Intel

pentium 4

2.4 GHz / 512 / 533 / 1.5V

4) CPU Voltage Vcore

3) System Clock

2) CPU L2 Cache

1) CPU Working Frequency

On the heatsink side of a Pentium 4 CPU, there printed is 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. For example:

2.4 GHz depicts that this CPU is locked to 2.4 GHz working frequency

(multiplier 18 x 133MHz CPU clock);

2A GHz depicts that this CPU is an A version, locked to 2.0 GHz

working frequency (multiplier 20 x 100MHz CPU clock);

2) CPU L2 Cache: This part depicts the L2 Cache size. For Example:
512 stands for 512 MB L2 Cache; 256 stands for 256 MB L2 Cache;

3) System Clock: This part depicts the System Clock (Front Side Bus)

to be provided by the CPU. For example:

533 stands for a 533MHz system bus which will be provided by this

133MHz CPU times 4;
400 stands for a 400 system clock provided by a 100 MHz CPU x 4;
(Note: P4 CPU is a quadpumped CPU. The system bus is provided by
the CPU clock x 4. Therefore, user can figure out the P4 CPU clock by
the System Clock devided by 4.)

2-3 Memory Installation

How to tackle with the memory Modules:

• Make sure to unplug your power supply before adding or removing
memory module. Failure to do so may cause severe damage to both
your mainboard and the 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 SDRAM Module for this Series :

• This series only supports up to 2GB unbuffered DDR 266/200 SDRAM,
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 SDRAM
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.

2-3.3 Indicator LED1: DIMM Powered On:

An indicator LED 1 is designed on board. Whenever system is started,
all the DIMM slots on board will also get powered on, resulting in LED 1
lighting up. This indicator is to warn users that, whenever DIMM slot
is powered, no memory module should be removed from or added into
it.

2-4 Install VGA / AGP4X with LED2 & Jp11 Safeguard

1. To install on-board VGA, please connect your monitor directly to VGA

connector on board. Default Jp11 (2-3 closed) is designed to assure
booting system with 1.5V on-board VGA or 1.5V AGP4X add-on card.
User can choose either VGA or AGP4X as the initial display by
changing BIOS Setup (see “PNP/PCI Configurations” in BIOS Setup).

However, if 3.3V AGP 2X card is 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. A safe installation of AGP4X add-on card is set Jp11 to 1-2 closed,

resulting in allowing only 1.5V AGP 4X card to boot system. With
Jp11 1-2 closed, system even cannot boot with on-board VGA. 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 AGP card. The AGP card
should be changed until a 1.5V AGP4X card is inserted.

3. LED2 is a Warning LED. Whenever Jp11 is set at 1-2 closed for an

AGP4X card installation, and if the AGP slot is yet left empty, or if
the AGP card is not a correct one, LED1 will light up until a proper
installation is done.

VGA/AGP4X Safeguard

1

1-2 closed for 1.5V AGP 4X
only; (Warning: 3.3V AGP 2X
card will not boot system.)

2-3 closed for VGA or 1.5V AGP 4X
only;(Warning: 3.3V AGP card will
cause 1.5V circuit burn.)

To set up Power Supply on this mainboard:

1. Connect the on-board Main Power Connector (20-pin) to the Main
Power Connector (20-pin) of an ATX Power Supply which can be
either of the latest version 2.03 or of earlier ATX format.

2. If you use an ATX Power Supply Version 2.03 or later, you can now
connect the on-board square-shaped +12V Connector to the square­shaped +12V Connector of your ATX Power Supply. In this case, it is
not necessary for you to connect the on-board 4-pin Peripheral Power
Connector to your Power Supply.

3. If you use an ATX power Supply of an older version than V2.03, you
cannot find a square-shaped +12V Connector with your Power Supply;
you must then connect the on-board 4-pin Peripheral Power
Connector to the 4-pin Peripheral Power Connector of your Power
Supply.

