2.2 BIOS setup program
Use the BIOS Setup program to update the BIOS or configure 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>+<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 first 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.
