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 Intel Pentium ®4 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. This AWARD BIOS
can manage power to the hard disk drives and video monitors.
ACPI Support
Award ACPI BIOS support Version 1.0 of Advanced Configuration and
Power interface specification (ACPI). It provides ASL code for power
management and device configuration capabilities as defined in the
ACPI specification, developed by Microsoft, Intel and Toshiba.
PCI Bus Support
This AWARD BIOS also supports Version 2.1 of the Intel PCI
(Peripheral Component Interconnect) local bus specification.
