So here is the story, the very same board I done the comparison between different chipsets here or the fight against the abit here has gone nuts.
Literally I put it in a box 2 days ago, I took out before to do a comparison between different Riva 128zx cards and that was happened:
Initally the ps2 keyboard didn't get detected so it hanged up in the bios.
I tried to connect and disconnect it several time and I ended up connected a usb keyboard which worked fine (for a couple of reboots), I was able to modify some bios settings and also boot to dos.
I tried to: swap memory, swap cpus, reflash the bios, reset the bios settings.
My idea is that if there is a ps2 mouse or keyboard connected it just goes nuts. It does to a less extent if I use the usb keyboard, but I noticed that it automatically enable caps lock or scroll lock and if I try to disable them from the keyboard it starts to beep and stop responding, then after a couple of seconds it starts to get good again.

Edit: Ok i'm so pissed off now... I found what the problem IS... this cheap chinese thing I used without issues since today:
And guess what? It killed another motherboard!
I was running the benchmarks in dos when the computer hanged up. It didn't boot for several time, when it came back to life, the memory count is now silly slow, it gives 16mb, then bios stop, then another 16mb and also on this mainboard the ps2 keyboard doesn't work anymore.
Now i'm really pissed off
Here is the problem with the killed BX Master: https://youtube.com/shorts/7PIG4lBFLhA
