Quick Buttons
This motherboard has 3 quick buttons: power button, reset button and clearing CMOS button. The power button
and reset button allow users to quickly turn on/off or reset the computer in an open-case environment when they
want to change hardware components or conduct hardware testing. Use this button to clear the CMOS values
(e.g. date information and BIOS configurations) and reset the CMOS values to factory defaults when needed.

Clear CMOS Button
Always turn off your computer and unplug the power cord from the power outlet before clearing
•
the CMOS values.
After system restart, go to BIOS Setup to load factory defaults (select
•

Defaults
) or manually configure the BIOS settings (refer to Chapter 2, "BIOS Setup," for BIOS
configurations).
