Any progress on this?
Not really, sorry. Do you have any suggestion how such option should be
named?
Sorry for delay - this got lost in the noise.
Well something like --no-id-or-nvram ??
Not really bothered about the name! :)
I was about to suggest a patch when I realized that this probably is
currently useless on EFI. I.e. to actually chainload grub on EFI it
must reside on a partition accessible by firmware which practically
means it should be ESP.
Unless someone submits patch to make grub2 EFI core.img multiboot2
compliant with tag to skip ExitBootServices.
Does chainloading from /boot/grub actually work for you on EFI? Could
you explain your configuration in more details?
Sorry for the long delay I missed your reply. We could really do with a
patch for this as Mageia 6 is in freeze. ;)
Yes it works fine from a separate small grub2 partition.
The grub2 install to the small dedicated grub2 partition is installed by
my script here: https://wiki.mageia.org/en/User_talk:Barjac
This is my current grub.cfg created by the script:
set default="0"
set timeout=10
if loadfont unicode ; then
set gfxmode=1024x768x32
insmod all_video
insmod gfxterm
set locale_dir=/locale
set lang=en_GB
insmod gettext
fi
terminal_output gfxterm
insmod part_gpt
insmod ext2
# Theme
insmod gfxmenu
loadfont /grub2/themes/maggy/MageiaLogo-Bold-16.pf2
loadfont /grub2/themes/maggy/MageiaLogo-Bold-20.pf2
loadfont /grub2/themes/maggy/MageiaLogo-Bold-28.pf2
loadfont /grub2/themes/maggy/MageiaLogo-Regular-20.pf2
insmod png
