  103.     ║    When using a tape drive in the "3rd floppy" position, the tape     ║
  104.     ║  software should normally work fine.  However, if an actual floppy    ║
  105.     ║  drive is used in that position, additional software will be needed   ║
  106.     ║  to allow DOS to access the device.  This software, EXFDRV.SYS, is    ║
  107.     ║  available from UltraStor or your UltraStor Dealer.                   ║
