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:
Start-up HotKeys
================
'Function' || 'Shortcut' || 'Notes'
===================||======================||=========
Disable Ozmosis || Escape || Press at start-up, screen will flash red to indicate Ozmosis is disabled.
Reset NVRAM || Option+Command+P+R || From F12 menu, Ozmosis GUI, Shell or BIOS Setup.
Start Ozmosis GUI || Option/Home || It can be controlled with mouse only for now.
Safe Boot Mode || Shift ||
Verbose Mode || Command+V ||
Single-User Mode || Command+S ||
32 Bit Boot Mode || 3+2 || Start Up In 32 Bit Mode
64 Bit Boot Mode || 6+4 || Start Up In 64 Bit Mode
Mac/PC Keyboard Legend
======================
'Mac' Key || 'PC' Key
Option || Alt
Command || WinLogo
Added the ability to control graphics and audio injection using NVRAM variables, complete list of variables:
Default Settings 1F8E0C02-58A9-4E34-AE22-2B63745FA101
======================================================
'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
DisableIntelInjection || BOOLEAN || De/activate Intel GFX device property injection
DisableVoodooHda || BOOLEAN || Disables loading VoodooHDA from firmware
EnableVoodooHdaInternalSpdif || BOOLEAN || Enable/Disable onboard S/PDIF header when using VoodooHDA from firmware
DisableBootEntriesFilter || BOOLEAN || Disables filtering of firmware generated boot entries
AAPL,snb_platform_id || INTEGER ||
AAPL,ig-platform-id || INTEGER ||
BootEntryTemplate || STRING || $label $guid
DarwinDiskTemplate || STRING || $label $platform $major $minor $build
DarwinRecoveryDiskTemplate || STRING || $label $platform $major $minor $build
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.
