I'm trying to get 3 IBM 9.1GB LVD SCSI drives to work with a new install
using an Adaptec AIC-7896 (imbedded on an Intel L440GX+ motherboard).  The
ONLY way I got all 3 drives working was the following:

SCSI ID 0    ->   P7 (furthest from the controller) connector
" "     1    ->   P6 (next connector in)
" "     2 (terminator jumper in)    ->   P5 (and so on...)

with P1 going to the controller (motherboard in this case)

The only problem with that is that I need to move the last drive (SCSI ID
2) to a drive bay that the P5 connector can't reach.  I've tried every
other connector on the SCSI ribbon cable with no luck; I either get
panics as soon as the install tries to start, or everything hangs before I
even get that far.

Is this normal behavior?  Is there a fix?  Perhaps a jumper setting on the
drives (the "disable parity" jumper is off by default, for example)?

Thanks in advance,
