There's a tickle at the back of my brain that says that one of the versions
of DOS allowed the use of DRIVPARM, but only through a very shifty
"workaround".  IIRC (and I'm not sure that I do), you had to prefix the
word "DRIVPARM" with a hex FF byte. 

Can someone with a better memory confirm this one?
