Hi, It's already implemented in my BURG branch, check this thread: http://lists.gnu.org/archive/html/grub-devel/2009-10/msg00215.html > And, as was mentioned, > there's EFI support, which is also essential.

If you can find related document on how to use the firmware interface, I can integrate it into grub. -- Bean My repository: https://launchpad.net/burg Document: https://help.ubuntu.com/community/Burg _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
