BIOS Upgrading Utility and Motherboard
Shield

BIOS Upgrading Utility—One Click is All it T akes!

We are proud to inform you that your new motherboard comes with a BIOS upgrading and
motherboard protection utility. This BIOS updating program makes BIOS updating easy , and
enhances the security and stability of systems built with your motherboard.

BIOS Upgrading Utility Features:

• Anti-Virus BIOS Protection – This motherboard comes with a new hardware monitoring
function that can prevent any unauthorized BIOS updating caused by viruses. Only
this BIOS upgrading utility can update the BIOS for this motherboard.

• BIOS Updating Confidence – Beyond preventing viruses, the BIOS upgrading utility
allows BIOS updating with confidence. In the past, any failure or incorrect operation
during BIOS updating could crash the whole system. Normally the user wouldn’t
have the capability to retrieve and reestablish the system, they could only return the
computer to the supplier for costly, time-consuming repairs. With the enhanced
security of this BIOS upgrading utility, users of this motherboard can completely
avoid these problems. No matter what happens during BIOS updating, the user’s
system can still boot from the floppy drive, allowing the updating command to be
executed again.

• One-Click, Online BIOS Updating – For users of Windows 9X/Me/2000/XP/NT 4.0,
the BIOS upgrading utility allows you to use an innovative online updating technology .
Just one click can detect the BIOS version of your system, download the latest
version, and execute all the updating commands automatically from the Internet.
Restarting the computer completes the BIOS updating. This feature should be very
handy for users who need to update BIOS repeatedly, especially MIS staff. The
online BIOS updating program is included on the drivers CD-ROM included in the box
with your motherboard. Following the step-by-step instructions, you can easily update
or backup your BIOS. (If you have a different OS, see “Chapter 4 BIOS Upgrade”
for your BIOS updating procedure.)

• Linear Overclocking – the BIOS upgrading utility also provides a linear overclocking
function. Users can fine-tune the Front Side Bus (FSB) by increasing or reducing it
by as little as 1.0MHz to find the optimum FSB setting for the system. Should the
FSB be set too high, the system can be returned to the default setting by pressing the
“INS” key.

1.1 Essential Handling Precautions

IMPORT ANT . Read this section before unpacking your motherboard!

••

• Power Supply

••

Be careful! Always ensure that the computer is disconnected from the power supply
when working on the motherboard and its components. On the motherboard are 2
LEDs. One is green and indicates that the power connector is attached and the
system is in Standby , with 5V of power active to the motherboard. The other is red
and indicates that the system is in Suspend Mode. Serious damage could occur if
you remove or install any components when the green LED is lit; while additionally ,
you could experience a nasty shock if you touch anything inside the case when the
red LED is lit.

• Static Electricity

Static electricity may cause damage to the delicate integrated circuit chips on your
motherboard. Before handling the motherboard outside of its protective packaging,
ensure that there is no static electric charge in your body . A static discharge strong
enough to damage computer components is not perceptible by a human. Observe
these precautions while handling the motherboard and other computer components:

1. If possible, wear an anti-static wrist strap connected to a natural earth ground.

2. Touch a grounded or anti-static surface, or a metal fixture such as a pipe or the
chassis of your system, before touching the motherboard.

3. When you have removed the motherboard from its anti-static packaging, try to
hold it only by the edges, without touching any components.

4. Avoid contacting the components on add-on cards, motherboards, and modules
with the gold-colored connectors which plug into the expansion slots.

5. Handle system components only by their mounting brackets.

6. Keep components which are not connected to the system in their anti-static
packaging whenever possible.

INTRODUCTION 2

••

• Battery Replacement

••

The battery which holds the system settings memory (CMOS RAM) on your
motherboard should not require replacement for at least five years, and probably
much longer. In picture 2.1, it is located near the lower edge of the motherboard.
Incorrect computer time and/or loss of time may indicate a weak motherboard battery .
Please replace your battery only with the same type, or a similar type recommended
by the battery manufacturer. If the battery is replaced incorrectly, there is a risk of
a short circuit or explosion. Used batteries should be disposed of in accordance with
the manufacturer’s instructions and local environmental regulations.

2.3 CPU (Central Processing Unit) Installation

All this point you should be familiar with the handling precautions; checked that you have all of the
necessary hardware for building your system; inspected the motherboard package contents
and, looked at the layout of the motherboard. This chapter will take you step-by-step through the
process of installing the different hardware devices onto your new motherboard.

Caution!

