2.6 Slide switch
1. Clear RTC RAM (3-pin 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. Press down the clr CMOS switch on the back I/O.
2. Hold down the <Del> key during the boot process and enter BIOS setup
to re-enter data.

**
• TheThe
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.
*G3: Power off without +5VSB power (AC power loss); S5: Power off with +5VSB power
**The system shuts dowm immediately.
