Are there ATI Radeon x1300 PRO drivers for XP?

just picked up an ATI Radeon X1300PRO PCI-E 256M Graphics Card 109-A67631-12 and was hoping to install it on my Dell Dimension 8250 (which right now has a GeForce4 MX 420) but i can't seem to find an XP driver for it, despite it being listed as XP compatible. Curious if yall knew any more than i do about this