1. Remember to always make sure the system power is off before installing or
removing any devices. Check the Power Indicator LEDs on the motherboard
as shown in Figure 2.2 and described in Section 1.1.

2. Don’t forget the static electricity precautions. (See Section 1.1.)

3. Be careful! Incorrectly inserting hardware onto your motherboard can
permanently damage the motherboard.

The motherboard has a ZIF Socket 462 to house the CPU. A CPU fan is necessary to prevent
overheating. If no fan has been supplied with the CPU, purchase and install one before you turn
on your system.

Warning! CPUs generate tremendous heat while operating. Make sure to install
a CPU fan with enough heat-dissipation grease to completely cover the CPU die
before powering up the computer. Never run the processor without the heatsink
properly and firmly attached.

PERMANENT DAMAGE COULD RESUL T!

Please follow the steps below to install the CPU:

Step 1:

To install the CPU, first turn off your system and remove its cover. Locate the ZIF socket and
open it by first pulling the lever sideways away from the socket then upwards at a 90-degree
right angle. Insert the CPU in the correct direction, smear the heat-dissipation grease over the
CPU die, then put a CPU fan on to cover the face of the CPU. With the added weight of the CPU

HARDWARE INSTALLATION 8

(

)

fan, no force is required to insert the CPU into the socket. Once completely inserted, close the
socket’s lever while holding down the CPU. This locks the CPU into the socket.

Step 2:

Connect the CPU fan’s cable to the CPU-FAN connector indicated on the diagram below.
Ensure that the cable is connected correctly! It will be obvious which way it must fit.

2.9 Primary/Secondary IDE Connectors (T wo 40-pin IDE)

This motherboard supports two 40-pin IDE connectors marked as IDE1 (primary IDE channel)
and IDE2 (secondary IDE channel). Each channel supports two IDE devices, for a total of four
devices. Connect your Hard Disk Drive (HDD) (the main one if you are using more than one) to
the “Master” connector (at the end of the cable) and connect it to IDE1 (see important note
below). If your HDD supports UltraDMA/66/100, you must use an 80-wire cable, otherwise the
HDD won’t be able to reach this speed. If you intend to operate two IDE devices from the same
channel, one device must be set to “Master” mode, the other to “Slave” mode. Hard disk drives,
CD ROM drives and other IDE devices can be set as either “master” or “slave”, depending on
the device’s jumper settings. Please refer to the device’s user manual for more information.

NOTE: The connectors must be attached properly to the IDE channels. Ensure

that the red stripe on one edge of the ribbon cable (this may be faint and
could also be a dotted line) is the closest to PIN1 (on the left with the
motherboard as oriented in the picture below).

CHAPTER 3 BIOS SETUP

3.1 BIOS Setup

Award BIOS has a built-in Setup program that allows users to modify the basic system
configuration. This information is stored in CMOS RAM, so it can retain the Setup information
when the power is turned off. If the CMOS battery fails, these data will be lost. If that happens,
you must setup your configuration parameters again after replacing the battery . Refer to Section

1.1, Essential Handling Precautions for instructions on replacing the CMOS battery .

3.2 The Main Menu

As you turn on or reboot the system, the BIOS is immediately activated. It will read the system
configuration information, and check the system through the Power On Self T est (POST). During
the POST process, press the [Del] key , to enter the A ward BIOS Setup configuration system.
The following screen will appear:

25 BIOS SETUP

3.4 Advanced BIOS Features

The “Advanced BIOS Features” option allows you to improve your system performance, and
setup system features according to your preferences.

• Virus Warning

When this function is “Enabled”, you will receive a warning message if a program
(specifically , a virus) attempts to write to the boot sector or the partition table of the hard
disk drive. Y ou should then execute an anti-virus program. Keep in mind that this feature
protects the boot sector only, not the entire hard drive.

NOT E: Many disk diagnostic programs that access the boot sector table can

trigger the virus warning message. If you plan to run such a program, we
recommend that you first disable this virus warning.

• CPU Internal Cache/External Cache

Cache memory is additional memory that is much faster than conventional DRAM (system
memory). CPUs from 486-type and up contain internal cache memory . Most, but not all,
modern PCs have additional (external) cache memory . When the CPU requests data,
the system transfers the requested data from the main DRAM into cache memory for
even faster access by the CPU. The “External Cache” field may not appear if your
system does not have external cache memory .

BIOS SETUP 26

• CPU L2 Cache ECC Checking

Select “Enabled” to ensure that the data are accurate.

