Here it is, exactly as I got it from the net.  I have tried it and it
works.  This is to fix a bug which prevents DRIVPARM from working
properly in in MS-DOS 3.3.  I am told that Microsoft
has released 3.30A which fixes the bug, but this is a nice workaround.

What I would *really* like to know is how Bob (or whoever did it) figured
this out.

I did post this before, but I fear it got lost....

There is a simple way of making DRIVPARM work, at least on PC-DOS 3.3 (I have
tried it and it works). It is *extremely* baroque, but who cares?

Place three control-A characters (yes, the ASCII value 1) into the line
after the DRIVPARM= bit, before the parameters. If we represent CONTROL-A
as ^A, the line might look like this:

     DRIVPARM=^A^A^A/D:n /F:n   ... etc

I don't know why it works, but it sure does!
