Chapter 4: BIOS Setup

4.2 BIOS Setup program

This motherboard supports a programmable firmware chip that you can
update using the provided utility described in section “4.1 Managing and
updating your BIOS.”

Use the BIOS Setup program when you are installing a motherboard,
reconfiguring your system, or prompted to “Run Setup”. This section
explains how to configure your system using this utility.

Even if you are not prompted to use the Setup program, you may want to
change the configuration of your computer in the future. For example, you
may want to enable the security password feature or change the power
management settings. This requires you to reconfigure your system using
the BIOS Setup program so that the computer can recognize these
changes and record them in the CMOS RAM of the firmware hub.

The firmware hub on the motherboard stores the Setup utility. When you
start up the computer, the system provides you with the opportunity to run
this program. Press <Delete> during the Power-On Self Test (POST) to
enter the Setup utility. Otherwise, POST continues with its test routines.

If you wish to enter Setup after POST, restart the system by pressing
<Ctrl> + <Alt> + <Delete>, or by pressing the reset button on the system
chassis. You can also restart by turning the system off and then back on.
Do this last option only if the first two failed.

The Setup program is designed to make it as easy to use as possible. It is
a menu-driven program, which means you can scroll through the various
sub-menus and make your selections from the available options using the
navigation keys.

The default BIOS settings for this motherboard apply for 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 Default
Settings item under the Exit Menu. See section “4.7 Exit Menu.”

The BIOS setup screens shown in this chapter are for reference
purposes only, and may not exactly match what you see on your
screen.
