INSTALLTION GUIDE
Setting Method
Make sure your computer turned before open case.
HFDOM44S3Vxxx
Plug carefully into 44pin slot your computer. Caution: Make sure align pin1 host adapter interface connector with your Flash Disk Module. indicated triangle Flash Disk Module connector. Flash Disk Module used power connector cable computer. Caution: need remove your Flash Disk Module, both hands pull carefully. Check cable connections then replace your computer cover.
BIOS setting Method
Before format partition your drive, must configure your computer's BIOS that computer recognize your drive. Turn your computer your computer start watch screen message describing system setup program screen (sometimes called BIOS CMOS setup). This usually done pressing special key, such Delete, during startup. your computer manual details. Press appropriate system setup program. your BIOS provides automatic drive detection "AUTO" drive type), select this option. recommend Normal mode partition your Flash Disk Module maximum formatted capacity. This allows your computer configure itself automatically your drive. your BIOS dose provide "AUTO" drive detection, select "User-defined" drive setting enter values from table. BIOS Settings (see specification) Capacity Cylinders Heads Sectors(unformatted) Save settings exit System Setup program. your computer will automatically reboot After configure your computer, standard commands partition format your Flash Disk Module, described below.
Formatting Method
partition your Flash Disk Module with Microsoft program Insert bootable diskette into your diskette drive restart your computer. Insert program diskette that contains FDISK.EXE FORMAT.COM programs into your diskette drive. same version that your bootable diskette. prompt, type "FDISK" press Enter. Select "Create partition logical drive" pressing Then press Enter. Select "Create primary partition" pressing again. Then press Enter. Create your first drive partition. creating partition that will used boot your computer (drive make sure that partition marked active. Create extended partition additional logical drives necessary, until space your hard drive been partitioned. When partitioning complete, FDISK reboots your computer. Caution: Make sure correct drive letters that format drive that already contains data. prompt, type "format c:/s", where letter your first partition, Repeat format process partitions have created. After format your drive, ready use.

this High Imoedence. Implementation Note: Conflicts occur host data when this provided Floppy Disk Controller operating same addresses CompactFlash Storage Card. Following some possible solutions this problem PCMCIA implementation: Locate CompactFlash Storage Card non-conflicting address, i.e. Secondary address (377) independently decoded Address Space when Floppy Disk Controller located Primary addresses. install Floppy CompactFlash Storage Card system same time. Implement socket adapter, which programmed (conditionally) tri-state address 3F7h/377h when Compact Flash Storage Card installed conversely tri-state D6-D0 address 3F7h/377h when floppy controller installed. CompactFlash Storage Card's Drive Address register. This accomplished either possible, program host adapter enable only addresses 1F0h-1F7h, 3F6h 170h-177h, 176h) CompactFlash Storage Card provided additional Primary Secondary configuration CompactFlash Storage Card which does respond accesses locations 3F7h 377h.

Cnt(2) Feature(1) Write Long Sector
HFDOM44S3Vxxx
This command similar Write Sector(s) command except that writes bytes instead bytes. Only single sector Write Long operations supported. transfer consists bytes data transferred word mode followed bytes transferred byte mode. Because unique nature solid-state CompactFlash Storage Card, four bytes transferred host used CompactFlash Storage Card. CompactFlash Storage Card discard these four bytes write sector with valid data. This command same protocol Write Sector(s) command. this command recommended.

Write Multiple Command Note: current revision CompactFlash Storage Card only supports block count indicated Identify Drive Command information. This command provided compatibility with future products which support larger block count. This command similar Write Sectors command. CompactFlash Storage Card sets within nsec accepting command. Interrupts presented each sector transfer block which contains number sectors defined Multiple. Command execution identical Write Sectors operation except that number sectors defined Multiple command transferred without intervening interrupts. qualification transfer required only start data block, each sector. block count sectors transferred without intervening interrupts programmed Multiple Mode command, which must executed prior Write Multiple command. When Write Multiple command issued, Sector Count Register contains number sectors (not number blocks block count) requested. number requested sectors evenly divisible sector/block, many full blocks possible transferred, followed final, partial block transfer. partial block transfer sectors, where: remainder sector count block count Write Multiple command attempted before Multiple Mode command been executed when Write Multiple commands disabled, Write Multiple operation will rejected with aborted command error. Errors encountered during Write Multiple commands posted after attempted writes block partial block transferred. Write command ends with sector error, even middle block. Subsequent blocks transferred event error. Interrupts generated when beginning each block partial block. Command Block Registers contain cylinder, head sector number sector where error occurred Sector Count Register contains residual number sectors that need transferred successful completion command, e.g., each block sectors, request sectors issued error occurs third sector. Sector Count Register contains address that third sector. Write Multiple without Erase Bit-> Command(7) C/D/H(6) Drive Head

Cylinder High (LBA Cylinder Sector Number (LBA Sector Count Write Sector(s)
This command writes from sectors specified Sector Count Register. sector count zero requests sectors. transfer begins sector specified Sector Number Register. When this command accepted, CompactFlash Storage Card sets BSY,then sets clears BSY, then waits host fill sector buffer with data written. interrupt generated start first host transfer operation. data should transferred host until been cleared host. multiple sectors, after first sector data buffer, will will cleared. After next buffer ready data, cleared, interrupt generated. When final sector data transferred, cleared. will remain this state until command completed which time cleared interrupt generated. error occurs during write more than sector, writing terminates sector where error occurs. Command Block Registers contain cylinder, head sector number sector where error occurred. host then read command block determinem what error occurred, which sector.
