^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
this may be its downfall.  Unforch, I do not know enough about the os9 
for the mm1 to know if it can boot from a non-contiguous bootfile.  

No coco level one, level two or nitros9 can do that as the boot module 
itself doesn't yet know enough about the disks file system to cope 
with a fragmented bootfile.  It looks in LSN0 to get the files 
location and length since it has no knowledge at that point of the 
directory structure of an os9 filesystem.

I suppose the file could be moved inward to a location that would 
allow it to be contiguous, and LSN0 then edited to reflect the new 
location.  This might work if that os9 is similar enough to level one 
or two.

I hope this does help by giving one possible cause.
