Hi,
yes I am compiling grub on a 64 bit kernel and with x86_64 as target (--with-platform=efi --target=x86_64)
Compiling on a 32 bit machine does not succeed because the Xserve 2,1 does not accept 32 bit EFI images.
Best regards,
Chris

Hello
I don't know much about this.
However, you're compiling it on a 64-bit kernel, right?
The limitation you are talking about is the 32-bit 2 64-bit
limitation. 32-bit only supports up to 3.25GB of RAM.
Have you tried compiling it on 32-bit os? That may (for some reason)
fix the problem.
Give it a go.

Subject: Grub2 SVN on 64bit Xserve 2,1
To: address@hidden
Cc: address@hidden
Hello all,
recently, we tried to use Grub2 SVN on a 64bit Apple Xserve (Model
2,1) using EFI and after Bean solved some Xserve specific problems
that were discussed on the Ubuntu forums
(http://ubuntuforums.org/showthread.php?t=995704) someone else finally
managed to boot his Xserve 2,1 model with Grub2.
Ours however, did not boot and we isolated the problem to be a memory
problem: When we plug in 4 GB or more, Grub2 fails (when you finally
type "boot" on the command line, the machine instantly reboots). If we
remove all but 2 GB of RAM, it works and we managed to boot a Debian
kernel. So this seems to be a bug which only appears on this type of
machine with >= 4GB of RAM.
Unfortunately, I haven't found a way yet to get any debug output for
you from the machine (serial console doesn't seem to be supported in
EFI). If there is anything we can do to get this bug solved, please
let us know.
If this is the wrong list for this discussion, I'm sorry, I wasn't
sure which list discusses Grub2 SVN bugs/problems :)
Thanks in advance,
