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 Uzer Cheg.
Any progress on the Xserve?

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.
