- 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).
