ok so im guessing you sucsessfully installed window 98 on the machine. im not quite sure what problem your trying to solve, the fact that it wont run the windows 98 cd, or if your trying to figure out how to get the graphic card drivers? also im guessing this is a desktop. if it is just open the case and check out what model the video card is. also most nvidia cards will tell you what model it is at startup just pay attention to it.
