Long enough to get the basic chip and device configuration as set in the
EZ SCSI BIOS area and that's it.

We don't touch the BIOS.  Not to replace it or otherwise.  We simply
ignore the BIOS.  We replace the sequencer on the card though.  But,
that shouldn't cause the NT equivelant of a core dump.

Most motherboards will upgrade both at the same time.

Most likely your problem is an NT driver problem.
