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 processor, you can also refer
to the pamphlet enclosed in your CPU package.

2. Installing a cooling fan with a good heatsink is a must for proper heat

dissipation for your CPU. Get ready an appropriate fan with heatsink
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 manual
for proper setup. Incorrect setting will cause damage to your CPU.

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 main
board and the memory module.

• Pay attention to the orientation of the DIMM slots. Forcing a DIMM in a

socket improperly will damage the memory module and socket.

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

2-3.1 To Install DDR SDRAM Module for this Mainboard :

1. This mainboard only supports unbuffered DDR SDRAM. Do not insert
other type of DDR SDRAM therein.

2. For DDR333, this mainboard can support up to 2GB memory in two
DIMMs.That is, you can only use 1 or 2 DDR333 SDRAM modules.

3. For DDR266/200, this mainboard can support up to 3 GB memory in
3 DIMMs.

4. DDR DIMM socket has 184 pins and one notch. Insert a DDR SDRAM
vertically into the 184-pin socket with its notch matching the one in
the socket. 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 side of the socket. If any one of the latches has not turned
up completely, you should unplug the module and press it down the
socket a bit more firmly.

Chapter 2 Hardware Setup

2-3.2 To Remove a DIMM:

Press down the holding latches on both sides of socket and the module
will be released from the DIMM socket.

2-3.3 Indicator D7 for DIMM Socket Power On:

An indicator D7 is designed on board. Whenever system is started or
is in STR status (Suspend to RAM), all the DIMM sockets on board will
also get powered on with the set voltage, resulting in D7 lighting up.
This indicator D7 is to warn users that, whenever DIMM socket is
powered, no memory module should be removed from or added into it.

Intel Pentium 4 requires power support of ATX V2.03. To set up ATX2.
03 Power Supply on this mainboard, Please take the following steps:

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 a version earlier 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 Switch S3 for CPU Clock Select

1. This mainboard is shipped to users with a 5-DIP Switch on board, by
which user can select a CPU clock to match with the Pentium 4
processor installed on board. Yet users are not recommended to
take Switch S3 as a foolproof tool for overclocking. Instead, it is
saver and more advisable to select the CPU clock as near as possible
to the one marked on the selected CPU.

2. An Advice from our Engineering Team:

CPU Overclocking should always take the on-board components into

account. If you are using DDR266 SDRAM on this mainboard, you must
not set the switch S3 to the DDR333 settings; otherwise you risk system
damage.

When you have problem with rebooting you system, you can clear
CMOS data and restore it to default value. To clear CMOS with Jumper
Jp10, please follow the steps below:

1. Power off system;

2. Set JBAT1 to Pin 2-3 closed.

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

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

2-8.3 Jp2 & Jp3 DIMM Voltage Select:

The default voltage 2.5V at DIMM sockets is for normal operation of
the supported DDR SDRAM. In some case, when you try to do CPU
overclocking, you then may also need to raise the transfer rate of the
memory interface. Jp2 & Jp3 are designed on board to provide set­tings for selecting a higher DIMM voltage so as to raise the speed of
the memory interface.

Warning: In selecting a higher voltage than the default
one, you are risking the stability of your system.

These fan connectors support CPU/Power/AGP/System cooling fan
with +12V. When connecting the wire to FAN connectors, 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. If your mainboard has Hardware Monitor chipset
on board, you must use a specially designed fan with speed sensor to
take advantage of the monitoring function.

For fans with speed sensors, each rotation of the fan blades will send
out 2 electric pulses, by which System Hardware Monitor will work out
the fan rotation speed by counting the pulses.

NOTE : 2 “Yellow” fan connectors are used on this series to mark that

they support fan speed sensor function. The other two white fan connectors
do not support sensor function.

• 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
System 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 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 upgrade BIOS
4-6 BIOS Setup

44

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 do some proper settings in BIOS Setup.

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.

45

85DRS2

4-5 To upgrade 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 to execute saving,

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

4-5.1 Before Upgrading BIOS

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

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

4-5.2 Upgrade Process

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

Users should only upgrade the BIOS when you experience incompatible
problems or need to create new features.

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

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 upgrading the system BIOS:

Step 1. Please visit the board maker’s website, download latest BIOS
file and AMI flash utility “AMIFLASH.EXE”. 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 “AMIFLASH.EXE” into the diskette.