• Processor Number Feature

This function was designed with the internet in mind. Select “ Enabled” to make the
processor serial number serve as a means of identifying your system.

• Quick Power On Self Test

Select “Enabled” to reduce the amount of time required to run the POST. The Quick
POST skips certain steps. We recommend that you normally disable Quick POST. It is
better to find a problem during POST than to lose data during your work.

• First/Second/Third Boot Device; Boot Other Device

The original IBM PCs loaded the DOS operating system from drive A (floppy disk).
Therefore, IBM PC-compatible systems are designed to search for an operating system
first on drive A, and then on drive C (hard disk). However, the BIOS attempts to load the
operating system from the devices in the sequence selected in these fields. In addition to
the traditional drives A (“Floppy”) and C (“HDD-0”), options include: “HDD-1”, “HDD-2”,
“HDD-3”, “CDROM”, a “SCSI” hard drive, a “LS120” drive, a “ZIP100” drive and a “LAN”
drive. If your boot device is not included in the list, you can set the “Boot Other Device”
field to “Enabled”, and let the system detect the drive automatically.

• Swap Floppy Drive

This field is effective only in systems with two floppy drives. Selecting “Enabled” assigns
physical drive B to logical drive A, and physical drive A to logical drive B.

• Boot Up Floppy Seek

When you select “Enabled”, the BIOS tests (seeks) floppy drives to determine whether
they have 40 or 80 tracks. Only 360-KB floppy drives have 40 tracks; drives with 720KB,

1.2MB, and 1.44MB capacity all have 80 tracks.

• Boot Up NumLock Status

T oggle between “On” and “Off” to control the state of the NumLock key when the system
boots. When toggled “On”, the numeric keypad generates numbers instead of controlling
cursor operations.

27 BIOS SETUP

• Gate A20 Option

Choose “Fast” (default) or “Normal”. “Fast” allows RAM access above 1MB to use the
fast Gate A20 line.

• Typematic Rate Setting

When this function is “Disabled”, the following two items (T ypematic Rate and Typematic
Delay) are irrelevant, and keystrokes repeat at a rate determined by the keyboard
controller in your system. When this function is “Enabled”, you can select a typematic
rate and typematic delay.

• Typematic Rate (Chars/Sec)

When the Typematic Rate setting is enabled, you can select a typematic rate (the rate at
which characters repeat) of “6”, “8”, “10”, “12”, “15”, “20”, “24” or “30” characters per
second.

• Typematic Delay (Msec)

When the Typematic Delay setting is “Enabled”, you can select a typematic delay (the
delay before key strokes begin to repeat) of “250”, “500”, “750” or “1000” milliseconds.

• Security Option

If you have set a password, you can select whether the password is required while the
system boots, or only when you enter “Setup”.

• OS Select for DRAM > 64MB

Select “OS2” only if you are running the OS/2 operating system with more than 64 MB
of RAM on your system.

• Video BIOS Shadow

Select “Enabled” to change the video BIOS location form ROM to RAM, where the CPU
can read data through the 64-bit DRAM bus. This can enhance system performance.

• Delay For HDD(Secs)

Default is “’0” .Y ou may need to increase the delay time for BIOS to detect the right type
of HDD for some older HDDs.

finish its precharge. If insufficient time is selected, precharge may be incomplete and
data lost. Options are: “2T” and “3T”.

• Active to Precharge (Tras)

Active to Precharge (Tras) time is the number of clock cycles it takes for DRAM to open
(or make active) a row in a particular bank for the subsequent precharge command. If
insufficient time is selected, the subsequent precharge command might fail. Options
are: “5T” and “6T”.

• Active to CMD (Trcd)

Active to CMD (Command) (Trcd) time is the number of clock cycles it takes for the
DRAM to open a column in a particular row for the subsequent read or write command.
If insufficient time is selected, the subsequent command might fail. Options are: “2T”
and “3T”.

• DRAM Burst Length

The Burst Length determines the maximum number of column locations that can be
accessed for a given Read or Write command. Options are: “4” and “8”.

− Reserved: Legacy ISA Devices, requiring a specific interrupt (such as IRQ4

−−

for serial port1), compliant with the original PC A T bus specification.

• PCI/VGA Palette Snoop

Some VGA cards such as graphics accelerators or MPEG video cards might not show
colors properly . Select “Enabled” to correct this problem. If you don’t have such problems,
leave this field as “Disabled”.

