That does match what is returned. Grub later assumes H=255 if it falls back to CHS as far as I can tell. H=255 S=63 would be really bad for alignment on SSDs and such (not that H=16 is a whole lot better, but it is better). -- Len Sorensen _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
