I have my I/O board fixed and it booted 1 time yesterday, but now I'm getting the "connect I/O board" error at boot.
The I/O board has power and I also checked the serial cable and it's fine.
I'm guessing that the serial port on the PC went bad. Is there any way to verify that?
I don't have another motherboard to try.
