I recently installed a Shuttle Hot 555A Motherboard and upon boot up I received a CMOS Checksum error, CMOS Battery low. I subsiquently replaced the battry , but continue to get the error along with the clock resets to12:00. Prior to replacing the motherboard, I was wondering if the CMOS could corrupt and cause this issue and if there was a fix(IE Bios flash, or replacement of the bios chip. I was wondering also what pin the battry suppied voltage to and what was the volatge. Alteast I could rule out the motherboard.
