Where to get driver for old Video card : ATI - 264VT2 PCI for windows XP

I thought to do dual monitor but the other card is very very old.. but not bad to use for normal day to day use.. was using it in my very first computer years years back.

Unfortunately, I had driver for windows 98 as at that time windows 98 was widely used Operating system. But now when I try using windows XP, it is detected but not working. I then tried making it primary display and it worked. but there is a prolblem, I can't do proper control like adjusting contrast etc. so I need ati's original driver for 264vt2, I think driver for windows 2000 can work on xp but its no where available to download.

thanks
