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.

The Equity models tested were the Equity I, Equity II Equity I + and Equity le.
The Apex models tested were the Apex, Apex Plus and Apex 100. All were
tested with Norton Utilities and MS - DOS.
The table below shows compatibility and the Norton SI rating of the
various systems.

Installation of the board in most of the units was quick and simple to do when
following the installation instructions accompanying the boards. Installation of
the SOTA 386si in the Equity I and the Equity II is rather difficult. Due to the
amount of disassembly required, we strongly recommend that only Authorized
Service Centers install the board in the Equity I and Equity II.
Installation Instructions
Equity I
1. Remove the following from the main unit:
a) upper case
b) rear panel
c) front panel
d) FDD/power supply block.
2. Follow instructions for a standard installation for the SOTA 386si in an
8088 - based system.
Take care to fold the SOTA connector cable so as
not to prevent reassembly.
The cable is sturdy and will tolerate being
folded.
3. Reassemble the main unit and go through the testing and initialization
procedure outlined in the SOTA manual.
Equity II
1. Remove the following from the main unit:
a) upper case
b) rear panel
c) front panel
d) FDD/power supply block.
2. Follow instructions for a standard installation for the SOTA 386si in an
8086 - based system.
Take care to fold the SOTA connector cable so as
not to prevent reassembly. This will necessitate routing the cable so that it
does not conflict with the power connection to the main system board.
The cable is sturdy and will tolerate being folded.
3. Reassemble the main unit and go through the testing and initialization
procedure outlined in the SOTA manual.

With the increasing affordability of EGA and VGA boards in the marketplace,
there has been a related increase in requests for compatibility information
regarding the Equity II computer and these video boards. This bulletin is
designed to give a list of tested VGA boards and recommendations for
installation of both EGA and VGA boards in the Equity II.
To date there has been no report of incompatibility between EGA boards and
the Equity II.
The key to a successful installation is to make sure that
jumpers J1 and J2 on the system board are both in the default position
(position 2), and that the system DIP switches are set for NO MONITOR (1 - 5
and 1 - 6 both up).
The following VGA boards have been found to be compatible in the Equity II.

The 16 - bit VGAWonder board from ATI has been found to be incompatible
with the Equity II. It prevents the system from completing the boot procedure.
As with the EGA board installation, it is necessary to make sure that jumpers
J1 and J2 are in the default position (position 2) and that the system DIP
switches are set for NO MONITOR (1 - 5 and 1 - 6 both up).

NOTE:
The recommended switch settings for the OmniBridge controller are
as follows:
1-1 DOWN 2-1 DOWN
1-2 DOWN 2-2 DOWN
1-3 DOWN 2-3 UP
1-4 DOWN 2-4 UP
These settings select NO ADDRESS for the OmniBridge BIOS and
allow it to coexist with the internal FDC of the computer in which it
is being installed.
This way you do not need to disable the internal
FDC or connect any cables from the OmniBridge to internal floppy
drives. This was found to be a universal setting for all of the
computers listed above as compatible with the OmniBridge controller.

The purpose of this bulletin is to provide information on the various keyboards
used with the Apex, Apex Plus and Equity series computers and the part
numbers of the keyboard subassemblies used with these keyboards.
The Apex and Apex Plus computer keyboards are to be replaced as whole
units.
The Equity series keyboards are repaired to the subassembly level.
The
Equity III keyboard PCB assembly is the only one that comes with the key top
set attached.
Since some of the keyboards have the same model numbers, the difference
can be determined by the FCC ID number in those cases.
The chart below provides a quick reference to determine the part number of
the main keyboard PCB assembly, key top set, control logic subassembly, and
keyboard cable.
