That is exactly what should happen. Toolshed os9 requires the -e parameter to 
get a full disk. Getting a 4MB disk with 'format /x1' is also exactly what 
should happen. I told you that you must specify what sized disk you wanted but 
could not tell you how, because you originally had not stated the size of /d0.

While running NitrOS-9 via Drivewire with a 0-byte disk mounted in /x1 and 
requiring a 40-track single sided disk, you have two options. You can use dmode 
to alter the specs of /x1 or you can add parameters to the format command.

format /x1 1 '40'
Gives you a single sided 40-track disk but leaves the default values of /x1 
untouched.

dmode /x1 cyl=28 sid=1 typ=20
Changes /x1 to mimic a single sided, 40-track floppy and you will not require 
parameters with the format command. This change will revert on the next Boot 
unless you cobbler the boot disk.
