Not enough coffee :)

Gene, you are right that you can't get there from here. Boot from /d0 and the 
wrong boot module will be in memory. That can only be changed with a utility 
like chboot by Alan DeKok, which must be somewhere on the Web. I have a copy 
(written for OS-9 not NitrOS-9) which can change in memory REL, BOOT, OS9P1, or 
a combination. I don't believe this has been rewritten for NitrOS-9.

The only other hope for a pure stock Coco system is to start a RAM disk under 
Disk Basic, populate it with NitrOS-9, and then boot from the RAM disk.
Now if Ed is willing to buy a hard drive for the Coco or Roger's DrivePak, then 
floppies will not be required. Both the hard drive and DrivePak are silent and 
fast enough to satisfy a RAM disk user.
