A PS to my previous post.  In the nos96309l2_dw3.dsk image, the byte at 
offset $10 is a $03, which I believe tells nitros9 its an 80 track disk.  
Edit that to a $02.  Then at offset $41, the $01 is an $03 on a 10 year old 
40 track DS boot disk.

You want to generate a disk that dtype says is:

{t2|07}/DD:dtype /d0
As formatted, this volumes name is OldfaithfullBoot960925
drv=0 stp=3, 5.25 inch diskette, color computer format.
It is a standard OS-9 format, floppy diskette,
dns=01 with single track density or 48 tpi.
cyl=0028  sid=02  vfy=ON  sct=0012  t0s=0012  ilv=03  sas=08

Yeah, ignore the name, that disk is coming up on its 15th birthday.  But a 
lot of the hardware it needs to boot has been changed or nitros9 has no 
support for because the stuff needed has been deleted, like the drivers for 
a WP-RS that I ran a 2nd 13" amber screen monitor with.  Also the serial 
mouse was excised when cc3io was broken up, so I have yet to make multivue 
work even with my new joydrive_6551.sb driver.

I miss that extra monitor, it was handier than sliced bread or bottled 
beer.

Cheers, gene
