System Utilities
About the Setup Utility
The computer uses the latest “American Megatrends Inc.” BIOS will support for Windows Plug and Play. The
CMOS chip on the motherboard contains the ROM setup instructions for configuring the motherboard BIOS.
The BIOS (Basic Input and Output System) Setup Utility displays the system’s configuration status and provides
you with options to set system parameters. The parameters are stored in battery-backed-up CMOS RAM that
saves this information when the power is turned off. When the system is turned back on, the system is configured
with the values you stored in CMOS.
The BIOS Setup Utility enables you to configure:
z Hard drives, diskette drives and peripherals
z Video display type and display options
z Password protection from unauthorized use
z Power Management features
The settings made in the Setup Utility affect how the computer performs. Before using the Setup Utility, ensure
that you understand the Setup Utility options.
This chapter provides explanations for Setup Utility options.
The Standard Configuration
A standard configuration has already been set in the Setup Utility. However, we recommend that you read this
chapter in case you need to make any changes in the future.
This Setup Utility should be used:
z when changing the system configuration
z when a configuration error is detected and you are prompted to make changes to the Setup
Utility
z when trying to resolve IRQ conflicts
z When making changes to the Power Management configuration
z when changing the password or making other changes to the Security Setup
Entering the Setup Utility
When you power on the system, BIOS enters the Power-On Self Test (POST) routines. POST is a series of
built-in diagnostics performed by the BIOS. After the POST routines are completed, the following message
appears:
The default BIOS setting for this motherboard applies for most conditions with optimum
performance. It is not suggested to change the default values in the BIOS setup and the
manufacture takes no responsibility to any damage caused by changing the BIOS
settings.

Updating the BIOS
You can download and install updated BIOS for this motherboard from the manufacturer’s Web site. New
BIOS provides support for new peripherals, improvements in performance, or fixes for known bugs. Install
new BIOS as follows:
1 Create a bootable system disk. (Refer to Windows online help for information on creating a
bootable system disk.)
2 Download the Flash Utility and new BIOS file from the manufacturer’s Web site. Copy these
files to the system diskette you created in Step 1.
3 Turn off your computer and insert the system diskette in your computer’s diskette drive. (You
might need to run the Setup Utility and change the boot priority items on the Advanced BIOS
Features Setup page, to force your computer to boot from the floppy diskette drive first.)
4 At the A:\ prompt, type the Flash Utility program name and the file name of the new bios and
then press <Enter>. Example: AMINF340.EXE 040706.ROM
5 When the installation is complete, remove the floppy diskette from the diskette drive and restart
your computer. If your motherboard has a Flash BIOS jumper, reset the jumper to protect the
newly installed BIOS from being overwritten. The computer will restart automatically.
Using BIOS
When you start the Setup Utility, the main menu appears. The main menu of the Setup Utility displays a list of
the options that are available. A highlight indicates which option is currently selected. Use the cursor arrow keys
to move the highlight to other options. When an option is highlighted, execute the option by pressing <Enter>.
Some options lead to pop-up dialog boxes that prompt you to verify that you wish to execute that option. Other
options lead to dialog boxes that prompt you for information.
Some options (marked with a triangle X ) lead to submenus that enable you to change the values for
the option. Use the cursor arrow keys to scroll through the items in the submenu.
In this manual, default values are enclosed in parenthesis. Submenu items are denoted by a triangle X
