--------------------------------------------------------
               3. LIMITATIONS ADDRESSED
--------------------------------------------------------
This section lists limitations of the existing JUMBO 120/250
device drivers that have been addressed by the Beta version
device drivers.

3.1 SYTOS PLUS ACCESSES THE FLOPPY DRIVE BEFORE A TAPE
    OPERATION
    Sytos Plus no longer accesses the floppy drive before
    accessing the tape drive.

3.2 LIMITATIONS WHEN USING AN FC-10 CONTROLLER BOARD WITH
    A JUMBO TAPE DRIVE
    With the previous device drivers, conflicts sometimes
    occurred if the FC-10 controller and floppy drive 
    controller used the same DMA and Interrupt address
    settings.  If a conflict occurred, the following could
    happen:
    - The floppy drive was disabled after Sytos Plus
      accessed the tape drive, requiring a system reboot.
    - Possible OS/2 operating system crashes.

    The Beta version drivers address both of these issues.
    You should now be able to use the same DMA and Interrupt
    address settings for an FC-10 or TC-15 board and the
    floppy drive controller.
          NOTE: If you use the same settings, you should not
          access the floppy drive using another application
          while the Backup is running.

3.3 SUPPORT FOR TC-15 AND TC-15M TAPE CONTROLLER BOARDS
    Sytos Plus 1.36 for OS/2 now supports TC-15 and TC-15M
    tape controller boards for JUMBO 120/250 tape drives.
    
    3.3.1 Installing a TC-15 Controller Board
    After installing a TC-15 controller board, you must
    reboot the OS/2 operating system, and configure the tape
    drive as a Sytos Plus backup device.  Refer to the
    instructions for installing an FC-10 controller, in the
    "Read Me First" flyer.

    3.3.2 Installing a TC-15M Controller Board
    Before installing Sytos Plus, make sure that the TC-15M
    controller board is properly configured.  For configura-
    tion instructions, refer to the documentation that came
    with the TC-15M board.

    Once the TC-15M controller is properly installed and
    configured using the System Reference Diskette, the
    device settings are automatically determined when you
    configure the tape drive as a Sytos Plus backup device.

3.4 "W32: DEVICE SETTINGS DO NOT MATCH" MESSAGES
    For JUMBO 120/250 tape drives configured on the floppy
    drive controller only the following settings are valid:
          DMA 2, Interrupt 6, I/O Address 3F0.

    Using previous device drivers, some users received a
    "W32" message with these settings.  This has been
    addressed by the Beta version device drivers.

3.5 "E 128: HARDWARE ERROR" MESSAGES
    The Beta drivers reduce the occurrence of "E 128" error
    messages.  The E128 messages occurred under various
    conditions.

    If you receive an E128 error message, choose [Esc] and
    rerun your Procedure.  If you continue to receive E128
    messages, and cannot run your Procedure, contact your
    Beta representative.

3.6 UNCLEAR MESSAGE FOR DE-SPOOLED TAPE
    A more informative error code is available if a tape
    becomes de-spooled.  The following message:
         "E40: Cannot Access Backup Device"
    has been replaced with this message:
         "E82: Media is unusable".

3.7 MULTI-TASKING NOT AVAILABLE DURING A SYTOS PLUS TAPE
    PRE-FORMAT 
    Multi-tasking is now possible during all stages of a
    tape format.  

-----------------------------------------------------
             4. INSTALLING THE DEVICE DRIVERS
-----------------------------------------------------
To install the Beta drivers after Sytos Plus is installed,
use the following steps:

1. If you have not yet installed Sytos Plus, use the
   instructions that came with your Sytos Plus package to  
   install Sytos Plus and choose your backup device. 
2. Copy the following updated device driver files into the
   \SYPLUS\SYFILES directory on the drive where Sytos Plus
   is installed:
        NOTE: Rename the old driver files before copying 
        the updated driver files.

        CMM_Q80G.SYS 
        CMM_Q80G.DLL
        CMA_Q80G.SYS
        CMA_Q80G.DLL

    The default directory is C:\SYPLUS\SYFILES.
3.  Shutdown and reboot your system.
         NOTE:  Check the device driver version number on
         your screen during bootup, to verify that you have
         the correct version installed. The drivers for this
         Beta release are Rev. 1.04.
4.  Start Sytos Plus.  You may receive the following message
    that the device is not configured properly:
     "E21: Backup Device Specified Does Not Exist in the
           List of Configured Devices."
    Select [Esc].
5.  Go to the "Utilities: Backup Device setup..." window.
    Highlight and delete the existing driver.
6.  Select "Add new device."  The "Add New Backup Device"
    window opens.
7.  Select the device driver and choose [OK].  The "Setup
    Backup Device" window opens.
8.  Edit the device settings if necessary.  For JUMBO
    120/250 tape drives that use the floppy drive
    controller, only these settings are valid:
        DMA 2, Interrupt 6, I/O Address 3F0.
9.  Select [OK].  If you receive the following message, the
    settings are not valid:
       "W32:  Device Settings Do Not Match"
    To correct the problem, check that the settings are not
    being used by another device in your system.
         NOTE:  If your JUMBO 120/250 tape drive is
         configured to use the floppy drive controller,
         and you receive this message, contact your Beta
         representative.
10. Choose [OK] to save the edits.
