I don't find those POST cards much good because I can rarely interpret the answer.
Also the code is specific to the type of BIOS you have, which you don't know.
Anyway, c1 can be:
Award - memory presence test; OEM specific test to size onboard memory. Bad SIMM
Chip & Tech - I/O channel activated
Ami - NMI is disabled. Power on delay started
Phoenix - Initialize error logging.
The name of the BIOS is normally written on the BIOS chip - you'll need to check it, but unless it's Award, I can't interpret the problem.
Also if the code was 1C NOT C1 the error is different......
Have you read through this?
