The 3dfx enthusiasts of 3dfxzone.it have cooked up new Windows 2000 and Windows XP drivers for 3dfx's Voodoo 3, 4 and 5 series graphics cards! I'm not sure what's new though, the changelog only lists the name of the files they updated.
After 1.4 release, it's time of new SFFT 1.5 driver. This software is based on Unified Architecture supporting by one package all Voodoo3 family, including Voodoo3 2000, Voodoo3 3000 and Voodoo3 3500 cards, as well as all 3dfx VSA-100 products and so Voodoo4 4500, Voodoo5 5500 and Voodoo5 6000 cards, is on line.
It's requires a 3dfx card as a primary display adapter or as a secondary device used to extend the desktop as well and supports Microsoft Windows 2000/XP (32 bit) or XP x64 (64 bit) as Operative System.
