So I've almost finished my Dream 97-98 (-actually-more-like-99) Build.

The specs: Pentium II 400Mhz, Aopen 440BX chipset mobo, 64 MB of RAM, Voodoo2 12 MB, Matrox G400 16 MB AGP, Windows 95D.

There's still one problem though. I can't gat OpenGL, specifically Quake 2, to work with the G400. The 3dfx OpenGL mode runs fine. Direct3D games work fine.

I've disabled bus mastering.

I've tried all the driver versions from Phil's website https://www.philscomputerlab.com/drivers-for-matrox.html

I've tried swapping the ICD dll file in the Windows\System folder with the latest one I could find in the VOGONS driver library. The game either crashes or reverts to the software renderer.

I've tried to manually swap the default OpenGL renderer dll file for the TurboGL dll file. I get a black screen with the game running in the background.

I'm out of ideas at this point. I mean, I know I can run OpenGL games with the Voodoo2, but the inability to run them with the G400 triggers my OCD 😜
