Well thanks to the people who responded by email, but none of the ideas worked.
So far I have found out that when the Adaptec controller is in the machine with
a drive attached, then even though the ESDI controller only has 1 drive and the
SCSI controller 1 drive, the ESDI controller will tell all and sundry that it
has 2! disks attached. This is what makes Novell crap out! It tries to read the
parameters of the second non existant disk and dies. Only when the ESDI's ROM
is disabled will Novell work, but then the ESDI controller reports 0 drives.
The EPROMs on the controller are marked 1987. Is there a bug in these that will
cause it to have a phantom drive, when there are 2 controllers each with 1 disk
attached?
