First of all big thank to Micky1979 to propose and test this feature on his Intel HD4000
(Also this feature will be included in the next "coming soon" Pandora's Box (Beta2+)

OK let's start:

Last week, I wrote in Chameleon the option to inject via org.chameleon.Boot.plis the AAPL,ig-platform-id and PRESERVING the last commit feature provided by meklort and cosmo1t on the gma.c file.

Micky1979 was propose me to add a key for the AAPL,ig-platform-id in o.c.B.p to provide custom value instead of classic DSDT or EFI strings.
We test it and works with out DSDT and EFI string And now we need few testers to confirm it work, also we need to make sure it works on different Intel HD 4000 cards.

What benefit?

• No more DSDT edits!
  
• No more EFI Strings!
  
• No more Headache!
  
• Easy change the FB "personality"!

How use this feature?

• This feature was already implemented in my branch of Chameleon (Enoch).
  At this link the latest compiled Enoch binaries: Enoch 2210 updated to 2231, now available here >> Enoch Bootloader
  Install it.
  
• Disable any kind of enabler, DSDT injection, injector or device-properties you're currently using.
  
• In org.chameleon.Boot.plist set GraphicsEnabler = Yes
  
• Add the key HD4K-ig = some value between 0 and 11 into your o.c.B.p aka org.chameleon.Boot.plist (/Extra/org.chameleon.Boot.plist)
  Example: HD4k-ig = 4
  Will be inject the value 01660004 for the AAPL,ig-platform-id

  The possible value for the HD4K-ig key are:
  HD4K-ig=0  set ig 01660000 // Mobile  4 Ports, 1 LVDS (Display Notebook) e 3 Display Port
  HD4K-ig=1  set ig 01660001 // Mobile  4 Ports, 1 LVDS (Display Notebook), 1 HDMI e 2 Display Port
  HD4K-ig=2  set ig 01660002 // Mobile  1 Port, LVDS (Display Notebook)
  HD4K-ig=3  set ig 01660003 // Mobile  4 Ports, 1 LVDS (Display Notebook), 1 HDMI e 2 Display Port
  HD4K-ig=4  set ig 01660004 // Mobile  1 Port, LVDS (Display Notebook)
  HD4K-ig=5  set ig 01620005 // Desktop 3 Display Ports
  HD4K-ig=6  set ig 01620006 // Desktop 0 Port (don't use it with the original kext)
  HD4K-ig=7  set ig 01620007 // Desktop 0 Port (don't use it with the original kext)
  HD4K-ig=8  set ig 01660008 // Mobile  3 Ports, 1 LVDS (Display Notebook) e 2 Display Port
  HD4K-ig=9  set ig 01660009 // Mobile  3 Ports, 1 LVDS (Display Notebook) e 2 Display Port
  HD4K-ig=10 set ig 0166000a // Mobile  3 Ports, 2 Display Port e 1 HDMI
  HD4K-ig=11 set ig 0166000b // Mobile  3 Ports, 3 Porte, 2 Display Port e 1 HDMI
  
• Also there is the possibility to use the HDAEnable.dylib to Inject AUDIO layout-id value (hexadecimal)
  Note: I wrote this module more than 6 months ago (Still a work in progress) but is functionally, soon I upload a new version (more easy with decimal value).

F.A.Q.

• Q. What happens if I forgot to add the HD4K-ig key in org.chameleon.Boot.plist?
  A. The bootloader assign the default value done by the code above: (by meklort and cosmo1t)
  
  Spoiler

  else if(model == (char*)&"HD Graphics 4000" ||
  model == (char*)&"HD Graphics 4000 Mobile" ||
  model == (char*)&"HD Graphics 2500" ||
  model == (char*)&"HD Graphics 2500 Mobile")
  {
  uint32_t ram = (((getVBEVideoRam() + 512) / 1024) + 512) / 1024;
  uint32_t ig_platform_id;
  
  switch (ram)
  {
  case 96:
  ig_platform_id = 0x01660000; // 96mb
  break;
  
  case 64:
  ig_platform_id = 0x01660009; // 64mb
  break;
  
  case 32:
  ig_platform_id = 0x01620005; // 32mb
  break;
  default:
  printf("Please specify 96, 64, or 32MB RAM for the HD4000 in the bios.\n"
  "The selected %dMB RAM configuration is not supported for the HD4000.\n", ram);
  pause();
  return false; // Exit early before the AAPL,ig-platform-id property is set.
  break;
  }
  
  devprop_add_value(device, "built-in", &BuiltIn, 1);
  devprop_add_value(device, "class-code", ClassFix, 4);
  devprop_add_value(device, "hda-gfx", (uint8_t *)"onboard-1", 10);
  devprop_add_value(device, "AAPL,ig-platform-id", (uint8_t*)&ig_platform_id, 4);
  }
  
  

  so if you don't set any values, by default the booter assign a specific ig based on RAM value:
  96MB=01660000
  64MB=01660009
  32MB=01620005

I would like to outline a few things:

• This isn't a HOW TO get your card working, this is a request for testing.
  
• Don't ask how to install the booter, how to use or add a given booter flag or how to run an update, if you don't know how to do that yourself, then this isn't for you, yet, learn that elsewhere, and you're more than welcome here.
  
• I don't take responsibility for any damage this may cause, so take your precautions before you use this.
  
• The source code will be committed/released when I have accumulated feedback

Requirements:

• A Intel HD4000.

How and what to report:

• Disable any kind of enabler,DSDT injection, injector or device-properties you're currently using.
  
• Save an bdmesg dump (From terminal or from Chameleon Wizard bdmesg’s TAB).
  
• Report any observations or comments.
  
• Include a screenshot of the Graphics tab from System Profiler when reporting.

Thanks all. ErmaC

Una curiosità che ho trovato sul web...

In parole spicciole la Apple donerà una cospicua somma di denaro (14 miliardi di dollari) nel progetto della NASA per
la raccolta di "pietre" spaziali (asteroid mining) con l'esclusiva di poterne utilizzare le materie prime...

... o dobbiamo aspettarci un nuovo Apple Store sulla MIR...

Ciao stavo gironzolando in cerca di notizie su "discovery" e mi sono imbattuto in questa novità mostruosamente recente
(28 novembre 2012)... Speriamo che rientri nella norma il più presto possibile...
