Each individual drive has 4 jumpers to set a SCSI ID from 0 to 15. You want
one drive set to SCSI ID 0 as the boot drive. The other drives have
non-conflicting SCSI IDs, usually in sequence. The end of the SCSI bus (cable)
must be terminated, having a gizmo attached to absorb rather than reflect the
signals back down the cable. NOTHING can be done from the BIOS.
If the system does not see the hard drives, there are a couple of possibilities:
1. The SCSI channel to which they are attached is either malfunctioning or set
as Disabled in the BIOS.
2. The SCSI ID jumpers are incorrect and conflicting.
3. Either cabling or termination is incorrect.
When th computer powers up, the narrow SCSI adapter to which the tape and CD-ROM
are attached is obviously working OK. It is probably an Adaptec 2940-series,
and displays its own identification text and copyright notice before polling its
SCSI drives.
The on-board SCSI channels are Adaptec 7895 (IIRC) or similar. Do these
channels also display identification text and copyright notice? If not, then
they are disabled in the BIOS. If so, then look at jumpers and cables. You may
need to get specs for the drives to figure out the jumpers... Ben Myers
