Looks like the cache is a good lead! I removed 128KB last night, and a leg from a chip came right off...I suspect it may have been fragile already. I disabled all cache in the BIOS and ran memtest again overnight, no error! It made a full pass and a half and was still running. So I re-enabled the …

Good idea, didn't suspect anything in regards to cache. I will test that. Thanks for the tip! rasz_pl wrote on 2024-02-25, 20:47: Id look at all ETEQ pins too Thanks, if cache ends up a dead end I'll get the microscope and give it a good look tomorrow.

I thought so but was too quick. I still get random problems. Even worse, I thought I narrowed it down to memory manager and everything was fine without it, but I just had another similar freeze in that configuration 🙁 back to step 1...

I *may* have found the issue. It's very possible memtest really threw me off and made me waste a lot of time... trying more games using conventional memory only, I couldn't reproduce any freeze, which made me realized that my standard DOS menu I copied off my 486 with some emm386 customization may …

With the 4x4MB and DRAM refresh set to standard I now passed the 33% test successfully as well. Those are fresh sticks made by Tiido, so I have very high confidence those are good. I'll let it run completely and hopefully it does a full pass with no error, and if that's the case I'll try some games …

Hi there, I have received a 386 board (Soyo 019H, 256kb cache) with an Am386 DXL-40. It was mostly working fine, but when I started playing some games it would regularly freeze randomly. I suspected the RAM and tried to do some memtest86+ v2.00 to check it. The board also has an IIT 4C87-40 FPU, and …

I really like the software :) the floppy issue seems to also happen on CF card. Tested two PC's, and browsing directories and files shows garbage, or does not show some folder at all. I have absolutely no file system issues outside of Mod Master so looks like there's something it really doesn't like …

Just to share that I've recently decided to finally get to it and start replacing capacitors for the first time. I had 4 socket7 and slot 1 motherboards with bulging, leaking caps and replaced them all. As recommended by Shamino, I assumed all similar capacitors were to be replaced even if looking …

I believe people are grossly overestimating the effect of (lack of) TRIM...but of course would be happily be proven wrong by real-life tests 😀

Maybe the OP is running an overclocked ISA bus or something that in combination with the riser card can end up affecting signal integrity? Thank you for your feedback. The ISA bus is devinitely not overclocked, but maybe this motherboard has some other sensitivity that make it incompatible with the …

Interesting input, thank you all. My goal was in the end to build a 386 in this case, waiting on a new motherboard. I guess the option would be to find an alternative riser with a proper ground plane, if all else fails... it seems to be a pretty standardized format. The case is absolutely beautiful, …

Found an eBay listing for a very similar riser in a somewhat big stock and a lot of sales, no capacitors or anything either..it's kinda surprising to me that they were/are popular if they were so fundamentally flawed, am I right to wonder?

As a test, I ask to stick the riser in the complete other end of the motherboard from where it is now, the bottom ISA slot, where the bios is, Yes, I know that it won't fit in the case in any way like this, that's why it's a test, and run your programs again for signs of instability & crashes. I …

Very interesting, now I didn't expect that! I don't see any capacitor anywhere on the riser...guess the bottom-left and bottom-right holes/pads look like there were some that were removed...? Here are two new pictures of both sides, had to use the flash because of the low light, but hopefully it …

ISA riser card ends up in the top ISA/VLB slot. I have since switched the previous 486-DX25 that was in there for a 486-DX33 (and changed the necessary jumpers). I have less issues than before, which is good, but now the PicoGUS only gives me sound but music in Epic Pinball and Jazz Jackrabbit in …

Thank you. Mmmh...currently trying another motherboard, and it seems like the same issues don't happen. Could different socket 3 motherboards send varying amount of current per slot? I was kinda expecting some kind of standard. continuing my tests.
