How can I replace Win-7 video driver with Vista or XP driver?

[Yousuf Khan]

The hardware ports belong to a proprietary data-acquisition interface
card that does not have any windows drivers.

Ah, okay, I understand now. I was thinking you meant direct port access
to the VGA hardware, which was common in those old days of DOS.

So unless there's something about virtualization that I don't
understand, I can't see how my 16-bit app is going to be able to
directly access the real physical ports through the virtualization
layer.

Yeah, some virtualizers allow you to exclude certain ports as you need,
to act as pass-through ports. But I don't know if the Microosft XP Mode
VM is one of those. Usually most VM's only allow USB ports to be passed
through.
