Asrock 4coredual-VSTA bios issues

[mastron21]

I am running the motherboard with an E5200 processor and it is working wonderfully but everytime I reboot it tells me that the CMOS checksum bad.... any idea how I can fix this?

remove bios battery
switch cmos jumper
wait ~10 min
switch jumper back
reinstall battery

Basically, the checksum error means the settings are corrupted. How the bios deals with this is its own business, some revert to 'safe' settings. It could be just in need of a reset, perhaps some cmos setting your machine doesn't like (i.e. ram timings), or the battery is dead.

Well I tried that yesterday and got no results. battery works and is not dead...

Enter BIOS, Load BIOS Defaults, Save and Exit. Reboot, enter BIOS, then make any custom changes to BIOS options, Save and Exit.
