Chapter 2 Hardware Setup

To Get Things Ready for Hardware Setup !

1. We recommend to install your CPU before any other components.
For detailed installation instructions of a processor, you can also
refer to the pamphlet enclosed in your CPU package.

2. Installing a cooling fan with a good heat sink is a must for proper
heat dissipation for your CPU. Get ready an appropriate fan with
heat sink for proper installation. Improper fan and installation will
damage your CPU.

3. In case CPU Vcore, CPU clock or Frequency Ratio is adjustable on
board, please follow the instructions described in the User’s manual
for proper setup. Incorrect setting will cause damage to your CPU.

The following topics are included in this chapter:

2-1 Pentium 4 CPU Installation

2-1.1 To Identify a Pentium 4 CPU

Intel

PENTIUM 4

2.80 GHz / 512 / 800

(Hyper-Threading & Prescott CPU included)

3) System Bus

2) CPU L2 Cache

1) CPU Working Frequency

On the heatsink side of a Pentium 4 CPU, there printed a line of figures
to identify its specifications. The line consists of 4 parts:

1. CPU Working Frequency: this part depicts the working frequency of

the CPU. The Intel P4 processor with three differeent System Bus

mode provides a variety of speeds ranging from 2A Ghz to 3.2Ghz.

400MHz System Bus: 2.60, 2.50, 2.40, 2.20, 2A GHz
533MHz System Bus: 3.06, 2.80, 2.66, 2.53, 2.40, 2.26 GHz
800MHz System Bus: 3.20, 3, 2.80C, 2.60C, 2.40C GHz

2. CPU L2 Cache: this part depicts the L2 Cache size. For example,

512 stands for 512 KB L2 Cache; 256 stands for 256 KB L2 Cache

3. System Bus: this part depicts the System Bus (Front Side Bus) is

provided by CPU clock x 4. For example,
800MHz = 200MHz(CPU clock) x 4; 533MHz = 133MHz x 4
400MHz = 100MHz x 4

Note: System Bus vs CPU Clock
P4 CPU is a quad-pumped CPU. The system bus is provided by the
CPU clock x 4. Therefore, users can figure out the P4 CPU clock by the
System Bus divided by 4.

Pentium 4 with Hyper Threading Technology :
(1) P4 processors at 2.40C, 2.60C, 2.80C, 3, 3.20GHz with an advanced
800MHz system bus
(2) P4 processor at 3.06Ghz with 533MHz system bus

2-1.2 CPU Installation with Socket 478B

This mainboard is built with CPU
Socket 478B ( 478-pin) supporting
the Intel Pentium 4 CPU:

• Follow the steps described in this
section to install the 478-pin Pen­tium 4 CPU into the on board
Socket 478.

• After installation of Pentium 4 CPU,
you must also install the specific
Pentium 4 CPU fan designed in
tandem with this CPU. This CPU
Fan installation is described in next
section.

• This mainboard supports Hyper­threading dual-in-one CPU, the
function of which can be enabled
by Windows XP. (See illustration
on the right.)

1. First pull sideways the lever of
Socket 478, and then turn it up

0

so as to raise the upper layer

90
of the socket from the lower
platform.

( If Hyper-threading CPU is
installed successfully with O/S
Win XP, the O/S will enable the
dual-in-one CPU function.)

Pin 1

2. Configure Pin 1 of CPU to Pin 1
of the Socket, just as the way
shown in the diagram on the
right. Adjust the position of CPU
until you can feel all CPU pins
get into the socket with ease.

3. Make sure that all CPU pins have
completely entered the socket
and then lower down the lever
to lock up CPU to socket.

2-3 Memory Installation

How to tackle the memory Modules:

• Make sure to unplug your power supply before adding or removing
memory module.

• Pay attention to the orientation of the DIMM slots. Forcing a DIMM
into a slot improperly will damage the memory module and slot itself.

• Make sure you have the right type of memory module for your
mainboard.

2-3.1 To Install DDR DRAM Module for this Series :

• This series only supports up to 2GB unbuffered DDR 333/266 DRAM,
with 2 DDR DIMM slots on board. Do not insert other type of mod­ules into these slots.

• DDR DIMM slot has 184-pins and one notch. Insert a DDR DRAM
vertically into the 184-pin slot with the notch-to-rib matching. Press
the Module down in a gradual way until it surely reaches the bottom
and clicks straight up the two latches on the left and right of the slot.
If any one of the latches has not turned up completely, you should
unplug the module and press it down a bit more firmly.

Chapter 2 Hardware Setup

2-4 To Install AGP4X with LED & Jumper Safeguard

1. The AGP slot on board supports 1.5V AGP 4X card only. Any 3.3V

AGP 2X card will burn the 1.5V circuitry. Jp3 is designed on board to
safeguard the AGP slot against the 3.3V AGP 2X card.

2. Default setting of Jp3 1-2 closed is to enable the safeguard, allowing

only 1.5V AGP 4X card to boot system. In this case, if user cannot
boot with an AGP card inserted in AGP slot, it indicates that the AGP
card is not a 1.5V type.

