Hello,
i have a problem with my voodoo 2 card installed with windows xp.
The primary card is a ATI 3D Rage 2C AGP. I have installed the fastvoodoo v 40 driver but when i want to choose an resolution higher than 800x600 the monitor goes black and displays an "out of range message". How can i go to 1024x768.
I hope somebody can help me.

If I recall right, its impossible to get a 1024x768 resolution with a single V2 board. If you want this resolution, get a second V2 ( same amount of ram, same manufacturer ) and SLI them together ( SLI = Scan Line Interleave ).

Since almost all games use double-buffering + depth buffer, it all boils down to simple math (with Voodoo2's 16bits/pixel):
(2 + 1) * 800 * 600 * (16/8) = 2880000
Whereas:
(2 + 1) * 1024 * 768 * (16/8) = 4718592 > 4194304 = 4Megs

The Voodoo2 has a 4MB framebuffer. If you use 2xVoodoo2 in SLI, the framebuffer gets doubled (that is, 8MB).

Possible with 1 Voodoo2 to reach the 1024*768 if you can disable the z-buffer (was allowed with some "old" games) or you can try to get a Wicked3D Voodoo 2. With this card and the wicked3d drivers, you can reach the 1024*672 with 1 Card but under Win9x.
