MBR and RDB partitions

Hi ofppc users!

Since a few days I'm successfully running a new disksubr.c for ofppc
which supports MBR and RDB partitions at the same time. So you can e.g.
easily create your NetBSD partitions in parallel to MorphOS on a Pegasos2.

Before I can commit, there are two points on my todo list:

1. For the moment my MBR support is the same as in macppc, which works fine
with USB keys and the like, but I'm unsure if it works when creating a
NetBSD label inside a MBR partition.

Does anybody need that? Or is it common to install a raw NetBSD label
without MBR parititions for ofppc?

2. I know that RDB only makes sense for Pegasos2 (Pegasos1 anyone?) and
maybe Efika 5k2, when we support it some day. So I should probably use
a config file option for disabling RDB-support when it is not needed, to
save space?

Re: MBR and RDB partitions

Hi,

I comitted a new disksubr.c for ofppc, which supports raw NetBSD labels,
disklabels in an MBR parition and disklabels constructed from RDB
partitions, at the same time. It works similar to macppc (just with RDB for
APM).

RDB can be disabled with a config file option, for all those platforms which
don't need it, to save space.

I'm happily running MorphOS, AmigaOS4 and NetBSD on the same disk now. :)

Please tell me when there are any problems left.
