[Coco] Newest Nitros9 and B&B

The boot module isn't the same thing as a driver module.  It is a  module that is involved in booting the system off a disk of some sort,  getting things set up, and then passing control off to the  kernel.  Since it is operating before the system is completely  loaded, it doesn't have the benefit of being able to use the regular  disk device driver, so it needs to know how to access the disk  itself.  The stock Boot module that came with the original OS-9  sysetm master disks only knew how to boot OS-9 from a floppy, using  Tandy's disk controller, or a compatible one.  The boot.burke boot  module must know how to load the rest of (Nitr)OS-9 from the B&B  hard drive interface.  But once the OS gets loaded, boot isn't  called again unless you hit reset.  One of the modules it loads  from the HD must be a proper driver for the B&B interface.

device descriptor?  Like h0, h1?  I do have them, but since the Os-9
operating system has been optimized for the 6309 I assumed the software for
the B&B needed to be as well.  I do own the original disks for the
controller.  When the superboard becomes available I won't have to worry
about any of this stuff.  Hallelujah!!  I'm frothing at the bit for that,
but for now I have to work with what I have.  It will be worth the wait I'm
sure!  The good thing out of all this is that I learned how to get a dsk
image onto a real coco disk and learning is what it's all about for me.

Thanks to everybody for all the help.

This  is true, assuming that 10-20 year old drivers assembled for the 6809
version of OS-9 still work on current versions of NitrOS-9.  I'm  not saying
they won't, because I haven't done enough experimenting with  it yet.  But
it may be a consideration.  
  Is there any clearly defined way one could contribute to the documentation
