There is no equivalent to a PC partition under OS-9. You can do it, but 
it requires a modified driver that automatically adds an offset to all 
LSN when doing disk I/O. In effect, it is exactly what HDB-DOS or 
RGB-DOS does when accessing the Disk Basic portion of the hard drive.

So, check your /H0 descriptor for the size of the hard drive in sectors. 
That's the offset a special hdisk.dr will need to add for each I/O 
intended for another partition. Possibly Cloud-9 has built this 
provision into their driver with a new variable in the descriptor 
holding the offset.
