DRIVPARM is undocumented only for PC-DOS.  The line you need in
config.sys is this:

           DRIVPARM=^A/D:1 /F:2

Notes: 1) following the = sign, that is a single ^A, Control-A.  No
          space, or you'll get an "unrecognized command" error.
       2) above line assumes B: drive is the 3 1/2"; change /D:1 to /D:0
          for A: drive