• Assign IRQ For VGA

Select “Enabled” only if your VGA card requires an assigned IRQ. Most ordinary cards
do not, but some high-end cards with video capture function do. Consult your VGA
documentation to set this field. Activity of the selected IRQ always awakens the system.

• Assign IRQ For USB

When “Enabled”, BIOS will assign an IRQ channel for the USB controller .

• PCI Latency Timer (CLK)

Some PCI Devices need more Bus cycle to work normally. You can increase the PCI
Latency Timer setting to solve this problem.

3.9 PC Health Status

This menu provides two thermo-protection functions (CPU warning temperature and shutdown
temperature) and a hardware monitoring center . These features let you know the health status
of your PC.

• CPU Warning Temperature

This field allows you to set the CPU warning temperature. Y ou can choose from “50°C/
122°F” to “70°C/158°F” or even “Disabled” if you like.

• Current CPU Temperature

This field displays the current CPU Temperature.

• Current CPUFAN/SYSF AN1/SYSFAN2 Speed

These fields display the fan speeds of the CPU and system cooling fans.

• VCORE/VDDQ/+3.3V/+5 V/+12 /-12 V/-5V/VBA T(V)/5VSB(V)

These fields display actual system voltage values.

• Shutdown Temperature

This field allows you to set the CPU shutdown temperature. Selections are: “60°C/
140°F”, “65°C/149°F”, “70°C/158°F”, ”75°C/167°F” or “Disabled”.

45 BIOS SETUP

3.10 Frequency/Voltage Control

• CPU Clock Ratio

This function allows you to set the CPU internal frequency ratio. It determines the CPU
internal frequency according to the following formula:

CPU internal frequency = frequency ratio x system bus frequency.*

NOTE: Because AMD has locked the frequency ratio for new CPU settings, this

field to adjust the frequency ratio is usually useless.

••

• Auto Detect DIMM/PCI Clk

••

“Enable” can stop the frequency output for unused DIMM/PCI slots.

••

• Spread Spectrum

••

“Enabled” provides spread Spectrum for better EMI solution.

BIOS SETUP 46

••

• CPU Clock

••

This field allows you to set the CPU Clock Frequency from a minimum of “100” to a
maximum of “132” if the FSB (Front Side Bus) is 100MHz. If the FSB is 133MHz, you can
set this field from “133” to “166”.

••

• FSB Clock

••

This field allows you to change the system FSB (Front Side Bus) Clock. If you want to
select the FSB Clock with this item, remember to set the SW3 to “133”(off, off). (Please
refer to Section 2.4 100/133MHz System Configuration, page 9)

••

• CPU Voltage Requlator

••

You may change your CPU voltage for overclocking; but, this may cause the CPU to
malfunction. Be careful if you want to adjust the CPU voltage.

3.11 Load Fail-Safe Defaults

This option allows you to load the troubleshooting default values permanently stored in the BIOS
ROM.

NOTE: These default settings are non-optimal and disable all high performance

features.

47 BIOS SETUP

3.12 Load Optimized Defaults

This option allows you to load the default values to the system configuration fields. These
default values are the optimized configuration settings for the system.

3.13 Supervisor Password

This option allows you to set a password to prevent others from changing the BIOS settings of
your system.

The password prevents any unauthorized use of your computer. If you set a password, the
system prompts for the correct password before you boot or access “Setup”.

To set a password:

BIOS SETUP 48

1. At the prompt, type your password. Your password can be up to 8 alphanumeric
characters. When you type the characters, they appear as asterisks on the password
screen box. After typing the password, press the [Enter] key.

2. At the next prompt, re-type your password and press the [Enter] key again to confirm the
new password. After password entry, the screen automatically reverts to the main
menu screen.

To disable the password, press the [Enter] key when prompted to enter the password. The
screen displays a message confirming that the password has been disabled.

Forget the password?

If you forget the password, you can clear it by erasing the CMOS Real Time Clock (RTC) RAM
with jumper 1 (JP1). (See “2.5 Clear CMOS Jumper”.) To erase the RTC RAM:

1. Record your BIOS settings. Unplug your computer.

2. Set JP1 to “Clear CMOS” for about 10 seconds, then return to “Normal”.

3. T urn on your computer .

4. Hold down [Delete] key during the POST process and enter BIOS setup to re-configure
the BIOS settings.

3.14 Set User Password

This option allows you to set a password to prevent others from changing the BIOS setting of
your system. This operation is the same as Supervisor Password.
