Ok, so the next question is a bit more complex.

If I've got a VME interface board, and I'd like to run a program that runs
under DOS on an ISA-based interface that does the same thing as the VME
board, will that program work with the VME board or is the entire
hardware/interrupt structure completely different?

In other words, does MS-DOS think it's still running on an ISA system even
though it's on a VME system? Or was there a special MS-DOS made for VME
systems?

I know I'm engaging in wishful thinking but I'm wondering if the DOS
software will work with the VME board. I suppose if its going through
BIOS then maybe, but my guess is that the software is directly accessing
the ISA board hardware and will not work with the VME board in a VME
system.