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

46

Chapter 4 BIOS Setup

Step 4. Type AMIFLASH *.ROM and then press <Enter> to run BIOS
upgrade program. (*.ROM depends on your mainboard model and
version code. Instead of typing “*”, you should type 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.

Appendix-2 Technical Terms

AC’97
AC’97 is a device designed to include a digital processor for modem and
an audio CODEC for analog I/O. These two parts are linked together by
AC’97 link bus. Putting the digital processor into the main system chipset
will reduce the cost of sound/modem onboard solution.

ACPI (Advanced Configuration & Power Interface)
ACPI is developed together by Intel, Microsoft and Toshiba. This
interface provides a channel of management of the PC system and its
hardware such as CPU and BIOS, pushing the PC power management to a
more advanced and user-friendly level.

AGP (Accelerated Graphic Port)
AGP is a bus interface targeted for high-performance 3D graphics. AGP
takes advantage of both rising and falling edge of the 66MHz clock. For
2X AGP, the data transfer rate is 66MHz x 4byte x 2 = 528MB/s. AGP
4X mode is 66MHz x 4byte x 4 = 1056MB/s.

AMR (Audio/Modem Riser)
AMR is an interface to connect the CODEC circuit of AC’97 sound/
modem solution to the mainboard through an AMR card and an AMR
connector.

APM (Advanced Power Management)
APM is developed by Intel and Microsoft , intending for PC power
management through the system BIOS. Through APM, the PC power
consumption can be reduced to 5W or lower.

ATA (AT Attachment), ATA/66, ATA/100
ATA is the specification of disk drive interface, that integrates the
controller on the disk drive itself with the IDE technology.

ATA/66 uses both rising edge and falling edge to provide a data transfer
rate 16.6MB/s x4 = 66MB/s. To use ATA/66, you need special ATA/66
IDE cable.

ATA/100 also uses both rising edge and falling edge as ATA/66, but clock
cycle time is reduced to 40ns. The data transfer rate is (1/40ns) x 2 bytes x
2 = 100MB/s. To use ATA/100, you need special 80-wire IDE cable, the
same as ATA/66.

76

Appendices

ATAPI (AT Attachment Packet Interface)
This is the exension of the EIDE (extended IDE) that enables the interface
to support CD-ROM players and tape drives.

BIOS (Basic Input/Output System)
BIOS is a set of assembly routine/program that resides in EPROM or
Flash ROM. BIOS controls Input/output devices and other hardware
devices of the mainboard. Generally, operation system and drivers will
access BIOS before accessing hardware devices so as to enhance the
portability of the hardware devices.

Bus Master IDE (DMA mode)
An IDE interface is an interface for mass storage devices, in which the
controller is integrated into the disk or CD-ROM itself. To reduce the
workload of the CPU, the bus master IDE device transfers data from/to
memory without interrupting CPU, and releases CPU to operate
concurrently while data is transferring between memory and IDE device.
You need the bus master IDE driver and the bus master IDE HDD to
support bus master IDE mode.

CAS (Column Address Strobe)
CAS is a technology of DRAM writes and reads. The number of clock
cycles of the CAS signals is depending on the DRAM timing.

CMOS Chip (Complementary Metal Oxide Semiconductor Chip)
CMOS Chip is built on CMOS Technology, by which CMOS Chip can
store data with very slow power supply.

CNR (Communication and Networking Riser)
CNR interface provides a cost reducing method of implementing LAN,
home networking, DSL, USB, wireless, audio and modem subsystems
through a CNR card and a CNR connector.

CODEC (Coder and Decoder)
Normally, CODEC means a circuit that can do digital to analog
conversion and vice versa. It is part of AC’97 sound/modem solution.

DDR (Double Data Rated) SDRAM
DDR SDRAM essentially doubles the memory speed of SDRAMs
without increasing the clock frequency.

77

Appendices

DIMM (Dual In Line Memory Module)
DIMM socket is built with a 168-pin assignment and supports 64-bit data.
DIMM can be single or double sided. The golden finger signals on each
side of the module are different, and that is why it is called Dual In Line.
Almost all DIMMs are made with SDRAM now, which operate at 3.3V.
Some old DIMMs are made by FPM/EDO and only operate at 5V.

