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.

CHAPTER 1 INTRODUCTION
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
Page 13

(
)
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:

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 .
Page 31
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.
Page 32

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”.
