Typical DMODE output:
<screen>
OS9: dmode /dd  {enter}

 drv=$00 stp=$00 typ=$80 dns=$01 cyl=$0334 sid=$06
 vfy=$00 sct=$0021 tos=$0021 ilv=$00 sas=$20
</screen>

Now, let's say we want to change the number of cylinders
this descripter shows. The following command lines would
all be valid and accepted by the new DMODE:

<screen>
OS9:  dmode /dd CYL=276
-or-  dmode /dd Cyl=$276
-or-  dmode /dd cYL=276
</screen>

Lastly, you may now specify either "TOS" or "T0S" to setup
the number of sectors per track in track zero. Example:

<screen>
OS9:  dmode /dd tos=21
-or-  dmode /dd t0s=21
</screen>
