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> or <F2> during the Power‑On Self Test (POST). If you do not press <Delete>

or <F2>, POST continues with its routines.

Entering BIOS Setup after POST

To enter BIOS Setup after POST:

Press <Ctrl>+<Alt>+<Del> 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 rst two options.

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 you

always shut down the system properly from the operating system.
