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
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. Power to the
hard disk drives and video monitors can be managed by this AWARD BIOS.

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.

By Choosing “Auto (ESCD)” (default), the system BIOS will detect the
system resources and automatical ly assign the relative IRQ and DMA
channel for each peripheral. By Choosing “Manual”, the user will need to
assign IRQ & DMA for add-on cards. Be sure t hat there are no IRQ/DMA
and I/O port conflicts.

7.3 IRQ RESOURCES

This submenu will allow you to assign each system interrupt a type,
depending on the type of device using the interrupt. When you press the
“Press Enter” tag, you will be directed to a submenu that will allow you to
configure the system interrupts. This is only configurable when
“Resources Controlled By” is set to “M anual”.
IRQ-3 assigned to PCI Device
IRQ-4 assigned to PCI Device
IRQ-5 assigned to PCI Device
IRQ-7 assigned to PCI Device
IRQ-9 assigned to PCI Device
IRQ-10 assigned to PCI Device
IRQ-11 assigned to PCI Device
IRQ-12 assigned to PCI Device
IRQ-14 assigned to PCI Device
IRQ-15 assigned to PCI Device

7.4 PCI / VGA PALETTE SNOOP

Choose Disabled or Enabled. Some graphic controllers that are not VGA
compatible take the output from a VGA controller and map it to their
display as a way to provide boot information and VGA compatibility.
However, the color information coming from the VGA controller is drawn
from the palette table inside the VGA controller to generate the proper
colors, and the graphic controller needs to know what is in the palette of
the VGA controller. To do this, the non-VGA graphic controller watch for
the Write access to the VGA palet te and registers the snoop data. In PCI
based systems, where the VGA controller is on the PCI bus and a
non-VGA graphic controller is on an ISA bus, the Write Access to the
palette will not show up on the ISA bus if the PCI VGA controller responds
to the Write.
In this case, the PCI VGA controller should not respond to the Write, it
should only snoop the data and permit the access to be forwarded to the
ISA bus. The non-VGA ISA graphic controller can then snoop the data on
the ISA bus. Unless you have the above situation, you should disable
this option.
Disabled (default) disable the function.
Enabled Enable the function.

9.6 CPU CLOCK

This item allows you to select CPU Clock, and CPU over clocking.

Special Notice:

If unfortunately, the system’s frequency that you are selected is not
functioning, there are two methods of booting-up the system.

Method 1:

Clear the COMS data by setting the JCOMS1 ((2-3) closed)) as “ON”
status. All the CMOS data will be loaded as defaults setting.

Method 2:

Press the <Insert> key and Power button simultaneously, after that
keep-on pressing the <Insert> key until the power-on screen showed.

This action will boot-up the system according to FSB of the processor

.

It’s strongly recommended to set CPU Vcore and clock in default setting. If the
CPU Vcore and clock are not in default setting, it may cause CPU or M/B damage.
