This is the only driver for Windows 2000/XP I have found that works with the STB Nitro DVD card used in Gateway Pentium II computers. If you upgrade your Gateway to W2K or XP you need this file. Unzip the file and direct the add hardware wizard to it. The add hardware wizard will say Chromatic Research as the video card type. Chromatic Research in fact manuafactured the Mpact video processor chip on these AGP video cards.
