README

Because almost everything was changed, improved, re-factored and bug-fixed since last release,
here are highlighted the most important ones for the end-user:

======================================================

 'Key'                        || 'Value' || 'Note/Example'
==============================||=========||==================================
 AcpiLoaderMode               || INTEGER || Control ACPI Loader
 UserInterface                || BOOLEAN || Display User Interface/GUI
 TimeOut                      || INTEGER || Time-out In Seconds
 DisableAtiInjection          || BOOLEAN || De/activate ATI GFX device property injection
 AtiFramebuffer               || STRING  || Name of the specific ATI framebuffer
 DisableNvidaInjection        || BOOLEAN || De/activate Nvidia GFX device property injection

Examples:
=========

  !! Note on VoodooHDA, it covers ONLY the onboard codec and is enabled for the moment only for ALC892/ALC1150 !!
  !! For discrete graphics HDMI/DP audio AppleHDA is used instead. Those who use internal GPU (IGPU) only will !!
  !! have to disable VoodooHda and use AppleHda for HDMI/DP audio                                              !!

  To Disable loading VoodooHda.kext from Firmware

    sudo nvram 1F8E0C02-58A9-4E34-AE22-2B63745FA101:DisableVoodooHda=%01

  To Enable loading VoodooHda.kext from Firmware

    sudo nvram 1F8E0C02-58A9-4E34-AE22-2B63745FA101:DisableVoodooHda=%00


 Changing ATI Framebuffers
=========================

  sudo nvram 1F8E0C02-58A9-4E34-AE22-2B63745FA101:AtiFramebuffer=Futomaki

 Or based on VendorSubsystemId

  sudo nvram 1F8E0C02-58A9-4E34-AE22-2B63745FA101:AtiFramebuffer10029440=Futomaki

 Or based on pci addressing

  sudo nvram 1F8E0C02-58A9-4E34-AE22-2B63745FA101:AtiFramebuffer00.01.00=Futomaki

Changing AAPL,ig-platform-id
============================

  sudo nvram 1F8E0C02-58A9-4E34-AE22-2B63745FA101:AAPL,ig-platform-id=0x01620005

Changing AcpiLoader Mode
============================

  Add The Following Values Together For Default Acpi Loader Mode

  ACPI_LOADER_MODE_DISABLE        0x00000000
  ACPI_LOADER_MODE_ENABLE         0x00000001
  ACPI_LOADER_MODE_DUMP           0x00000002
  ACPI_LOADER_MODE_WINDOWS        0x00000008
  ACPI_LOADER_MODE_UPDATE_LEGACY  0x00000040

  Default Value : ACPI_LOADER_MODE_ENABLE | ACPI_LOADER_MODE_DARWIN | ACPI_LOADER_MODE_UPDATE_LEGACY = 0x45

  To Change

  sudo nvram 1F8E0C02-58A9-4E34-AE22-2B63745FA101:AcpiLoaderMode=0x45

Note: They can also be controlled by using Defaults.plist placed on boot hard-drive efi system partition and path is /EFI/OZ/Defaults.plist, see bellow for example.

WARNING! Defaults.plist will override the one found in firmware and values are used only if variables are not already added.
For example if you want to set BiosVersion using Defaults.plist and was already set by Defaults from Firmware, you will need
to do a 4 finger NVRAM reset or delete the BiosVersion variable from shell, for the new one to be used.
