This board is not in a bad condition, I would say it is in a horrible condition. As a minimum, you should also remove the ISA connector nearest to the keyboard connector. I believe there is severe corrosion inside. And now is alive, one year after being saved from the scrapyard. still need some …

Found this thread while looking for information related to the topic discussed here. I believe the card in question is MSI MS-3401 . Initially i thought it is a rare VLB card based on S3 911 which is a pre-VLB silicon, but my presumption was incorrect. Nice card, but clearly not Micronics EISA one. …

ah great Info thanks! JP5 6 are 1-2 short here my cpu jumper: IMG_7243.jpeg Ends up in no boot. Hmm. You had before the Am5x86 in L1 WB mode. Is it correct? Then just use the exact same setting for the Intel DX4-WB. The setting in Bios for L1 WB or WT does not matter at all, you need correct jumper …

Hi, Maybe someone could help me, because I have no idea why it looks like that. My POD83 has almost such performace as 486 DX66 when I measure benchmark. Even if I compare it with the POD83 reference in CPU-Z, it looks much slower. I have win98 SE and Voodoo 3 3000 PCI, Sound Blaster 16 ISA and 86 …

I made more tests under Windows98SE, stability seems fine with cache read setting 3-2-2-2 and everything else on best options. But after comparing the Lightwave 3D test with values from my Asus SV2GX4 I decided to give up with this board. The comparison was fair. I used the same OS, same graphics …

Here's my autoexec and config.sys My personal recommandation: Don't optimize the conventional memory when you start Windows 98. I tend to keep it the same as it was after installation. So you have already a boot menu, that is perfect. Then make a config for Windows 98, where you optimize nothing …

Update: Write 2-1-1-1 works, no problem. But for cache read it has to be 3-2-2-2. Neither 2-2-2-2 nor 3-1-1-1 was stable. So at least it is not completely of to pshipkov's setting write: 2-1-1-1 and read 2-2-2-2. With 3-2-2-2 read and 2-1-1-1 write, no crashes in Win98, also the lightwave 3D run …

I found some time to continue. All in all the EXP4045 Bios seems to be better, but my Windows 98SE installation was never 100% stable. Very often there was a data corruption and Windows tries to repair the registry. I played around and I am quite convinced that everything is stable with a cache …

Going from 256K cache to 1Mb on a 486 yields only about an 11% improvement (https://www.vogons.org/viewtopic.php?p=966683#p966683) with 512k you probably are only 5% less than 1Mb... Just going by douglars tests..... not sure why 1Mb cache be important on a 486, seems overkill :) Ask douglar what …

The weirdness continues. So because 40MHz does not seem to work, I try to install Win98SE with 33MHz again. Not working either with the Abit Bios. So change back to the Ami 2800 Bios, with setup default. Scrambled screen! OK, change to an ISA ET4000. System boots, but scrambled picture during the …

More bad news: I removed JP4 (which is obviously for the WB signal) and the board starts in L1 WT. Same crash in the Windows 98SE installation (Still slowest setting and L2 disabled!) So it is hopeless, it is not about a missing signal HITM, CACHE or whatever :-( So I can only run the board with …
