Thank you. Unfortunately that didn't work for me either. I'm assuming I'm doing something wrong or there's some other wonkiness going on here. I'll have to spend some more time with it when I get a chance.

Did you ever get an adapter working? I have the same mouse and snufkin's wiring as well as the documented wiring for the 68666 adapter in the same thread don't work.

what comes to mind spontaneously, should the reset LED on the POST card go out shortly after the mainboard was started? or did I understand something wrong? It does, reset only lights when board turns on (then turns off) and the same behaviour when power is cut. Sorry if I wasn't too clear on that.

None of the chips get super hot, the only ones that get noticeably warmer is the CPU, and to a lesser extent the larger SiS chip. For the voltage regulator, I think it's working as intended but I'm not 100%. If I'm looking at the datasheet correctly, pin 1 (leftmost in all my pictures) I'm measuring …

Alright, delayed update but the first POST card I bought didn't actually work in ISA slots. Got a working one now; all my voltages are good, clock LED is solid, frame LED is solid and the reset LED lights when the board is turned on or off, but I get no post codes whatsoever. Since the BIOS chip was …

Ah, got them mixed up. Thought EDO predated FPM. Tried with some FPM RAM but made no difference. Removed the RAM and plugged in a (known working) speaker, and nothing. Speaker gets power but makes no sound. I also tried the CPU in another system I have just to make sure it didn't die in the process …

Unfortunately I don't have a POST card, should probably pick one up for situations like this. Here's the board currently: http://imgur.com/a/meDGoOk I have an 8MB, 60ns EDO SIMM installed.

Alright caps all reinstalled, jumpers reset, no shorts. PSU comes on normally but I get no video, CPU doesn't feel hot at all. I've double checked jumpers and I'm confident they're set correctly. I may have missed some, there are a lot on this board but the only ones I skipped had to do with setting …

TheMobRules is right about the short circuit. I have often noticed this behavior of the PSU in the event of a short circuit. I think I would check everything again. All soldering points, polarity of the caps, short circuit on the caps, etc. If you can't find anything here, then I would also check …

Yeah, you can start by checking the caps that are connected to 5V. Tantalums are usually the culprits, but other components may have shorted. Also, make sure the 5V line is actually shorted, sometimes it measures very low resistance and the multimeter beeps but it's OK, an actual short should …

PSU refusing to turn on means there's a short in the board (especially considering that you have verified the PSU to be in good working condition). I would guess one of the tantalums is shorted, most likely in the 12V or -12V line. Did you replace all the tantalums or are there some of the old ones …

Update: Got all the caps replaced, flashed a new BIOS chip and attempted to power the board on. No magic smoke, which was good, but also nothing at all happens. The PSU fan doesn't come on, it makes a very faint almost buzzing sound, and that's it. The PSU is good (verified it was still good after …

I have a Rev.8a board but there shouldn't be many differences regarding the caps. In my board these are the values: TC1,TC2,TC6,TC7,TC8,TC11,TC13,TC15,TC16,TC20,TC21,TC23,TC27,TC29: Tantalum, 10uF 16V TC4,TC5: Tantalum, 10uF 25V TC3,TC26,TC28: Electrolytic, 330uF 10V Hope this helps. By the way, if …

Hi all, I've got one of these boards that appears to have had all its caps ripped off (there's just a couple left around the ISA slots). I realize this might be fruitless, but if anyone has one of these boards (rev 8B) that could tell me the value of all the caps I'd be super appreciative. https:// …

Thanks guys. Shame it doesn't support Pentium MMX CPUs but I'm pretty sure I have a Pentium 133 somewhere to at least test it out. Can I dump the BIOS image from DOS? I don't have an EPROM flasher to do it otherwise.

You can always install a network card and transfer files that way. It'll be faster than using floppies or CDs Never occurred to me that that would be possible, will keep it in mind.