Chapter 2 Hardware Setup

How to tackle with Jumpers:

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

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

2-8.1 Jp 4: CPU Clock Select

Jp 4 is designed to select 100/133MHz CPU
clock for the system. Setting Jp 4 to 1-2 closed
will allow CPU on board to autodetect its own
frequency and apply it to the System Bus.
Setting Jp 4 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
Autodetect setting to boot system. Even more,
you should clear CMOS before booting system
( See JBat 1 Clear CMOS ).

Note on CPU Overclocking:

1. If you have successfully booted system with or without CPU overclock,
you still can do 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 as stated
in next section and then restart your system. And remember
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 cabinet and simultaneously press down the
“Insert” key of the keyboard until you see the initial bootup screen
appear. And remember you should also enter CMOS BIOS Setup
and choose “Load Optimized Defaults” to restore default BIOS .

27

85MR2 / 85MR2-L

2-8.2 JBat 1: Clear CMOS

When you have problem 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 JBat 1 to Pin 2-3 closed.

3. After 2 or 3 seconds, restore the JBat 1 setting to Pin1-2 closed.

4. CMOS data are restored to default now. Remember never clear
CMOS when system power is on.

Jp1 is designed to select keyboard or the Power button as the power­on controller. Setting Jp3 to 1-2 closed will allow user to power on sys­tem by power button. Setting Jp3 to 2-3 closed will allow user to power
up system by keyboard. Yet user still has to enter BIOS Setup for choos­ing the K/B Power-on mode. (See Integrated Peripherals” in BIOS
Setup.)

Jp10 is a 2-pin jumper for enabling or disabling the on-board LAN
Controller. Setting Jp10 OPEN will allow user to enable on-board LAN
Controller so as to allow user to set up the LAN driver.
Setting Jp10 CLOSED will allow user to disable the on-board LAN
Controller. In such case, user is free to use an add-on PCI LAN card
for the networking.

choose either VGA or AGP4X as
the initial display by changing BIOS
Setup (see “PNP/PCI
Configurations ” in BIOS Setup).
However, if 3.3V AGP 2X card is mistakenly inserted for booting the

2-3 closed for VGA or 1.5V AGP 4X
only;(Warning: 3.3V AGP card will
cause 1.5V circuit burn.)

system, the high voltage will burn the 1.5V circuitry on board. Never
use a 3.3V or an unknow AGP card in this case.

2. Boot system with AGP4X add-on card only:
To assure the use of a correct AGP4X card of 1.5V, please set Jp11

to 1-2 closed, resulting in that it will allow only 1.5V AGP 4X card to
boot system. With Jp11 1-2 closed, system cannot boot with on-board
VGA or AGP2X card. In this case, if user cannot boot with an AGP
card inserted in AGP slot, it indicates that the AGP card is a wrong
one. The AGP card should be changed until a 1.5V AGP4X card is
inserted.

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, user 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 user can install a
Hardware Monitor Utility and read the fan speed transmitted from the
sensor fan. Otherwise, user 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 with the monitoring program.

• Both ISA and PCI expansion cards may require IRQs. System IRQs are
available to cards installed in the ISA expansion bus first, then any remain­ing IRQs are available to PCI cards. Currently, there are two types of ISA
cards.

• The original ISA expansion card design, now referred to as “Legacy” ISA
card, requires you to configure the card’s jumpers manually and then install
it in any available slot on the ISA bus. To see a map of your used and free
IRQs in Windows 98, the Control Panel in My Computer, contains a Sys-
tem icon, which gives you a Device Manager tab. Double-Clicking on a
specific hardware device gives you a Resources tab which shows the In­terrupt number and address. Double-Clicking Computers to see all the in­terrupts and addresses for your system. Make sure that each ISA device
should be assigned to one IRQ respectively. If ISA device share IRQ with
any other device, your computer will easily get into trouble.

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:

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.

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 latest BIOS
file and AMI update utility. The file name of AMI update utility will be
“AMIXXX.EXE” of which “ XXX ” stands for the version number of the
file. 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.

60

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).

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.
