board-id drama take III. Black boot.efi

Sorry for the poor image quality. Hope this helps.

 

[Pike R. Alpha]

Sorry for the poor image quality. Hope this helps.

Nope. Still not detected. What a drama (lol).

Edit: Thanks. Was in a hurry and forgot to say thanks. Found a small var mixup. Let's hope that this is it.

Or like this. Black boot.efi

To everyone interested in this project:

[P]eople must be aware that [this and other] interim future versions are NOT intended as a replacement for the official repository versions. Until further notice, those of you who want to use Pike's boot.efi ought to go to http://piker-alpha.github.io/macosxbootloader/ and download either the "black" version or the "grey" one, according to your particular preference (the change is purely cosmetic; otherwise, they are exactly the same; the choice is irrelevant as far as the operating system is concerned). Pike alone will decide when such repository versions will be updated with a newer version.

Please, notice that the [enclosed and other] upcoming experimental versions might contain bugs that could cripple your ability to boot your old Mac. So, unless you are absolutely certain of what you are doing and know how to reverse such undesirable situations, KEEP AWAY FROM THEM. In general terms, [these] versions ARE NOT FOR YOU!

Tested 539f9f55a9e274bea96ac940af0c134414d1b141 on MBP2,2:
· patched Installer (Hennesie-Guide) - hangs still after "Waiting for DSMOS"
· patched Installer (createinstallmedia) - boots into Installer-GUI, but I'm not able to select 'Install OS X' from the Utilities window, the Continue-button remains grey
· transferred OSX - boots into Desktop, but still Kernel Panic after some minutes.

No problem, glad to be able to help in some small way!

But I'm afraid that must not have been it. Same result, won't bother posting a photo of the debug output, as it's identical to the previous photo I posted. Sorry...

 

[splifingate]

Commit 539f9f55 compiled, usual suspects replaced, successful boot into createinstall environment, and Install OSX tells me that ElCap is already installed.

Teh Song remains teh same....

Thanks. Table length is wrong and due to this error, the memory allocation also fails. At least now we know where to look.

Edit: At this point my only concern is the debug output, which is dead wrong at the moment. Rest of the code works in a command line tool.

Your SMBIOS table length should report 1677

With this build, I get no debug output at all. Sits at a black screen with a "_" cursor for about 20 seconds, flash of gray screen, then back to black screen with the "_" character for a few more seconds, followed by a folder icon with a "?" inside.

Thought my USB stick might be corrupt, but by going back to the previous boot.efi build, I got the debug output. After coming back to a7347d... it repeated the black screen followed by ? folder icon.

[Pike R. Alpha]

Thanks guys. This is interesting. Right at a point where it shouldn't fail. New commit available for compilation.

Sorry. I was busy trying to solve this issue when I did a pre-mature (or two) commit(s). Latest one should be better. SMBIOS GUID detection is now working and the memcpy instructions should now also be fine. Thanks!

@mikeboss, Thanks.
