Please, does anyone knows model of this mainboard?

It's Socket 3, 486 motherboard, from manufacturer Informtech Industrial. I don't know model and can't properly set jumpers.

Works with 486 AMD DX 40 MHz. Also with IBM DX4 100 MHz but shows IBM CPU as DX2 100 MHz. Both are 5V CPUs. I'm afraid to try any 3V CPU at this moment because I don't know how to set jumpers. Need manual or at least exact model.

Tell us what is the POST string (the string found at the bottom of the screen where the bios counts the ram), it often helps

Not very helpful, so your best bet is trying to find your board in TH99:
