                   1.0  NEW FEATURES
-----------------------------------------------------------

1.1 SUPPORT FOR MS-DOS 6.0
    This version of Sytos Plus supports MS-DOS version 6.0.

1.2 IBM PS/2 REWRITABLE OPTICAL DRIVE SUPPORT     
    The IBM PS/2 Rewritable Optical Drive can be configured
    as a backup device for Sytos Plus in one of two ways: 
    - as a Removable Logical Device, or 
    - as a Fixed Logical Device. 
    There are different Sytos Plus device drivers for the 
    two configurations:
    - Removable Logical Device Driver: IBM Optical-Entire     
    - Fixed Logical Device Driver:     IBM Optical-Partial

1.2.1 Removable Logical Device
      To configure an Optical Drive as a removable logical
      device, refer to the Section, "Removable Logical
      Device Support: IBM PS/2 3.5" Rewritable Optical
      Drive" in this README file.

      When an Optical Drive is configured as a Removable
      Logical Device, Sytos Plus provides the following 
      support: 
      - Multiple device: More than one Optical Drive can be
        used for a single Procedure.     
      - Multiple media: When end of media is reached, Sytos
        Plus will prompt for new media.
           NOTE: An Optical Drive configured as a removable
           drive does not require formatted media.  However,
           backups to unformatted media will take longer
           than backups to formatted media.

1.2.2 Fixed Logical Device
      To configure an Optical Drive as a Fixed Logical
      Device, refer to the Section, "Fixed Logical Device
      (Fixed Disk) Support" in this README file. When using
      the Fixed Logical Device Driver, Sytos Plus provides
      the following support:     

      - Multiple Fixed Logical Devices: The driver can be
        used with devices such as optical drives or fixed
        disks.  (Floppy devices are not supported.)
      - Fixed media: You must use formatted media and must
        allocate enough space on the media for the files
        you will back up. You do not have the option of
        inserting new media.
           NOTE: You must use formatted media. You may then
           allocate a portion of the media, or all of the
           free space for the files you will back up.

1.3 REMOVABLE LOGICAL DEVICE SUPPORT: IBM PS/2 3.5"
    REWRITABLE OPTICAL DRIVE     
    This release of Sytos Plus lets you back up to and
    restore from the IBM PS/2 3.5" Rewritable Optical Drive.
    Before you can configure the drive in Sytos Plus as a
    backup device, it must be accessible from your operating
    system. (To verify that you can change to the drive,
    type the assigned drive letter at the system prompt.)

    One additional device driver, IBMRWOPT.SYS, must already
    be installed to access the device. If you have not
    installed this device driver, refer to the "IBM Personal
    System/2 Rewritable Optical Drive Setup Instructions" 
    that came with the device.

    To configure the Rewritable Optical Drive as a Sytos
    Plus backup device, ensure that the device is powered on
    and has media inserted.  Media does not have to be
    formatted; however, backups to unformatted media will
    take longer than backups to formatted media.     

    1. Select "Utilities" from the Sytos Plus Startup screen
       or from the "Edit Procedure" screen.
    2. From "Utilities" select "Backup Device Setup."
    3. Select "Add New Device."
    4. Select the Removable Logical Device Driver "IBM
       Optical-Entire" from the list, and select [OK].     
    5. Select the Drive letters for one or more Rewritable
       Optical Drives from the list, and select [OK].

    Multiple Rewritable Optical Drives can be cascaded; that
    is, several drives can be used for a single Procedure.
    This is useful when performing Unattended Backups for a
    large number of files. If your backup set does not fit
    on one media, Sytos Plus continues the Procedure on the
    next drive.  

    Sytos Plus prompts for additional media when the end of
    media is reached in a single drive, or in the last drive
    when multiple drives are cascaded.

1.4 FIXED LOGICAL DEVICE (FIXED DISK) SUPPORT     
    This release of Sytos Plus can back up to and restore
    from logical devices including local fixed disks and the
    IBM PS/2 3.5" Rewritable Optical Drive.  (Floppy drives
    are not supported.)
           NOTE:  The Fixed Disk driver is not supported
           with the DoubleSpace feature of MS-DOS 6.0.
  
    Before you can configure a drive in Sytos Plus as a
    backup device, it must be accessible from your operating
    system. (To verify that you can change to the drive, 
    type the assigned letter at the system prompt.)

    One additional device driver, IBMRWOPT.SYS, must already
    be installed to access the device. If you have not
    installed this device driver, refer to the "IBM Personal
    System/2 Rewritable Optical Drive Setup Instructions"
    that came with the device.

    To use a Rewritable Optical Drive as a fixed logical
    backup device, it must have formatted media installed.
    Several drives can be cascaded; that is, space on
    several drives can be used for a single Procedure. You
    must ensure that sufficient space is allocated on the
    drive, or across all drives if in a cascaded configura-
    tion, for the amount of data to be backed up. A Backup
    Procedure will not complete without sufficient space.
           NOTE: You must have Read and Write access rights
           to any drive that you wish to configure as a
           Sytos Plus logical device.

    To add the Fixed Logical Device: 
    1. Select "Utilities" from the Sytos Plus Startup screen
       or from the "Edit Procedure" screen.
    2. From "Utilities" select "Backup Device Setup."
    3. Select "Add New Device."
    4. Select the Fixed Logical Device Driver "IBM Optical
       -Partial" from the list and select [OK]. 
    5. Select a drive from the "Setup Backup Device" window. 
    6. Edit the selected drive to specify a pathname and to
       allocate space, then select [OK]. 
           NOTE: Make a note of the exact configuration for
           each device, including drive(s), pathnames, and
           allocated space. You will need this information
           if you have to reconfigure your backup device.
    7. If you want to add additional drives, select and edit
       each drive as described in steps 5 and 6.  
    
------------------------------------------------------------
                      2.0 INSTALLATION
------------------------------------------------------------

2.1 INSTALLING ON SYSTEMS WITH BACKUP DEVICES THAT USE DPT
    (DISTRIBUTED PROCESSING TECHNOLOGY)(R) SCSI ADAPTERS 
    If your backup device requires a DPT SCSI adapter,
    check that the SCSI driver is on your system before you
    install Sytos Plus.

    If your CONFIG.SYS file contains a DEVICE= line for
    DPTDDL.SYS, the SCSI driver has already been installed
    and you can install Sytos Plus.    For example, the
    CONFIG.SYS entry for DPTDDL.SYS is:
       DEVICE=[drive:]\[pathname]\DPTDDL.SYS

    where [drive:]\[pathname] is the directory where
    DPTDDL.SYS exists.

    If a line for the SCSI driver does not exist in
    CONFIG.SYS, you must install the driver.  Refer to the
    installation instructions that were included with
    the SCSI adapter.  Complete the following steps to
    install the device driver, in order to access your
    backup device. 
    1. Install the DPT SCSI adapter driver.
    2. Reboot your system so that the changes to CONFIG.SYS
       can take effect.
    3. Install Sytos Plus.

    If you do not choose a SCSI device as your default
    backup device while installing Sytos Plus, you must
    complete the next set of steps when you add the SCSI
    device to your system. 

    1. Install the DPT SCSI adapter driver.
    2. Reboot your system so that the changes to CONFIG.SYS
       can take effect. 
    3. Start Sytos Plus and select "Add new device" from
       "Utilities: Backup Device Setup" to install your SCSI
       device.
         NOTE:  If the device you want to add does not
         appear on the backup device list but is on the
         Sytos Plus Installation diskette or a Sytos Plus
         Driver Diskette, refer to the section "Copying
         Device Drivers from a Diskette," in Chapter 11 of
         the Sytos Plus User's Guide.

2.2 INSTALLING ON SYSTEMS WITH BACKUP DEVICES THAT USE
    ADAPTEC(R) SCSI HOST ADAPTERS 
    If your backup device requires an Adaptec SCSI host
    adapter, check that the Adaptec SCSI device driver is on
    your system before you install Sytos Plus.

    If your CONFIG.SYS file contains a DEVICE= line for
    ASPI4DOS.SYS or ASPI2DOS.SYS, the SCSI driver has
    already been installed and you can install Sytos Plus.
    For example, the CONFIG.SYS entry for ASPI4DOS.SYS is:
       DEVICE=[drive:]\[pathname]\ASPI4DOS.SYS

    where [drive:]\[pathname] is the directory where
    ASPI4DOS.SYS exists.

    If a line for the SCSI driver does not exist in
    CONFIG.SYS, you must obtain a software package from
    Adaptec.  Use the following table to determine which
    SCSI device driver (Adaptec ASPI Manager) you need, and
    in which Software Package it is included.
           NOTE: The ASPI2DOS.SYS or ASPI4DOS.SYS driver
           should be loaded in CONFIG.SYS before any memory
           management or caching device drivers.

    SCSI HOST      REQUIRED       SOFTWARE
    ADAPTER        DRIVER         PACKAGE
    AHA-151x       ASPI2DOS.SYS   ASW-1210   
    AHA-152x       ASPI2DOS.SYS   ASW-1210   
    AHA-164x       ASPI4DOS.SYS   ASW-1410   
    AHA-154x       ASPI4DOS.SYS   ASW-1410   
    AHA-174x*      ASPI4DOS.SYS   ASW-1410   
    (*AHA-1740 in standard mode)
    
    Complete the following steps to install the ASPI
    Manager, in order to access your backup device. 
    1. Install the ASPI Manager using instructions in the
       software package from Adaptec. 
    2. Reboot your system so that the changes to CONFIG.SYS
       can take effect.
    3. Install Sytos Plus.

    If you don't choose a SCSI device as your default backup
    device while installing Sytos Plus, you must complete 
    the next set of steps when you add the SCSI device to
    your system. 

    1. Install the ASPI Manager using instructions in the
       software package from Adaptec. 
    2. Reboot your system so that the changes to CONFIG.SYS
       can take effect. 
    3. Start Sytos Plus and select "Add new device" from
       "Utilities: Backup Device Setup" to install your SCSI
       device.
           NOTE:  If the device you want to add does not
           appear on the backup device list but is on the
           Sytos Plus Installation diskette or a Sytos Plus
           Driver Diskette, refer to the section "Copying
           Device Drivers from a Diskette," in Chapter 11 of
           the Sytos Plus User's Guide.

2.3 INSTALLING ON SYSTEMS WITH BACKUP DEVICES THAT USE
    FUTURE(R) DOMAIN SCSI ADAPTERS
    If your backup device uses a Future Domain SCSI adapter,
    check that the device driver for the adapter is on your
    system before you install Sytos Plus.  Follow the 
    instructions in the appropriate section below, depending
    on whether you are using a 16-bit or an 8-bit Future
    Domain SCSI adapter.

2.3.1 Installing Sytos Plus on systems with devices that
      use a 16-bit SCSI Adapter
           NOTE: If your CONFIG.SYS file contains a line for
           DCAM1800.EXE, the device driver for the 16-bit
           SCSI adapter has already been installed and you
           can install Sytos Plus.  The following is an
           example CONFIG.SYS entry for a DCAM1800.EXE
           driver installed in the root directory:
             DEVICE=C:\DCAM1800.EXE
     a. Install the SCSI adapter driver if it has not been
        installed and add a DEVICE= line to CONFIG.SYS. 
        Refer to the documentation that was included with
        the Future Domain SCSI adapter.
     b. Reboot your system so that the changes to CONFIG.SYS
        can take effect.
     c. Install Sytos Plus.

