I think I am reading the hard drive ok, dos loads OK and the dx-32 loads until it tries to load the BMDC. I never received the original software floppys with this machine so I can't try to boot from the floppy drive. If I put a non-system disk in the floppy drive, I get the standard message "Non-system disk" so I believe the floppy is also reading ok. I Think I will just pickup another motherboard and see what happens, unless anyone has any other ideas. I'll try to get a board that I can still get some documentation on so troubleshooting will be a little easier. How important is it to stay under P133 or will any board with ISA slots be OK? Thanks Fred
