a running operating system can cause damage to your data or system. We recommend to 

always shut down the system properly from the operating system.

Ensure that a USB mouse is connected to your motherboard if you want to use the 

mouse to control the BIOS setup program.

If the system becomes unstable after changing any BIOS setting, load the default 

settings to ensure system compatibility and stability. Select the Load Optimized 

Defaults item under the Exit menu or press hotkey F5. See section 2.10 Exit Menu 

for details.

If the system fails to boot after changing any BIOS setting, try to clear the CMOS and 

reset the motherboard to the default value. See section 1.6 Jumpers for information 

on how to erase the RTC RAM.

The BIOS setup program can be used under two modes: EZ Mode and Advanced Mode. 

You can change modes from the Exit menu or from the Exit/Advanced Mode button in the EZ 

Mode/Advanced Mode screen.

By default, the EZ Mode screen appears when you enter the BIOS setup program. The EZ 

Mode provides you an overview of the basic system information, and allows you to select 

the display language, system performance mode and boot device priority. To access the 

Advanced Mode, click Exit/Advanced Mode or press F7 for the advanced BIOS settings.

The default screen for entering the BIOS setup program can be changed.
