Yosemite DP6 with HD4600

I have very little time to explain what I did, but here is one of the framebuffers that works for me – edit the frame buffers for your setup, follow the links under ‘See also’ for additional information.

Note: 0x0d220003 is just an example – my first Haswell boot was done with 0x0c260000 (see also: Intel HD4600 with full resolution) but I changed it to 0x0a160000 the same day (see _DSM method) but now I let RevoBoot inject 0x04120000.

Tip: VRAM (Video RAM) is not the (UEFI) BIOS settings. That is ‘fStolenMemorySize’. Representing the amount of pre-allocated DRAM memory to support the IGPU in VGA (non-linear) and Native (linear) modes. Not that you need it, because VGA is disabled.

Update

Still not perfect, but this one is getting close:

That should get you started:

1.) No boot loader changes!
2.) No reboot.
3.) No frame buffer crashes.
4.) Boot with single DVI/HDMI/DP connector possible.
5.) Connects to pipe 0.
6.) APPL,boot-display property (Boolean) set to True.
7.) IOFBNeedsRefresh property (Boolean) set to False.

28 thoughts on “Yosemite DP6 with HD4600

  1. Still no luck for me, system keeps crashing @boot. Screen gets wired followed by a reboot.

    I’ve tried your DP5 and DP6 Framebuffer using your script.

    My Configuration: i4570S = HD4600, GA Z87X-UD3H, Screen on DP (no DVI available)

    thx for your efforts, maybe there is a way I can help you to fix this?

    • Ok. Let me add three frame buffer configurations with a single DVI, HDMI and DP connector setup… Done.

      Are you booting your hardware in single user (-s) mode? If yes remove it to see if that helps.

      Additionally. My frame buffers are setup for the least amount of memory (32 MB) in the (UEFI) BIOS, and you cannot use 64 MB or greater with a 32 MB frame buffer configuration. You have to change the blue value (00 00 00 02) but be aware that doing this also changes some memory locations in the ACPI tables. Just in case the boot loader loads the DSDT.aml 😉

      • No I don’t use single user, with mavericks everything is working fine (using ozmosis uefi and a special dsdt).

        Yes, Framebuffer Size is set to 64MB, but I will try 32MB also. Will be home on monday and check with your newest settings.
        They should work for PB2 I think?!

    • No. I never have and never will share or publish Apple files. Not here not anywhere. What I do here is to share information and scripts that I wrote. That is all what I have to offer. Nothing more. Nothing less.

      More importantly. Your motherboard port configuration is most likely different than what I use, and thus you have to do the work yourself.

      • Okay, I’ve tried again on Yosemite PB2 and it is working now! There are some small glitches while the windows manager starts (not as smooth as on my MBPr) but everything is working.

        Sound seems to be toleda’s business *g* I think we need a new Framebuffer patch for DP audio. The one from Mavericks is not working anymore.

        Have a nice!

    • There are two data sections in the script:

      0x0d220003) FACTORY_PLATFORM_INFO=”0:
      0x0d220003) PATCHED_PLATFORM_INFO=”0:

      And you forgot, apparently, to patch the second one so there is nothing to patch.

  2. How i Use it for my 0x04128086 can you give any example Iused all options but still says Fectory/Patch data match nothing to patch.

    • Sorry. Was busy with another project, but there was a typo/small error in function _dumpConnectorData that I fixed in version 1.8 Please try this version and see if that solves the problem.

      Do you have Xcode installed?

      You only patch the data under 0x0d220003) PATCHED_PLATFORM_INFO=”0: and not the data under 0x0d220003) FACTORY_PLATFORM_INFO=”0: ?

  3. Pingback: New repository for AppleIntelInfo.kext | Pike's Universum

  4. thanks piker alpha , You are the genius ….. Finally patched in Azul Hex by your description and now work …….

    thanks bro. thank you so much ………..

  5. Thanks Pike.
    No more 10.10 reboot now for my NUC when booting from primary display.
    Am using this as patched fb and connecting via HDMI (port 5 FB1) and DP(port 6 FB2) FBs 0 and 3 are not used. Both hdmi/dp Audio works too:
    0300220D 00030403 00000002 00003001 00009000 00000060 99140000 99140000 00000000 00000000 00000800 00010000 30000000 01050800 00080000 06000000 02040A00 00040000 40000000 03060900 00040000 87000000 D6000000 05050000 04000000 00000000 00000000 00000000 00000000 00000000 00000000 0E000000
    Only issues are: 1. slight screen distortion during final boot phase in 10.10 and 2. cannot use this injecting via Clover as it screws up my 10.9 boot

    • Thank you for sharing this here. Can you tell me a little bit more about the ‘slight screen distortion’? Is that at the bottom of the screen or somewhere else, and when is it doing that? When the progress bar is shown or afterwards?

      • It is where the IOGraphicsFamily kext kicks in. A non distorted progress bar appears centrally (without Apple logo) while background distortion is multiple distorted versions of Apple/progress bar distributed horizontally across screen. i.e. same distortion as used to occur just prior to reboot – except there is no reboot now and all continues fine when desktop takes over.

    • Let me start with a pseudo code snippet:

      if (__private->needsInit == 2) {
      // AAPL,boot-display is set and IOFBNeedsRefresh == false
      // Don't clear the screen and skip drawing the logo
      } else {
      // AAPL,boot-display may be set, but IOFBNeedsRefresh == true
      // Clear screen and draw logo
      }

      And what this workaround does is that it makes it skip the first check. Not what I want. I want the frame buffer (binary) to be patched in a way that it meets the conditions required by the IOGraphicsFamily.kext binary. That is also why I haven’t mentioned this workaround, because it doesn’t actually solve the problem, but hides it.

      However. Since there is no such patch at this moment, the workaround works 😉

  6. Piker You putted before info. about Azul

    For fFramebufferMemorySize

    00 00 00 01 = 0x01000000 = 16 MB
    00 00 00 02 = 0x02000000 = 32 MB
    00 00 00 04 = 0x04000000 = 64 MB
    00 00 00 06 = 0x06000000 = 96 MB
    00 00 00 08 = 0x08000000 = 128 MB
    00 00 00 10 = 0x10000000 = 256 MB
    00 00 00 18 = 0x18000000 = 384 MB
    00 00 00 20 = 0x20000000 = 512 MB
    00 00 00 30 = 0x30000000 = 768 MB
    00 00 00 40 = 0x40000000 = 1024 MB
    00 00 00 60 = 0x60000000 = 1536 MB
    00 00 00 80 = 0x80000000 = 2048 MB

    Now can you give me table like this for VRAM ?
    for 10.10 DP6

    And can you tell me how you calculate this ??? Please ……
