2.6 Jumper
Clear RTC RAM (3-pin CLRTC_SW)
This jumper allows you to enable the clr CMOS switch on the back I/O. You can
clear the CMOS memory and system setup parameters by erasing the CMOS RTC
RAM data. The clr CMOS switch on the back I/O helps you easily clear the system
setup information such as system passwords.
To erase the RTC RAM:
1. Press down the clr CMOS switch on the back I/O.
2. Hold down the key during the boot process and enter BIOS setup to
re-enter data.

*G3: Power off without +5VSB power (AC power loss); S5: Power off with +5VSB power
**The system shuts dowm immediately.
• The clr CMOS switch will not function if the CLRTC_SW jumper is moved
to the Disable position, but the shutdwon function in S0 mode (DOS mode)
still works.
• Ensure 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.
