About the Setup Utility
The computer uses the latest Award BIOS (Basic Input and Output System) with support for
Windows Plug and Play. The CMOS chip on the main board contains the ROM setup instructions
for configuring the main board BIOS.
The BIOS 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 have 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.
