View Full Version : PS/2 model 50 80287 coprocessor installation

Hi all,
I'm having some trouble getting my PS/2 to recognize the 80287 coprocessor that is installed. The reference software doesn't recognize it when I do an automatic configuration and manual configuration won't let me select it either. I'm not sure if I'm doing something wrong (maybe need extra files for the ref disk?) or if maybe the chip is dead?
Does anyone have any advice?
