BIOS Setup
Introduction
The purpose of this manual is to describe the settings in the Phoenix-Award™
BIOS Setup program on this motherboard. The Setup program allows users to
mod ify the bas ic s ystem configuration and save these settings to CMOS RAM.
The power of CMOS RAM is supplied by a battery so that it retains the Setup
information when the po wer is turned off.
Basic Input-Output System (BIOS) determines what a computer can do without
accessing programs from a disk. This system controls most of the input and
output devices such as keybo ard, mouse, s erial ports and dis k drives. BIOS
activates at the first stage of the booting proc ess, loading and executing the
operating system. Some additional features, such as virus and password
protection or chipset fine-tuning options are also included in BIOS.
The rest of this manual will to guide you through the options and settings in
BIOS Setup.
Plug and Play Support
This PHOENIX-AWARD BIOS supports the Plug and Play Version 1.0A
specification and ESCD (Extended System Configuration Data) write.
EPA Green PC Support
This PHOENIX-AWARD BIOS supports Version 1.03 of the EPA Green PC
specification.
APM Support
This PHOENIX-AWARD BIOS supports Version 1.1&1.2 of the Advanced
Power Management (APM) specification. Power management features are
implemented via the System Management Interrupt (SMI). Sleep and Suspend
power management modes are supported. Power to the hard disk drives and
video monitors can also be managed by this PHOENIX-AWARD BIOS.

Advanced BIOS Features
This submenu allows you to configure ad vanc ed features o f the BIOS.
Advanced Chipset Features
This submenu allows you to configure special chipset features.
Integrated Peripherals
This submenu allows you to configure certain IDE hard drive options and
Programmed Input/ Output features.
Power Management Setup
This submenu allows you to configure the power management features.
PnP/PCI Configurations
This submenu allows you to configure certain “Plug and Play” and PCI options.
PC Health Status
This submenu allows you to monito r the hardware of your s ystem.
Performance Booster Zone
This submenu allows you to change CPU Vcore Voltage and CPU/PCI clock.
(However, we suggest you to use the default setting. Changing the voltage and
cloc k improp erly may damage the CP U o r M/B!)
Load Optimized Defaults
This selection allows you to reload the BIOS when problem occurs during
system booting sequence. These configurations are factory settings optimized
for this s ystem. A confirmation message will be displayed before defaults are

the same way as the Supervisor Password. If the Supervisor Password is set and
the User Password is set, the “User” will only be able to view configurations but
will not be able to change them.
