I still have a working Amiga here, and MorphOS, which come with the 
Pegasos, is AmigaOS compatible.
I even still develop an application for it which should be finished 
soon! :-)

Sounds good, I think.

I have also another remark about the Amiga RDB; since the block can be 
in the first 16 blocks of a device, it could easily be added alongside 
an existing partitioning information.
I.e. you could have an Intel style partitioning block at the beginning, 
and the Amiga RDB on the same disk, describing the same layout. At 
least, I am pretty sure that no one used it that way yet, it would 
easily be possible to be able to switch your hard drives from one 
system to the other while still being able to access (nearly) all 
partitions. So we might just ignore it :-)

Adios...
