This driver is for the ATI ES1000 chipsets found on Intel's latest motherboards (server). The driver is actually the same driver as ATI's Radeon 7000 & Rage XL cards. This driver will only work in Windows 2000/XP/Server 2003 both 32/64 bit drivers are enclosed. These drivers will not work in Vista. This card isn't a hightech one so the wddm driver Vista installs is sufficient.
