BIOS Setup Utility is a program for configuring the computer's BIOS (Basic Input/Output System) settings. BIOS is a software layer, also called firmware, that translates instructions from other software layers into instructions that the computer hardware can understand. BIOS settings are required by your computer to identify the types of devices installed and to set up special functions. This chapter tells you how to use the BIOS Setup utility.
