name /SYNCH_OFFSET or /SO /TIMEOUT or /T Sets a timeout value to detect certain errors. When the driver issues a command to a SCSI device, a timer is started. If the timer expires before the command completes, the driver assumes that something has gone wrong with the device, and takes steps to recover. The default value for this is 10 seconds. If you set the value to be less than the system has allocated for a particular device, your value is ignored. To turn off the timeout mechanism for a particular device, set the value to 0 (zero).

Description Allows (or does not allow) a device to disconnect during an I/O transfer. SCSI devices have the ability to disconnect from the bus during an I/O transfer. If a particular adapter has parity checking disabled, then you must use this option to disable disconnects for all devices on that adapter that do not generate parity. Refer to the /PARITY option for more information. Syntax: /DISCONNECT = n Option Name /DISCONNECT or /DC /PARITY or /P Allows enabling or disabling SCSI bus data integrity checking, known as parity. Use this option to disable parity checking. The LSI Logic chips are capable of enabling or disabling parity. Some non-SCSI compliant devices sold as SCSI devices do not generate parity. The LSI Logic chips always generate parity (for outputs), but may optionally check the parity (for inputs). Note: When disabling parity checking, you must disable disconnects for any device that does not generate parity, as the LSI Logic chips cannot disable parity checking for that device during the reselection phase. If a device does not generate parity and it disconnects, the I/O never completes. Refer to the /DISCONNECT option for more information about disabling disconnects for a device.

Check the cable connections and the host adapter installation. Verify that the adapter is not turned off in the SCSI BIOS Configuration Utility and that the adapter is not excluded using the /EXCLUDE command line option. The computer hangs or locks up when booting and the SCSI devices attached are not seen by the computer system. * Make sure that all the SCSI devices are configured at different ID numbers. If booting the system from a device on the SCSI bus, the boot drive must have the lowest ID or the highest ID. This depends on the scan order option selected in the SCSI BIOS Configuration Utility. Make sure both, but only, the ends of the SCSI bus are terminated. Make sure the device driver is listed in the CONFIG.SYS file and loads when the system boots. * * Troubleshooting Copyright (c) 1993-2001 by LSI Logic Corporation.

It provides installation instructions for new and existing system installations and includes these topics: * * * * Section 8.1, "Introduction," page 8-1 Section 8.2, "Building an SDMS 4.0 BTLD PCI Diskette," page 8-4 Section 8.3, "Installing the SDMS BTLD Driver," page 8-6 Section 8.4, "Troubleshooting," page 8-17 8.1 Introduction SCO OpenServer 5 is the first UNIX operating system licensed for IBM-compatible microcomputers. The integrated communications, file system, international application support, and documentation create an ideal platform for those requiring a full-featured, UNIX-based operating system. SCO OpenServer takes full advantage of the capabilities of the 80386 and above microprocessors. To connect SCSI devices to one or more host adapters, you must place the proper host adapter driver in the SCO OpenServer kernel. The SDMS Boot Time Loadable Driver (BTLD) diskette contains one package: slha contains the driver for SCO OpenServer 5 Releases You must link-edit the proper driver into the SCO OpenServer kernel. The kernel must reside on the boot drive: either an internal, non-SCSI hard drive (for example, IDE), or a SCSI hard drive attached to host adapter 0 with SCSI ID 0 and LUN 0. The BTLD permits an easy installation of the SCO OpenServer 5 operating systems with the software provided by The Santa Cruz Operation (SCO).

All rights reserved. 8-1 SCO OpenServer 5 provides only one installation diskette, which is labeled Boot Disk. This diskette and the SDMS BTLD driver diskette that you create along with other software media are used during a SCO OpenServer 5 installation. The slha driver allows SCO OpenServer 5 operating systems to interface with SCSI devices connected to the LSI Logic family of chipsets and/or LSI Logic host adapter cards. The current BTLD driver supports the Ultra160 LSI53C1000 and LSI53C1010 chipsets and Ultra160 host adapter boards. The following sections provide instructions for configuring the SCO OpenServer 5 kernel with the SDMS driver, installing SCO OpenServer 5 onto a hard drive, and adding SCSI peripheral devices. These instructions assume that you are familiar with UNIX system administration. Figure 8.1 illustrates the interface between the BTLD driver and the operating system.

