System Overview

This board is designed with Intel

845PE chipset. The Intel

845PE chipset

includes MCH(FW82845PE), ICH4(FW82801DB) and FWH three chips. The

Intel

845PE chipset is designed for Intels FC-PGA2 socket 478 package

architecture and support the 4X capability of the AGP 2.0 Interface Specification.

A new chipset component interconnect, the hub interface, is designed into the

Intel

845PE chipset to provide more efficient communication between chipset

components.

Support of AGP 4X, 266/333MHz DDR SDRAM and the hub interface provides a

balanced system architecture for the Pentium

4 in the Socket 478 architecture

processor minimizing bottlenecks and increasing system performance. By

increasing memory bandwidth to 2.128GB/s through the use of AGP 4X, the

Intel

845PE chipset will deliver the data throughput necessary to take advantage

of the high performance provided by the powerful Pentium

4 in the Socket 478

architecture processor.

The Intel

845PE chipset architecture removes the requirement for the ISA

expansion bus that was traditionally integrated into the I/O subsystem of Intel

chipsets. This removes many of the conflicts experienced when installing

hardware and drivers into legacy ISA systems. The elimination of ISA will provide

true plug-and play for the Intel

845PE platform.

Intel

845PE chipset contains three core components: the Memory Controller

Hub (MCH), the I/O Controller Hub (ICH4) and the Firmware Hub (FWH). The

MCH integrates the data transfer rate of 400/533MHz, Pentium

4 processor bus

controller, AGP 2.0 controller, 266/333MHz DDR SDRAM controller and a high-

speed hub interface for communication with the ICH4. The ICH4 integrates an

UltraATA/66/100 controller, USB host controller, LPC interface controller, FWH

interface controller, PCI interface controller, and a hub interface for communica-

tion with the MCH. The Intel

845PE chipset will provide the data buffering and

interface arbitration required to ensure that system interfaces operate efficiently

and provide the system bandwidth necessary to obtain peak performance the

Pentium

4 in the Socket 478 architecture.
