QuickīButtons
This motherboard has four quick buttons: Power, Reset, Clear CMOS, and Clear Battery. 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 the clear CMOS button to clear the
BIOS conīæguration and reset the CMOS values to factory defaults when needed. The Clear Battery button has
the same function as removing the battery from the motherboard.
