Subject: Proper Method for Running Benchmark and Diagnostics Programs

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’ ­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.

in other words, one with no CONFIG.SYS or AUTOEXEC.BAT files.

Manzana Microsystems, Inc. (Goleta, Ca.) has developed a product called the
DrivePort. It allows the removable “DataSafe” hard disk drive cartridges for the

Equity LT-286e and LT-386SX to be used on an AT- type desktop
computer. The subsystem consists of the 16 - bit DrivePort adapter card, the
DrivePort base unit and cable, a Y-configured power cable and a diskette
containing the QDRIVE.SYS device driver and utility software.

The DrivePort was tested using an Equity 386/25 desktop computer equipped
with two IDE hard disk drives, two floppy disk drives, a streaming tape drive
and a VGA video adapter.

The first step in the installation process is configuring the DrivePort adapter
card. The default jumper settings assign the DrivePort as an additional drive

(E1, E4 and E5 installed; E2, E3 and E6 removed). This is the setting that
was used. Note that it is possible to configure the DrivePort as the primary

(only) drive, but Manzana recommends against this for a number of reasons.
There are two other jumpers (W1 and W2) that determine the power source

for the adapter. When these jumpers are set in the A - B positions, the adapter
is powered by the Y-power cable. This cable must be connected to one of
the disk drive power cables from the power supply. Then take the small 4 - pin
connector of the Y-cable and attach to the matching connector J3 on the
adapter card. The third part of the “Y” is a male 4 - pin connector for powering
a disk drive, if all of the power supply wiring harness connectors are in use.

With W1 and W2 in the B - C positions, all power is supplied via the 16 - bit
system bus. This is the configuration that was tested.

Now the adapter card is installed in any available 16 - bit AT- type expansion
slot. Once installed, the cable from the base unit is attached to the DB-37
connector on the adapter card’s mounting bracket. This completes the

hardware portion of the installation.
