[Coco] double-sided floppy setup in OS-9

[Chad H]

I have OS-9 Level 1 on a CoCo 2 so DMODE won't work for me?  I thought about
jumping on NitrOS-9.  Would that be easier to set up?

The ability to use dmode to make double sided drives work depends on which 
version of OS9 is being used. The first versions of OS9 level 1 did not 
support double sided drives at all, and indeed a new driver was written for 
that version.

IIRC, later versions, and OS9 Level 2 did support changing drive descriptors

that way.
