>Organization:
Dignus, LLC
>Environment:
Adaptect 1542B - Version 3.10 (from 1988)
>Description:
The probe in version 3.1 for adaptec drivers checks the
GEOMETRY_REG. If the value is 0xff or 0x00, the probe
succeeds. Unfortunately, for version 3.10 of the 1542B,
the value returned is 0x7f. This could also be because
there are no disk drives on the SCSI bus, only tape drives.
>How-To-Repeat:
Get a version 3.10 Adaptec 1542B, put nothing on the SCSI
bus and watch the probe fail.
>Fix:
The following context diff to /sys/dev/aha.c corrects the problem
for me. It also adds a little to the debugging information
when you boot with the -v option.
