What is a CMOS Checksum error?

[rigmah]

I just got one of these and i have no idea where is came from.

It usually results from incorrectly configured CMOS settings, reboot if you get it again, go into the bios, restore to defaults and clear everything. If you get that again, reflash the BIOS. But yeah I've gotten this error before, right after I flashed my BIOS, set up my custom settings and the error went away.

if it just came out of nowhere, you may have a dying battery, or a power dip hit while you were booting
