BIOS SETUP BIOS Setup This chapter describes the different settings available in the Award BIOS that comes with the board. The topics covered in this chapter are as follows: BIOS Introduction ................ 22 BIOS Setup ................... 22 Standard CMOS Setup ..............24 Advanced BIOS Features .............
BIOS Introduction The Award BIOS (Basic Input/Output System) installed in your computer system’s ROM supports Intel/AMD processors. The BIOS provides critical low-level support for a standard device such as disk drives, serial ports and parallel ports. It also adds virus and password protection as well as special support for detailed fine-tuning of the chipset controlling the entire system.

BIOS SETUP Standard CMOS Setup “Standard CMOS Setup” choice allows you to record some basic hardware configurations in your computer system and set the system clock and error handling. If the motherboard is already installed in a working system, you will not need to select this option. You will need to run the Standard CMOS option, however, if you change your system hardware configurations, the onboard battery fails, or the configuration stored in the CMOS memory was lost or damaged.
