Hi there, I'm trying to figure out what's happening here. I'm running Warcraft 2 on my DOS machine. Whenever I just run it, CD audio will not work, no matter if it's enabled or disabled in game and no matter where the volume slider for CD audio is. Now if I quit the game and go into my audiodriver …

I agree, this sounds like the board is bad.🙁 Yeah, the fact that with the exact same setup, one board runs and one doesn't kind of proves that pretty convincingly in my opinion. What's funny is that the old board now runs with the exact jumper setup you posted except for JP 11 1-4. These should be …

That old PSU looks particularly crappy. Either an ATX to AT switch (you can buy em or make one for cheap) or a new AT psu would me my suggestion. Both PSUs never had a problem running the old board that has since been reinstated. I bought either as replacement for the PSU that came with the PC …

Did you try reflashing the BIOS EEPROM of the new board? Yes, I did do that at some point before getting it to run for the first time. BTW have you tried putting a new CR2032 in that socket? Maybe the battery the seller included wasn't new but NOS and has run out of juice by now. Some boards need …

Yup, just set up the "new" mainboard exactly the same and no picture. Old mainboard, working: https://i.imgur.com/ssNPneJ.jpg New mainboard, not working: https://i.imgur.com/tFxXX4N.jpg

Sooo, I cleaned the CPU socket of my old mainboard and hooked it up with the SL27J today, figuring that if this might kill that CPU then so be it. I think that "new" mainboard is actually the problem.

What do you guys think about getting a thing like this as well?

Oh, right - I simply missed that jumper. Have you tested with the 200MHz CPU as well (configured for 200MHz of course)? Maybe one is bad? Otherwise I'm afraid there are failing parts in this setup, and without a set of known good parts (or better equipment) troubleshooting is a pain in the ass. You …

You might want to invest in one of those $7 post diag cards from ebay Would this be something? https://www.amazon.de/4-stellige-Analyzer-Computer-Mainboard-Diagnosekarte-default/dp/B07BRFWRWL/ref=sr_1_1?dchild=1&keywords=post+diagnosekarte&qid=1597167450&sr=8-1 All I could find on Ebay would ship …

Changed the jumpers! These should be exactly as you described now: https://imgur.com/a/Seh1L9y Also, JP3 did have a jumper on it already (2-3) but it's black so it looked like it didn't. I tried to get it at an angle this time so it's more visible. Unfortunately, nothing has changed. No boot (no …

Here are the jumpers: https://i.imgur.com/QoeM74f.jpg And without markings in case I obscured something important: https://i.imgur.com/5IKzVA3.jpg

Thank you very much! I'm going out to the get a multimeter from the store now. Say, if I'm checking the voltages with the PSU connected to the motherboard with a CPU in it, where would I take the voltages from? I only found tutorial videos where people put the multimeter directly to the PSU with a …

Thank you all for the insightful responses. I didn't expect anyone to take the time to read all that, so I'm very thankful to all of you. Here is what I've tried in response. I powered the system on between each of those steps. Tried to turn it on to see if the problem was still persisting. Same as …

Dear VOGONS people, I come in the need of help. I've been lurking these forums for the past couple months, mainly through google search results when trying to find solutions for various problems while building some old PCs. Eventually, both of my machines were in a satisfactory state, at which point …
