3.2 BIOS Setup Program
This motherboard supports a programmable firmware chip that you can update using the provided
utility described in section “3.1 Managing and updating your BIOS.”
Use the BIOS Setup program w hen 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 can change the configuration of your
computer in the future. For example, you can 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 st art up the computer ,
the system provides you with the opportunity to run this program.
Press <Del> 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+Delet e>, 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. Being a menu-driven
program, it lets you scroll through the various sub-menus and make your selections from the
available options using the navigation keys.
z The default BIOS setti ngs for this motherboard apply for most
conditions to ensure optimum performance. If the syste m
becomes unstable af ter changing any BIOS settings, load the
default settings to ensure system comp atibility and st ability.
Select the Load Default Settings item under the Exit Menu.
See section “3.7 Exit Menu.”
z The BIOS setup screens shown in this section are for reference
purposes only , and may not exactly match what you see on
your screen.
