Hi Peter / phcoder / all other grub gurus,
I've joined the grub-devel mail list while attempting to get MacIntel
Xserves to boot linux. I work with a 3d Movie Effects company that has
25 MacIntel Xserves that are becoming close to as useful as
paperweights because they can't run Maya at 64bit for rendering. (and
we can't repurpose them as linux servers).
Any chance we can help test this patch in an xserve environment, and/
or do you have any ideas that would help us?
Here's the most discouraging info I've received in my research to date:
The Xserve does not have BIOS compatibility, and so you'll need to
boot through EFI. The Apple EFI implementation will not boot directly
off ISO9660 media, so you'll need to find a way to get to the EFI
console. You'll need a kernel configured with EFI support. There's no
especially sensible way to get a working framebuffer on this hardware,
so you'll need to work out what arguments need to be passed to your
distribution's installer in order to get it to run over the serial
port. elilo or grub-efi should be able to boot the kernel and initramfs.
I've been catologing my research at:

Thanks!

Tested the patch applied to rev 1996 for grub.efi 64 bit and 32 bit,

All good.
64bit Macs have other ongoing EFI problems with linux kernel
initializtion and keyboard.
