Scanner has two 25pin connectors one has SCSI cable the other has the
terminator 
supplied with the scanner.

Output of "cat /proc/modules" shows no aic-7XXX. This should be the
right module.

Output of "modprobe av aic7xxx":
# /sbin/modprobe -av aic7xxx
/sbin/insmod -L /lib/modules/2.2.12-20/scsi/aic7xxx.o

aic7xxx               112208   0 (unused)

"# /sbin/modprobe -av sg" reports "/sbin/insmod -L
/lib/modules/2.2.12-20/scsi/sg.o"
Finally  "cat /proc/scsi/scsi" reports "Attached devices: none"

"ldconfig" went off for a few seconds and then returned the command
prompt. No change in the above reports.

I've learned a lot from these tips. Though, I still seem to be missing
