can you please tell me. Was it with some debugger, or how.
I found the Napa SZ registers by a long process of trial and error. First I made seven files, each having a [0000] -> [0001] value change in one of the seven sections (0000-00FF,0100-01FF, ... , 0600-06FF) and sequentially wrote them to the NVRAM and noted the changes. If a significant change had occured in one of the seven sections, such as a BSOD, indicating that AHCI was enabled, or a change in the VT.iso results, I continued to use a divide and conquer type approach in that section until I had narrowed it down to the right locations. Since the SZ registers are around the 0100-03FF range, you may want to try searching in that area first.
