[Coco] some progress...

Hi,

Wrong. You just need the proper disk driver, I assume that NitrOS-9 has this 
already.

Then you need the proper program. I used sdisk so someone else will have to 
supply the name.

Again wrong, others can supply the details. I am talking about a real CoCo 3 
system so virtual disks have to be transferred to a real floppy.

I have one 5 - 1/4" drive and one 3.5" drive in my system and with a toggle 
switch can change which drive is /D0 and which drive is /D1.

With two identical OS-9 boot disks, one a  5 - 1/4" disk and one 3.5" disk, 
I can even swap drives when OS-9 is running.

I have many pairs of disks identical except for the size.

My floppy drives have the jumpers for drive selection, that might be hard 
with a 3.5" drive that does not.
