So, I came back to this board.
1) I've tried a third PSU that came with a Pentium 3@1GHz system;
2) I've removed all the hardware but CPU and RAM. At some point I've even disconnected the power from all the drives;
3) I've changed EDO RAM for FPM RAM from my 486 build (that I know to be working);
4) the chipset gets warm after 20-30 minutes, but it's not too hot to touch. Not like the Pentium Pro anyways;
5) I've checked all the jumpers. The manual says that I don't need to set the voltage since it autodetects that — but I've set that to specifically 3.3v since I'm using a Pentium Pro@200 with 256KB cache.;
6) I've tried both jumper settings for +3.3v power source;
7) I've bought a PCI/ISA POST card
Generally the LED displays are giving me -- -- (no value).
Once or twice I've got C3 05, but I can't reproduce that.
If I'll quickly turn the power off and on, I'll get 00 FF.
😎 I don't see damage to any of the capacitors (no bulging) or other components
9) the motherboard is set on a wooden board, it's not in the case anymore
What else can I try? I've got a feeling that at this point the real issue will require serious repairs that are beyond my skills (I don't know how to solder), but maybe I'm missing something simple.
