I'd be happy to document errors and such if someone can recommend what
the best path of target is.
Maya rendering doesn't actually touch the video cards (some of our
linux systems don't even have video cards), and general usage servers
don't care much so drivers for the systems aren't a huge concern as
long as the systems don't crash.
i'll try to setup a dev system this weekend and get some feedback
posted. are there any critical steps and/or locations for submitting
data for this project that i should know? or just post on a web wiki
and send an email?
thanks!!!

Hi,
True we don't have any grub.efi Apple intel Xserve hardware tests so
far, at the apple intel ubuntu forum, but the grub-efi test packages
there could be used to test.
Seems you will need to get some current grub.efi test result to
point to problems specific to the Xserve, sufficient to attract help
at developer level.
There are also some graphics limitations (use of framebuffer driver)
after EFI linux booting for other intel macs, might be important for
your application.

Thanks for your interest in helping Peter. At first look, the ubuntu
forum looks like we're seeing xserver info, but no one using
MacIntel Xserve hardware to test grub. If you know anyone who could
help us push thru what is causing the Xserve to not work like the
MacIntel Mac Pro Desktops, I'M LOOKING FOR THAT PERSON...
Cheers.

I am just a grub.efi user/tester/enthusiast.
I don't know the Xserve but some previous reports in this list of
people getting grub.efi to boot on Xserve, and if so it will boot
hd/usb linux on other Apple intel Macs with varying results .
There are some grub.efi 64/32 bit test packages on ubuntuforums
that you might try (include the patch) . Xserve results would be
interesting.

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

with Macosx 10.4 10.5, ubuntu810.
All good.
64bit Macs have other ongoing EFI problems with linux kernel
initializtion and keyboard.