2.3.2 Installing Sytos Plus on systems with devices that use
      an 8-bit SCSI Adapter
           NOTE: If your CONFIG.SYS file contains a line for
           DCAM950.EXE, the device driver for the SCSI
           adapter has already been installed and you can
           install Sytos Plus.  The following is an example
           CONFIG.SYS entry for a DCAM950.EXE driver
           installed in the root directory:
             DEVICE=C:\DCAM950.EXE /CA00 3
           The DEVICE= line must include the memory address
           and interrupt line number (IRQ) for each 8-bit
           SCSI adapter installed.
     a. Install the SCSI adapter driver if it has not been
        installed and add a DEVICE= line to CONFIG.SYS. 
        Refer to the documentation that was included with
        the Future Domain SCSI adapter.
     b. Check your CONFIG.SYS file to ensure that the
        DEVICE= line for DCAM950.EXE includes the memory
        address and interrupt line number (IRQ) for each
        8-bit adapter.  If you installed more than one
        adapter, the memory address and IRQ can be listed on
        one line as shown below:
          DEVICE=C:\DCAM950.EXE /xxxx i /xxxx i
       where "/xxxx" is the memory address and "i" is the
       IRQ number.  Possible memory addresses include /CA00,
       /C800, /CE00, and /DE00.  Possible IRQ numbers
       include 3, 4, 5, 10, 11, 12, 14, and 15.
     c. Reboot your system so that the changes to CONFIG.SYS
        can take effect.
     d. Install Sytos Plus.

2.4 SPECIAL INSTRUCTIONS FOR MODIFYING CONFIG.SYS WHEN
    INSTALLING SYTOS PLUS UNDER DOS 6.0
    Under DOS 6.0, you can create multiple configurations
    using different "blocks" within one CONFIG.SYS file. 
    You can then select one configuration from a boot-up
    menu.

    You can let Sytos Plus automatically modify CONFIG.SYS
    during installation. However, Sytos Plus adds commands
    to the beginning of CONFIG.SYS, and it is possible for
    the commands to be added to the wrong configuration
    block. You may need to edit CONFIG.SYS later and move
    the modifications to the correct configuration block.

    Refer to your DOS 6.0 documentation for more
    information.

-----------------------------------------------------------
                       3.0 MISCELLANEOUS
-----------------------------------------------------------

3.1 IBM 8505 (5.0GB 8mm) TAPE DRIVE SUPPORT
    This version of Sytos Plus provides support for the IBM
    8505 drive, a 5.0GB 8mm tape drive with Quick File
    Access (QFA) support.  When using a 5.0GB drive as a
    Sytos Plus backup device, note that:

    - A 5.0GB tape drive can read tapes created on a 
      2.3GB 8mm tape drive.

    - A 2.3GB tape drive cannot read tapes created on a
      5.0GB 8mm tape drive.
           NOTE: A tape created on a 2.3GB drive can be
           Appended to on a 5.0GB drive.  The tape can then
           be read in the 2.3GB drive.

3.2  CREATING A BACKUP TAPE ON AN NCR 5GB 8mm TAPE DRIVE
     THAT IS READABLE ON A 2GB TAPE DRIVE
     In order to create a backup tape on an NCR 5GB tape
     drive that will be readable on a 2GB tape drive, you
     must use the 2GB device driver.  Set up the 2GB device
     driver,    "NCR 6091 2GB 8mm," using setup instructions
     in the User's Guide.

     If you do not use the 2GB driver, the backup tape will
     not be readable on a 2GB tape drive.

     Under normal operation, backing up to 5GB tapes on a
     5GB tape drive, use the device driver for the 5GB
     drive, "NCR 6091 5GB 8mm." 

3.3 ADDENDUM TO USER'S GUIDE, VERSION 1.4 FOR DOS
    The section in the Addendum entitled "Running 
    Sytos Plus on Systems with Windows 3.1 and Smartdrive
    4.0 Installed" is not applicable for this version of
    Sytos Plus.

3.4 LIMITATION WHEN USING A FIXED DISK AS A BACKUP DEVICE
    UNDER DOS 6.0 
    If you are using a Fixed Disk as a backup device for
    Sytos Plus, do not use the DOS 6.0 DoubleSpace disk
    compression feature.