3. Setting Jp3 2-3 closed will disable the safeguard, allowing a PCI

VGA card to boot system.

4. LED1 is a Warning LED. Whenever an AGP card is not inserted to

the AGP slot, or if the card is not a correct one, LED1 will keep lighting
up until a proper installation is done.

How to tackle the Jumpers:

123

A 3-pin Jumper

If a pin-header (of 2 or more pins) is
designed in such a way that its pins
can be closed or linked together to
set up a specific function,
is called a jumper in this manual.

this header

A 2-pin
Jumper
Cap

The conductor inside the cap
links two header-pins together.

• A Jumper is usually but not necessarily given a “JpX” legend.

• In the Jumper setting diagram, the jumper pins covered with
black marks stand for closed pins with jumper cap.

1 13313

Jp X

Jumper with

Pin 2-3 closed

Jumper with

Jumper with

Pin 1-2 closed

• Do not remove any jumper cap when power is on. Always
make sure the power is off before changing any jumper settings.
Otherwise, the mainboard will be damaged.

2-8.1 CPU Clock Select

JFSB1 is designed to select 100/133MHz CPU
clock for the system. Setting JFSB1 to 1-2
closed will allow CPU on board to Auto Detect
its own frequency and apply it to the System
Bus.
Setting JFSB1 to 2-3 closed will manually con­figure a 100MHz CPU to 133MHz.
However, overclocking should always take the
whole mainboard into account. There is no 100%
guaranty of success. In case overclocking fails,
system boot will fail. You should then take the
Auto Detect setting to boot system. Even more,
you should clear CMOS before rebooting
system. ( See JBAT 1 Clear CMOS ).

Chapter 2 Hardware Setup

Further Notes on CPU Overclocking:

1. If you have successfully booted system, with or without CPU
overclock, you still can try another CPU overclock in BIOS Setup.
Please enter BIOS Setup, choose “Frequency/Voltage Control” menu,
and take the “Use Linear” option of the “Use CPU Linear Frequency”.
Then configure the “CPU Clock” item to raise your CPU clock.

2. CPU overclocking should take all components on board into account.
If you fail in BIOS overclocking, you will not be able to restart system.
In such case, Power off system and clear CMOS by JBAT1 and then
restart your system. And remember to reconfigure whatever should
be reconfigured.

3. If your system is already fixed in a cabinet or case, you may not like
to take the trouble to clear CMOS. Then power on your system with
the power button on the PC case and simultaneously press down the
“Insert” key on the keyboard until you see the initial bootup screen
appear. And remember you should also enter CMOS BIOS Setup
instantly and choose “Load Optimized Defaults” to restore default
BIOS .

2-8.2 Clear CMOS

When you have problems with rebooting your system, you can clear
CMOS data and restore it to default value. To clear CMOS with Jumper
JBAT1, please follow the steps below:

1. Power off system.

2. Set JBAT1 to Pin 2-3 closed.

3. After 2 or 3 seconds, restore the JBAT1 setting to Pin1-2 closed.

4. CMOS data are restored to default now. Remember never clear

CMOS when system power is on.

2-8.3 AGP 4X Safeguard

1. The AGP slot on board supports 1.5V
AGP 4X card only. Any 3.3V AGP 2X
card will burn the 1.5V circuitry. Jp3 is
designed on board to safeguard the
AGP slot against the 3.3V AGP 2X
card.

2. Default setting of Jp3 1-2 closed is to
enable the safeguard, allowing 1.5V
AGP 4X card to boot system only. In
this case, if system cannot boot with

AGP4X Safeguard

Jp3:

1

Safeguard Enabled

1-2 closed for 1.5V AGP 4X

1

Safeguard Disabled

2-3 closed for PCI VGA to boot PC;
(Warning: 3.3V AGP card will burn

1.5V circuitry.)

(default)

an AGP card inserted in AGP slot, it
indicates that the AGP card is not one
of 1.5V types.

3. Setting Jp3 2-3 closed will disable the safeguard, allowing a PCI
VGA card to boot system.

Warning: If a 3.3V AGP 2X card is now mistakenly inserted for booting

the system, the high voltage will burn the 1.5V circuitry on board.

Never use a 3.3V or an unknow AGP card on this mainboard.

2-8.4 JKB1: PS/2 KB/Mouse Power On

JKB1 is designed to enable / disable PS/2 Keyboard/Mouse Power on
function. Setting JKB1 to 1-2 closed will disable this function. Setting
JKB1 to 2-3 closed will enable this function. Yet users still have to choose
the K/B Power-on mode on BIOS. (See Integrated Peripherals” in BIOS
Setup.)

JP9 is a 3-pin jumper for enabling or disabling the on-board LAN
Controller. Users can set JP9 1-2 closed to enable the on-board LAN
Controller so as to set up the LAN driver, or to set JP9 2-3 closed to
disable the on-board LAN Controller. In such case, users are free to
use an add-on PCI LAN card for networking.

Both Sensor and No-sensor Fan Connectors support CPU/AGP/Sys­tem/Case cooling fan with +12V mode. When connecting the wire to
any Fan Connector, users should make sure that the red wire is for the
positive current and should be connected to pin +12V, and the black
wire is Ground and should be connected to pin GND.

