Thanks' a lot. I built the new grub.efi as you suggested and now I'm able to boot using efi. Now for the next problems ;-) I do not see any messages while booting.

AHA! Well, confusion rises ... So, my grub-legacy configuration uses none of video or vga options...is there a way to test if efifb is working with my kernel, anyway? I think a hint where to search should be enough. Just to get this right: If I use any framebuffer beside efifb, I need to load a video bios?

I tried changing my menu entries vie 'e' in the menu. Nothing works,
only with video=efifb, without noefi and all other sorts of
combinations. Could it be that I need some different video=...?
The last line of my boot-attempts is always something like "Video line
length".
greetings,
Stefan

Thanks for the tip,
This is my grub-mkimage line:
grub-mkimage -o grub.efi part_gpt hfsplus fat ext2 normal chain boot
configfile part_apple appleldr
Next I try to include all modules.

Grub2 and Efi (MacBook 5,1)
Hi Grub2 fans!
I'm trying to get Grub2 working on a Efi platform (MacBook 5,1).
In version 1.96 I get a menu with a working MacOSX entry, but linux
won't boot. I just get some output which looks like data for the video
card, than the system hangs.
With todays SVN version (which does not compile configured without
--disable-werror) I just get a rescue shell with loads of messages on
unknown commands.
By the way, how do I scroll up to the topmost message in grub-shell?
Here is my grub.cfg:
timeout=10
menuentry "Gentoo Linux 3 NOAGB NOEFI" {
root=(hd1,3)
loadbios /boot/vbios.bin /boot/int10.bin
linux /boot/kernel-2.6.27-gentoo-r8-n root=/dev/sda4 video=efifb
agp=off noefi
}
menuentry "MacOSX" {
root=(hd1,2)
chainloader /usr/standalone/i386/boot.efi
}
Has anybody a clue?
kind regards,
Stefan
