Thanks again for all the notes, without them I certainly would have spend a
couple of more hours compiling this tougher, ..! ;-)
It looks like I ended up needing -eltorito-alt-boot -no-emul-boot in between
the x86-mbr and the above hybrid stuff, does that make sense?
e.g. something like:
-b boot/grub/i386-pc/eltorito.img -no-emul-boot
-boot-load-size 4 -boot-info-table --grub2-boot-info --protective-msdos-label
--grub2-mbr $build_root/usr/lib*/grub/i386-pc/boot_hybrid.img
-eltorito-alt-boot -no-emul-boot -partition_offset 16
-append_partition 2 0xef $isofsdir/efi.img
-e --interval:appended_partition_2:all::
-iso_mbr_part_type 0x83
Or is should that be reversed, or am I missing something else?
With this it builds an ISO and it i386-pc boots, not yet sure about EFI, at
least Qemu/OVMF does not like to boot from that ISO, yet :-/
Thanks again, and have a great Sunday,
René
