Thanks. I had started doing that with no luck. Unfortunately, I'm at the
latest BIOS Tyan offers and it has no provision for forcing interrupts.
I had moved the disks to channel 2 because I had an older CDROM on the
first (external connector) and thought it might be a conflict (SCSI3 vs
SCSI1). No luck there either.

At this point I believe the most efficient use of my time will be to
ship these all back and get them replaced with something a bit more
compliant.

Thanks for all the help and advice,
Robert
