                                 TESTING

   You should make the appropriate selections from the first four menu
   panels before you proceed to Run Tests.
                                 
   SELECT PERIPHERALS
   This selection permits you to configure the parallel (LPT) and
   serial (COM) ports on your computer.  The parallel ports may either
   have No Device, a Printer, a loopback plug (see User's Guide), or
   another type of device attached.  If a printer is attached you may
   specify whether it is compatible with Epson (most dot matrix
   printers), HP LaserJet (Most laser printers) or PostScript (many
   desktop publishing printers).  The Serial Ports  may have the Port
   Device specified (no device, modem, mouse, printer, loopback plug or
   other device attached), Baud Rate (data transfer speed from 110 to
   19200 bits per second), Parity (space, mark, even or none), Data
   Bits (5, 6, 7 or 8), and stop bits (1 or 2).  The initial settings
   are correct for many devices.

   If you're having problems, experiment with changing speed first,
   then parity.  Use of COM Debug will help you in getting the COM
   ports set up properly.
 
   RAM TEST CONTROL
   Controls the memory test parameters for the memory tests run under
   the RUN TESTS option in the Testing menu.  You may select the memory
   block to be tested, as well as the number of actual diagnostic
   memory tests to be run.
 
   PAUSE CONTROL
   Controls whether there is a pause at the end of each test, when an
   error is encountered, or no pause at all.  If you are running the
   tests unattended with logging on (see below), you may set pause to
   off so that the tests will continue to run.
 
   PASS CONTROL
   You may set the number of passes (test cycles) to one or 10 passes.

   ERROR LOGGING
   Error logging may be set to send the error information to a text file 
   (QA_LOG.TXT), to the printer (LPT1), to a Com port (COM1), to a file,
   or to turn off logging. Unless you have known disk problems, it is 
   usually most convenient to log errors to a file which may then be 
   printed or displayed.

   TEST LOG MODE
   Error logging mode may be set to Errors Only or Full Logging, 
   allowing "errors only" logging if desired.

   RUN TESTS
   Run Tests displays a box which contains all the tests available for
   the hardware you have installed on your computer. The tests are
   organized into test groups (Main Components, Video Adapters, Floppy
   Drives, Hard Drives, COM Ports, Parallel Ports, Printers, and RAM
   Tests.  All tests are normally selected.  If you wish to bypass a
   particular test, use the up and down arrows to highlight the test
   group then the horizontal arrows to highlight the test, then press
   the space bar.  The >> indicator will disappear from beside the
   test.

   If you wish to discontinue the tests, press the Esc key.  You will
   be given a choice of Quit Batch, Quit Test, Help Menu or Continue.
   Quit Batch will discontinue all subsequent tests that were selected.
   Quit test will discontinue the test group selected.

   THE TESTS ARE:

   MAIN COMPONENTS
          CPU  - Central processing unit
          NPU  - Numeric co-processor unit
          INT  - Interrupts
          TMER - Timer
          DMA  - Direct Memory Access
          CCLK - CMOS clock
   
   VIDEO ADAPTERS
          MDA  - Monochrome display adapter
          CGA  - Color graphics adapter
          EGA  - Extended graphics adapter
          VGA  - Video graphics array

   FLOPPY DRIVES A: AND B:
   These tests are non-destructive.  You must insert a blank, formatted
   disk in the drive.  The diskette must be formatted to the drive's 
   maximum capacity (e.g. do not use a 360K diskette in a 1.2MB drive).
                                              
   HARD DRIVES C: AND D:
   These tests are non-destructive and test only the ability to read
   data from the hard disk using a variety of different seek patterns.
                                              
   COM PORTS COM1: - COM4:
   These tests test the ability to communicate through the serial
   ports.  For the most complete testing, use a Serial loopback plug
   and specify loopback for the COM ports in Select Peripherals above.
   COM3: and COM4: require DOS 3.3 or later.
   
   PARALLEL PORTS LPT1: - LPT3:
   These test the ability to cummunicate through the parallel ports.
   For the most complete testing, use a Parallel loopback plug and
   specify loopback for the LPT ports in Select Peripherals above.
   
   PRINTERS
   If any of the COM or LPT devices are specified to be a Printer, a
   test pattern will be directed to the printer.
   
   RAM TESTS
   These thoroughly test the Random Access Memory by using a variety of
   patterns written and read.  In addition the memory bus is checked
   for sensitivity to noise.  If you have expanded or extended memory
   it is checked also.  The complete RAM tests usually require some
   time to complete, based on the speed of your computer, so the area
   of memory being tested is displayed as the tests progress.  If you
   have insufficient memory to run the tests, you will be notified.  If
   this is the case, you should temporarily rename the config.sys file
   on your boot drive (A: for floppy disk, C: for hard disk) and reboot
   the computer.
   
   IMPORTANT: Never try to repair or replace any potentially defective
   component(s) yourself unless you are familiar with the proper
   procedures and safety precautions for servicing the particular
   component(s).
