yaboot now working on g4.

[Brendan J Simon <Brendan.Simon@ctam.com.au>]

I changed the ofboot.b file so as to include the partition number.
Apparently this is a bug in yaboot_0.5 and will be fixed in the next
release.

I changed the file from
    boot hd:,\\yaboot
to
    boot hd:2,yaboot

Thanks for everyones help.
Brendan Simon.
