It would be best to concentrate on Dos Tomb Raider as there are no potential Windows driver or other software issues that can mess things up. Make sure to use a Proper Dos boot, not run from within Windows. What I am wondering is whether Your system is getting mixed up with the onboard video. Try …

You need MiniGL for GLQuake. What Monitor are You using? Does it support refresh rates like 70hz? What Windows 3DFX drivers have You tried?

https://www.vogons.org/download/file.php?id=157969&mode=view I would try playing around with memory sizes first. It likely won't work with FBI disabled. I could get Tomb Raider working with 1MB available to the FBI. You can definitely still get just a non textured Lara with TMU or it's memory …

Mine froze as it had a bad Ram chip attached to the FBI. I could get it working by limiting the ram available to 1MB. In autoexec.bat You can try disabling the TMU or FBI chip and limiting the memory to each to 0, 1, 2MB. i would first try disabling the TMU as tomb raider will work with no texturing …

It won't be the oscillator. MOJO is correctly identifying the DAC, TMU, and FBI and would not be able to without the oscilator running. You can try disabling the TMU/FBI or limiting the Ram amount and see if that gets it working. see my post here 3dfx Voodoo 1 fault diagnosis and repair

You really need to test it in Pure Dos mode with Tomb Raider 3DFX executable. Also You can get hold of the 3dfx sdk and run MOJO (in dos) which will help with diagnosis.

Well done on the successful repair. I've had no trouble yet with these ram chips from Aliexpress. Good that You tested first in a card with empty sockets.

Update: I have tried different Environment variables and got no sucess. There is also good and bad news. Good: I found one loose leg, soldered it and got init with TMU ram: 0MB, but that was the original problem. And now the bad news: I swapped the memory of one TMU with the noname 12mb single- …

The ISA bus runs at 7-8mhz standard but can operate at 11 and maybe a bit more or so with certain cards that can handle that. Actually I realised You are talking about the memory chips that can be on the VLB card as well as 72 pin memory sticks. That makes me wonder why the 25ns EDO memory on Voodoo …

I'd take a look at the right TMU. 2 Pins about number 194 look like they are shorted, but it coud just be a speck of dust.

I have a VLB motherboard with this chipset. It performs quite ok as long as You are running a 33mhz fsb. As per the photo it supports 5v cpus only out of the box but I modded it to support lower voltage cpu's. I tried a TI 486 DX2-80 but as has been reported it's slower than a dx2-66. I tried all …

I did notice the oxidised leg on the photo but sometimes that just be the way the Camera took it. Anyway Great to see another V1 fixed.

L11 doesn't look good. C105 is on an angle for some reason. I would check all capacitors and ferrites with a multimeter. The best test for these is in a pure dos environment with Tomb Raider 1 3dfx. Also have a look at my post here 3dfx Voodoo 1 fault diagnosis and repair

If You can reduce the multiplier to 5 or 6 it may work. My Voodoo 1 failed with the rectangles on screen after 600mhz with an AMD Duron or Athlon, but failed at 500mhz with an Athlon XP Barton, I think the extra cache had an effect as well.
