BIOS Setup
Introduction
This manual discussed Award™ Setup program built into the ROM BIOS. The Setup
program allows users to modify the basic system configuration. This special information
is then stored in battery-backed RAM so that it retains the Setup information when the
power is turned off.
The Award BIOS™ installed in your computer system’s ROM (Read Only Memory) is
a custom version of an industry standard BIOS. This means that it supports IntelTM
processors input/output system. The BIOS provides critical low-level support for
standard devices such as disk drives and serial and parallel ports.
Adding important has customized the Award BIOS™, but nonstandard, features such as
virus and password protection as well as special support for detailed fine-tuning of the
chipset controlling the entire system.
The rest of this manual is intended to guide you through the process of configuring your
system using Setup.
Plug and Play Support
These AWARD BIOS supports the Plug and Play Version 1.0A specification. ESCD
(Extended System Configuration Data) write is supported.
EPA Green PC Support
This AWARD BIOS supports Version 1.03 of the EPA Green PC specification.
APM Support
These 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 be managed by this
AWARD BIOS.

PCI Bus Support
This AWARD BIOS also supports Version 2.1 of the Intel PCI (Peripheral Component
Interconnect) local bus specification.
DRAM Support
SDRAM (Synchronous DRAM) are supported.
Supported CPUs
This AWARD BIOS supports the IntelTM CPU.

This submenu allows you to change CPU clock ratio.
(However, when you try to change different CPU clock ratio, you should check
your CPU frequency in advance. The CPU clock ratio should be changed
depending on your CPU frequency.)
Load Optimized Defaults
This selection allows you to reload the BIOS when the system is having
problems particularly with the boot sequence. These configurations are factory
settings optimized for this system. A confirmation message will be displayed
before defaults are set.
