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.

Subject: Equity le - Early ROM BIOS Problem with Miniscribe 8425F
Date: 10/10/90
PSB No: S-0124
Page(s): 1 of 1
Originator: REM
A problem has been reported in the Equity le when using ROM BIOS versions earlier
than release 1.76. This version has been used in production units since September
1989. The Miniscribe 8425F hard disk drive may generate a “1701" error message
when a cold boot (power switch OFF and ON) after a warm boot (software reset or
pushing the reset switch) is executed.
When the warm boot is executed, BIOS writes the status of the warm boot to the
ROM BIOS scratch register. When a cold boot is executed after a warm boot, BIOS
should erase the status in the scratch register, however, the early BIOS does not
erase the status. The BIOS reads it as a warm boot and executes the POD, skipping
the video check and the RAM check and checking the hard disk directory. This
happens too fast for the Miniscribe 8425F hard disk drive to get ready for the BIOS
check, so it shows the “1701 error message. In the case of the warm boot only, the
hard disk is already ready, so no error message is generated.
lf this problem is encountered, run the ROMBIOS program and check the ROM BIOS
version to determine if the system needs the current version of BIOS release 1.76.
Please refer to ECN No. EQIE-005, dated 9/15/89, which described the EQUlTY le
ROM BIOS release 1.76 (CMTR-A06, -B06).

Lotus 1 - 2- 3 Graph Patch Program
Date: 6/26/90
Page: 1 of 1
PSB No: S-0121
When using Lotus 1
- 2- 3 (ver. 2.01) with the Hercules Monochrome board
or an Epson MGA board set for monochrome mode, the system displays
garbage (usually a checker board pattern) when using graphics. This also
occurs if the 90 x 25 text mode is selected in the Lotus INSTALL program,
since Hercules graphics mode is utilized.
The solution for this problem is to disable the internal MCGA video by
creating and using the program listed below. Run the MS - DOS supplied
DEBUG program and type in the following:
.
f
-A
xxxx:0100 in AL,65 ;
xxxx:0102 and AL,FB ;

Edit CX register.
Currently contains 0000.
Specify 8 bytes to be saved.
Save program to disk.
Quit DEBUG.
Note: xxxx segment value will vary depending on system memory usage.
The MCGADIS.COM program can now be found in the current directory. It can
be added to the AUTOEXEC.BAT file or run directly, before running Lotus.
This program will enable a Hercules Monochrome board or Epson MGA board
to be used in monochrome mode, but will not allow a CGA card to be used.

SOTA 386si from SOTA Technology, inc.
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.

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.

This bulletin is intended to provide the results of compatibility testing conducted
by the Computer Product Support Center with the PS/2 Connection Kit B,
PS/2 Adapter Board and the 5.25” 1.2MB external floppy drive from Manzana
Microsystems.
The PS/2 Adapter was found to support the external floppy drive as a 1.2MB
floppy drive in the Equity le. The instructions should be followed as described
on pages 14 and 15 in the PS/2 External Drive Manual, supplied by Manzana.
The only special accommodation necessary is the use of supplied adhesive
anchor pads and cable ties to secure the PS/2 Adapter board to the mounting
bracket for the DB - 37 connector. This procedure is also outlined on page 15
of the PS/2 External Drive Manual.
MS - DOS version 3.0 or higher is required for installation of the PS/2 Adapter
Board and use of the external drive as a 1.2MB floppy disk drive. The Equity
le is shipped with MS - DOS 3.3.
Manzana includes the XDrive disk utilities with their PS/2 Adapter card. These
utilities include a device driver for the external floppy disk drive, a drive letter
query utility and an information utility for use with the external 1.2MB floppy
disk drive.
