OK, I understand better now. Thank you for the explanation.

But I think it should be managed from modules/mac-parts.c, not from
fs/hfsplus. I have a patch doing this kind of stuff to implement the
command "boot hd:%BOOT" to boot using the bootsector of first bootable
partition (for QUIK).

I think we should boot using "boot cd:,System\Library\CoreServices
\BootX" and lets mac-parts select the first HFSPlus partition
(pmPartType is "Apple_HFS"). But there is no specification describing
that...

I try to do that (and I send you a patch).

Regards,
Laurent
