Jumper

1. Clear RTC RAM (CLRTC_SW)
This jumper allows you to enable the clr CMOS switch. You can clear the CMOS

memory of date, time, and system setup parameters by erasing the CMOS RTC

RAM data. The clr CMOS switch on the back I/O helps you easily to clear the

system setup information such as system passwords.
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Press down the clr CMOS switch.
3. Plug the power cord and turn ON the computer.
4. Hold down the key during the boot process and enter BIOS setup to

re-enter data.

Removing the cap will cause system boot failure!

• The clr CMOS switch will not function if the jumper cap on CLRTC_SW is

moved to the Disable position, but the shutdwon function in S0 mode (DOS

mode) still works.

• Make sure to re-enter your previous BIOS settings after you clear the

CMOS.

• You do not need to clear the RTC when the system hangs due to CPU

overclocking. With the C.P.R. (CPU Parameter Recall) feature, shut down

and reboot the system so the BIOS can automatically reset CPU parameter

settings to default values. If the system hangs due to overclocking of

memory timing or chipset voltage and the power button fails to function,

pressing down the clr CMOS switch will shut down the system and clear

CMOS simultaneously.
