You have a Rage 128 Ultra. It uses the ATI Rage 128 Pro chip, but the card is not made by ATI. The card is usually found in Dell computers, and uses a slightly higher clock speed than the ATI cards, hence the \"Ultra\" labelling. You can use the generic ATI drivers for the Rage 128 Pro, but you will have to install the drivers manually through device manager. If you use the setup.exe to install the ATI drivers, setup will fail.