DMA (Direct Memory Access)
Channel for communications between memory and surrounding devices.

ECC (Error Checking and Correction)
The ECC algorithm has the ability to detect double-bit error and
automatically correct single-bit error while parity mode can only detect
single-bit error.

ECP (Enhanced Communication Port)
ECP is a technology designed to improved I/O for parallel ports.

EPP (Enhanced Parallel Port)
EPP is a standard that supports data transfer rates of up to 500 kps for
parallel printers

EDO (Extended Data Output) Memory
Unlike traditional FPM (Fast Page Mode) memory that tri-states the
memory output data to start the pre-charge activity, EDO DRAM holds
the memory data valid until the next memory access cycle, which is
similar to pipeline effect in reducing one clock state.

EEPROM (Electronic Erasable Programmable ROM)
Both EEPROM and Flash ROM can be re-programmed by electronic
signals, but the interface technology is different. Size of EEPROM is
much smaller than flash ROM. BIOS is now generally stored in
EEPROM or Flash ROM.

EPROM (Erasable Programmable ROM)
Traditional mainboard stores BIOS codes in EPROM which can only be
erased by ultra-violet (UV) light. If BIOS has to be updated, you need to
remove EPROM from mainboard, clear data by UV light, re-program, and
then insert it back to socket.

FC-PGA (Flip Chip-Pin Grid Array)
FC means Flip Chip, while FC-PGA is a new package of Intel for
Pentium III CPU. It is compatible with SKT370 socket, but requires

78

Appendices

mainboard to add some signals on socket 370.

Flash ROM
Flash ROM can be re-programmed by electronic signals. It is easier for
BIOS to upgrade by a flash utility, but it is also easier to be infected by
virus. Because of increase of new functions, BIOS size is increased from
64KB to 256KB (2M bit) or more.
FSB (Front Side Bus)
FSB is the data channel connecting the Processor to chipset, RAM,
mainboard buses, AGP socket etc. Its speed is in terms of MHz and is
talked to as FSB clock:
FSB Clock means CPU external bus clock.
CPU internal clock = CPU FSB Clock x CPU Clock Ratio

IEEE 1394
IEEE 1394 is a low-cost digital transfer interface with transfer rate at 100,
200 or 400 Mbps. It provides solutions of connecting digital television
devices and Serial Bus Management. There are two type of IEEE 1394
data transfer: asynchronous and isochronous. Isochronous data channels
provide guaranteed data transport at a pre-determined rate. This is
especially important for time-critical multimedia data where just-in-time
delivery eliminates the need for costly buffering.

Parity Bit
The parity bit mode of error detection uses 1 parity bit for each byte.
Normally it is even parity mode, that is, each time the memory data is
updated, parity bit will be adjusted to have even count “1” for each byte.
Next time when memory is read with odd number of “1”, the parity error
is occurred and this is called single bit error detection.

PC-100 DIMM
SDRAM DIMM that supports 100MHz CPU FSB bus clock.

PC-133 DIMM
SDRAM DIMM that supports 133MHz CPU FSB bus clock.

PC-1600 or PC-2100 DDR SDRAM
PC-1600 DDR SDRAM with a 64-bit data bus doubles the data transfer
rate of PC100 SDRAM and hence provides data transfer bandwidth up to
100x64/8x2=1600MB/s. PC2100 DDR SDRAM doubles the data transfer
rate of PC-133 and hence provides data transfer bandwidth up to 133x64/
8x2=2100MB/s.

PCI (Peripheral Component Interface) Bus

79

Appendices

A high speed data channel for the internal connection of peripheral
devices and the computer system through a PCI expansion card.

PnP (Plug and Play)
The PnP specification suggests a standard register interface for both BIOS
and operating system (such as Windows 95). These registers are used by
BIOS and operating system to configure system resource and prevent any
conflicts. PnP BIOS or operating system will automatically allocate the
IRQ/DMA/Memory. Currently, almost all the PCI cards and most ISA
cards are already PnP compliant.

POST (Power-On Self Test)
The BIOS self-test procedure after power-on. It is generally the first or
the second program shown on your monitor screen during system boot.

