      These are the Original iMac17,1 Firmware 0105_B20 ACPI Tables.
      They have been extracted from the firmware file provided in 10.12.4 update, so they are clean and unloaded.
      All tables are available in hex cut/new file/paste order so they are untouched and unloaded.
      I believe these files can serve to better study Skylake architecture implementation in Sierra.
