Chapter 4: BIOS Setup
Installation
The BIOS is the basic input/output system, the firmware on motherboard
that enables your hardware to interface with your software. This chapter
describes different settings for the BIOS that can be used to configure
your system.
The BIOS section of this manual is subject to change without notice and
is provided for reference purposes only. The settings and configurations
of the BIOS are current at the time of print, and therefore may not match
exactly what is displayed on screen.
This section describes the BIOS setup program. The setup program lets
you modify basic configuration settings. The settings are then stored in a
dedicated, battery-backed memory (called NVRAM) that retains the
information when the power is turned off.
This motherboard’s BIOS is a customized version of the industry-
standard BIOS for IBM PC AT-compatible personal computers. The
BIOS provides critical, low-level support for the system’s central
processing unit (CPU), memory, and I/O subsystems.
This BIOS has been customized by adding important features such as
password protection, power management, and chipset “tuning” features
that control the system. This section will guide you through the process
of configuring the BIOS for your system setup.
Starting Setup
The BIOS is immediately activated when you turn on the computer. The
BIOS reads system configuration in CMOS RAM and begins the process
of checking out the system and configuring it through the Power-On-
Self-Test (POST).
When these preliminary tests are complete, the BIOS searches an
operating system on one of the system’s data storage devices (hard
drive, CD-ROM, etc). If one is found, the BIOS will launch that operating
system and hand control over to it. You can enter the BIOS setup by
pressing the [
Delete ] key when the machine boots up and begins to
show the memory count.
