About This Design Guide - Intel 440GX Design Manual

Introduction
This document provides design guidelines for developing Intel
440GX AGPset based systems. Motherboard and memory subsystem design guidelines are
covered. Special design recommendations and concerns are presented. Likely design issues have
been identified and included here in a checklist format to alleviate problems during the debug
phase. One reference board design is presented:
•
Dual Processor (DP), 4 DIMM design
These designs use the Intel
82443GX Host Bridge and the 82371EB PIIX4E.
®
Note: The Intel
processor will also be offered as an Intel boxed processor, intended for system integrators who
build systems from motherboards and other components. Some hints for early debug problems are
also included.

About This Design Guide

This document is intended for hardware design engineers who are experienced in the design of PC
motherboards or memory subsystem. This document is organized as follows:
Chapter 1, Introduction. This chapter provides an overview of the features on reference design.
Chapter 1 also provides a general component overview of the Intel
Intel 440GX AGPset. The Wired for Management Initiative is also discussed which is an Intel
initiative to improve the manageability of desktop, mobile, and server systems. This chapter also
provides design recommendations which Intel feels will provide flexibility to cover a broader range
of products within a market segment.
Chapter 2, Motherboard Layout and Routing Guidelines. This Chapter provides detailed
layout, routing, and placement guidelines for the motherboard and memory subsystem. Design
guidelines for each bus (Host GTL+, PCI, DRAM, and AGP) are covered. This chapter provides
details on design methodology, Timing analysis, simulation, and design validation.
Chapter 3, Design Checklist. This chapter provides a design checklist that is intended to be used
when reviewing your Intel
AGPset reference design provided in this Design Guide. Items which have been found to be
incorrect on previous designs are provided as a tool to allow the quick debug of Intel
processor based systems.
Chapter 4, Debug Recommendations. This chapter presents debug recommendations that may
assist in the development of the Intel
utilizing them. This chapter also provides tool information, logic suggestions, technical support
options, and a summary of the problems which have been found to be associated with system
debug.
Chapter 5, Third Party Vendor Information. This chapter includes information regarding
various third-party vendors who provide products to support the Intel
Appendix A, Intel
schematics used in the single processor and dual processor reference designs.
