Intel Pentium 4 Processor Family
Cooling Solutions
As processor technology pushes to faster speeds and higher performance, thermal management
becomes increasingly crucial when building computer systems. Maintaining the proper thermal
environment is key to reliable, long-term system operation. The overall goal in providing the proper
thermal environment is keeping the processor below its specified maximum case temperature.
Heatsinks induce improved processor heat dissipation through increased surface area and
concentrated airflow from attached fans. In addition, interface materials allow effective transfers of
heat from the processor to the heatsink. For optimum heat transfer, Intel recommends the use of
thermal grease and mounting clips to attach the heatsink to the processor.
When selecting a thermal solution for your system, please refer to the website below for collection of
heatsinks evaluated and recommended by Intel for use with Intel processors. Note, those heatsinks are
recommended for maintaining the specified Maximum T case requirement. In addition, this collection
is not intended to be a comprehensive listing of all heatsinks that support Intel processors.

Introduction
The special designed 2-user motherboard allows (P400MTWIN) two users to share the
computing power of a single PC system. With integrated connectivity hardware onboard, the
motherboard comes with innovative software, the MagicTwin®, allowing 2 users to be
connected to it and runs up to two stations directly from it simultaneously. The unique and
copyright-protected MagicTwin® technology makes each of the 2 users feel like having
himself his own Windows-XP computer. Each user needs to have himself his own keyboard,
mouse, sound device, and monitor. All remaining PC hardware are shared, even the IP.
Both users can operate on their own station concurrently just like the operation of a standard
PC. There is no obvious delay because of the Time-slicing/Multiplexing technology built-in.
Each user gets an exact and extremely short defined moment to access to the PC system,
devices, applications and Windows itself. Resources are only claimed for nanoseconds at a
time, usually from electronic memory, or cache. Both users get from Windows and the PC,
what they really need when they need it! The MagicTwin solution turns the single PC into a
cost-effective multi-user system.
The setup is intuitive and easy. In only a few minutes, users can install and start using their
new workstation. No network administrator is needed as everything to network the
workstations together is done automatically with the MagicTwin software. You can add
immediately additional user station to the single system and turn one PC into two.

Processor slot/socket - the slot or socket used to mount the system processor on the motherboard.
Slot (AGP, PCI, ISA, RAM) - the slots used to mount adapter cards and system RAM.
AGP - Accelerated Graphics Port - a high speed interface for video cards; runs at 1X (66MHz),
2X (133MHz), or 4X (266MHz).
PCI - Peripheral Component Interconnect - a high speed interface for video cards, sound cards,
network interface cards, and modems; runs at 33MHz.
ISA - Industry Standard Architecture - a relatively low speed interface primarily used for sound
cards and modems; runs at approx. 8MHz.
Serial Port - a low speed interface typically used for mouse and external modems.
Parallel Port - a low speed interface typically used for printers.
PS/2 - a low speed interface used for mouse and keyboards.
USB - Universal Serial Bus - a medium speed interface typically used for mouse, keyboards,
9
scanners, and some digital cameras.

the relationship between the various components.
Driver - software, which defines the characteristics of a device for use by another device or other
software.
Processor - the "central processing unit" (CPU); the principal integrated circuit used for doing
the "computing" in "personal computer"

the flash memory inside the CPU, normal it depend on CPU type.
2-3-2 About Intel Pentium 4 478-pin CPU
This motherboard provides a 478-pin surface mount, Zero Insertion Force (ZIF) socket,
referred to as the mPGA478B socket supports Intel Pentium 4 processor in the 478 Pin
package utilizes Flip-Chip Pin Grid Array (FC-PGA2) package technology.
The CPU that comes with the motherboard should have a cooling FAN attached to prevent
overheating. If this is not the case, then purchase a correct cooling FAN before you turn on
your system.
WARNING!
Be sure that there is sufficient air circulation across the processor’s
heatsink and CPU cooling FAN is working correctly, otherwise it may
cause the processor and motherboard overheat and damage, you may install
an auxiliary cooling FAN, if necessary.
To install a CPU, first turn off your system and remove its cover. Locate the ZIF socket and
open it by first pulling the level sideways away from the socket then upward to a 90-degree
angle. Insert the CPU with the correct orientation as shown below. The notched corner
should point toward the end of the level. Because the CPU has a corner pin for two of the
four corners, the CPU will only fit in the orientation as shown.
CPU ZIF mPGAB Socket
Colden Arrow
mPGA478B
When you put the CPU into the ZIF socket. No force require to insert of the CPU, then press
the level to Locate position slightly without any extra force.
2-4 Install Memory
10
This motherboard provides two 184-pin DDR DUAL INLINE MEMORY MODULES
(DIMM) sites for DDR memory expansion available from minimum memory size of 64MB to
maximum memory size of 2.0GB DDR SDRAM.

Generally, installing DDR SDRAM modules to your motherboard is very easy, you can refer

DDR2 (BANK2+BANK3)
DDR1 (BANK0+BANK1)
NOTE!
When you install DIMM module fully into the DIMM socket the eject tab
should be locked into the DIMM module very firmly and fit into its
indention on both sides.
WARNING!
For the SDR SDRAM CLOCK is set at 133MHz, use only DDR266- compliant
DDR Modules. When this motherboard operate at 133MHz, most system will
not even boot if non-compliant modules are used because of the strict
timing issues, if your DDR Modules are not DDR266-compliant, set the
SDRAM clock to 100MHz to ensure system stability.

2-5 Expansion Cards
WARNING!
Turn off your power when adding or removing expansion cards or other
system components. Failure to do so may cause severe damage to both
your motherboard and expansion cards.
2-5-1 Procedure For Expansion Card Installation
1. Read the documentation for your expansion card and make any necessary hardware or
software setting for your expansion card such as jumpers.
2. Remove your computer’s cover and the bracket plate on the slot you intend to use.
3. Align the card’s connectors and press firmly.
4. Secure the card on the slot with the screen you remove above.
5. Replace the computer system’s cover.
6. Set up the BIOS if necessary.
7. Install the necessary software driver for your expansion card.
2-5-2 Assigning IRQs For Expansion Card
Some expansion cards need an IRQ to operate. Generally, an IRQ must exclusively assign to
one use. In a standard design, there are 16 IRQs available but most of them are already in use.
Standard Interrupt Assignments

If using PCI cards on shared slots, make sure that the drivers support
“Shared IRQ” or that the cards don’t need IRQ assignments. Conflicts will
arise between the two PCI groups that will make the system unstable or
cards inoperable.

ATX Power Supply connector. This is a new defined 20-pins connector that usually
comes with ATX case. The ATX Power Supply allows to use soft power on momentary
switch that connect from the front panel switch to 2-pins Power On jumper pole on the
motherboard. When the power switch on the back of the ATX power supply turned on,
the full power will not come into the system board until the front panel switch is
momentarily pressed. Press this switch again will turn off the power to the system
board.
