2.2 BIOS setup program
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:

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

Using the power button, reset button, or the <Ctrl>+<Alt>+<Del> keys to force reset from a

always shut down the system properly from the operating system.
