BIOS Setup
Introduction
This manual discussed Phoenix-Award™ Setup programbuilt 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 thepower 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 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 thePhoenix-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 ofthis manual is intended to guide you through the process ofconfiguring your
systemusing Setup.
Plug and Play Support
These PHOENIX-AWARD BIOS supports thePlug and Play Version 1.0A specification.
ESCD (Extended SystemConfiguration Data) writeis supported.
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
SystemManagement 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 BIOSsupport Version 1.0b ofAdvanced 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.
