Hi There,

Just found a board with Cx486DX2-50. No board model or information I could find. Maybe we can find here, when it is posted.

Possibly a A-Trend model due to Contaq and Sis chipset usage and similar board designs but not sure.

The board seems to have been added by one F. Sinan, that name seems familiar for some reason...

That board is nowhere, working flawlessly but trying to analyze the jumpers, found speed jumpers and cache and onboard cpu enable, disable.

Cpu identification jumpers are not easy, there is no similar board out there, manufactured by another company.

This is very strange that nobody could help on this boards jumper settings. Strange.
