About the Setup Utility
The computer uses the latest American Megatrends 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 configura-
tion 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.
