EFI Boot on MacPro

[Ziling Zhao]

I'm trying to get grub2 working on a Mac Pro using pure EFI.

So, I've mucked around a bit and grub is loading. I can have it load the linux image as well, but it freezes soon after.

Output is:

  Booting 'Gentoo'
   
     [Linux-bzImage, setup=0x2c00, size=0x2ff4701]
Video mode: address@hidden
Video frame buffer: f0000000

-- Then it freezes --

I seeded a bunch of grub_printf statements to see where it dies, and it seems like it calls grub_machine_fini() (grub_loader_noreturn) is set to 1. However, it doesn't seem to get back to grub_cmd_boot, which is calling grub_loader_boot.

Anybody know what this is doing?

I've heard that people have successfully gotten non rEFItted makes to boot Linux, can anybody confirm this?


I compiled the grub2 stuff with "./configure --with-platform=efi --target=i386", this is grub trunk.
