detailed guidance for installing the LSIU40HVD, please follow the instructions in section 2.2, ?etailed installation procedure. for safe and proper installation, check the user s manual supplied with your computer and perform the following steps. step 1. ground yourself before removing the host adapter board. remove the LSIU40HVD from the packing and check that it is not damaged. an example of this board is shown in figure 2.1 . step 2. switch off and unplug the system. step 3. remove the cabinet cover on your computer to access the pci slots. 2-2 installing the LSIU40HVD caution: ground yourself by touching a metal surface before han- dling boards. static charges on your body can damage electronic components. handle plug-in boards by the edge. do not touch board components or gold connector con- tacts. the use of a static ground strap is recommended. step 4. locate the slots for pci plug-in board installation. refer to the user s manual for your computer to con?m the location of the pci slots. the LSIU40HVD requires a pci slot which allows bus master operation. see figure 2.2 . step 5. remove the blank panel on the back of the computer aligned with the pci slot you intend to use. save the bracket screw. step 6. carefully insert the edge connector j1 (see figure 2.1 ) of the host adapter into the pci slot. make sure the edge connector is properly aligned before pressing the board into place. see the example shown in figure 2.2 . note: you may notice that the components on a pci host adapter face the opposite way from those on other non-pci adapter boards you have in your system. this is correct, and the board is keyed to go in only one way. step 7. the bracket around the connectors j3 and j6 (see figure 2.1 ) should ? where the blank panel was removed. secure it with the bracket screw before making the internal and external scsi bus connections (see figure 2.2 ). step 8. if you are connecting any internal scsi devices, plug a 68-pin connector on the end of an internal scsi ribbon cable into connector j2 or j5 (see figure 2.1 ). make certain to match pin one on both connectors. chain the internal devices on this cable. step 9. connect your computer s led cable if desired. this is designed to drive the front panel led found on most pc cabinets to indicate activity on the scsi bus. step 10. replace the cabinet cover as described in the user s manual for your computer. step 11. make all external scsi bus connections. remember : the scsi bus requires proper termination, and no duplicate scsi ids. detailed installation procedure 2-3 step 12. finally, refer to the pci storage device management system sdms 4.0 user s guide (or the guide for the software that you will use) to load the driver software for your particular operating system. 2.2 detailed

