Subject: Proper Method for Running Benchmark and Diagnostics Programs
Date: 06/04/93
Page(s): 1 of 1
PSB No: S-0158
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.

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 MUX Adapter card, the High
Density Controller card and the 3.5” 720KB/1.44MB external floppy drive from
Manzana Microsystems.
The MUX Adapter card was found to support the external floppy drive as a
720K floppy drive in the Equity I +. The instructions should be followed as
described in the MUX Adapter Card Manual, supplied by Manzana. No
alterations or special accommodations are necessary. Jumpers on the card
should be left at the factory default settings.
The High Density Controller card was found to support the external floppy
drive as a 1.44Mb floppy drive in the Equity I +. The instructions should be
followed as described in the High Density Controller manual. No alterations
are necessary.
The High Density Controller installation requires that the Equity I +‘s built - in
floppy disk controller be disabled. This is done by setting J1 on the Equity
I + main board to the “B” position. The 380KB floppy drive A: is then
connected to the High Density Controller, instead of the internal controller.
MS - DOS version 2.X or higher is required for installation of the High Density
Controller and use of the external drive as a 1.44MB floppy disk drive. The
Equity I + is shipped with MS - DOS 3.3, previously version 3.2.
Manzana includes the 3Five disk utilities with their MUX Adapter card and High
Density Controller card. These utilities include a device driver for the 3.5”
floppy disk drive, a format utility and information utilities for use with the
external 3.5” floppy disk drives.

Subject: Tape Backup System Test Results
Date: 6/13/89
Page: 1 of 2
PSB No: S-0087
Originator: MWT w
The Epson America Product Support Center has recently tested four tape
backup systems:
Archive VP - 150i
Mountain Series 4000 FileSafe
Tallgrass TG - 4060 +
Tecmar QT - 60e
Internal, 150MB
External, 40MB
External, 60MB
External, 60MB
The tape drives were tested on a variety of systems (please see the notes
below). In all cases, the drive manufacturer’s documentation was used as a
guide to installation and operation. Note that for 8086/88 computers, the
XT- type settings were used. For the 80286/386 computers, the AT- type
settings were used. This is important for correctly configuring the host
adapters or controller cards for IRQ, DMA and I/O port address.
Archive VP - 150i
The VP - 150i was tested on the Equity II +, Ill + and 386/20. Due
to the capacity and nature of the drive, it is not particularly suited
for use in any of the 8086/88 computers. This was the only drive
supplied with Unix/Xenix device drivers. It was tested under MS DOS 3.3 and SCO Xenix 286 System V version 2.2.1 with no
problems encountered. The VP - 150i is also Novell tested and
certified under the NetWare operating system.
Mountain Series 4000 FileSafe
The Series 4000 FileSafe was tested on the Equity II+, III + and
386/20. Due to the use of a 16 - bit controller, it was not tested
in any of the 8086/88 computers. It was tested under MS - DOS
3.3 with no problems encountered. A chapter is included in the
tape software documentation on backup and restore operations on
a local area network, including Novell.
PSB No: S-0087
Page: 2 of 2
Tallgrass TG - 4060 +
The TG- 4060+ was tested on the Apex, Apex +, Equity I +,
II +, Ill + and 386/20. It was tested under MS- DOS 3.2 and 3.3
with no problems encountered. There is no documentation on LAN
operations.
Tecmar QT - 60e
The QT- 60e was tested on the Equity I +, II +, III + and 386/20.
Testing was conducted under MS - DOS 3.3 with no problems
encountered. The Tecmar documentation includes extensive
information on installation and operation in a LAN environment.
General Notes
Of the four units tested, the Archive and Tecmar drives offered the
easiest installation. They also provided the best performance, with
the Tallgrass drive giving the slowest disk-to-tape and tape to- disk operations. All four drives were supplied with menudriven tape utility software for the MS - DOS environment.
Command-line and timed, scheduled operations are also
available. As previously mentioned, the Archive drive also included
device drivers for use in a Unix/Xenix environment, offering the
greatest level of flexibility.
Please contact the manufacturers for additional information.

Installation of either board in the Equity I + was quick and simple to do when
following the installation instructions accompanying the boards.
Installation of the SOTA 286i 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 286i 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 286i 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.

Our Computer Product Support Center receives numerous calls requesting
information and recommendations on 80286 Accelerator boards for use with the
Equity I and I + (8088 - based) and the Equity II (8086 - based) personal
computers.
We have found that the SOTA 286i and 286 Express products may meet your
requirements and are competitively priced! They join the PC Elevator board
(for use with the Equity I + and Equity II) as accelerator boards recommended
for use with Epson 8088 and 8086 - based personal computers.
Although these boards were tested by qualified product support specialists,
Epson America makes no representations that these third party products are
compatible with all hardware configurations or software applications.
We recommend that you certify these products with your specific hardware and
software requirements and consult with the third party vendor to ensure reliable
operation.

