As I see it, this seems to be your problem. You were on win xp and you had the right drivers and this device worked fine. Now you're on win 98 and this device(your video) doesn't have all the functions. The drivers for XP and 98 are different at times. What you have to do is search the manufacturer's site for the drivers for your video card that apply to win 98. I run Xp and have an ATI card which ran fine. Then I made my system a dual boot( XP+98) I had the same problem you describe and I had to get win98 drivers for the 98 portion of my system. Good Luck
