OK any future person looking for a fix for this, after some more digging I've found that any Fitzquake version >= .70 introduces a refresh rate setting that has a bug in windows 9x, where the refresh rate reads as 0 for all video modes and causes the game to update extremely slowly. Version .65 is …

Thank you for the list! I'll try out some of the others. Sorry for the confusing wording, I mostly mean to get overbright/fullbright support and fix the gamma. GLQuake just looks really off relative to software mode but I'd still love to use my voodoo 5 to accelerate it. I tried a Geforce 2 Ultra …

Hey all, I'm trying to run a good source port of Quake that can look as close as possible to the software mode but use my Voodoo 5 5500 for acceleration. I believe FitzQuake is a good match for this so I'm trying to get it to run. Has anyone had any luck with this? When using the official 3DFX ICD …

I haven't had GUS MAX for a long time so I can't test this anymore but GUS MAX has codec that requires ports of its own. I remember having some configuring problems as well. If I remember correctly setting the GUS MAX to 2x0h requires 3x0h to be available as well so if you have GUS MAX port set to …

Some more info: I tried the GUS and HardMPU in a Pentium-120 system, and they had the same issue where the HardMPU won't work when the GUS is inserted. I then removed the HardMPU and tried my Awe64 Gold with the GUS Max, with these results: Doom works with the Awe64, without even initing the GUS …

If I have time this evening I'll remove the GUS from the build (that currently contains the MMSN826 and AWE64 as well) and confirm it it's the cause of these issues. I'd be interested to know what happens with you, I can't be the only one experiencing this surely :) firstly, irq2 is a bad irq to …

I'm pulling my hair out trying to figure this out, I'm wondering if anyone has experience with this or any ideas. I've been building my ultimate 486 machine. It currently has a Soundblaster 1.5 @ 220 IRQ 5 DMA 1 and a HardMPU @ IRQ2 330. Everything works fine using the HardMPU to run an SC-88 and MT …

It's because it only passed that code without a video card that I'm asking. Obviously it shouldn't just die like that with VGA installed but it does - so there has to be something related to that too. And I doubt you'd be interested in running this system headless. Last time I had issues like this …

Anyone have any ideas with that new info? Did you try all 3 VESA slots? Typically you'd use the one closest to CPU but I have a 386/486 mobo that seems to have jumpers for 50MHz operation on slot 1, and that is actually the second one from CPU. And what other VGA card have you tested? A Trident …

You heard the RAM count beeps. Means it's a matter of time to get it working. Have you tried removing all cache chips? If legs are oxidized it could prevent booting. Any loose components? You could try holdnig the motherboard down by pressing in the middle or other parts... The cache chips are new …

Tried DX2 66 and 50 CPUs, and also flashed the BIOS with the newest one with the help of a friend. It still has the same issue, but one single time when it didn't have the video card in, we saw it get way farther on the POST card and heard it do the memory check beeps. We plugged in a video card …

Does the POST always stop at the "0D" code? If yes, that's related to the video initialization, so it might be worth to investigate this part, maybe test other video cards in different slots. If you're using a VLB video card, it might be worth to also try an ISA card. Yeah it always stops there. I …

Your mobo has tantalum capcitors, those rarely go open. The usual mode of failure is cracking due to thermal cycling, mechanical stress or just manufacturer defect to begin with - and that invites moisture and oxygen. Tantalum is pretty reactive, the capacitor will typically self-destruct in short …

I'm able to get it down to 3.6 (but not 3.3) by messing with the voltage setting jumpers with the CPU removed, though it still doesn't post and the 3.8 is the official jumper layout. I think the voltage is OK, it's not uncommon to have it a bit higher to compensate for drop with load and/or …

Thanks! Ok I tested the voltage on Q4 and it’s nowhere near 3.3v, it’s .6 and 1.2. What would that mean? Sounds like that transistor has failed, which means the CPU won’t be getting the right (or stable) core voltage. Replace that transistor and you may find the board comes back to life! Recently …
