said: My brother in law has a Compaq Presario 4503 -166MMX - 2.1GB H/D, WIn 98. THe video chip is an S3 Trio which shows as having 1MB video RAM. We have found this is insufficent for a lot of the latest games and some won't even start. The Compaq site says the Video RAM is upgradeable. How do we go about doing that? I guess the other option is to get a good quality 2D/3D PCI card and add it in? Any thoughts would be appreciated. Thanks Darryl Lennane
