This file will install all files necessary to use the SIS 530 Video Adapter in the Compaq 5304 Presario Series computer. It works with Win 98, SE, Win ME. Unknown about NT, 2K, or XP. It installed in Win ME with no errors. I searched for hours and what a relief it was when it installed and rebooted without an error! Finally. Thanks Compaq (now HP) for your fine product support ! It is the envy of the 21st century. What a joke.
