Hmm. It should not require anything more than a yellow book.
Basically Intel does not like to publicly document all of their
registers and occasionally that is the problem.

The thing not to expect is for any vendor to hold your hand.

Where I usually start is with a hard coded configuration for
a particular DIMM configuration.  And I will verify that the
DIMMs are known good so I don't have to worry about the hardware.

Where are you at in this process and what problems are you seeing?
