Re: EFI Boot on MacPro

[peter cros]

I tried your 64bit grub.efi, same result - hangs at start (on current imac8,1).
I wonder if you have tested on the current MacBook or MacBook Pro, perhaps Apple have made another change. Also I dont have any info on previous Imac models. 

I was able to get a return via grub_main() only by excluding both of the movq lines in the code before the call. Either one hangs it. 

Looks to be a problem with grub_efi_image_handle and grub_efi_system_table?
-------------------
kern/x86_64/efi/startup.S

codestart:
    call    EXT_C(grub_main)
    ret
-    movq    %rcx, EXT_C(grub_efi_image_handle)
-    movq    %rdx, EXT_C(grub_efi_system_table)
-----------------
kern/main.c

void
grub_main (void)
{
return;
}
---------------------

Is there anything else I can try?

Hi,

This is quite strange, it might be caused by the compiler. You can try
my version of grub.efi:
