815 Chipset Platform Design Guide 13
1 Introduction
This design guide organizes Intel’s design recommendations for the Intel ® 815 chipset platform for
use with the Universal Socket 370. In addition to providing motherboard design recommendations
(e.g., layout and routing guidelines), this document also addresses system design issues
(e.g., thermal requirements).
This document contains design recommendations, board schematics, debug recommendations, and
a system checklist. These design guidelines have been developed to ensure maximum flexibility
for board designers, while reducing the risk of board-related issues.
Board designers can use the schematics in Appendix A: Customer Reference Board (CRB) as a
reference. While the schematics cover specific designs, the core schematics will remain the same
for most Intel 815 chipset designs for use with the Universal Socket 370. Consult the debug
recommendations when debugging your design. However, these debug recommendations should
be understood before completing board design, to ensure that the debug port, in addition to other
debug features, are implemented correctly.
The Intel 815 chipset platform supports the following processors:
•
Intel
®
Pentium
®
III processor based on 0.18 micron technology (CPUID = 068xh).
•
Intel ® Celeron™ processor based on 0.18 micron technology (CPUID = 068xh). This applies
to Celeron 533A MHz and
≥
566 MHz processors
•
Future 0.13 micron socket 370 processors
Note: The system bus speed supported by the design is based on the capabilities of the processor,
chipset, and clock driver.
Note: The Intel 815 chipset for use with the universal socket 370 is not compatible with the
Intel
®
Pentium
®
II processor (CPUID = 066xh) 370-pin socket.
