Using module aic7xxx that is bundled with Caldera Open Linux Standard
1.1, (kernel ver. 2.0.29) everything works great in probing SCSI disks. When the
pre-2.0.31 kernel is used, SCSI1(Fuj) is detected as SCSI0 and SCSI0(Microp) is
not found using the AIC7xxx module.
I am at your disposal in helping you test any fixes you may come up with.
Included at the end of this document is some debugging aids.
We truly appreciate your work!

I will give an output of the /var/log/messages file as the adapter