RAID (Redundant Array of Independent Disks)
A group of hard disks set up in PC system for data fault tolerance and
better performance. RAID is usually more used in servers than in personal
computers. Different level of RAID stands for different function and
performance:
Level 0 provides data striping or spreading out blocks of files across
multiple disks, and so improvement of performance but no fault
tolerance.
Level 1 provides disk mirroring, and so data backup.
Level 3 provides a dedicated disk for error correction of data, and so
better performance and some fault tolerance.

RAS (Row Address Strobe)
RAS is a technology that DRAM writes and reads to the Row addresses,
while a CAS (Column Address Strobe) signal is used to validate the
column address. The signals are generally sent CAS before RAS.
(in Network field, RAS stands for Remote Access Services).

RDRAM (Rambus DRAM)
Rambus DRAM is a memory technology that uses large burst mode data
transfer of up to 1.6GHz. It is import to know that RDRAM technology
helps set up a system level improvement, not just a component upgrade.

RIMM (Rambus Inline Memory Module)
RIMM is built with a 184-pin architecture module that supports RDRAM
memory technology. A RIMM memory module may contain up to
maximum of 16 RDRAM devices.

80

Appendices

SDRAM (Synchronous DRAM)
SDRAM is one of the Dynamic Random Access Memory (DRAM)
technologies that allow DRAM to use the same clock as the CPU host
clock (EDO and FPM are asynchronous and do not have clock signal).
SDRAM comes in 64-bit 168-pin DIMM and operates at 3.3V.

SIMM (Single In Line Memory Module)
SIMM socket is only 72-pin, and is only single side. The golden finger
signals on each side of PCB are identical. That is why it is called Single
In Line. SIMM is made of FPM or EDO DRAM and supports 32-bit data.
SIMM is phased out in current mainboard design.

SPD (Serial Presence Detect)
SPD is a small ROM or EEPROM device resided on the DIMM or
RIMM. Memory module information such as DRAM timing and chip
parameters can be stored into SPD so that BIOS can access it and use it to
decide best timing for this DIMM or RIMM.

UART (Universal Asynchronous Receiver/transmitter)
UART is built in a chip that controls the data sent to and received from a
serial port. A 16550 UART is now standard in most PCs, and supports
modem speed up to 57,600 bps and beyond and direct connect speed of
115,200 bps. Many UARTs have built-in errors in the internal code and
just do not work correctly with many external modems. UART is also
found as the serial interface on internal modem.

Ultra DMA
Ultra DMA (or, more accurately, Ultra DMA/33) is a protocol for
transferring data at 33.3MB/s between a hard disk drive through the
computer’s data path (or bus) to the computer’s random access memory
(RAM). The transfer data is twice as fast as the previous Direct Access
Memory (DMA) interface. The latest Ultra DMA has advanced to Ultra
DMA/66 and Ultra DMA/100.

16.6MB/s x2 = 33MB/s

16.6MB/s x4 = 66MB/s

16.6MB/s x6 = 100MB/s

USB (Universal Serial Bus)
USB is a 4-pin serial peripheral bus that is capable of cascading low/
medium speed peripherals (less than 10Mbit/s) such as keyboard, mouse,
joystick, scanner, printer and modem.

81

Appendices

VCM (Virtual Channel Memory)
NEC’s Virtual Channel Memory (VCM) is a new DRAM core
architecture that dramatically improves the memory system’s ability to
service multimedia requirements. VCM increases memory bus efficiency
and performance of any DRAM technology by providing a set of fast
static registers between the memory core and I/O pins. Using VCM
technology results in reduced data access latency and reduced power
consumption.

VRM (Voltage regulator Module)
This is a small module installed on a mainboard to regulate the voltage
fed to the processor on board. Voltage regulator can be built on board in
various way. VRM is a socketed type of regulator module which is easier
to change when needed.

Zero Wait State
When memory is operating at its fastest speed in its course of fetching
and yielding data, it allows no “no-op” cycle and is called in a zero wait
state. On the other hand, a memory is in a wait state , after it gets a
command to fetch data, it waits for one , two or more cycles to assure that
the expected data is in the buffer.

ZIP file
Zip file is a compressed file with a reduced file size.

Zoom
To zoom is to make a window or screen larger or smaller in a Graphical
User Interface of a computer system. Usually, to “zoom in” means to
enlarge, and to “zoom out” means to reduce size.
