Hello,
I recently pulled a motherboard out of a ARCHE RIVAL 286 case. There are no manufacturer markings to indicate who made the motherboard. The only clues are PAT-7.2A and Y-7.2 printed in a corner and in the middle of the ISA slots, respectively. Also has an ARCHE sticker on the board. CHIPS is the chipset used on this board. The board does not post at the moment, otherwise I'd see what was at the bottom of the POST screen. The award bios doesn't have any clues but I did save the .bin files. I have to solder in a socket and insert the keyboard IC...maybe after than the board will post. I have replaced virtually all the caps on this board. Pics attached.
