INSTALLTION GUIDE
1) Setting Method
c e Make sure your computer is turned off before you open the case. Plug the carefully into the 40pin IDE slot on your computer. Caution: Make sure to align pin1 on host adapter interface connector with pin 1 on your Flash Disk Module. Pin 1 is indicated by a triangle on the Flash Disk Module connector. e e The Flash Disk Module is used power connector cable of the computer. Caution: If you need to remove your Flash Disk Module, use both hands to pull it out carefully. Check all cable connections and then replace your computer cover. Before you format or partition your new drive, you must configure your computer's BIOS so that the computer can recognize your new drive. c Turn your computer on. As your computer start up, watch the screen for a message describing how to run the system setup program on the screen (sometimes called BIOS or CMOS setup). This is usually done by pressing a special key, such as Delete, Esc or F1 during startup. See your computer manual for details. Press the appropriate key to run the system setup program. If your BIOS provides automatic drive detection (an "AUTO" drive type), select this option. ( We recommend to use Normal / CHS mode to partition your Flash Disk Module to get the maximum formatted capacity. ) This allows your computer to configure itself automatically for your new drive. If your BIOS dose not provide "AUTO" drive detection, select "User-defined" drive setting and enter the CHS values from the table. BIOS Settings (see specification) Capacity Cylinders Heads Sectors(unformatted) Save the settings and exit the System Setup program. ( your computer will automatically reboot ) After you configure your computer, you can use the standard DOS commands to partition and format your Flash Disk Module, as described below. To partition your new Flash Disk Module with Microsoft DOS program : c e Insert a bootable DOS diskette into your diskette drive and restart your computer. Insert a DOS program diskette that contains the FDISK.EXE and FORMAT.COM programs into your diskette drive. Use the same DOS version that is on your bootable diskette. At the A:\ > prompt, type "FDISK" and press Enter. Select "Create DOS partition or logical DOS drive" by pressing 1. Then press Enter. Select "Create primary DOS partition" by pressing 1 again. Then press Enter. Create your first drive partition. If you are creating a partition that will be used to boot your computer (drive C), make sure that the partition is marked active. e i i i Create an extended partition and additional logical drives as necessary, until all the space on your new hard drive has been partitioned. When the partitioning is complete, FDISK reboots your computer. Caution: Make sure to use the correct drive letters so that you do not format a drive that already contains data. At the A:\ > prompt, type "format c:/s", where c is the letter of your first new partition, Repeat the format process for all the new partitions you have created. After you format your drive, it is ready to use.

HFDOM40KVXXX
In True IDE Mode only A[2:0] are used to select the one of eight registers in the Task File, the remaining address lines should be grounded by the host. This input / output is the Pass Diagnostic signal in the Master / Slave handshake protocol. In the True IDE Mode, this input/output is the Disk Active/Slave Present signal in the Master/Slave handshake protocol. CS0 is the chip select for the task file registers while CS2 is used to select the Alternate Status Register and the Device Control Register. All Task File operations occur in byte mode on the low order bus D00-D07 while all data transfers are 16 bit using D00-D15.
This is an I/O Read strobe generated by the host. The I/O Write strobe pulse is used to clock I/O data on the Card Data bus into the Storage Card controller registers when the Storage Card is configured to use the I/O interface. The clocking will occur on the negative to positive edge of the signal (trailing edge). In True IDE Mode signal is the active high Interrupt Request to the host. This input pin is the active low hardware reset from the host. This output signal may be used as IORDY. This output signal is asserted low when this device is expecting a word data transfer cycle.

