They are on the supplied Openrd DEV kit V1.0 CDrom.
You should have had a cd supplied with your open rd
If not, get one from your retailer.
By the way.... If you definitely have a client board, then the newer V2.0 Cdrom is no use. The schematics on it have been updated for the Ultimate.
If you cannot obtain the cd, pm me with an upload location and I will upload you the original schematic pdf, not the complete devkit
