2.2 BIOS setup program
This motherboard supports a programmable firmware chip that you can update u sing the
provided utility described in section “2.1 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 sy stem
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 start 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+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 progr am is designed to make it as easy to use as possible. Bei ng 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.
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 “2.7 Exit Menu.”
The BIOS setup screens shown in this section are for reference
purposes
only, and may not exactly match what you see on
your screen.
