How to find a video driver

[gingem]

I have a DOS based program that I have to run over a network and I have managed to make it run on my Vista Home Premium system. The problem that I have is that Vista video drivers won't allow the program to run in a full screen mode. Is any special way that I need to do to I guess downgrade my video driver to make it work for the DOS program but still make it work for Vista?

As I know, Vista doesn't have dos support so the only way to run a dos application is to run it in window mode so if you really want full screen try virtual pc.
