2 BIOS Setup
This chapter tells how to change
the system settings through the
BIOS setup menus. Detailed
descriptions of the BIOS parameters are also provided.
2.1 BIOS Setup Program
This motherboard supports a programmable firmware chip that you can update using
the provided utility. 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 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 program is designed to make it as easy to use as possible. Being a menudriven program, it lets you scroll through the various sub-menus and make your
selections from the available options using the navigation keys.
Note!
!
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 Optimized Defaults from the BIOS menu screen.
!
The BIOS setup screens shown in this section are for reference
purposes only, and may not exactly match what you see on your
screen.
