      The 12F has a BIOS setup menu that is accessed using DEBUG at the    
      controller's address, with an offset of 5.  Thus, if you set the     
      address to C800, you'd type DEBUG, then -g=c800:5 to get to the      
      setup menu.  The latest BIOS as of this writing is #9.00, and this   
      guide reflects that.

          NOTE:  As of the revision 9 BIOS, the rev.7 manual that I have   
                 is out of date, so UNIX setup info is up to you. (sorry)  
                                                                           
    Ŀ Additional Info Ķ
                                                                           
        When using a tape drive in the "3rd floppy" position, the tape     
      software should normally work fine.  However, if an actual floppy    
      drive is used in that position, additional software will be needed   
      to allow DOS to access the device.  This software, EXFDRV.SYS, is    
      available from UltraStor or your UltraStor Dealer.                   
        Each drive should be Prep'd with the utility accessed through the  
      DOS Debug command.  Normally, the User will initiate a Low Level     
      Format with the AUTOFORMAT field set to BRIEF.  Choosing EXTENDED    
      adds considerable time to the format, which is fully automatic.
