NCR Driver Versions
------------------------
    Current GCA SDMS Driver Versions (9/24/94):
      SDMSNET3-3.05.00          (for NetWare Version 3.1x)
      SDMSNET4-3.05.00          (for NetWare Version 4.xx)

    Current FCA ASPI Driver Versions (4/28/94):
      NETASPI3-3.03.00          (for NetWare Version 3.1x)
      NETASPI4-3.03.00          (for NetWare Version 4.xx)

    As of SDMS NetWare driver version 3.05.00, the specific
    version of the driver you are using can be obtained by
    executing the:
        MODULES
    command at the NetWare server console.

    In prior versions of the SDMS NetWare drivers, you need to
    note the driver version which is displayed on the NetWare
    system console at the time the SDMS NetWare driver loads.


SDMSNET Driver Error Logging
----------------------------
    With this current release of SDMS NetWare drivers, error 
    logging has been added to the driver.  If, for any reason, 
    a device I/O cannot be completed successfully (or experiences 
    unusual problems), a message will appear both on the NetWare 
    system console display and in the SYS:SYSTEM/SYS$LOG.ERR file.

    When contacting support, you may want to check for the
    existence and content of this file.

    There are several ways of accessing this SYS$LOG.ERR file.  

    1.) The simplest way to view this file is to simply log into 
        your Novell NetWare server from a client.  Map and
        change to the SYS:SYSTEM directory, then use your
        favorite text editor or utility to view the contents of
        the SYS$LOG.ERR file.
    
    2.) Login to the NetWare server from a client and use the 
        NetWare administrator's tools available under NetWare: 
            SYSCON for 3.1x,
            NETADMIN for 4.x under DOS,
            NWADMIN for 4.x under MS Windows
        select the "View File Server Error Log" option.   
        (This option is found under "Supervisor Options" under
         3.1x or "Manage Objects", followed by selecting the
         server name under 4.x) 
        Use PgUp/PgDn to examine the file, ESC to exit.
        An option will be given on exit to "Clear Error Log".
        The default is NO.  Select YES only if you want to
        wipe out all current information in the log file.

    3.) The following method is available, however, WE RECOMMEND
        THAT YOU *NOT* USE IT!
        From the NetWare console:
            load EDIT.NLM
        and specify:
                SYS:SYSTEM/SYS$LOG.ERR
        as the file to be edited.  If the error log file is small,
        you can use PgUp/PgDn to view the messages.  This method
        is NOT recommended because (apparently) the NetWare EDIT
        utility has a small buffer and truncates the view on the
        file without warning.  The result is that the most recently
        logged error messages will NOT be visible.

Release Version Notes
----------------------

The following enhancements have been made to the NCR SDMS Netware
drivers since the release of version 3.04.00.

  - Driver now supports NetWare for OS/2 (NWOS2).

  - Improve Error handling and error logging, including 
    explicit device identification in the error messages.

  - Device information displayed now includes more information, 
    including vendor, product ID, and firmware rev for each 
    device.

  - An NCRSDMS3.DDI file has been added.  While such a file is 
    not used by NetWare 3.1X, it is recognized by NetWare 4.XX
    installations.  This file simply directs the user to the 
    appropriate driver for NetWare 4.XX. 

  - The default I/O time-out period has been changed from 15
    to 30 seconds.

  - The timeout value for each pending io is now calculated on a 
    per device basis.  Formerly this value was a function of the 
    total number of outstanding IOs.

  - Improved support for applications which gain access to the driver 
    via the CAM interface.

  - Improved Tagged Command Queuing (QTag) support.

  - Changed QTag support to be ENABLE by default.  Also the default 
    qdepth has been changed to 10.

  - Improved Multi-LUN support

  - Increased maximum number of LUNs supported from 4 to 8.

  - Improved CD-ROM Support

  - New driver information options have been added:
        -h provides on-line help for options (without 
            loading the driver), and
        -v (verbose) provides visual feed-back of current driver
            options to the user (while driver is loaded).
        
  - New sort=disable" driver load option, allows for disabling 
    sort of read requests, which may yeild improved performance
    on certain devices.

  - Added "maxkb=NN" driver load option which allows for specifying
    the maximum block size which may be written to disk at one time.

  - Fix for third-party applications which accesss the driver via the 
    CAM interface.

  - Fix for driver failing to detect NCR PCI HBA(s) on certain systems.
    Driver would incorrectly display "Board Count=0" and fail to load.

For more information on driver load options and their use, please 
refer to the tuning guide, also included in this distribution.
