             INT 13,9 - Initialize Fixed Disk Table (XT & newer)

       AH = 09
       DL = fixed disk number  (80h=drive 0, 81h=drive 1)


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


       - sets specified fixed disk table to the default values from ROM
       - 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
       - INT 41h vector is pointer to table for drive 0
       - INT 46h vector is pointer to table for drive 1
