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.

The following topics are included in this chapter:

• 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.

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.

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 Series :

• This series only supports up to 2GB unbuffered DDR SDRAM, with 2 DDR

DIMM sockets on board. Do not insert other type of modules into these
sockets.

• DDR DIMM socket has 184-pins and one notch. Insert a DDR SDRAM

vertically into the 184-pin socket with the 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 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 LED1 -- DIMM On Power:

An indicator LED1 is designed on board. Whenever system is started
or is in STR status (Suspend to RAM), all DIMMs on board will also get
powered on with the set voltage, resulting in LED1 lighting up. This
indicator is to warn users that, whenever DIMM socket is powered on,
no memory module should be removed from or added to it.

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 1 System Clock Generator Adjust

This Series of mainboards are built with a 5-DIP Switch on board, by
which user can select a CPU clock to match with the Pentium 4 proces­sor selected on board. Yet users are not recommended to take Switch
1 as a tool for overclocking. It is saver and more advisable for users to
select the CPU clock as close as possible to the one marked on the
selected CPU.

Advice from our Engineering Team :

CPU Overclocking should always take all other components on board
into account. No matter what Host clock your CPU has , any attempt to
set your CPU to higher clock than the host will get no guaranty of
success. Instead, you are taking the risk of breaking the stability of
your CPU as well as the mainboard.

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, return the JBAT1 setting
to Pin1-2 closed.

4. CMOS data are restored to default. Remem

ber never clear CMOS when system power is
on.

2-8.3 Jp2 and Jp3 RAM Voltage Select:

• Jp2 and Jp3 are designed on board for user to raise the RAM voltage so
as to get a faster transfer rate. However, the default voltage 2.5V should
be the safest one.

• These fan connectors support CPU/AGP/Chassis 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.
Sensor Fan supports Hardware Monitor chipset on board to implement
the hardware 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.

What RT1 does is to transmit the thermal signal to BIOS or Hardware
Monitor.

2. Connector RT2: A thermal cable is needed to connect RT2 to on­board devices such as HDD, Graphics card etc., so as to detect the
temperature generated therein. Please connect the end (a) of the
thermal cable to mainboard RT2 header, and tape another end (b) of
thermal cable on to the device which you want to monitor. After you
have finished the thermal cable installation, you will see the detected

• 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 freeIRQs 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

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 Run-Time Service.

The following topics are included in this chapter:

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

51

85DR / 85DRB

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.

52

Chapter 4 BIOS Setup

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.

53

85DR / 85DRB

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 Optimized Defaults” or “Load Optimal Defaults”
and save this change.

Boot Up Floppy Seek When 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
270KB, 1.2MB, and 1.44MB capacity all have 80
tracks. Because very few modern PCs have 40-track
floppy drives, we recommend that you set this field
to disabled to save time.

CPU L1 & L2 Cache Cache memory is additional memory that is much

faster than conventional DRAM (system memory).
CPUs from 486-type up contain internal cache
memory (L1), and most, but not all, modern PCs
have additional (external) cache memory (L2).
When the CPU requests data, the system transfers
the requested data from the main DRAM into cache
memory, for faster access by the CPU.

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.

UATA (Ultra AT Attachment), ATA/66, ATA/100, ATA133
ATA is the specification of disk drive interface, that integrates the con­troller on the disk drive itself with the IDE technology.

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

UATA/100/133 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 UATA/100/133, you need spe­cial 80-wire IDE cable, the same as UATA/66.

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

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, re­program, 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
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
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 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.

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

medium speed peripherals (less than 10Mbit/s) such as keyboard,
mouse, joystick, scanner, printer and modem.

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.
