Update: with some tips from @bloodem I was able to get proper GPU performance under Win9x on the K8V-MX motherboard. I downloaded the earliest available BIOS version from Asus' website (v0112) and flashing that completely fixed the problem. As the original thread starter suggests, there seems to be …

TL;DR - you might be running into an issue similar to the one I had with the MSI K8T NEO-V motherboard: https://www.vogons.org/viewtopic.php?f=46&t=76662 For some reason, that motherboard has an AGP related bug that causes it to run at a third its normal speed in Windows 98 (and, boy, I sure tried …

Thank you! Desoldering was very quick and easy with a pair of tweezers, kapton tape and a pretty cheap ($20) industrial hot air gun. For soldering I also used a cheap Basetech ZD-99 soldering "station" with a 3 mm flat tip.

UPDATE: I had some more time this weekend to play around and finally managed to fix the Voodoo 2 board. It was a very fun ride, so now I'm actually thinking of searching for more damaged Voodoo 1/2 cards and try to fix them :-) Anyway, long story short, I narrowed the issue down to four FBI memory …

Call me crazy but if I were to bet money I would put it on those SMD electrolytics having leaked onto their pads and causing cold solder issues until the card warms up.. No, the capacitors are fine, one of the first things I checked. We are actually two very, very, very different people :P I got …

Thanks, Doornkaat. I actually ended up checking the continuity of each individual pin for both TMUs and all RAM ICs... everything looks good. Unfortunately, it's probably an issue inside one of the chips/RAM ICs, but I have no idea how I could ever identify which one it is...

I have a Gainward Voodoo 2 12 MB that's been sitting in storage (in perfect conditions, in an antistatic bag) for quite a while - last time I used it many years ago it was working fine. However, it's now faulty and the behavior is very atypical: 1. when the card is cold, it freezes in GLQuake / …

Thanks a lot to both of you! Managed to overclock my CPU to 266 MHz (no voltage bump required 😀)! I had actually seen the "T75" jumper setting, but it did not occur to me that the "T" stands for FSB 😁

Hello, By any chance, does anyone have a manual for this motherboard? There doesn't seem to be one anywhere, it's like this motherboard is a ghost. 😀 I'm mainly interested in its overclocking potential, trying to understand if I can go above 66MHz FSB. Thanks.

Wow! Thanks again, keropi :) Very useful information, as always. I actually didn't know about the CTRL + ALT + Plus/Minus combo. Now, the only issue is that, on the AM5x86, the performance drops too much (7.8 FPS in 3DBench 1.0c). That's way too slow... It seems that it disables both the L1 and L2 …

Hello everyone, I recently got my hands on a very nice Zida 4DPS ver 2.1 board with 16 MB FPM RAM (I tried a few EDO sticks but they either don't work at all, or they cause extreme instability). Anyway, the current config is the following: MB: Zida 4DPS ver 2.1 CPU: AMD AM5x86-P75 133 MHz RAM: 16 MB …

So, in case anyone has the same issue on a SS7 PC, these are roughly the steps to get good sound in Jazz Jackrabbit (with a SB16 or an ESS AudioDrive 186x): Replace the MDRV004D.MUS file in the Jazz Jackrabbit folder with the one provided by keropi a few posts above (thanks again!) Decrease your CPU …

Well... did more testing and it turns out that the sound issues with this game are caused by speed sensitivity, and some cards are more speed sensitive than others. The SB16 needs an even slower CPU. I had already decreased the K6-2+ speed to 200 MHz, but it isn't enough. After I disabled the L1 …

Set the following environment variable and initialized the card with diagnose /s: SET BLASTER=A220 I5 D1 H5 P330 T6 A great card, with beautiful, crystal clear sound in most games... but not Jazz Jackrabbit :D In Jazz it's even worse than the …

Hello, Sorry for the necropost. I stumbled across this thread after I tried to play Jazz Jackrabbit using an ESS AudioDrive ES1869 (in Windows 98 SE - MS DOS mode) This card has great sound in most games, but in Jazz, no matter if I select Ultra quality sound or not, the sound will play at very low …

So... I finally gave up on this board. It's a great board for early Windows XP, but something is killing its performance in Windows 98 and as much as I tried, I could not find any workaround. 🙁

Unfortunately I didn't use any sound cards. I usually add sound cards later, after the initial performance and stability tests. Also, the first thing I do is to always disable the onboard sound and other unused devices like serial / parallel ports
