Can this be done? I've found more than one reference that appears to
imply that if your machine boots from a SCSI disk that you cannot add an
IDE drive. Surely I'm misinterpreting what I've read.

FWIW I'm trying to add an IDE disk to a running SCO 3.2 system that
already has a single SCSI hard disk (2 partitions) and a SCSI tape
drive. I was hoping to "image" the disk to an IDE drive for setting up a
newer system.

The bios sees the new IDE drive, but no combinations of mkdev hd x x
seem to work.

Is this approach doomed from the start? Should I just move the SCSI
controller and drives to the new box?

Any comments appreciated.