The two possible installation procedures are: * * Installing UNIX and the proper SDMS BTLD driver for the first time on a SCSI boot drive. Loading or updating the proper SDMS BTLD driver on a boot drive. Read the important information below before beginning any installation procedure. * * * This driver supports all releases of SCO OpenServer 5 (Releases 5.0.2, 5.0.4, and 5.05). The diskette contains package slha, which is used for all SCO OpenServer 5 Releases. Within the text instructions for adding SCSI Disk Drives, Tape Drives, and CD-ROM drives, the system prompts you to check whether the driver is the default value or to enter the exact driver name. The package name and the driver name are slha. 8.2 Building an SDMS 4.0 BTLD PCI Diskette The SDMS Software Device Drivers and Utilities CD-ROM contains the sco.dd image file for SCO OpenServer operating systems in this directory: {UNIX CDROM path}/drivers/unixes/opnservr To create a BTLD driver diskette to use with SCO OpenServer installations, copy the raw dd image file onto a 1.44 Mbyte diskette.

Insert a formatted 3.5-inch (1.44 Mbyte) diskette into your A: floppy drive. Step 3. At the command prompt, type: fdimage -qv sco.dd A: Note: This command works when running MS-DOS, Windows 9x, Windows Me, Windows NT, or Windows 2000. If you are running antivirus software, LSI Logic recommends that you temporarily disable it when running the fdimage program. Otherwise, the fdimage program may not be able to get exclusive access to your floppy drive, which it requires to write the image to a diskette. Step 4. Label this diskette "BTLD Driver Diskette." Step 5. Use the BTLD driver diskette for SCO OpenServer 5 installations to: load the driver during the installation of the operating system, or access the devices on the SCSI bus after a SCO OpenServer 5 installation. You may also download the current SCO OpenServer 5 driver from the LSI Logic Web site at: http://www. lsilogic.com.After you are connected to this web site, place your cursor on the Get Drivers option in the menu bar. Click on the Drivers selection. Choose the SCO OpenServer 5 operating systems for SCSI and click on the Go button. Follow the instructions on subsequent screens to download the drivers. 8.3 Installing the SDMS BTLD Driver This section provides installation instructions for new and existing systems and solutions to potential problems that may be encountered. 8-6 SCO OpenServer 5 Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. To install the SDMS BTLD driver onto a new SCO OpenServer installation, follow the new system procedure. To install the SDMS BTLD driver on the non-SCSI boot drive, follow the existing system procedure. LSI Logic recommends that you complete either installation in one session. You should have sufficient time (possibly over an hour) available to complete this without interruption. 8.3.1 New System Installation This procedure installs SCO OpenServer onto a hard disk drive. This installation is necessary to build a new UNIX kernel that includes the SDMS BTLD driver. During installation, you are given the option of retaining current partitions on the root hard disk. For instance, a DOS partition or a user UNIX partition may already be established on the drive. For more details on UNIX installation, refer to the SCO OpenServer Handbook. You must link the SDMS BTLD driver into the UNIX kernel during installation. To install the BTLD driver, follow these steps: Step 1. Insert the SCO OpenServer 5 installation diskette and reboot the system. For all SCO OpenServer 5 releases, this diskette is labeled Boot Disk. Step 2. Type at the prompt: link Press Enter. Step 3. At the next prompt type: slha Do not remove the diskette and press Enter. The system prompts to insert the proper diskettes. Step 4. Insert either the proper installation diskette(s) or the SDMS BTLD driver diskette and press Enter. If the system prompts you to enter a routine: Please enter which routine (0-40) to replace '?' to list,'a' to add "slhainit" at the end [default], 'n' to do nothing, or 'q' to quit. Installing the SDMS BTLD Driver Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. 8-7 Enter the indicated routine number that precedes this message. Then the system may prompt with another inquiry: Please enter which routine (0-2) to replace '?' to list, `a' to add "slhapoll" at the end [default], 'n' to do nothing, or 'q' to quit. Step 5. Enter the indicated routine number that precedes this message. Step 6. Continue the installation according to the SCO OpenServer documentation. Step 7. To install SCSI device support, continue from Section 8.3.2.1, "Adding a SCSI Disk Drive," page 8-10 within the instructions for existing system installations. Note: The SCO OpenServer 5 operating system automatically creates a file unix.safe during installation. If you need to return to this initial UNIX kernel due to problems with subsequent installation procedures, type unix.safe at the boot prompt. 8.3.2 Existing System Installation This procedure assumes SCO OpenServer 5 is already installed on a hard disk drive. This installation is necessary to build a new UNIX kernel that includes the proper LSI Logic host adapter driver. The basic steps for accomplishing this task are outlined below. For more details on UNIX installation, refer to the SCO OpenServer System Administrator's Reference Manual. Follow this procedure to install the SDMS BTLD driver on the non-SCSI boot drive. Also, use this procedure to replace a previously installed SDMS driver on a SCSI drive. Some of the SCSI devices supported include tape drives, CD-ROM drives, and SCSI hard disk drives used as secondary storage. LSI Logic recommends that you complete the entire installation in one session. You should have sufficient time (possibly over an hour) available to complete this without interruption. Note: The SCO OpenServer system automatically creates a unix.safe file during installation. If you need to return to 8-8 SCO OpenServer 5 Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation.

