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 AMD®processor
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
DDR SDRAM (Double Data Rate Synchronous DRAM) are supported.
Supported CPUs
This AWARD BIOS supports the AMD®CPU.
