Entering the BIOS Setup
BIOS (Basic Input and Output System) stores system hardware settings that are needed for
system startup in the Desktop PC.
In normal circumstances, the default BIOS settings apply to most conditions to ensure
optimal performance. Do not change the default BIOS settings except in the following
circumstances:
• An error message appears on the screen during the system bootup and requests you
to run the BIOS Setup.
• You have installed a new system component that requires further BIOS settings or
update.
Inappropriate BIOS settings may result to instability or boot failure. We strongly recommend
that you change the BIOS settings only with the help of a trained service personnel.

8.1 boot time is quite fast, so we developed the following ways for you to quickly
access the BIOS:
• Press the power button for at least four seconds to shut down your Desktop PC, then
press the power button again to turn your Desktop PC back on, and press <Del> during
POST.
• When your Desktop PC is off, disconnect the power cord from your Desktop PC’s
power connector. Reconnect the power cord and press the power button to turn on your
Desktop PC. Press <Del> during POST.
POST (Power-On Self Test) is a series of software controlled diagnostic tests that run when
you turn on your Desktop PC.
