Onboard Buttons, Switches and LEDs
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
reduce BIOS failure during overclocking. The SB switch allows enabling or disabling of the Dual BIOS function.
The LED indicator (MBIOS_LED/BBIOS_LED) shows which BIOS is active.
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 the clear CMOS button to clear
the BIOS configuration and reset the CMOS values to factory defaults when needed.
•
Always turn off your computer and unplug the power cord from the power outlet before clearing
the CMOS values.
•
Do not use the clear CMOS button when the system is on, or the system may shutdown and
data loss or damage may occur.
•
After system restart, go to BIOS Setup to load factory defaults (select Load Optimized Defaults) or
manually configure the BIOS settings (refer to Chapter 2, "BIOS Setup," for BIOS configurations).
