Chapter 3: BIOS setup

• 

The BIOS setup screens shown in this section are for reference purposes only, and 

may not exactly match what you see on your screen.

• 

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 

Defaults item under the Exit menu or press hotkey <F5>. See sectionExit 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

switches 

for information on how to erase the RTC RAM via the Clear CMOS button.

• 

The BIOS setup program does not support the Bluetooth devices.

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 screen.

Use the BIOS Setup to update the BIOS or configure its parameters. The BIOS screen 

include navigation keys and brief onscreen help to guide you in using the BIOS Setup 

program.

To enter BIOS Setup at startup, press <Delete> during the Power-On Self Test (POST). If you 

do not press <Delete>, POST continues with its routines.

To enter BIOS Setup after POST:

• 

Press <Ctrl>+<Alt>+<Delete> simultaneously.

• 

Press the reset button on the system chassis.

• 

Press the power button to turn the system off then back on. Do this option only if you 

failed to enter BIOS Setup using the first two options.

After doing either of the three options, press <Delete> key to enter BIOS.
