You can just as easy tell it
os9 format -e -t35 -ss -dd -q 
for a 35 track SS image.

This may need investigating, it needs to do so if -t80 and its a 5.25" 
disk.  ISTR there is/was an option to do so.  However my machine is down 
ATM, so I can't check other than reading the format.asm code.  As I am not 
able to do that well till my machine is running again, I'll pass on making 
a SWAG.

I would much rather we fix the descriptor makers to do that correctly, AND 
then let format get the disks format from the descriptor, which it can do 
just fine.
