Thank you - though I am ignorant about whether at some point in the
future the gap would be a "requirement" and whether the core.img may
get large and cause an issue - certainly I use another distro on a
server where grub2 is the bootloader with BIOS and standard
partitioning and it also has no problems at all  though in that case
the core.img file is in a directory in /boot - but having seen dire
warnings on various web pages I wanted someone who knew to confirm
that grub2 in the old style BIOS and disk partitioning would continue
to work into the future or not!
