[comp.os.msdos.misc] DRIVEPARM switches

bill@polygen.uucp (Bill Poitras) (12/11/90)

A while back, someone posted an undocumented switches to the DRIVPARM
config.sys line to allow a B: drive be recognized as a 720K drive on an
XT.  I used it on my XT to allow the 3.5" drive on it allow formatting
its disks to 720K.  Without this line, you couldn't do it without using
driver.sys and causing the creation of an other driver letter.  Post or
e-mail I don't care.  Thanks in advance.

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
