4.16.2 Clearing or changing passwords
Clear RTC RAM (2-pin CLRTC)
This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can clear the CMOS memory of date, time, and system
setup parameters by erasing the CMOS RTC RAM data. The onboard button cell battery powers the RAM data in CMOS, which include
system setup information such as system passwords.
To erase the RTC RAM :
1.
Turn OFF the computer and unplug the power cord.
2.
Use a metal object such as a screwdriver to short the two pins.
3.
Plug the power cord and turn ON the computer.
4.
Hold down the <
Del
> key during the boot process and enter BIOS setup to reenter data.
Except when clearing the RTC RAM, never short the pins on CLRTC header. Shorting the pins will cause system boot failure!
