OS-9 is coded to boot from drive 0.  The DOS command does not care which 
drive it starts from, however, OS-9's boot routine automaticaly looks on 
drive 0 to continue loading.

Solution;
BACKUP to a 3.5" disk formated as a single sided 35 track your OS-9 boot 
disk.  You can then boot from your 3.5" drive and build your custom boot 
disk from there.
