ATI Radeon™ HD 4850 Drivers & Support in the current version's official release notes for the 32 bit version of Windows Vista and Windows 7: Windows XP - 64
Apr 13, 2007 · I just got 2 VisionTek Radeon 9250 PRO PCI video cards that I installed on two engineering PCs. I installed the video cards with no problems and windows (xp) detected drivers which made both cards fully functional. However, the only thing installed was the drivers for the cards, not the ATI Catalyst or ATI Control Panel or anything.