Insert the SDMS BTLD diskette into the drive to install the SDMS driver and type: installpkg Press Enter. A system prompt appears to insert the requested diskette. Step 2. Press Enter. The system prompts you for the name of the package. Step 3. Type at the prompt: slha Press Enter to continue. If a driver is already present from a previous installation, a system prompt inquires about replacing it. Step 4. Reply y for yes. Step 5. Relink the kernel after the install package (installpkg) has completed by typing: /etc/conf/cf.d/link_unix at the command prompt. The system executes the command and then prompts for a response to: 1. Do you want this kernel to boot by default (y/n)? Type: y Press Enter. Then the system backs up the old kernel. 2. Do you want the kernel environment rebuilt (y/n)? Type: y Press Enter. Step 6. Reboot the system to activate the new kernel by typing at the command prompt: reboot Installing the SDMS BTLD Driver Copyright (c) 1993-2001 by LSI Logic Corporation.

To add a SCSI disk drive, type at the command prompt: mkdev hd Press Enter. The system prompts for the identifier of the host adapter that supports this device. Step 2. Press Enter if the default is correct. If it is incorrect, type: slha Press Enter. The system prompts for the host adapter that supports the disk drive. Step 3. Type the correct host adapter number and press Enter. If an additional LSI Logic host adapter is being added to the SCO OpenServer kernel, the system may prompt if you want to update the link-kit (add another host adapter). Type y and press Enter if you entered the host adapter number correctly: or Type n and press Enter if you entered the host adapter number incorrectly. The system then prompts for the host adapter identifier of the preceding step. The system prompts for the SCSI bus number of the disk drive. LSI Logic host adapters support one bus per adapter. Step 4. Press Enter to get the default bus number of zero or type zero (0) and press Enter. Note that dual channel devices appear as two host adapters. The system prompts for the Target ID of the disk drive. Step 5. Type the SCSI ID number of the disk drive and press Enter. 8-10 SCO OpenServer 5 Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. If the ID entered is in the range 8-15, a prompt requests verification that the device you are adding is a wide (16-bit) device, as only wide devices may have IDs greater than 7. Step 6. Type y and press Enter if the device is wide. or Type n and press Enter if an ID greater than 7 is incorrectly entered for a narrow (8-bit) device. The Target ID prompt is then reissued so you can enter the correct Target ID. The system prompts for the Logical Unit Number (LUN) of the disk drive. Step 7. Type the desired LUN and press Enter, or press Enter for the default value of zero. The system prompts you to update the SCSI Configuration file. Step 8. Type y and press Enter if the displayed values are correct. or Type n if the values are incorrect, and return to Section 8.3.2.1, "Adding a SCSI Disk Drive," page 8-10. A system prompt appears to create a new kernel. Step 9. Type y if you are adding only one device or this is the last device to be added. or Type n if additional devices are to be added later. Step 10.

You only need to link if you have a SCSI device attached to an LSI Logic host adapter. Follow the instructions in the SCO UNIX Installation documentation. Once the installation has completed, go to Step 1 in Section 8.3.2, "Existing System Installation," and use the installpkg to install your SDMS driver. A SCSI device is not found. * * * Reboot and press Ctrl-C to view the SCSI BIOS Configuration Utility. Verify the device is on the correct host adapter and ID. If the device is not shown, then it is probably turned off or a cabling problem exists. UNIX system behaves unreliably after a configuration change. Whenever the hardware or software configuration is altered, you must rebuild the kernel. Go to the directory /etc/conf/cf.d and type: ./link_unix to rebuild the kernel. An error message occurs during the rebuild of the kernel. * * Reinstall the proper SDMS driver using the installpkg utility. Remember to relink the kernel. Reboot the system.

