This file covers the 51, 61 and 71 versions of the S3 AGP 3D video card.
Just uncompress into a folder, go into control panel, system, device manager and then Display adapter. Click on the adapter and then click Remove and then Refresh. It will ask you where the video driver is, so just point it the folder that you uncompressed it. Restart the computer and it should work. If you have any problems with this driver you can email me.