REGISTERS
HFDOM40KVXXX
1) Data Register (Address - 1F0h[170h];Offset 0,8,9) The Data Register is a 16-bit register, and it is used to transfer data blocks between the CompactFlash Storage Card data buffer and the Host. This register overlaps the Error Register.The table below describes the combinations of data register access and is provided to assist in understanding the overlapped Data Register and Error/Feature Register rather than to attempt to define general PCMCIA word and byte access modes and operations. See the PCMCIA PC Card Standard Release 2.0 for definitions of the Card Accessing Modes for I/O and Memory cycles. Note: Because of the overlapped registers, access to the 1F1h, 171h or offset 1 are not defined for word (-CE2 = 0 and -CE1 = 0) operations. These accesses are treated as accesses to the Word Data Register. The duplicated registers at offsets 8, 9 and Dh have no restrictions on the operations that can be performed by the socket. Data Register Access DATA Register Word Data Register Even Data Register Odd Data Register Odd Data Register Error/Feature Register Error/Feature Register Error/Feature Register CE20 1 1 0 1 0 0 CE10 0 0 1 0 1 0 A0 X 0 1 X 1 X X Offset 0,8,9 0,8 9 8,9 1,Dh 1 Dh Data Bus D15-D0 D7-D0 D7-D0 D15-D8 D7-D0 D15-D8 D15-D8
2) Error Register (Address - 1F1h[171h];Offset 1,0Dh Read Only) This register contains additional information about the source of an error when an error is indicated in bit 0 of the Status register. The bits are defined as follows: D7 BBK D6 UNC D5 0 D4 IDNF D3 0 D2 ABRT D1 0 D0 AMNF
Error Register This register is also accessed on data bits D15-D8 during a write operation to offset 0 with -CE2 low and -CE1 high. Bit 7 (BBK): this bit is set when a Bad Block is detected. Bit 6 (UNC): this bit is set when an Uncorrectable Error is encountered. Bit 5: this bit is 0. Bit 4 (IDNF): the requested sector ID is not valid error or cannot be found. Bit 3: this bit is 0. Bit 2 (Abort) This bit is set if the command has been aborted because of a CompactFlash Storage Card status condition: (Not Ready, Write Fault, etc.) or when an invalid command has been issued. Bit 1 This bit is 0. Bit 0 (AMNF) This bit is set in case of a general error happened. 3) Feature Register(Address - 1F1h[171h];Offset 1,0Dh Writer Only) This register provides information regarding features of the CompactFlash Storage Card that the host can utilize. This register is also accessed on data bits D15-D8 during a write operation to Offset 0 with -CE2 low and -CE1 high. BIT DESCRIPTION7 6 5 4 3 2 1 0

D0 ERR
Status & Alternate Status Register Bit 7 (BUSY): the busy bit is set when the CompactFlash Storage Card has access to the command buffer and registers and the host is locked out from accessing the command register and buffer. No other bits in this register are valid when this bit is set to a 1. Bit 6 (DRDY): DRDY indicates whether the device is capable of performing CompactFlash Storage Card operations. This bit is cleared at power up and remains cleared until the CompactFlash Storage Card is ready to accept a command. Bit 5 (DWF): This bit, if set, indicates a write fault has occurred. Bit 4 (DSC): This bit is set when the CompactFlash Storage Card is ready. Bit 3 (DRQ): The Data Request is set when the CompactFlash Storage Card requires the information to be transferred either to or from the host through the Data register. Bit 2 (CORR): This bit is set when a Correctable data error has been encountered and the data has been corrected. This condition does not terminate a multi-sector read operation. Bit 1 (IDX): This bit is always set to 0. Bit 0 (ERR): This bit is set when the previous command has ended in some type of error. The bits in the Error register contain additional information describing the error. It is recommended that media access commands (such as Read Sectors and Write Sectors) that end with an error condition should have the address of the first sector in error in the command block registers.
9) Device Control Register( Address - 3F6h[376h]; Offset Eh) This register is used to control the CompactFlash Storage Card interrupt request and to issue an ATA soft reset to the card. This register can be written even if the device is BUSY. The bits are defined as follows:
D& X
D6 X
D5 X
D4 X
D3 1
D2 SW Rst
D1 -IEn
D0 0
Device Control Register Bit 7: this bit is an X (don't care). Bit 6: this bit is an X (don't care). Bit 5: this bit is an X (don't care). Bit 4: this bit is an X (don't care). Bit 3: this bit is ignored by the CompactFlash Storage Card. Bit 2 (SW Rst): this bit is set to 1 in order to force the CompactFlash Storage Card to perform an AT Disk controller Soft Reset operation. This does not change the PCMCIA Card Configuration Registers (4.3.2 to 4.3.5) as a hardware Reset does. The Card remains in Reset until this bit is reset to `0.' Bit 1 (-IEn): the Interrupt Enable bit enables interrupts when the bit is 0. When the bit is 1, The interrupts from the CompactFlash Storage Card are disabled. This bit also controls the Int bit in the Configuration and Status Register. This bit is set to 0 at power on and Reset. Bit 0: this bit is ignored by the CompactFlash Storage Card. 10) Card (Drive) Address Register(Address 3F7h[377h]; Offset Fh) This register is provided for compatibility with the AT disk drive interface. It is recommended that this register not be mapped into the host's I/O space because of potential conflicts on Bit 7. The bits are defined as follows:
D7 X
D6 -WTG
D5 -HS3
D4 -HS2
D3 -HS1
D2 -HS0
D1 -nDS1
D0 -nDS0

