based ash utility. See pages 2-8 and 2-38 for details.
C.P.R. (CPU Parameter Recall)
When the system hangs due to overclocking failure, there is no need to open the
case to clear CMOS data. Just simply restart the system, the BIOS would show the
previous setting and then users can amend the CPU setting again. See page 1-26
for details.

ASUS M3A78-EMH HDMI 1-7
Onboard LED
The motherboard comes with a standby power LED that 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.
1.4 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 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.
