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

series of built-in diagnostics performed by the BIOS. After the POST routines are completed, the
following message appears:
