BIOS Setup
Introduction
This manual discussed Phoenix-Award™ Setup program built into the ROM BIOS. The
Setup program allows users to modify the basic system configuration. This special
informat ion is then stored in battery-backed RAM so that it retains the Setup information
when the power is turned off.
The Phoenix-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 P entium ® 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 Phoenix-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 PHOENIX-AWARD BIOS supports the Plug and Play Version 1.0A specification.
EPA Green PC Support
This PHOENIX-AWARD BIOS supports Version 1.03 of the EPA Green PC specification.
APM Support
These 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 be managed by this
PHOENIX-AWARD BIOS.
ACPI Support
Phoenix-Award ACPI BIOS support Version 1.0b 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.
