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.

“On” Means always set CMOS to the “On” statu s when AC power is lost
“Former-Sts” Means to maintain the last status of the CMOS when AC power is lost.
For example: If set to “Former-Sts” and AC power is lo st 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.

7 PnP/PCI Configurations

This section describes configuring the PCI bus system. PCI, or Personal Computer
Interconnect, is a system which allows I/O devices to operate at speeds nearing the speed of
the CPU itself uses when communicating with its own special components. This section
covers some very technical items and it is strongly recommended that only experienced
users should make any changes to the default settings.

Figure 7. PnP/PCI Configurations

!

7.1 PNP OS Installed

When set to YES, BIOS will only initialize the PnP cards used for the boot sequence (VGA,
IDE, SCSI). The rest of the cards will be initialized by the PnP operating system like
Window™ 95. When set to NO, BIOS will initialize all the PnP cards. For non-PnP
operating systems (DOS, Netware™), this option must set to NO.

The Choices: No (default), Yes.

7.2 Reset Configuration Data

The system BIOS supports the PnP feature which requires the system to record which
resources are assigned and protects resources from conflict. Every peripheral device has a
node, which is called ESCD. This node records which resources are assigned to it. The
system needs to record and update ESCD to the memory locations. These locations (4K)
are reserved in the system BIOS . If the Disabled (default) option is ch osen, the system‘s
ESCD will update only when the new configuration varies from the last one. If the Enabled
option is chosen, the system is forced to update ESCDs and then is automatically set to the
“Disabled” mode.

The above settings will be shown on the screen only if “Manual” is chosen for the resources
controlled by function.

33

P4M80-M7 BIOS Manual

Legacy is the term, which signifies that a resource is assigned to the ISA Bus and provides
non-PnP ISA add-on cards. PCI / ISA PnP sign ifies that a resource is assigned to the PCI
Bus or provides for ISA PnP add-on cards and peripherals.

The Choices: Disabled (default), Enabled.

7.3 Resources Controlled By

By Choosing “Auto(ESCD)” (default), the system BIOS will detect the system resources
and automatically 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
that there are no IRQ/DMA and I/O port conflicts.

7.4 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 “Manual ”.

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

7.5 PCI / VGA Palette Snoop

Choose Disabled or Enabled. Some graphic controllers which 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 contro ller to generate the proper colors, and the graphic co ntroller
needs to know what is in the palette of the VGA controller. To do this, the non-VGA
graphic controller watches for the Write access to the VGA palette 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 bu s. The non -VGA ISA graph ic
controller can then snoop the data on the ISA bus. Unless you have the above situation,
you should disable this option.

Disabled (default) Disables the function.
Enabled Enables the function.

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 da mag e.
