Video card doesn’t exist

I am running a fujitsu pIII500. The
original driver disk has been misplaced.
The online documentation for my product id says I have an intel 810e graphics card. I downloaded the drivers from the intel site and everything was great. I dual boot myworkstation with Win NT 4.0 so I downloaded the nt drivers at the same time. When i try to run thee setup program it tells me that the 810 video card is not in my system. The drivers work fine in Win 98 with no problems at all. How do I know if there really is an 810 card. There are no tell tale names o the on board chip. Help I want NT in more than 16 colours
