What is clearing CMOS? And what does it do?

Since i only have this PC, alot of people say clearing the Cmos helps alot. I know its the battery, but can someone tell me the steps and what happens after? Does the Bios get cleared or something?

If your PC runs fine, you don't need to clear your CMOS. It's only when a overclock attempt goes bad and your computer no longer boots. It's to reset all the settings that you changed in the bios when overclocking.

the most important thing it does is to clear & rebuild the dmi pool see building DMI pool for what dmi is. overclocking or similar mishaps can cause the dmi pool to become corrupt.

when your cmos needs resetting you,ll know it,till then don,t worry about.

i had to reset one today(beep,beep ,beep,"cpu was unworkable"(no getting into bios to fix)xp2500-1800mhz running 1100mhz during this.

unplug psu,swap cmos jumper for abit,swap back ,plug in,power up get your butt into the bios.

most if not all my cmos clears are oc,s too far(a tiny few because of swapping diff chips)