Implementation Note: Conflicts may occur on the host data bus when this bit is provided by a Floppy Disk Controller operating at the same addresses as the CompactFlash Storage Card. Following are some possible solutions to this problem for the PCMCIA implementation: 1) Locate the CompactFlash Storage Card at a non-conflicting address, i.e. Secondary address (377) or in an independently decoded Address Space when a Floppy Disk Controller is located at the Primary addresses. 2) Do not install a Floppy and a CompactFlash Storage Card in the system at the same time. 3) Implement a socket adapter, which can be programmed to (conditionally) tri-state D7 of I/0 address 3F7h/377h when a Compact Flash Storage Card is installed and conversely to tri-state D6-D0 of I/O address 3F7h/377h when a floppy controller is installed. 4) Do not use the CompactFlash Storage Card's Drive Address register. This may be accomplished by either a) If possible, program the host adapter to enable only I/O addresses 1F0h-1F7h, 3F6h (or 170h-177h, 176h) to the CompactFlash Storage Card or b) if provided use an additional Primary / Secondary configuration in the CompactFlash Storage Card which does not respond to accesses to I/O locations 3F7h and 377h. With either of these implementations, the host software must not attempt to use information in the Drive Address Register. Bit 6 (-WTG): this bit is 0 when a write operation is in progress, otherwise, it is 1. Bit 5 (-HS3): this bit is the negation of bit 3 in the Drive/Head register. Bit 4 (-HS2): this bit is the negation of bit 2 in the Drive/Head register. Bit 3 (-HS1): this bit is the negation of bit 1 in the Drive/Head register. Bit 2 (-HS0): this bit is the negation of bit 0 in the Drive/Head register. Bit 1 (-nDS1): this bit is 0 when drive 1 is active and selected. Bit 0 (-nDS0): this bit is 0 when the drive 0 is active and selected.

This command performs the internal diagnostic tests implemented by the CompactFlash Storage Card. If in PCMCIA configuration this command runs only on the CompactFlash Storage Card which is addressed by the Drive/Head register when the diagnostic command is issued. This is because PCMCIA card interface does not allows for direct inter-drive communication (such as the ATA PDIAG and DASP signals). If in True IDE Mode the Drive bit is ignored and the diagnostic command is executed by both the Master and the Slave with the Master responding with status for both devices. The Diagnostic codes shown in Table 39 are returned in the Error Register at the end of the command.

This command writes the desired head and cylinder of the selected drive with a vendor unique data pattern (typically FFh or 00h). To remain host backward compatible, the CompactFlash Storage Card expects a sector buffer of data from the host to follow the command with the same protocol as the Write Sector(s) command although the information in the buffer is not used by the CompactFlash Storage Card. If LBA=1 then the number of sectors to format is taken from the SecCnt register (0=256). The use of this command is not recommended.

The Read Multiple command performs similarly to the Read Sectors command. Interrupts are not generated on every sector, but on the transfer of a block which contains the number of sectors defined by a Set Multiple command. Command execution is identical to the Read Sectors operation except that the number of sectors defined by a Set Multiple command are transferred without intervening interrupts. DRQ qualification of the transfer is required only at the start of the data block, not on each sector. The block count of sectors to be transferred without intervening interrupts is programmed by the Set Multiple Mode command, which must be executed prior to the Read Multiple command. When the Read Multiple command is issued, the Sector Count Register contains the number of sectors (not the number of blocks or the block count) requested. If the number of requested sectors is not evenly divisible by the block count, as many full blocks as possible are transferred, followed by a final, partial block transfer. The partial block transfer is for n sectors, where n = remainder (sector count / block count). If the Read Multiple command is attempted before the Set Multiple Mode command has been executed or when Read Multiple commands are disabled, the Read Multiple operation is rejected with an Aborted Command error. Disk errors encountered during Read Multiple commands are posted at the beginning of the block or partial block transfer, but DRQ is still set and the data transfer will take place as it normally would, including transfer of corrupted data, if any Interrupts are generated when DRQ is set at the beginning of each block or partial block. The error reporting is the same as that on a Read Sector(s) Command. This command reads from 1 to 256 sectors as specified in the Sector Count register. A sector count of 0 requests 256 sectors.The transfer begins at the sector specified in the Sector Number Register. At command completion, the Command Block Registers contain the cylinder, head and sector number of the last sector read. If an error occurs, the read terminates at the sector where the error occurred. The Command Block Registers contain the cylinder, head and sector number of the sector where the error occurred. The flawed data is pending in the sector buffer. Subsequent blocks or partial blocks are transferred only if the error was a correctable data error. All other errors cause the command to stop after transfer of the block which contained the error.

The Read Long command performs similarly to the Read Sector(s) command except that it returns 516 bytes of data instead of 512 bytes. During a Read Long command, the CompactFlash Storage Card does not check the ECC bytes to determine if there has been a data error. Only single sector read long operations are supported. The transfer consists of 512 bytes of data transferred in word mode followed by 4 bytes of ECC data transferred in byte mode. This command has the same protocol as the Read Sector(s) command. Use of this command is not recommended.

