13 System Design Checklist
13.1 Design Review Checklist
Introduction
This checklist highlights design considerations that should be reviewed prior to manufacturing a
motherboard that implements an Intel 815 chipset platform for use with the universal socket 370.
This is not a complete list and does not guarantee that a design will function properly. For items
other than those in the following text, refer to the latest revision of the design guide for more-
detailed instructions regarding motherboard design.
Design Checklist Summary
The following set of tables provides design considerations for the various portions of a design.
Each table describes one of those portions and is titled accordingly. Contact your Intel Field
Representative in the event of questions or issues regarding the interpretation of the information in
these tables.