Operating System Network Driver Compatibility: All supported
network cards are tested with a NetWare driver designed
specifically for each card. To test accessibility of the driver
to the interface card, a workstation is attached and logged into
the file server and run through a series of NetWare and MS-DOS
commands.

Bridging: The file server is configured with different interface
cards at the same time. Whenever two or more driver configurations
are listed together in this report, it is an indication of bridge
testing and that the drivers and cards are functioning at the same
time.
ASYNC Communications Testing: Modems and telephone lines are used
to communicate between the file server and a remote workstation
using an asynchronous operating system driver and shell driver
controlling the serial ports.
Extended Hardware Testing: Novell Disk Coprocessor boards (DCB)
and Novell SCSI disk subsystem interface boards (DIB) are used
in the file server to connect Novell disk subsystems to the file
server. Note that the DCBs are only tested on the II+ and III+,
as they are only compatible with the 16-bit AT-type bus.
Network printing is tested by sending a print job from a
workstation to a printer connected to the file server.
Workstation
Testing: In situations where only a workstation
driver is available, the system is tested as a workstation,
such as with the Novell Network Interface Cards (NICs).

I+/II+/III+/LT DIAGNOSTIC
"EXEC
failed"
MESSAGE
The purpose of this bulletin is to clarify the correct
usage of the DIAGNOSTIC DISK.
Many customers and dealers have contacted Epson's Technical
Support because of getting a "EXEC failed" error message
when trying to run the system diagnostics MEMORY test.
This occurs because many people are not booting the system
with the diagnostic disk but rather loading the diagnostic
program after booting from the MS-DOS system disk or hard
disk drive.
In the instructions for performing system
diagnostics the following statement is made:
Note:
To run the System diagnostics, boot your system with
the diagnostics diskette in drive A.
Then select
option 4 from the OPERATION menu. If you start this
program in any other way, some tests may produce
strange results.
The "EXEC failed" error message will not occur if the
diagnostic diskette is properly loaded,
Please note that the diagnostic diskette should not
modified in any way or similar results may occur.
be
If the diagnostics diskette was obtained through Epson
America's Training Department and does not contain the
system files then the system files should be copied to
the diagnostics disk before attempting to run the
diagnostic
programs.

What is Expanded Memory?
Conventional memory, managed by MS - DOS, is limited to 640K. In
response to the need for greater amounts of accessible memory, the
LIM EMS (Lotus/Intel/Microsoft Expanded Memory Specification) was
introduced in 1984. EMS, version 3.2, provides usable memory
beyond the 640K limit through “bank switching”. The expanded
memory is divided into 16K portions called “pages”. The computer
accesses these pages through a “page frame” or “window” which is
64K of memory located between 768K and 896K in 80286 - based
systems and between 800K and 960K in 8086 - or 8088 - based
systems. 16K pages of memory are allocated for an application’s
use and the EMM (Expanded Memory Manager) handles the job of
mapping the pages in and out of the page frame as they are
needed. However, in order to make use of expanded memory, the
software must be written to take advantage of the EMS. Software
such as Lotus 1 - 2 - 3, Microsoft Windows and Borland’s SideKick
Plus make use of expanded memory. EMS is limited to 8Mb of
expanded memory.
What is EEMS?
A superset of EMS, AQA EEMS (AST/Quadram/Ashton - Tate
Enhanced Expanded Memory Specification) provides greater flexibility
in the mapping of expanded memory. However, it also uses the
technique of “bank switching” and has its own memory manager
which accommodates such specially written software as Quarterdeck’s
DESQview. EEMS is also limited to 8Mb of expanded memory.

What about the 155Mb RAM listed as the maximum for the Equity
III +?
This larger amount of RAM is the maximum usable memory range
for an 80286 microprocessor and generally refers to extended
memory. Extended memory starts at the 1Mb boundary and extends
out to 16Mb. As it requires a 24 - bit address to access memory in
this range, extended memory is handled by the protected mode of
the 80286. Examples of currently available software that can switch
into protected mode to use extended memory are Framework II,
AutoCAD, the VDisk RAM disk and Xenix OS.
How does LIM EMS 4.0, the latest version, differ from the earlier
version, LIM EMS 3.2?
EMS 4.0 supports up to 32Mb of expanded memory where EMS 3.2
supported only 8Mb. EMS 4.0 has been changed to make it easier
for applications to share expanded memory. In EMS 4.0, page
mapping has been streamlined and new functions allow application
programs to dynamically increase and decrease the amount of
expanded memory allocated to them. In previous versions of EMS,
the page frame was located in an unused 64K block of memory
between 640K and 1Mb. EMS 4.0, subject to limitations in the
system hardware, supports the page frame anywhere in the first 1Mb
of memory. Before EMS 4.0, the page frame held four pages. Now
you can define a page frame of up to eight pages in memory above
640K. The size of the page frame is limited only by the amount of
available memory. There has also been a change to support the
smaller than standard (16K) memory pages used by some expanded
memory boards.
Is EMS 4.0 compatible with my old expanded memory board?
The EMM 4.0 driver works with existing hardware. You don’t need
to buy a new expanded memory board. However, until you use
applications that have been written to take advantage of EMS 4.0,
you probably won’t notice much improvement in performance over
your older version.

