SCSI interface card
can’t communicate
with drive
This means the device driver was not
able to locate the proper SCSI
interface card in the PC.
6. There could be a conflict with another board installed in the
computer. The Future Domain SCSI interface card is a memory mapped
board and can be mapped into four different addresses (the C000 and D000
memory segments). See Installation Manual packaged with the interface
card for information on changing jumper addresses.
8. Check whether a 16 bit VGA card is installed in the computer.
A 16 bit VGA card may conflict with all four Future Domain Memory
addresses. Set the VGA card to 8 bit mode.
7. If using a memory manager such as 386^MAX, QEMM, EMM.SYS (or
something with a similar name), make sure that the memory manager has
excluded the memory range used by the Future Domain interface card.
Check your memory manager instructions for the details on this. Type this
into the Config.SYS after the line that calls the memory manager:
EXCLUDE =C800-C9FF or RAM=C800-C9FF.
It is a good idea to do this even if no problems are evident.
5. Power down the computer, disconnect the cable from the back of
the PC and restart the computer. If you still get the same message,
“SCSI host adapter can’t communicate with drive”, after you boot up, the
interface card may be conflicting with another board in the computer. Refer
to the interface card documentation and change the jumpers on card. If the
error changes to “Time Out During Selection Phase”, you may have a bad
cable or a poor connection. Re-seat the cable or change it and try again.

10. The interface card or the slot for it in the PC may be malfunctioning.
Try placing the SCSI interface card in a different expansion slot in the
computer. If you are still having problems, try replacing the interface card
