Use the BIOS Setup program to update the BIOS or congure its parameters. The BIOS
screens include navigation keys and brief online help to guide you in using the BIOS Setup
program.
Entering BIOS Setup at startup
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.
Entering BIOS Setup after POST
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

Using the power button, reset button, or the <Ctrl>+<Alt>+<Del> keys to force
reset from a running operating system can cause damage to your data or system. We
recommend that you always shut down the system properly from the operating system.
• The default BIOS settings for this motherboard apply to most conditions to ensure
optimum performance. If the system becomes unstable after changing any BIOS
settings, load the default settings to ensure system compatibility and stability. Select the
Load Setup Defaults item under the Exit menu. See section 2.9 Exit Menu.
