----------------------------------------------------------------
STARTING THE BENCH.EXE PROGRAM
------------------------------
To run the main benchmarks program:
. make the directory containing the
benchmark programs the current
directory.
. type "BENCH" (without the quotes).
You may use the following command line parameters:
GO bypasses the initial logo screens.
AUTO starts the benchmarks in automatic mode. The processor tests
will cycle through one at a time. This option uses the
BENCH.KEY file. NOTE: A reboot is required to end AUTO mode.

legibility on laptop computers.
For example, "BENCH GO" will execute the benchmark program and bypass
the initial logo.
MENU OPERATIONS
FILE MENU
---------
The "Save results" selection allows you to save the test results in a
file on your disk. You will have the ability to change the machine
description (See SET MENU) and the name of the file. The file will be
saved in the current directory and will overwrite an old file with the
same name. Be sure not to use the same file name when running the
MicroScope utility.
The "Save results to .CSV" selection is similar to the "Save results"
selection except that the data is stored in comma delimited format for
importing into a database or spreadsheet program. A machine id is
requested and will appear in each record so that the records for
individual machines can be located if they are loaded into a combined
database file.
The "About" selection tells about the benchmark program. The people
involved with the project over the years as well as the languages and
tools used to create the programs are listed.
The "Quit" selection terminates the benchmark program.
VIEW MENU
---------
The "Results" selection allows you to browse through the test results
on the screen. The format is the same as the results file. You can
scroll up and down using the arrow, PgUp, PgDn, Home, and End keys.
Use the Esc key to return to the main menu.
The "System Info" selection executes MicroScope - PC Labs' System
Information Utility. You have the ability to enter a file name for
MacroScope to save the description of the current configuration
of your machine. Be careful not to use the same file name you for
saving the results to disk.

code in a loop and writing files at regular intervals. After the
battery is completely drained, the result of this test can be found
in the files RUNDOWN.001, RUNDOWN.002, and RUNDOWN.003. The longest
duration noted in these files is the result.
COMPATIBILITY MENU
------------------
The selections on this menu test the compatibility of a piece of
hardware against a published specification. At this time there is only
one choice on this menu.
The "VGA Hardware" selection is only valid if you have a VGA graphics
device. It tests your VGA adapter against the IBM standard. Any
deviations from the standard do not necessarily indicate a defective
or unusable board. Many application programs do not use all the
available features and may also contain code to correct for
deficiencies in your particular device.
QUALITY MENU
------------
The selections on this menu represent tests which must be interpreted
by the individual user. At this time there is only one choice on this
menu.
The "EGA/VGA Monitor" selection allows you to display various test
patterns on your EGA or VGA Monitor using different display modes. The
results will depend on your tastes with respect to size of characters,
text readability, brightness, and contract as well as color
perception.
SET MENU
--------
The "Enter info..." selection allows you to enter a name for the
machine being tested. Up to 25 characters are available. The name you
enter will appear on results screens as well as in the results file.
HELP MENU
---------
The "Help" selection presents a menu of help topics. Select the topic
to view and hit the Enter key. Hit the Enter key again to return to
the menu.
The "Timer accuracy" selection allows you to test the accuracy of the
internal system timer. By comparing the internal timer to an external
time base, such as a stop watch, you can see if the results derived by
the tests are valid for your machine. A correction factor is displayed
to allow you to adjust for any inaccuracies in your timer.
