Intel®Pentium®4 processors
The Intel Pentium 4 processor, Intel's most advanced, most powerful processor for
desktop PCs and entry-level workstations, is based on Intel NetBurstTM
microarchitecture. The Pentium 4 processor is designed to deliver performance
across applications and usages where end-users can truly appreciate and experience
the performance. These applications include Internet audio and streaming video,
image processing, video content creation, speech, 3D, CAD, games, multimedia, and
multi-tasking user environments. The Pentium 4 processor delivers this world-class
performance for consumer enthusiasts and business professional desktop PC users
as well as for entry-level workstation users.
Intel adds support for Hyper-Threading Technology to the Pentium 4 processor
family. HT Technology allows a single, physical Pentium 4 processor to function as
two logical processor for next generation multi threaded application.
For more information about all the new features Pentium 4 deliver check out the
Intel website at http://www.intel.com
Chipset Components
This board is designed with Intel® 845E chipset. The Intel® 845E chipset consists of
the Memory Controller Hub (MCH and the I/O Controller Hub (ICH4 .


Memory Controller Hub (MCH)
The MCH provides the interconnect between the AGP, DDR SDRAM and the
system logic. It integrates:
- Supports for single processor with a data transfer rate of 400/533/533+MHz.
- Supports dual channel of 200/266/266+ DDR SDRAM up to 2GB.
- 4X 1.5V AGP interface (Only support 1.5V on AGP interface .
- Downstream hub link for access to the ICH4.


I/O Controller Hub (ICH4)
The I/O controller Hub provides the I/O subsystem with access to the rest of the
system. Additionally, it integrates many I/O functions:

Introduction
Page 1-3
- Upstream hub link for access to the MCH
- 2-Channel Ultra ATA/100 Bus Master IDE controller
- USB controller
- SMBus controller
- LPC / Flash BIOS interface
- PCI 2.2 interface
- Integrated System Management Controller
Accelerated Graphics Port (AGP)
The AGP slot on the board is compliant with the new AGP 2.0 specification. This
new specification enhances the functionality of the original AGP specification by
allowing 4X data transfers ( 4 data samples per clock resulting in maximum band-
width of 1GB/s. In addition, it defines 1.5 volt power supply operation. Complying
with this specification, this board supports external AGP-4X cards with Fast Write
Transactions. Only 1.5V AGP cards are supported.
Ultra ATA/66/100
The mainboard provides an Ultra ATA/66/100 Bus Master IDE controller. This
controller supports Ultra ATA/66/100 protocols which are ideal to support demanding
applications such as real-time video, multimedia, and a high performance operating
system. A new IDE cable is required for Ultra ATA/66/100; this cable is an 80-pin
conductor cable which is backward compatible with ATA/33 connectors.
Hardware Monitoring
Hardware monitoring enables you to monitor various aspects of the system operation
and status. The features include CPU temperature, voltage and fan speed in RPMs.
LAN (Optional)
This mainboard is optionally mounted with a LAN chipset. It allows the mainboard to
connect to a local area network by means of a network hub.

Introduction
Page 1-4
Mainboard Form-Factor
This board is designed with ATX form factor - the latest industry standard for
chassis design. The ATX form factor is essentially a Baby-AT baseboard rotated
90 degrees within the chassis enclosure and a new mounting configuration for
the power supply. With these changes the processor is relocated away from the
expansion slots, allowing them all to hold full length add-in cards. ATX defines a
double height aperture to the rear of the chassis which can be used to host a
wide range of onboard I/O. Only the size and position of this aperture is defined,
allowing PC manufacturers to add new I/O features (e.g.; TV input, TV output,
joystick, modem, LAN, audio, etc. to systems. This will help systems integrators
differentiate their products in the marketplace, and better meet your needs.
 By integrating more I/O down onto the board and better positioning the hard
drive and floppy connectors material cost of cables and add-in cards is
reduced.
 By reducing the number of cables and components in the system, manufac-
turing time and inventory holding costs are reduced and reliability will
increase.
 By using an optimized power supply, it's possible to reduce cooling costs
and lower acoustical noise. An ATX power supply, which has a side-
mounted fan, allows direct cooling of the processor and add-in cards making
a secondary fan or active heatsink unnecessary in most system applications.

Power-On/Off (Remote)
This board has a 20-pin ATX power supply connector (Figure 4 . For power
supplies that support the Remote On/Off feature, this should be connected to the
mainboard front panel PW_ON connector for the computer power On/Off button.
This board has been designed with Soft Off" function. You can turn off the system
in two ways: by pressing the front panel power On/Off button or using the "Soft
Off" function that can be controlled by an operating system such as Windows®XP/
ME/2000/98.
Note: For maintaining the DDR SDRAM power during STR (ACP S3) function, it is strongly
recommended to use power supplies that have a +5VSB current of (>=) 2A. Please check the
5VSBs specification printed on the power supplys outer case.
Note: The board requires a minimum of 250 Watt power supply to operate. Your system configura-
tion (amount of memory, add-in cards, peripherals, etc.) may exceed this minimum power
requirement. To ensure that adequate power is provided, use a 300 Watt (or higher) power
supply.

3-1 CPU Installation
Step 1
Open the socket by raising the actuation
lever.
Figure 1
Step 2
Align pin 1 on the CP with pin 1 on
the CP socket as shown in the
illustration above. The CP is keyed to
prevent incorrect insertion. Do not force
the processor into the socket. If it does
not go in easily, check for mis-orienta-
tion and reinsert the CP .
Make sure the processor is fully
inserted into the socket.

Step 4
Apply thermal compound to the top of
the CP and install the heatsink as
shown.
Step
Install the cooling fan assembly. Press
the two clips in the direction of the
arrows shown in Figure 5 to secure the
assembly to the CP socket.
Step 6
Plug the CP fan into the CP fan
connector.
The installation is complete.

NOTES:
 Damage to Intel PentiumTM 4 processors might result if installed with
incorrect CP fan and heatsink assemblies. se Intels design thermal
solution shown in the illustrations above: an active heatsink; an extruded
aluminum heatsink base; and a fan attached to the top of the fin array.
 Apply heatsink thermal compound or paste to the CP to avoid CP
overheating and damage.
 In accordance with Intel Corp. specifications, do not install a CP over
50 times to avoid bending the pins and damaging the CP .
Step 3
Close the socket by lowering and
locking the actuation lever.