To install other host adapter drivers, insert the host adapter diskette provided with the UnixWare 7 distribution package and press Enter. If there are no other host adapter drivers to install, continue the installation. Note: During the installation, if the driver does not find a hard disk on which to install the operating system, it aborts the process. The system loads the required drivers, such as C8XX, and indicates when they are loaded. At the end of the installation you will see a prompt to reinsert the driver diskette. Step 4. Insert the PCI SCSI SCO UnixWare driver diskette and press Enter. The kernel is rebuilt, and the system gets ready to boot from the SCSI disk drive. Step 5. Remove the PCI SCSI SCO UnixWare driver diskette when prompted to do so and reboot the system. 9.3.2 Existing System Installation This section provides instructions for adding or updating the C8XX package. 9.3.2.1 Adding or Updating the C8XX Package Before you install the C8XX driver, make a backup copy of the existing kernel: Step 1. Log on as root. Step 2. At the shell prompt, type: cp /stand/unix /stand/unix.safe 9-6 UnixWare 7 Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation. All rights reserved. Use this copy of the old kernel to reboot the system if the driver installation fails. Refer to Section 9.4, "Troubleshooting," for more information. Step 3. Insert the PCI SCSI SCO UnixWare driver diskette once the old kernel is saved. Step 4. Load the driver using the pkgadd command by typing: pkgadd -d diskette1 Step 5. Select C8XX and press Enter. The C8XX driver gets loaded on the system. The system prompts you again to load the driver even if loading was successful. Step 6. Type q (quit) and press Enter. Step 7. Verify that the driver is now loaded successfully by typing: pkginfo c8xx The package information should look like this: system c8xx Symbios IHV HBA After the C8XX package is loaded, a message may appear that indicates a system reboot is necessary. It sets a system flag to automatically rebuild the kernel upon the next system boot. Step 8. Reboot your system by typing the command: init 6 During the boot process, the driver scans the SCSI bus and lists the devices found on it. If the kernel panics during boot, then reboot the system with the saved copy of the old kernel. Booting from the saved copy of the kernel is described in the Section 9.4, "Troubleshooting," below. If the reboot is successful, the system is ready to use. Installing the C8XX Driver for Unixware Copyright (c) 1993-2001 by LSI Logic Corporation.

The official Linux kernel currently bundles three drivers that support the LSI Logic family of PCI SCSI chips: 53C7,8XX; NCR53C8XX; SYM53C8XX. The latter two drivers are based off the same code base and are maintained. LSI Logic recommends that you install the SYM53C8XX driver if your controllers are supported by it. If you are not sure, configure the kernel to load both the SYM53C8XX and NCR53C8XX drivers (either built into the kernel or as modules). The kernel will then select an appropriate driver for each of your LSI53C8XX or LSI53C1XXX controllers. The SYM53C8XX driver will install first and then the NCR53C8XX driver will install and support all remaining LSI53C8XX or LSI53C1XXX devices.

A list of these options is available below that include the default option along with a list of valid options. Each option has a description of when to use it, the syntax used, and any impact its use may have on the system. If you specify an option but the assignment is not valid, then the system uses the default value. To specify a value, place the option's characters on the load command line for the NWPA driver. For example, if the Wide SCSI Option on the command line option is desired, the load command line should look like this: load LSI8XXNW.HAM wide=off or Using the Command Line Options Copyright (c) 1993-2001 by LSI Logic Corporation.

The driver will not load with ? or h specified. Specify this option on the command line for a brief description of each of the options available in the driver, as well as valid values for each option. If you specify the ? or h option along with other options, the system invokes the Help screen and ignores the other options. In this case, the system does not load the driver. 12.4.2 NetWare NWPA Driver Customizable Options This section describes options that allow you to customize the driver for circumstances that may be unique to any system environment. Each command may be preceded by a "/" or "-" for backwards compatibility at the discretion of the user. The line options with multiple names are simply aliases for the same command. For example, to specify a SCSI bus host identification value, you could use one of these three aliases: * * * HostScsiId HostId Hid In this case, "hostscsiid", "hostid", and "hid" all specify the same option for the selection of the host adapter id. 12-10 NetWare Device Driver Installation Copyright (c) 1993-2001 by LSI Logic Corporation.
