  IBM Enhanced Diagnostic Diskette
  Version 2.0.453
  PN 37L2021

      Description

      The IBM Enhanced Diagnostic Diskette is a self-booting
      DOS-based diagnostic utility  used to detect failing
      hardware components.

      IBM, in conjunction with Watergate Software, the makers of
      PC Doctor diagnostic software, has developed a highly effective
      diagnostic application designed specifically to support the
      IBM PC 300, 700, and Intellistation Series product family.

      What's New Version 2.0.453:

      NEW TESTS:

      Iomega Zip Drive Test
      --------------------
      Use this test to test the Iomega zip drive and drive
      interface.

      Default test include the following tests.
        Controller
        Max Seek (50 times)
        Random Seek (300 sectors)

        It takes about 20 seconds to run.



      Starting the IBM Enhanced Diagnostics Program

        To start the program:
        1. Shut down and power-off the system.
        2. Wait 10 seconds.
        3. Insert the IBM Enhanced Diagnostics Diskette into diskette drive A.
        4. Power-on the system.
        The initial diagnostics menu will be displayed.


      Navigating Through the Diagnostic Programs

        Use either the mouse or the keyboard to navigate through the
        Enhanced Diagnostics program.

        - Use the cursor movement keys to navigate within the menus.
        - The "Enter" key is used to select a menu item.
        - The "Esc" key is used to back up to the previous menu.
        - For online help select F1.

     Running Diagnostic Tests

        There are four ways to run the diagnostic tests:

        1. Using the cursor movement keys, highlight "Run Normal Test"
           or "Run Quick Test" from the Diagnostics Menu and then press
           "Enter".

           This will automatically run a pre-defined group of tests from
           each test category.  "Run Normal Test" runs a more extensive
           set of tests than does "Run Quick Test" and takes longer to
           execute.

        2. Press "F5" to automatically run all selected tests in all
           categories.

        3. From within a test category, press "Ctrl-Enter" to
           automatically run only the selected tests in that category.

        4. Using the cursor movement keys, highlight a single test within
           a test category and then press "Enter".  This will run only
           that test.

        Press "Esc" at any time to stop the testing process.

        Test results, (N/A, PASSED, FAILED, ABORTED), are displayed in
        the filed beside the test description and in the test log.

     IBM Advanced Memory Diagnostics

        The IBM Advanced Memory Diagnostics provide the capability to
        identify a particular memory module (SIMM/DIMM) which fails
        during testing.
        Use the System Board Layouts section in the latest PC 300/700,
        IntelliStation Hardware Maintenance Manual (HMM) to reference
        the memory sockets, or select "F1" twice to load the Online
        Manual and select Chapter 11 'SIMM/DIMM Locator'.

        Follow the steps below to locate the IBM Advanced
        Memory Diagnostics test options.

        1. Select the DIAGNOSTICS option on the toolbar and
           press "Enter".
        2. Highlight either the 'Memory Test-Full' or 'Memory Test-Quick'
           option and press "Enter".


        Memory Test-Full

        The full memory test will take about 80 seconds per MB of memory
        and will detect marginal, intermittent, and solid (stuck)
        memory failures.

        Memory Test-Quick

        The quick memory test will take about 20 seconds per MB of memory
        and will detect solid (stuck) memory failures only.

        Notes:

        Either level of memory testing can be performed on all memory
        or a single SIMM/DIMM socket.

        Only sockets containing a SIMM or DIMM can be selected for testing.
        Unpopulated sockets are noted by "........" besides the
        test description.


        Viewing the Test Log

        Errors reported by the diagnostic test
        will be displayed by the program as a failed test.

        To view details of a failure or to view a list of test results,
        do the following from any test category screen:


        - Press "F3" to activate the log File
        - Press "F3" again to save the file to diskette or F2 to
          print the file.





       Quick and Full Erase - Hard Drive

       The IBM PC Enhanced Diagnostics Program offers two hard drive
       format utilities:

       - Quick Erase Hard Drive
       - Full Erase Hard Drive


       -------------------------------------------------------------
      | Important                                                   |
      | _________                                                   |
      | Make sure all data is backed up before you erase the        |
      | hard drive.                                                 |
       -------------------------------------------------------------



      The Quick Erase Hard Drive provides a DOS utility that performs the
      following:

      - Destroys the Master Boot Record (MBR) on the hard drive.
      - Destroys all copy of the FAT Table on all partitions (both
        the master and backup).
      - Destroys the partition table.
      - Provides messages that warn the user that this is a non-recoverable
        process.

      The Full Erase Hard Drive provides a DOS utility that performs the
      following:

      - Performs all the steps in Quick Erase.
      - Provides a DOS utility that writes random data to all sectors
        of the hard drive.
      - Provides an estimate of time to completion along with a visual
        representation of completion status.
      - Provides messages that warn the user that this is a non-recoverable
        process.


     To select the Quick Erase or Full Erase Hard Drive utility:

     - Select the UTILITY option on the toolbar and press enter.
     - Select either the QUICK ERASE or FULL ERASE HARD DISK option
       and then, follow the instruction.
