Dear all,
I'm trying to run Xen Dom0 kernel on my Xserve.
As I see I need Grub's entry like this:
menuentry "Xen 3.3 unstable -i386
{
search --set /boot/xen-3.3.gz
multiboot /boot/xen-3.3.gz
module /boot/vmlinuz-2.6.29-rc8-tip root=LABEL=/ ro console=tty0
module /boot/initrd-2.6.29-rc8-tip.img
}
I just downloaded from svn latest grub2 (revision 2032) and tried to build it.
# cd grub2
# ./configure --with-platform=efi --target=i386
# make
# ./grub-mkimage -d . -o grub.efi apple appleldr boot cat chain
configfile cpio date ext2 echo fat gpt help hexdump hfs hfsplus
iso9660 linux ls normal pc reboot reiserfs scsi search sleep xfs
multiboot module
I got error message
# grub-mkimage: error: cannot stat ./multiboot.mod
I think that make did not build multiboot.mod for efi.
Help me please.
Tell me please how to enable multiboot and module support in efi grub2?
Thank you in advance.

It isn't done yet but I'm working on it. You can be tester if you're
interested

Thank you Vladimir.
I'm really interested in it.
I'd like to be a tester.
Is it hard to commit into SVN?
Thank you in advance,
Sergey
It's very interesting for me.
I'd like to be a tester.

You don't need to. commit=upload. download=checkout. See instructions on

Ok.
I mean is hard for you to commit you code into SVN?
Anyway I hope that you inform me when it will be possible to test.
Isn't it?
Thank you.

No code will be commited before correct testing

Hi Uzer Cheg.
Any progress on the Xserve?

I did the patch for it, however it seems nobody is interested to test
it. With it I'm able to boot grub invaders on qemu-tianocore. And I have
no xserve. For convenience I resend the patch. If it works I'll split it
into components as required for review. Also have a look at
http://grub.enbug.org/TestingOnMacbook for some relevant fixes (in linux
section).

Hi,dear folks, unfortunately I have a tough working schedule last time.
It still not tested.
Hope to do it in a few weeks.

We're interested, I've got 30 Xserves that will be paper weights
pretty soon if we don't get a 64 bit linux OS on them... rendering for
3d fx in movies.
I'll try to start a http://grub.enbug.org/TestingOnXserve page shortly
to combine all the info we've gathered so far.
Thanks.

Hi,
From the wiki page you put up, you're obvious not familiar with
grub2's efi support. x86_64-efi have been in grub2 for a long time,
you just need to know how to build it, take a look at this page:
http://grub.enbug.org/TestingOnMacbook
Also, you can check out this post at ubuntu forum:
http://ubuntuforums.org/showthread.php?t=995704
D4T have successfully booted both 32-bit and 64-bit linux with Xserver
1.1 and 1.2.
BTW, please don't put anything you're not sure of to the wiki page,
it's misleading for other users.

Thanks Bean. Totally appreciate your help with this.
I'm not familiar with the x86_64 support, and these notes were created
6 months ago, but I thought they would be a good place to start...
Don't hesitate to remove anything you think is misleading. I'm going
to try to update it with better info as soon as possible.
Also, please be clear, we are not talking about Xserver. I'm trying to
run 64 Bit Linux on an Apple MacIntel Xserve.
The systems I have are 2 x 2.66 Dual-Core Intel Xeon.
Thanks!

Oh never mind, it would be nice if you can get it working, then there
is another efi platform supported by grub2.

I don't know they're different, but I guess the efi firmware is more
or less the same.
