C.P.R. (CPU Parameter Recall)
The C.P.R. feature of the motherboard BIOS allows automatic re-setting to the
BIOS default settings in case the system hangs due to overclocking. When the
system hangs due to overclocking, C.P.R. eliminates the need to open the system
chassis and clear the RTC data. Simply shut down and reboot the system, and the
BIOS automatically restores the CPU default setting for each parameter.

Onboard LED
The motherboard comes with a standby power LED. The green LED lights up
to indicate that the system is ON, in sleep mode, or in soft-off mode. This is a
reminder that you should shut down the system and unplug the power cable
before removing or plugging in any motherboard component. The illustration
below shows the location of the onboard LED.
2.1 Before you proceed
Take note of the following precautions before you install motherboard components
or change any motherboard settings.
• Unplug the power cord from the wall socket before touching any
component.
• Use a grounded wrist strap or touch a safely grounded object or to
a metal object, such as the power supply case, before handling
components to avoid damaging them due to static electricity.
• Hold components by the edges to avoid touching the ICs on them.
• Whenever you uninstall any component, place it on a grounded
antistatic pad or in the bag that came with the component.
• Before you install or remove any component, ensure
that the ATX power supply is switched off or the power cord is detached
from the power supply. Failure to do so may cause severe damage to the
motherboard, peripherals, and/or components.
