OK, thank you.

I'll try to integrate some of these patches (the trivial ones) into the openbios main repository.

(but I really don't understand why commit 4722c8a01d186a08183de49759dc8b7b74cf41c9 is needed, if someone can explain...).

With some media I tried (I think it was the Mac OS X 10.3 install
disc), OpenBIOS didn't see that there was an HFS+ partition because
the disc had an Apple Partition Map instead of what OpenBIOS expected
(a single partition formatted HFS+, and no extra Apple Partition Map
data). The commit in question (4722c8a01...) fixes this, allowing it
to read the APM to find the bootable HFS+ partition and reading from
there.

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).
