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 the Pentium 4 delivers check out
the Intel website at http://www.intel.com
Chipset Components
This board is designed with Intel® 875P (Canterwood chipset. The Intel® 875P chipset
consists of the Memory Controller Hub (MCH , and the I/O Controller Hub (ICH5/R .


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 533/800MHz.
- Supports dual channel of 333/400 DDR SDRAM up to 4GB.
- 8X/4X 1.5V AGP interface (Only support 1.5V on AGP interface .
- Downstream hub link for access to the ICH5/R.


I/O Controller Hub (ICH5/R)
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:
- Upstream hub link for access to the MCH

Introduction

- 2-Channel Ultra ATA/100 Bus Master IDE controller
- USB controller
- SMBus controller
- LPC / Flash BIOS interface
- PCI 2.3 interface
- Integrated System Management Controller
Accelerated Graphics Port (AGP)
The AGP slot on the board is compliant with the new AGP 3.0 specification. This
new specification enhances the functionality of the original AGP specification by
allowing 8X data transfers ( 8 data samples per clock resulting in maximum band-
width of 2.1GB/s. In addition, it defines 1.5 volt power supply operation. Complying
with this specification, this board supports external AGP-8X/4X cards with Fast
Write Transactions. Only 1.5V AGP cards are supported.
Ultra ATA/66/100
The ICH5/R provides an Ultra ATA/66/100 Bus Master IDE controller. This controller
supports Ultra ATA/66/100 protocols which are ideal to support demanding applica-
tions 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 LAN chip. It allows the mainboard to
connect to a local area network by means of a network hub.

Introduction
Page 1-4
Serial ATA
The evolutionary serial ATA interface replaces the standard parallel ATA physical
storage interface. The serial ATA specification provides scalability and allows
future enhancements to the computing platform. Serial technology overcomes
performance limits of parallel interface architecture, meeting the escalating need for
faster data throughput in servers and storage devices.
Serial ATA is completely software compatible with parallel ATA, requiring no
modification to your operating system. The serial ATA interface cable requires lower
voltages and uses smaller cable connectors, providing ease of installation. You can
easily upgrade storage devices that are compatible with the serial ATA interface
specification.

Introduction

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 and a 4-pin ATX12V 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.
The 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 (incorporated in the mainboards onboard circuit controller 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 that has been printed on the
power supplys outer case.
Note: The board requires a minimum of 250 Watt power supply to operate. Your
system configuration (amount of memory, add-in cards, peripherals, etc.) may
exceed the minimum power requirement but to ensure that adequate power is
provided, use a 300 Watt (or greater) power supply. Also your power supply
must support 4-pin ATX 12V connector.
I/O Shield Connector
The board is equipped with an I/O back panel (Figure 3 . Ensure that your computer
case has the appropriate I/O cutout.
