I just reviewed this thread and it seems pretty straight forward. You 
can't create a boot disk that will boot from the hard drive until you 
format the hard drive for OS-9 use, create a CMDS directory, and add 
other needed files.

If you want, you can create a boot disk that boots as a floppy but 
contains the hard disk drive and descriptor. That will permit you to 
create the OS-9 partition on the hard drive. However, that is not 
necessary. You can also merge the driver for the hard disk and the 
descriptor h0 into a single file, run attr e pe on the merged file, load 
the file and iniz h0. That will also give you access to the hard drive.

One thing that may be causing problems is a conflict in your os9boot 
file. Scsisys and h0 obviously are a driver descriptor for hard drive 
use, but what is tcc512. Is that for hard drive use or floppies?
