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

DDR DRAM are supported.

Supported CPUs

This AWARD BIOS supports the IntelTM CPU.
