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.

PWRON After PWR-Fail
This field determines the action the system will automatically take when power is restored
to a system that had lost power previously without any subsequent manual intervention.
There are 3 sources that provide current to the CMOS area that retains these Power-On
instructions; the motherboard battery (3V), the Power Supply (5VSB), and the Power
Supply (3.3V). While AC is not supplying power, the motherboard uses the motherboard
battery (3V). If AC power is supplied and the Power Supply is not turned on, 5VSB from
the Power Supply is used. When the Power Supply is eventually turned on 3.3V from the
Power Supply will be used.
There are 3 options: “Former-Sts”, “On”, “Off”.
“Former-Sts”Means to maintain the last status of the CMOS when AC
power is lost.
“On” Means always set CMOS to the “On” status when AC
power is lost
“Off” (default) Means always set CMOS to the “Off” status when AC
power is lost.
For example: If set to “Former-Sts” and AC power is lost when system is live, then after
AC power is restored, the system will automatically power on. If AC power is lost when
system is not live, system will remain powered off.
