Morphos With a delay of a few days, Genesi has released the schematics to its Pegasos Rev.2b5 motherboard. You can download it from here, but you'll need to sign up (free) on They even blogged about it, stating: "If you are just along for the ride you can stop reading now. Your challenge: be the best you can be. That is the competition. We are in the human line that stretches behind and beyond us. We all can have a role to play. To participate we have to start within ourselves, find firm footing, and launch into the world around us."

Only a Schematic

This is only a schematic, as far as I can tell. The real art with modern mobo high-speed design is in the layout. Reference design schematics are very often made available for free from chip producers, since they DO want to encourage you to use their chips. The pinouts on modern digital chips are not really that mystereous; it is the internal firmware or logic that kills designers or Open Source driver developers.

IBM had open-sourced their "Yellow-Knife" PPC motherboard design many years ago, and a few of us in the old OpenPPC project quickly discovered that the schematics are not even one fifth of the battle.

Last year I did a commercial DSP board design, and the FCC certification took a lot longer than the schematic.
