1-2 Chipset Overview
Intel’s E7221 (Copper River) chipset, designed for the server market, consists
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 fl ow between fi ve interfaces:
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 effi ciently. 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 Specifi cation, 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 E7221 Copper River GMCH provides an integrated server-quality onboard
graphics.
