4.1 About the Setup Utility
The computer uses the latest “American Megatrends Inc.” BIOS with 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:
• Hard drives, diskette drives and peripherals
• Video display type and display options
• Password protection from unauthorized use
• 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.
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:
1. The Standard Configuration
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:
2. Entering the Setup Utility
• when changing the system configuration
• when a configuration error is detected and you are prompted to make changes to the Setup
Utility
• when trying to resolve IRQ conflicts
• when making changes to the Power Management configuration
• when changing the password or making other changes to the Security Setup

4.2 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 )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 .
The default BIOS seng for this motherboard apply for most condions with opmum performance.
We do not suggest users change the default values in the BIOS setup and take no responsibility to
any damage caused by changing the BIOS sengs.

You can download and install updated BIOS for this motherboard from the manufacturer’s Website.
New BIOS provides support for new peripherals, improvements in performance, or fixes for known
bugs. Install new BIOS as follows
8. Updating the BIOS
1 If your motherboard has a BIOS protection jumper, change the setting to allow BIOS
flashing.
2 If your motherboard has an item called Firmware Write Protect in Advanced BIOS
features, disable it. (Firmware Write Protect prevents BIOS from being overwritten.)
3 Prepare a bootable device or create a bootable system disk. (Refer to Windows online
help for information on creating a bootable system disk.)
4 Download the Flash Utility and new BIOS file from the manufacturer’s Web site. Copy
these files to the bootable device.
5 Turn off your computer and insert the bootable device in your computer. (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 bootable device
first.)
6 At the C:\ or A:\ prompt, type the Flash Utility program name and the file name of the
new BIOS and then press <Enter>. Example: AFUDOS.EXE 040706.ROM
7 When the installation is complete, remove the bootable device from the computer 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.
