Thanks all for the reply.
I don't flash ...

I just wanted to know if this BIOS is right
for  Voodoo5 5500 PCI.

I run Quake3 with VOODOO1.
Here are my results (CPU P3 4.5x124=558 MHz)

......... 512x384...... 640x480
MesaFX ....42 ...........30.2
3DFXICD ..43.5 ........30.4

With 3DFXICD i had some texture problems (mirrors,portals)
with MESAFX none problem great quality.

This Driver work FINE. If you want more V2 drivers go
(http://www.falconfly.de/voodoo2.htm)
The Diamond Drivers work but are very old
only DirectX 6 compatible.

Last night i tried mesafx 6.1.0.8 with VOODOO1 and work FINE !!!
Here are my results with Quake2 (CPU P3 450 Mhz)

   640x480      512x384
minigl    34.5      50
mesafx   29      32
3dfxICD   34      46

The MESA_FX_MAXLOD doesnt have any effect on voodoo1.

PS.
Latest Quake2 3.20 use SGIS MULTITEXTURE only.
There is a new port that use SGIS and ARB but
the ARB dont work good with MESAFX.

Quake2 and MESAFX

CPU P3 450 Mhz
Graphic Card:Voodoo5 5500 PCI

1. Althought i have my  desktop at 16bit, Quake2
with MESAFX run at 32 bit.

Here my console messages

... using desktop display depth of 16
... calling cds ok
creating DS buffers
... using primary buffer
GL PFD color(32-bits) Z(24-bits)

2. With MESAFX i have not multitexture
... GL_SGIS_MULTITEXTURE not found

3. The framerate with MESAFX is 50 fps (640x480x32)
   with GLIDEXP is 80 fps with multitexture (640x480x32)
   with GLIDEXP is 96 fps without multitexture (640x480x32)

I tried misc envars but no luck.
Any suggestion...

Thanks Voodoo5 for your reply.
