                INT 13,D - Alternate Disk Reset  (XT & newer)

       AH = 0D
       DL = fixed drive number  (80h=drive 0, 81h=drive 1)

       on return:
       AH = status  (see INT 13,STATUS)
       CF = 0 if successful
          = 1 if error

       - many good programming references indicate this function is only
         available on the AT, PS/2 and later systems, but all hard disk
         systems since the XT have this function available
       - used to force drive recalibration similar to INT 13,0
       - drive heads are positioned at track zero
