If you are booting in EFI mode, does it work if you boot in legacy bios mode? Since it's a mac, it probably requires some mac specific hack.
I'm booting via EFI stub. I'm not sure how to boot the bios emulation mode. Is it possible to plug in a usb stick with a "normal" live system to boot in emulation mode?
