1-2 Chipset Overview

Intel’s E7221 (Copper River) chipset, designed for the server market, con-

sists of the following components: the Graphics Memory Controller Hub

(GMCH), Intel PCI-X Hub (PXH-V), and Intel I/O Controller Hub (ICH6R). The

E7221 (Copper River) chipset provides the performance and feature-set

required for the entry level single-processor server solutions.

Graphics Memory Controller Hub (GMCH)

The function of the GMCH is to manage the data flow between five inter-

faces: Processor/Host interface (FSB), System Memory Interface (DRAM

controller), PCI Express Interface, Direct Media Interface (DMI) and PXH-V

Interface. The GMCH is optimized for the Prescott processors in an

LGA775 Package. It supports one or two channels of unbuffered, ECC/Non

ECC DDR2 533/400 SDRAM.

The ACPI component provides the data buffering and interface arbitration

required to ensure that system interfaces operate efficiently. The Direct

Media Interface (DMI) is a point-to-point interconnect between the Copper

River GMCH and the ICH6.

Intel ICH6R System Features

The I/O Controller Hub provides the I/O subsystem with access to the rest

of the system. Functions and capabilities include:

*PCI Express Base Specification, Rev. 1.0a-compliant

*PCI 2.3

*ACPI Power Management Logic Support

*USB host interface

*Enhanced DMA Controller

*System Management Bus

*Low Pin Count (LPC) Interface

*Firmware Hub (FWH) Interface

Graphics Features/Display

The Copper River GMCH provides an integrated server-quality onboard

graphics.
