Well...not sure what you're talking about but clearing the CMOS can either be done by a switch (if your motherboard has one), or by pins. Usually you'd short pins 2 and 3 to clear cmos. 1 and 2 would be default. Pins are located on your motherboard.

Turn off all power
1) take your pin blocker and block off pins 2 and 3.
wait 15 seconds
2) Put the pin blocker back to on pin 1 and 2.

your cmos should be cleared.

Not sure what you're asking so I gave you this.
 
I think you mean BIOS.
If you want to get in that, turn the computer on and watch the screen. Itl tell you which button to hit to get into BIOS (before windows boots), reset the machine and spam that key till your in. Usually its DEL, but its different for every motherboard.
