I got this mobo without CPU/Dallas/Bios and almost all jumpers were missing.
I programmed bios P06Y034Q.PRD and put P90 cpu.
Unfortunately still not boot and any post code.
CPU is not warm so firstly would desolder SMP50N06 and check via multimeter?

Is that FET getting warm at all?
Here a simple guide:

Highscreen AT: Pentium 60@66 MHz
Highscreen ATX: Athlon Classic 1 GHz
I have a manual for this board and so I scanned it and created a entry here : http://www.win3x.org/uh19/motherboard/show/6225
I'll upload your image 😁

I checked via this: http://electronicsbeliever.com/how-to-know-if … t-is-defective/
and always got 0 on diode test. So probably is defective. Now worse job is finding replacement
// RFP50N06 is reasonable so will try with it
still on investigation.
Can someone take a pic of JP22 (below cpu and next to RTC) ? It is a resistor probably but don't know which value..

is there a resistor between 1 & 2 pin which what value?
I put 1.5kOhm resistor but didn't help 😀
Isn't PCI version compatible with P/F processors only? It is it only the other way around, that vlb boards are not?
Please use the "quote" option if asking questions to what I write - it will really up the chances of me noticing 😀
