I'm getting the same error :/ What was the solution? I've tried resetting my BIOS.

This happened when I put in my newly replaced GF6800U after using a TNT2 m64 for a month.

BIOS says:
"CMOS Checksum Bad
CMOS Date/Time not set"

The batttery is there. The CMOS Reset jumpers are back at 1-2.

What to do?
