As Rob Gault pointed out, (nitr)OS-9 doesn't actually know about
partitions, so we fake it out.  The problem with this is that each
hard drive driver suite does it differently.  

With the Glenside drivers, we create device descriptors (/h0, /h1,
/etc) that point to the same drive, but in seperate "partitions".
Again, as Gault describes, the descriptors have an offset that gets
added to the given sector number before the drive is actually read.

Unfortunately I haven't used Cloud-9's software, so I can't really
give you specifics(*), but it probably works about the same way -- make
your descriptors, put them in a new boot disk, reboot and they should
be active. 

(*)This may not be a bad thing for you -- the last guy I tried to help
set up an OS-9 hard drive got so disgusted that he sold all his coco
stuff on ebay. :-(
