The board is running an Award BIOS and all I can get from the post analyzer card is CF then EF. The button cell battery is above 3 volts. There are no beep codes. There …

Ugh, may have to do this the hard way. Look up the IO chip and find pinout, continuity check to the connector, then check those relays for their singals for the vga switching, check sound card, find pins, not going to be easy.

Since multiple motherboards are talked about in this thread let it be known, 486 you need one 72 pin simm or 4 30 pin simms to complete the bus width With pentium eg socket 4, 5, 7, ss7 You need 1 dimm, two 72 pin simm, or 8 30 pin simm to populate the bus width Note: If I recall correctly, there …

Are there any good easy guides out there for how to do this ? or even a program that will do it automatically or image files, etc.? I think it would be really cool to be rocking windows 98 visually but actually 11 under the hood

If you have a donor north bridge you might try a transplant.

Those graphs very unusual I kind of suspect that you might have damaged your North Bridge. I believe you said you tried other CPUs, and had the same result I hate to say it, but my hunch is that you have damaged silicone on that board. You can of course continue testing. I may be incorrect, but at …

Pull all cards, go minimal with different cards. I’m going to assume turbo button isn’t functional, but you could try a jumper on the pins (though that probably isn’t it) Try a benchmarking comparison like speedsys. Are the benchmarks also lower? Pull that cf card out. Bull the floppy cable out.

Never bypass pullups/pulldowns like that if what was done is what I think was done. There is an example of someone doing this in the tillamook thread, I had to fix the procedure for them lol. Anyway, following their method it sometimes blows up a resistor. Ah, I'd wondered if there might be a …

Lol Cache interposers might be possible. Still waiting for someone to check what’s going on with the jumpers on the non plus might be 512k hiding there… (doubt it)