This command reads from 1 to 256 sectors as specified in the Sector Count register. A sector count of 0 requests 256 sectors. The transfer begins at the sector specified in the Sector Number Register. When this command is issued and after each sector of data (except the last one) has been read by the host, the CompactFlash Storage Card sets BSY, puts the sector of data in the buffer, sets DRQ, clears BSY, and generates an interrupt. The host then reads the 512 bytes of data from the buffer. At command completion, the Command Block Registers contain the cylinder, head and sector number of the last sector read. If an error occurs, the read terminates at the sector where the error occurred. The Command Block Registers contain the cylinder, head, and sector number of the sector where the error occurred.

When the requested sectors have been verified, the CompactFlash Storage Card clears BSY and generates an interrupt. Upon command completion, the Command Block Registers contain the cylinder, head, and sector number of the last sector verified. If an error occurs, the verify terminates at the sector where the error occurs. The Command Block Registers contain the cylinder, head and sector number of the sector where the error occurred.

Features 01h and 81h are used to enable and clear 8 bit data transfer modes in True IDE Mode. If the 01h feature command is issued all data transfers will occur on the low order D7D0 data bus and the IOIS16 signal will not be asserted for data register accesses. Features 0Ah and 8Ah are used to enable and disable Power Level 1 commands. Feature 0Ah is the default feature for the CompactFlash Storage Card with extended power. Features 55h and BBh are the default features for the CompactFlash Storage Card; thus, the host does not have to issue this command with these features unless it is necessary for compatibility reasons. Feature code 9Ah enables the host to configure the card to best meet the host system's power requirements. The host sets a value in the Sector Count register that is equal to one-fourth of the desired maximum average current (in mA) that the card should consume. For example, if the Sector Count register is set to 6, the card would be configured to provide the best possible performance without exceeding 24 mA. Upon completion of the command, the card responds to the host with the range of values supported by the card. The minimum value is set in the Cylinder Low register, and the maximum value is set in the Cylinder Hi register. The default value, after a power on reset, is to operate at the highest performance and therefore the highest current mode. The card will accept values outside this programmable range, but will operate either at the lowest power or highest performance as appropriate. Features 66h and CCh can be used to enable and disable whether the Power On Reset (POR) Defaults will be set when a soft reset occurs. The default setting is to revert to the POR defaults when a soft reset occurs.

Write Multiple Command Note: The current revision of the CompactFlash Storage Card only supports a block count of 1 as indicated in the Identify Drive Command information. This command is provided for compatibility with future products which may support a larger block count. This command is similar to the Write Sectors command. The CompactFlash Storage Card sets BSY within 400 nsec of accepting the command. Interrupts are not presented on each sector but on the transfer of a block which contains the number of sectors defined by Set Multiple. Command execution is identical to the Write Sectors operation except that the number of sectors defined by the Set Multiple command is transferred without intervening interrupts. DRQ qualification of the transfer is required only at the start of the data block, not on each sector. The block count of sectors to be transferred without intervening interrupts is programmed by the Set Multiple Mode command, which must be executed prior to the Write Multiple command. When the Write Multiple command is issued, the Sector Count Register contains the number of sectors (not the number of blocks or the block count) requested. If the number of requested sectors is not evenly divisible by the sector/block, as many full blocks as possible are transferred, followed by a final, partial block transfer. The partial block transfer is for n sectors, where: n = remainder ( sector count / block count ). If the Write Multiple command is attempted before the Set Multiple Mode command has been executed or when Write Multiple commands are disabled, the Write Multiple operation will be rejected with an aborted command error. Errors encountered during Write Multiple commands are posted after the attempted writes of the block or partial block transferred. The Write command ends with the sector in error, even if it is in the middle of a block. Subsequent blocks are not transferred in the event of an error. Interrupts are generated when DRQ is set at the beginning of each block or partial block. The Command Block Registers contain the cylinder, head and sector number of the sector where the error occurred and the Sector Count Register contains the residual number of sectors that need to be transferred for successful completion of the command, e.g., each block has 4 sectors, a request for 8 sectors is issued and an error occurs on the third sector.

This command writes from 1 to 256 sectors as specified in the Sector Count Register. A sector count of zero requests 256 sectors. The transfer begins at the sector specified in the Sector Number Register. When this command is accepted, the CompactFlash Storage Card sets BSY,then sets DRQ and clears BSY, then waits for the host to fill the sector buffer with the data to be written. No interrupt is generated to start the first host transfer operation. No data should be transferred by the host until BSY has been cleared by the host. For multiple sectors, after the first sector of data is in the buffer, BSY will be set and DRQ will be cleared. After the next buffer is ready for data, BSY is cleared, DRQ is set and an interrupt is generated. When the final sector of data is transferred, BSY is set and DRQ is cleared. It will remain in this state until the command is completed at which time BSY is cleared and an interrupt is generated. If an error occurs during a write of more than one sector, writing terminates at the sector where the error occurs. The Command Block Registers contain the cylinder, head and sector number of the sector where the error occurred. The host may then read the command block to determinem what error has occurred, and on which sector.