scsi cables 2.2.3.1 making internal scsi bus connections this section provides step-by-step instructions about making internal scsi bus connections: step 1. if you are connecting an internal scsi device, plug the 68-pin connector on one end of a wide internal scsi ribbon cable into the connector j2, or j5 (see figure 2.4 ). scsi cables for internal connections scsi cable for external connections 68-pin high density 68-pin vhdci detailed installation procedure 2-9 figure 2.4 internal scsi ribbon cable to host adapter connection j5 j2 2-10 installing the LSIU40HVD step 2. plug the 68-pin connector on the other end of the internal scsi ribbon cable into the scsi connector on your internal scsi device. an example of this connection is shown in figure 2.5 . you must match pin 1 on all connections. figure 2.5 internal scsi ribbon cable to internal scsi device connection detailed installation procedure 2-11 step 3. additional internal scsi devices are plugged in by using an internal scsi ribbon cable with the required number of connectors attached along its length as shown in figure 2.6 . an example of this type of chained connection is shown in figure 2.7 . make sure to match pin 1 on all connections. figure 2.6 connecting additional internal scsi devices 2-12 installing the LSIU40HVD figure 2.7 multiple internal scsi devices chained together detailed installation procedure 2-13 step 4. most pc cabinets are designed with a front panel led which may already be connected to an existing ide drive. you may connect this led cable to your scsi host adapter, as shown in figure 2.8 . this connection causes the front panel led to indicate activity on the scsi bus. the led connectors j4 and j7 (see figure 2.1 ) are not keyed. the orientation of the led cable does not matter as long as all four pins are connected. figure 2.8 scsi led connectors some led cables have only two wires. in this case, place the connector on one end or the other of j4 or j7. if the led does not light during scsi bus activity from this host adapter, you may have to rotate the led cable 180 on j4 or j7. see table a.5 in appendix a for connector pinout information. j4 j7 2-14 installing the LSIU40HVD 2.2.3.2 making external scsi bus connections this section provides step-by-step instructions about making external scsi bus connections: step 1. to connect external scsi devices to the LSIU40HVD, plug the 68-pin vhdci connector on one end of a shielded external high density cable (see figure 2.3 ) into the host adapter connector j3 or j6 (see figure 2.1 ). this connector is now bracketed to the back panel of your computer. figure 2.9 shows how this connection is made. figure 2.9 external cable to host adapter detailed installation procedure 2-15 step 2. plug the 68-pin connector on the other end of the shielded external scsi cable into the scsi connector on the external scsi device. an example of this connection is shown in figure 2.10 . figure 2.10 external cable to external ssi device 2-16 installing the LSIU40HVD step 3. to connect more than one external scsi device to the host adapter, you must chain them together with shielded external scsi cables. an example of these chained connections is shown in figure 2.11 . figure 2.11 multiple external scsi devices chained together 2.2.4 scsi bus termination the devices making up the scsi bus are connected serially (chained together) with scsi cables. the ?st and last physical scsi devices connected on the ends of the scsi bus must have a set of resistors called terminators. all other scsi devices on the bus must have their terminators removed or disabled. detailed installation procedure 2-17 remember : the LSIU40HVD is also on the scsi bus; its termination is automatically enabled when it is connected to the end of the bus. differential peripheral devices are normally terminated with external terminators, but are sometimes set with jumpers or with a switch on the peripheral. refer to the peripheral manufacturer s instructions and to the user s manual for your computer for information on how to identify the terminator setting of each device and how to change it. caution: the auto-enable/disable sensing feature on the LSIU40HVD may enable termination erroneously if it is directly cabled to another scsi device or host adapter using the same sensing method. the LSIU40HVD senses scsi devices by detecting the ground signal on conductor 50 of a 68-conductor scsi cable. if you use an adapter to connect 8-bit devices externally with a 50-conductor scsi cable, the ground signal is detected on conductor 34. the LSIU40HVD automatically covers scsi bus termination for three different bus con?urations, depending on your use of the connectors on the LSIU40HVD (see figure 2.1 ). the three bus con?urations are: ? only for internal scsi connections ? only for external scsi connections ? for both internal and external scsi connections termination on the LSIU40HVD for these three different bus con?urations is discussed below. 2.2.4.1 internal scsi connections if internal scsi device connections to the host adapter have been made, you must terminate the last internal device on the scsi bus. you must disable the termination on all other devices. termination on the host adapter is automatically enabled in this case. figure 2.12 shows an example of how termination is determined for this scsi bus con?uration. 2-18 installing the LSIU40HVD figure 2.12 internal scsi device termination 2.2.4.2 external scsi connections if external scsi device connections to the host adapter have been made, you must terminate the last external device on the scsi bus. you must disable the termination on all other devices. termination on the host adapter is automatically enabled in this case. figure 2.13 shows an example of how termination is determined for this scsi bus con?uration on the LSIU40HVD channel b. detailed installation procedure 2-19 figure 2.13 external scsi device termination 2.2.4.3 internal and external scsi connections if internal and external scsi device connections to the host adapter have been made, you must terminate the last internal and external devices on the scsi bus. you must disable the termination on all other devices. termination on the host adapter is automatically disabled in this case. figure 2.14 shows an example of how termination is determined for this scsi bus con?uration on the LSIU40HVD channel b. last device on chain - termination enabled does not end chain - termination disabled host adapter automatically terminated 2-20 installing the LSIU40HVD figure 2.14 internal and external scsi device termination last device on chain - termination enabled does not end chain - termination disabled last device on chain - termination enabled host adapter termination automatically disabled detailed installation procedure 2-21 2.2.4.4 internal scsi connections for both internal connectors if internal scsi device connection to another LSIU40HVD has been made, or any connection to a device that uses the same sensing method for automatic termination as your LSIU40HVD, you must properly set the termination override jumpers tp2, tp3, tp5, or tp6 (see figure a.1 ). when connecting another LSIU40HVD, or other device that uses the same termination sensing scheme, you must connect the jumper to both pins on the tp for the connector used. for example, if another LSIU40HVD is attached to j3, place the jumper on both stake pins of tp3. 2.2.5 setting scsi ids you must set each scsi device and the host adapter to a separate scsi id, 0 through 15. scsi id 7 is the preset host adapter setting, giving it the highest priority on the scsi bus. if you plan to boot your computer from a scsi hard disk drive on the scsi bus, that drive should have scsi id 0, or the lowest scsi id on the bus. chapter 3, ?on?uring the LSIU40HVD, explains how to set your host adapter id using the lsi logic scsi bios con?uration utility. the peripheral device scsi ids are usually set with jumpers or with a switch on the peripheral. refer to the peripheral manufacturer s instructions and to the user s manual for your computer to determine the id of each device and how to change it. you must have no duplication of scsi ids on a scsi bus. step 1. determine the scsi id of each device on the scsi bus. note any duplications. step 2. make any necessary changes to the scsi ids and record the ids for future reference. table 2.2 is provided as a place to keep this record. 2-22 installing the LSIU40HVD 2.3 setting interrupts normally, you do not change the default interrupt routing for the LSIU40HVD, since performance is usually increased by having two separate interrupts. however, if your system does

