Introduction
This design guide provides motherboard design guidelines for Intel
These design guidelines have been developed to ensure maximum flexibility for board designers
while reducing the risk of board related issues. In addition to design guidelines, this document
discusses Intel
The debug recommendations should be consulted when debugging an Intel
system; however, the debug recommendations should be understood before completing board
design to ensure that the debug port, in addition to other debug features, will be implemented
correctly.

About This Design Guide
This design guide is intended for hardware designers who are experienced with PC architectures
and board design. The design guide assumes that the designer has a working knowledge of the
vocabulary and practices of PC hardware design.

Chapter 4, "Layout and Routing
motherboard layout and routing guidelines, except for processor-specific layout guidelines.
The motherboard functional units are covered (e.g., chipset component placement, system bus
routing, system memory layout, display cache interface, hub interface, IDE, AC'97, USB,
interrupts, SMBUS, PCD, LPC/FWH Flash BIOS, and RTC). For the PGA370 processor
specific layout guidelines, refer to
