Hi,
Thanks for the idea, here fat grub.efi tested ok on imac8,1 (64) and
MacBook2,1 (32), using working grub32.efi and grub64.efi with their
preloaded modules.
./fatglue.py grub2202f.efi grub2202-32.efi grub2202-64.efi
compile and fatglue were all done in OSX10.5.6.
Debian sid 2.6.29.1-amd64 boots for me on imac8,1 using
menuentry "sid amd64 fbdev sda9" {
fakebios
root=hd0,9
linux /vmlinuz root=/dev/sda9 video=efifb noefi
initrd /initrd.img
}
