DESCRIPTION:  Creates the Drive Array Advanced Diagnostics utility diskette.
              The DAAD is a DOS-based tool for Compaq products with a SMART

              SCSI Array Controller using Fast-SCSI-2 drives. The two main
              functions of DAAD are to collect all possible information
              about the array controllers in the system and generate a
              list of detected problems.  This data can then be saved to a
              file for analysis. In most cases, DAAD will provide enough
              information to initiate problem resolution immediately.

Enhancements:

 - Changed the Inspect Menu's Logical Drive Status to only display the Spare to
   Replaced Map when there's at least one Active Spare Drive.

 - Enhanced the terminology displayed in the following field.
   "Drive Status:  Interim recovery (regenerating)"
   "Drive Status:  Recovering (rebuilding)"

 - Added reporting of Sense Posted-Write Cache Status bits 5-9

 - Added to the Error Report a check for a possible data corruption
   condition on SMART-2/E and SMART-2/P controllers with a 16M cache.
   This condition may occur when a 16M cache board is attached to a
   SMART-2 controller containing a firmware revision less than or
   equal to 1.36.

 - Moved "Not available" text to make screen easier to read.  This
   can be found in the Physical Drive Data selection on the Inspect Menu.

 - Added the detection of invalid logical drive configurations occurring on
   SMART-2/E and SMART-2/P controllers using firmware revisions <= 1.90.  This
   can happen when a single volume (made up of bus 1 id 0 and bus 2 id 0) is
   changed so that the drive on bus 1 is removed and the drive on bus 2 is
   moved to bus 1 id 0.

 - Added reporting of unused logical drives, but only when subsequent logical
   drives exist.

 - Added the display of drive array controller names for each slot in the EISA
   ID section of report.txt.

Fixes:

 - Fixed Posted Write error message.

 - Fixed invalid S.M.A.R.T. errors being reported on SMART-2/E and SMART-2/P
   controllers that were using firmware revisions <= 1.48.

 - Fixed Inspect Menu & Advanced Menu so that all menu selections are disabled
   when a controller is no longer physically present but is still configured
   in NVRAM.

 - Fixed SMART-2/E being incorrectly displayed as SMART-2/P on System View
   screen and Physical Drive Info screen.  This happens when a fully configured
   SMART-2/E is physically removed from the system without reconfiguration.

 - Fixed non-sequential logical drives being displayed incorrectly.  This
   happens when logical drives are initially configured in sequence
   (e.g. 1,2,3,4,5,6) and then one or more logical drives are removed
   (e.g. 2,4,6).

 - Fixed the drive array lettering (e.g. A,B,C) to always be sequential.
   Previously, drive array letters could be non-sequential (e.g. A,C) if any
   arrays were removed after initial configuration.

HOW TO USE:

1.  Obtain a formatted 1.44 MB diskette.

2.  Download the SoftPaq to a directory on your hard drive and change to
    that directory.  The file that is downloaded is an executable with a
    filename based on the SoftPaq Number above.

3.  From that drive and directory, execute the downloaded file and
    follow the on-screen instructions.  You will be prompted to insert
    the formatted diskette in a drive to create the diskette.

4.  After the diskette has been created, you may delete the SoftPaq file
    downloaded in step 2.

5.  The DAAD diskette is self-booting.  Place the diskette into your
    drive A: diskette drive and power cycle your system to start the
    DAAD utility.