Q12.
A.
How do you expand the memory of the Equity 386/20?
Memory expansion in the Equity 386/20 can be accomplished by
adding SlMMs (single in - line memory modules) to the CHET - RM
board. Both 256K and 1Mb SlMMs are available from Epson
America. The 256K SlMMs are sold in 1Mb kits and the 1Mb
SlMMs are sold in 2Mb kits. Compatible third party 1Mb SlMMs are
available from Matsushita, Toshiba and CDC Enterprises. You can
also use third party memory expansion boards such as those listed
above for the Equity II +/Ill +.

Refer to PSB S - 0095 for 18MB RAM Setup information.
Q14.
Is there a driver supplied with the Equity 386/20 to allow the use of
the extended memory as expanded memory?
A.
Yes, the Equity 386/20 system software includes the device driver
EEMM386EXE. This driver emulates LIM EMS 4.0 memory using
the extended memory supplied by the additional SIMMs. It will
support only the onboard memory above 1 MB, up to 15MB. This is
the maximum memory that can be installed on the CHET- RM
board. It will not support memory installed on memory expansion
boards.
Q15.
Are there any expanded memory boards that are compatible with the
Equity LT?
A.
No, the option slots on the LT require a special connector. The
hard drive controller and the LT cartridge modem are the only option
cards currently available from Epson America.
Q16.
What expanded memory boards are compatible with the Apex by
Epson?
A.
The Above Board PC from Intel Corporation has been tested by
Epson in the Apex.

Q17.
Are there any general guidelines for determining the chip speed to
install on the memory expansion boards?
A.
Yes, if the CPU speed is 8MHz or less, use 150ns RAM chips. If
the CPU speed is 10/12MHz, use 120ns RAM chips.
Q18.
Is there anything that should be kept in mind during the installation
procedure for the memory expansion boards?
A.
Yes, when installing the memory boards in the Equity II + and Equity
Ill + (12MHz models), remember that the bus speed is 12MHz. For
example, the Intel Above Board 288 and Above Board Plus allow
you to set up the bus speed and chip speed in their installation
programs.
Q19.
What is meant by backfilling memory when using software such as
DESQview?
A.
Backfilling is a function of many expanded memory boards which
allows a portion of the board’s memory to be used as conventional
memory. In this way, you could turn a 256K system into one with
840K memory or more. In certain situations, you may want to
disable some of the computer’s conventional memory and the use
the memory on the expansion board (i.e. DESQview).
Q20.
Which Epson computers have memory settings that allow backfilling
memory?
A.
The Equity I, Equity I +, Equity II + and Equity Ill + allow backfill.
The Equity I comes with 256K standard and the Apex comes with
512K, thus allowing backfill. The Equity I + has DIP switch settings
allowing system memory to be disabled to 256K or 512K. The
Equity II+ and Equity Ill + have jumpers on the system memory
boards to allow memory to be disabled to 256K and 512K.

A. Yes, the Equity It computer can be used internationally by
selecting the appropriate input voltage on the voltage
selection switch located on the rear of the unit. It will
operate on either 115VAC or 230VAC at 50/60 Hz power.
One thing to be aware of is that the voltage on the power
outlet on the rear of the computer is the same as the input
voltage of the computer. If you have a monitor or other
device plugged into this outlet make sure it is capable of
operating on the same voltage and frequency that the
computer is connected to. Most monitors and printers are not
set up to operate on dual voltages and will be damaged if
plugged into the wrong AC voltage. This applies to the Epson
monitors and printers as well.

