I guess I was not clear enough.
The current state is:
MBR loads PBR which eventually loads the "app"
What I want is:
put grub2 on MBR (possibly also overwriting PBR) and in the grub2 menu add
an item the (chain)loads the previously mentioned "app" (there would of
course be other menu items in grub2...)
Hope this is more clear now.
