this is a sun disk partitioning scheme - not shure, if this is well supported
with grub.

AFAIR sun disklabels allows up to 8 entries - so there is no advantage in
removing the solaris standard whole disk entry.

What's on this partition? Only Grub files or also the kernel stuff?
AFAIR I used around 100-200MB years ago, but this was with SILO.

Congrats, sounds good!

Good luck,