?hen to con?ure the LSIU40HVD, page 3-1 ? section 3.2, ?tarting the scsi bios con?uration utility, page 3-2 ? section 3.3, ?xiting the scsi bios con?uration utility, page 3-14 3.1 when to con?ure the LSIU40HVD in most cases, changing the default con?uration of the host adapter is not necessary. if a con?ct does exist between device settings, or if a need exists to optimize system performance, this con?uration utility provides the means to change system con?urations. the con?uration settings that may be changed are discussed in table 3.1 . the global settings affect the host adapter and all scsi devices which are connected to it. the device settings affect only individual scsi devices. table 3.1 global default settings settings for the host adapter and all devices default settings scam

utility if you have scsi bios version 4.0 and later, and it includes the lsi logic scsi bios con?uration utility, the default con?uration of the scsi host adapter(s) can be changed. if a con?ct does exist between device settings or if optimizing system performance is necessary, then use this con?uration utility. the version number of the scsi bios appears in a banner displayed on your computer monitor during boot. if the con?uration 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 ?e seconds, giving you time to start the utility. if you decide to press control 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 lsi logic scsi bios con?uration utility. nvram is available on this lsi logic LSIU40HVD. changes can be made and stored to nvram using this

powerful tool. if, while using it, you somehow disable all of your controllers, pressing control a (or control e on version 4.04 or later) after memory initialization during reboot allows you to re-enable and recon?ure. not all devices detected by the con?uration utility can be controlled by the bios. devices such as tape drives and scanners require that a device driver speci? to that peripheral be loaded. the device manufacturer provides the device drivers. 3.2.1 con?uration utility main menu when you start the lsi logic scsi bios con?uration utility, the main menu appears. this menu displays a list of up to four lsi logic pci to scsi host adapters in your system and information about each of them. the LSIU40HVD appears on the menu as two lsi53c875 entries; one for each channel. to select an adapter, use only the arrow keys and the enter key. then, you can view and/or change the current settings for that adapter and the scsi devices attached to it. you can select an adapter only if current status is on . changes are possible only if nvram is present on your adapter. figure 3.1 is an example of the main menu. 3-4 con?uring the LSIU40HVD figure 3.1 main menu below the list of host adapters on the main menu display, you see eight options. they are described in detail below. if these settings are altered, the system will reboot after the quit option is selected, which allows the user to exit from the con?uration utility. 3.2.1.1 change adapter status the change adapter status allows the user to activate or deactivate a host adapter and all scsi devices attached to it. when this option is used to make a change, the change takes place after a reboot upon exit from the utility. figure 3.2 is an example of the change status on next boot menu. main menu

