I'm having a strange problem with a SCSI ST296N on a 386SX.  When I boot the
machine with Video Bios shadowing turned on, the hard disk is not reconized.
If I turn video shadowing off, the system works like a champ.

I swapped the vga card with a different manufacturer, the scsi adapter, and
pulled all the other controllers off the bus, but nothing helped.  The only
component I haven't swapped is the system board.  

If I install a ST506 type drive, I don't have this problem either.  I tryed
restrapping the ST02 adapter for a different BIOS address, no help either.

I am trying to determine if this is a compatibility problem with the SX, or just
a bad system board.

Does anyone have this same configuration that doesn't experience this problem.