A Hardware Monitor chipset is on board, with which users can install
a Hardware Monitor Utility and read the fan speed transmitted from the
sensor fan. Otherwise, users can read the fan speed from the “Hard­ware Monitor Status” in CMOS BIOS.

A running Fan will send out 2 electric pulses per rotation of its fan
blade. A Sensor Fan Connector will count the electric pulses and send
the information to the System Hardware Monitor which in turn will work
out the fan rotation speed and display it on screen.

Chapter 4 AMI BIOS Setup

THE BIOS

BIOS stands for Basic Input and Output System. It was once called
ROM BIOS when it was stored in a Read-Only Memory (ROM) chip
Now manufacturers would like to store BIOS in EEPROM which means
Electrically Erasable Programmable Memory. BIOS used in this series
of mainboard is stored in EEPROM, and is the first program to run when
you turn on your computer.

BIOS performs the following functions:

1. Initializing and testing hardware in your computer (a process called
“POST”, for Power On Self Test).

2. Loading and running your operating system.

3. Helping your operating system and application programs manage
your PC hardware by means of a set of routines called BIOS Run­Time Service.

This Chapter includes the following topics :
4-1 About BIOS Setup
4-2 To Run BIOS Setup
4-3 About CMOS
4-4 The POST (Power On Self Test)
4-5 To Update BIOS
4-6 BIOS Setup

54

Chapter 4 BIOS Setup

4-1 About BIOS Setup

BIOS setup is an interactive BIOS program that you need to run when:

1. Changing the hardware of your system. (For example: installing a
new Hard Disk etc.)

2. Modifying the behavior of your computer. (For example: changing
the system time or date, or turning special features on or off etc.)

3. Enhancing your computer’s behavior. (For example: speeding up
performance by turning on shadowing or cache)

4-2 To Run BIOS Setup

First access BIOS setup menu by pressing < DEL > key after “POST” is
complete ( before OS is loaded ). BIOS will then display the following
message:

DEL:SETUP

4-3 About CMOS

CMOS is the memory maintained by a battery. CMOS is used to store
the BIOS settings you have selected in BIOS Setup. CMOS also
maintains the internal clock. Every time you turn on your computer, the
BIOS Looks into CMOS for the settings you have selected and configures
your computer accordingly. If the battery runs out of power, the CMOS
data will be lost and POST will issue a “CMOS invalid” or “CMOS
checksum invalid” message. If this happens, you have to replace the
battery and check and configure the BIOS Setup for the new start.

4-4 The POST ( Power On Self Test )

POST is an acronym for Power On Self Test. This program will test all
things the BIOS does before the operating system is started. Each of
POST routines is assigned a POST code, a unique number which is
sent to I/O port 080h before the routine is executed.

55

85DR3-C / 85DR3-CL

4-5 To Update BIOS

• System BIOS is incorporated into a Flash memory component. Flash

BIOS allows user to upgrade BIOS without the need to replace an EPROM
component.

• The Upgrade Utility can be loaded on a floppy diskette for upgrading

saving, and verifying the system BIOS. The Update Utility can also be
run from a hard disk drive or a network drive.

• It is highly recommended that you save a copy of the original mainboard

BIOS along with a Flash EPROM Programming utility (AMIXXX.EXE)to a
bootable floppy disk so that you can reinstall the BIOS when in need.

• Normally, to update BIOS is unnecessary if the system is working fine.

Users should only update BIOS when incompatible problems are encoun­tered or new features have to be added to system.

• “AMIFLASH.EXE” is a Flash EPROM Programming utility that updates

the BIOS by uploading a new BIOS file to the programmable flash ROM
on the mainboard. This program only works in DOS environment, the

utility can not be executed in Win95/98, ME, NT, WINDOWS 2000 or
Windows XP environment.

• Please follow the steps below for updating the sys­ tem BIOS:

Step 1. Please visit the board maker’s website, download the zip files
of the latest BIOS and AMI flash utility “AMIFLASH.EXE” for your
mainboard. After unzipping, the BIOS file format will be *.ROM, of which
“ * ” stands for the specific BIOS file name.

Step 2. Create a bootable diskette. Then copy the BIOS file and AMI
flash utility “AMIXXX.EXE” into the diskette.

Step 3. Insert the diskette into drive A, boot your system from the
diskette.

56

Chapter 4 BIOS Setup

Step 4. Under “ A “ prompt, type “ AMIXXX.EXE *.ROM “ and then
press <Enter> to run BIOS update program. Please note that there
should be a space between AMIXXX.EXE and *.ROM. (*.ROM depends
on your mainboard model and version code. Instead of typing “*”, you
should type the specific file name for your specific mainboard). For
example, you may type “amiflash(space)DR3C005.rom”.

Step 5. When the message “Flash ROM Update Completed - Pass.”
appears, please restart your system.

Step 6. You will see a message “CMOS Memory Size Wrong” during
booting the system. Press <Del> or <F1> to run CMOS setup utility,
then reload “LOAD SETUP DEFAULTS” or “Load Optimal Defaults”
and save this change.