adapter setup menu when you select adapter setup , the corresponding menu appears. figure 3.6 is an example of the adapter setup menu. figure 3.6 adapter setup menu the settings in this menu are global settings that affect the selected host adapter and all scsi devices attached to it. one of these choices can be selected by highlighting it and pressing enter . scam support the lsi logic bios version 4.0 and above supports the scsi plug and play protocol called scam (scsi con?ured automatically). scam support by default is off in versions 4.09 and later for the lsi53c876 device. the user may choose to turn this on only if the system drivers do not require scam off. note that if this bios is ?shed onto a board with existing settings, then these settings will not be changed to re?ct the new bios defaults. go into the con?uration utility to change these settings. parity the lsi logic pci to scsi host adapters always generate parity, but some older scsi devices do not. therefore, you are offered the option of disabling parity checking. adapter setup scam support off parity enabled host scsi id 7 scan order low to high <0..max> removable media support none chs mapping scsi plug & play mapping spinup delay 2 help restore default setup exit this menu starting the scsi bios con?uration utility 3-9 note: when disabling parity checking, it is also necessary to 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 this option refers to the host adapter s scsi id, which is a unique number used to identify the device on the scsi bus. note: in general, the user should not change the host adapter id from the default value of 7, as this gives it the highest priority on the scsi bus. please also note that if you have 8-bit scsi devices (narrow), they cannot see host ids greater than 7. scan order this option allows the user to tell the scsi bios and device drivers to scan the scsi bus from low to high (0 to max) scsi id, or from high to low (max to 0) scsi id. if there is more than one device on the scsi bus, changing the scan order changes the order in which drive letters are assigned by the system. drive order may be reassigned differently in systems supporting the bios boot speci?ation (bbs). see chapter 2, ?csi bios, in the pci storage device management system sdms 4.0 user s guide for additional information regarding bbs. note: this scan order option may con?ct with operating systems that automatically assign a drive order. removable media support this option de?es the removable media support for a speci? drive. when this option is selected, a window appears with three choices: ? none ? boot drive only ? with media installed none indicates there is no removable media support whether the drive is selected in bbs as being ?st, or ?st in scan order in non-bbs. boot drive only provides removable media support for a removable hard drive if it is ?st in the scan order. 3-10 con?uring the LSIU40HVD with media installed provides removable media support wherever the drive(s) actually resides. one of these choices can be selected by highlighting it and pressing enter. chs mapping this option de?es the cylinder head sector (chs) values that will be mapped onto a disk without pre-existing partition information. scsi plug and play mapping is the default value. to support interchange with noncompatible systems, there is another option that can be selected by choosing chs mapping and then cursoring to alternate chs mapping . note: neither of these options will have any effect after the disk has been partitioned with the fdisk command. to remove partitioning, two options are available: ? reformat the disk using the format device option. see section 3.2.2.2, ?evice selections menu. ? use the fdisk /mbr command at the c:\ prompt, where mbr represents master boot record. impor tant: reformatting the disk or using fdisk /mbr erases all partitioning and data that exists. be careful that you target the correct disk when using either the format utility or the fdisk /mbr command. note: after clearing the partitions and data, it is necessary to reboot and clear memory or the old partitioning data will be reused, thus nullifying the previous operation. spinup delay (seconds) this option allows the user to stagger spinups for a longer period of time to balance the total current load. the default value is 2 seconds with choices between 1 and 10 seconds. this is a power management device designed to accommodate disk devices that may have heavy current load during power-up. if multiple drives are being powered up simultaneously and drawing heavy current loads, then this option staggers the spinups to limit start-up current. starting the scsi bios con?uration utility 3-11 3.2.2.2 device selections menu when you select the device selections option, the corresponding menu (as shown in figure 3.7 ) appears. figure 3.7 device selections menu the settings in this menu affect individual scsi devices attached to the selected host adapter. changes made from this menu do not cause the system to reboot upon exit from the scsi bios con?uration utility. to change a value, select the required device by using the arrow keys and press enter. a new menu (as shown in figure 3.8 ) appears providing the options and utilities available. device selections 0-7 sync data disc time scan queue initial rate width out bus

of this menu: figure 3.8 device selections menu (cont.) please review the descriptions of each option below before changing any values. sync rate (mbytes/sec) this option de?es the maximum data transfer rate the host adapter will attempt to negotiate. the host adapter and a scsi device must agree to a rate they can both handle. width (bits) this option de?es 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 chips that can do 16-bit data transfers have this option enabled. disconnect scsi devices have the ability to disconnect from the initiator during an i/o transfer. this disconnect option frees the scsi bus to allow other i/o processes. additionally, it tells the host adapter whether or not to allow a device to disconnect. some devices run faster with disconnects enabled (mostly newer devices), while some run faster with disconnects disabled (mostly older devices).

menu starting the scsi bios con?uration utility 3-13 read write i/o time-out (seconds) this option 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. because this provides a safeguard by allowing the system to recover if an i/o operation fails, you should always set the time-out to a value greater than zero. note: a zero value allows unlimited time for an operation to complete and could result in the system being hung-up. scan for device at boot time 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. scan for scsi logical units (luns) set this option to no if problems arise with a device that responds to all luns whether they are occupied or not. for example, if a scsi device with multiple luns is present on the 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 only. queue tags if the device driver has the capability, this option allows the user to enable or disable the issuing of queue tags during i/o requests. initial boot this option allows any device attached to the ?st adapter to become the boot device. it provides the users of non-bbs personal computers with some of the ?xibility of a bbs machine. format device if enabled, this option allows the user to low-level format a magnetic disk drive. low-level formatting will completely and irreversibly erase all data on the drive. formatting will default the drive to a 512-byte sector size even if the drive had previously been formatted to another sector size. verify this option allows the user to read all the sectors on a disk looking for errors. when selected, this option displays the following message: ?erify all sectors on the device press esc to abort else press any key to continue 3-14 con?uring the LSIU40HVD help this option brings up a help screen with information about the device selections menu. restore default setup this option resets all device selections back to their default settings. select this option to restore all manufacturing defaults for the speci?d adapter. note that all user-customized options will be lost upon saving after restoring default setup. exit this menu this option allows the user to leave the device selections menu and return to the previous screen. 3.3 exiting the scsi bios con?uration utility because some changes only take effect after the system reboots, it is important that the user exit from this con?uration utility properly. return to the main menu and exit by using the quit option. impor tant: rebooting the system without properly exiting from this utility may cause some changes to not take effect.
