Actually, if I'm not mistaken, you only need to cover the HT hole with one MTRR - the rest remains WB. And in order the mask bits to work, we could make it a little bigger - we waste some memory but that's nothing in comparison to the MCE. You might need to talk to hw guys about the feasibility of this deal though. Thanks. -- Regards/Gruss, Boris. Sent from a fat crate under my desk.
