VIEWTOP 3D Vulcan (B3D-fx2) Drivers for 95,98 and NT. Viewtop Vulcan is a VooDoo Rush card, with or w/o TV output.
I received this driver from Emiel of Nederland, thank you very much Emiel!
Unzipping gets you three subdirectories /vt/Win95, /vt/Win98, and /vt/winnt.
I had no trouble at all installing from the Win98 dir on my 98SE system, and it worked perfectly.
