BIOS Setup Utility
BIOS Setup Utility is a program for configuring the BIOS (Basic Input/Output System) settings
of the computer.
BIOS is a layer of software called firmware that translates instructions from other layers of
software into instructions that the computer hardware can understand. The BIOS settings are
needed by your computer to identify the types of installed devices and establish special
features.
This chapter tells you how to use the BIOS Setup Utility.
When to Use the BIOS Setup Utility
You need to run the BIOS Setup Utility when:

• You want to modify some specific settings of the hardware.
• You want to modify some specific settings to optimize system performance.
To run BIOS setup, press the <Delete> key immediately when the system boots. The startup
