SCSI and AT bus support?

Bill, I think I understand what you are saying, so here goes.  The SCSI
adapter can coexist with the AT ESDI controller with SCO 2.3GT.  The SCSI
devices become the slave devices and you must boot off the ESDI drive.
But other than that, it sounds like this will solve your problem, that is
if I understand you correctly.
