   Mount options for hpfs
...
       case={lower|asis}
              Convert all files names to lower case, or leave them.  (Default: case=lower.)

       map={n[ormal]|o[ff]|a[corn]}
              For non-Rock Ridge volumes, normal name translation maps upper to lower case ASCII, drops a trailing `;1', and converts `;' to `.'.  With map=off no name translation is done.  See norock.  (Default: map=normal.)  map=acorn is like map=normal but also apply Acorn extensions if present.
