Chapter 3 - BIOS Settings
X Overview
The BIOS is a program that takes care of the basic level of communication between the CPU
and peripherals. It contains codes for various advanced features found in this system board.
The BIOS allows you to configure the system and save the configuration in a battery-backed
CMOS so that the data retains even when the power is off. In general, the information stored
in the CMOS RAM of the EEPROM will stay unchanged unless a configuration change has been
made such as a hard drive replaced or a device added.
It is possible that the CMOS battery will fail causing CMOS data loss. If this happens, you need
to install a new CMOS battery and reconfigure the BIOS settings.
Note:
The BIOS is constantly updated to improve the performance of the system board;
therefore the BIOS screens in this chapter may not appear the same as the actual
one. These screens are for reference purpose only.
Default Configuration
Most of the configuration settings are either predefined according to the Load Optimal Defaults
settings which are stored in the BIOS or are automatically detected and configured without re-
quiring any actions. There are a few settings that you may need to change depending on your
system configuration.
Entering the BIOS Setup Utility
The BIOS Setup Utility can only be operated from the keyboard and all commands are keyboard
commands. The commands are available at the right side of each setup screen.
The BIOS Setup Utility does not require an operating system to run. After you power up the
system, the BIOS message appears on the screen and the memory count begins. After the
memory test, the message "Press DEL to run setup" will appear on the screen. If the message
disappears before you respond, restart the system or press the "Reset" button. You may also
restart the system by pressing the <Ctrl> <Alt> and <Del> keys simultaneously.