Microsoft Word, certain Equity computers and a serial printer. The
situation exists on:

When Word is configured to drive a serial printer via COM1 or
COM2, it will print a character every 1 to 2 seconds. A single line
of text may take up to a minute to print.
(serial output)
Word uses BIOS interrupt 14h
function 1 (send
character to port) for driving either COM port. The function number
is placed in the AH register and the interrupt called. On return, AH
is supposed to contain the line control status. However, AH is still
set to 1, indicating that a character is ready to be received. Word
then calls interrupt 14h, function 2 (receive character) and attempts
to receive the character. After 1 to 2 seconds, the routine times out
and transmission is resumed.
There are three methods of correcting this situation:
1)
If the printer supports hardware handshaking, redirect
the printer output (MODE LPT1:=COM1:) and configure
Word for LPT1. This works reliably with Epson printers
or similar devices.
2)
Epson has developed a patch program (SERFIX.COM).
This is a TSR that insures that proper status is
returned from INT 14h,
function 1. This program is
CompuServe
(Epson and Microsoft
available
from
Forums) and the Product Support Center BBS.
3)
A revised ROM BIOS has been developed for 'the above
systems. This is a limited release and will only be
supplied on an as-needed basis.
Method 1 is the easiest solution. Method 2 is effective and is
recommended for individual users. Method 3 should be reserved for
large, multi-unit upgrades on an as-needed basis.
Please contact the Systems
information.

PARALLEL PORT SETUP
The purpose of this bulletin is to provide information on the setup procedure which is required to allow correct operation of the
parallel port when using an Epson MULTI-MODE graphics card (MGA #
Q205A-AA) with the Equity It.
Although the MGA card does not have a parallel port physically
located on the card, it does contain the address location for
LPT1. When the system DIP switches are set to enable the primary
parallel port (DIP switch set 2, 1 OFF - 2 ON), LPT1 is selected
and the system tries to send the parallel
printer data to the
video board.
In this case it would appear as though the parallel
port is not working as the printer will not print.
When using the MGA video card with the Equity It,
the parallel
port DIP switches
should be set
in the SECONDARY position (DIP
switch set 2, 1 OFF - 2 OFF).
This will designate the Equity It
built in parallel output port as LPT1 and will allow the parallel
printer port to operate correctly.
An undocumented DIP switch setting exists (DIP switch set 2, 1 ON
and 2 OFF) which allows the built in parallel port
to function as
LPT2.

Recently, four leading vendors of communications products have issued
certifications of compatibility for the Epson Equity series of PCS. The products
range from local-area networking to multi-user applications to micro-tomainframe connectivity.
Arnet Corporation
Arnet Corporation produces multi-user expansion boards that allow terminals to
be connected to PCs using multi-user operating systems. They have certified
the Equity I+ and III+ for use with their products.
A typical configuration would be an Equity III+ host, the Xenix operating
system, an Arnet Multiport Multi-8 board and cabling to connect other PCs
(such as the Equity I+) or standard ASCII terminals. Other compatible
operating systems include Microport Unix, Theos, BOS, PC MOS and Others.
The Arnet Twin port offers 2 serial ports for smaller installations.
Multiport board is available in Multi-4 or Multi-8 configurations, and
Multi-4 can be upgraded; The Smartport is an intelligent version of
Multiport that uses the 80186 processor to handle heavy data transfer.

COMPATIBILITY
S-0012
The purpose of this bulletin is to provide information regarding
style Equity Plus series
the compatibility of the enhanced "AT"
keyboard with the Equity
family of computers and a general
statement on software support.
With the introduction of the Equity It and III+, Epson brought out
an enhanced keyboard design - very similar to the enhanced
keyboard introduced by IBM on the Model 339 AT. There are a couple
of areas to make note of.
1.
Keyboard
Compatibility
The enhanced keyboard cannot be used on an Equity -‘I, II or
III. The enhanced keyboard (as with
IBM's) requires explicit
ROM BIOS
support. The Equity It and Equity III+ incorporate
this support; the earlier machines do not.
It is possible, however, to use a third-party "enhanced-style"
keyboard (such as the Datadesk Turbo-101) which offers switch
selection for PC/XT or AT usage.
(Please note that early
versions of the Equity I and II did not support any third
party
keyboards.)
The
correct
jumper
Equity I:
Equity II:
settings
for
non-Epson
keyboards
are:
J2 and J3 jumpered
J 3 , J4 and J5 set for position 1
Also note that once the above jumper changes
have been made,
attempting to use the Epson keyboard will result in damage to
the keyboard-and main board.
2.
Software
Compatibility
Not all
applications "know"
about the enhanced keyboard. The
and mapping are subtly different. If you experience
scan codes
difficulties with certain applications
(particularly any that
re-program the keyboard), contact
the software vendor and ask
about enhanced keyboard support.

A documentation error has been identified in the MS-DOS version
3.2 manual which is supplied with the Equity It and III+, there is
an error in the documentation for the SELECT command. This error
also occurs in the HELP utility data file.
In the respective sections
the syntax is given as:

SELECT C: 001 US
Also,
in the HELP utility, the format is given as:
SELECT [DOS source

So - there are two solutions. One is to use the "traditional"
method for logical formatting:
