1-8 Onboard Buttons, Switches and LEDs
Quick Buttons
This motherboard has 3 quick buttons: power button, reset button and clear 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 BIOS
configuration and reset the CMOS values to factory defaults when needed.

BIOS Switch and BIOS LED Indicators
The BIOS switch (BIOS_SW) allows users to easily select a different BIOS for boot up or overclocking, helping to
