Design Review Checklist
This checklist highlights design considerations that should be reviewed prior to manufacturing a
motherboard that implements an 815EG chipset platform for use with the universal socket 370
platform. This is not a complete list and does not guarantee that a design will function properly.
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.

815EG Chipset Platform Design Guide
• Connect A[31:3]# to GMCH. Leave A[35:32]# as No Connect (not supported
by chipset).
• Connect to GMCH.
• Resistor site for 56 Ω pull-up to VTT placed within 150 mils of GMCH for
debug purpose. Connect to GMCH.
• 33 Ω pull-down resistor to ground
• Terminate to VTT through 86 Ω resistor, decoupled through 22 Ω resistor in
series with 10 pF capacitor to ground. Connect to GMCH. For ITP, also
connect to ITP pin 2 (RESET#) with 240 Ω series resistor.
• 1 k Ω series resistor to RESET#.
