    How Do I enable SMRAM on the Core I7

    Community Member


           I'm working on a Core-i7 - QM57 design that I'm getting a small BIOS up and running on. I see in the Intel Docs 253668.pdf mention of the D_LCK bit to enable access to the SMRAM. But what I can't find is where the register is on this part. I know that in prior parts it was at Bus Device Function 0,0,0 and offset 9d, but this is reserved on the I7. What am I missing ?
