Product Support Bulletin
Subject: Proper Method for Running Benchmark and Diagnostics Programs
Date: 06/04/93
PSB No: S-0158
Page(s): 1 of 1
Originator: MWT
This bulletin describes the proper method for running any benchmark or diagnostics
programs. This applies to any computer system.
In most cases, the computer should be started using an MS-DOS boot diskette
that’s ‘clean’ -
in other words, one with no CONFIG.SYS or AUTOEXEC.BAT files.
The appropriate executable can then be run, either from diskette or hard drive.
There will be some exceptions to the above rule. In attempting to benchmark or
troubleshoot any add-on that requires a device driver (CD-ROM, local area network,
etc.), obviously the necessary device driver(s) must be loaded. Also, some
programs will require a minimum number of FILES or BUFFERS to be defined in
the CONFIG.SYS file. Such programs will usually display this requirement if they
are run without the necessary CONFIG.SYS file.
For the most consistent results, use the absolute minimal boot configuration that’s
allowed by the hardware being tested.
