Got this cool socket 7 board a while ago but I can't seem to get it to work. I got this as a complete system with case and matching PSU. It's a very unusual small form factor. The board reads MB-5BLTP, which is a type I cannot find anywhere online. There's this Russian site where someone looked for info on the BLPT-2 variant, but apart from that this is a very unknown system. From what I could research, it's a late era socket 7 (from 1998) and has a i430TX chipset . It came with a 200MMX. I could use some pointers on what to try next:

I've inspected the board for damage but it seems clean. The only odd part is this bodge wire that looks very much done by the factory. The wire seems to connect the VGA chip to a jumper. There's one cut trace and a resistor soldered.

Stuff I've tried so far:
- Verify that the CPU is working (in a different system)
- Verify that the RAM is working (in a different system)
- Check voltages on PSU rails (ok!)
- Check voltages on vcc2 and vcc3 (ok!)
- Put in post analyzer card (no post codes or beeps whatsoever)
- Try various jumper settings across the board (doesn't help)
- Check the contents of the BIOS chip (seems good)
- Check the RAM voltage (is ok, 3.3v)

I've touched all chips to see if any of them stand out when it comes to heat. Most of them just get a little warm. The most heat seems to come from this network chip, which seems odd. It's not burning my finger but certainly hotter than the other chips. Not sure if this is reason enough to take it off the board entirely. I think it should do at least some kind of posting even with a bad network chip?

Any idea's on what to do/try/check next? Could really use some help and guidance to get this baby working again 😀
