Subject: Proper Method for Running Benchmark and Diagnostics Programs

Page(s): 1 of 1
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.

Subject: Equity Series SIMM Compatibility
EPSON

Due to the influx of third party SlMMs on the market, there are some that are not
compatible with Epson products. This bulletin is intended to be an aid in ensuring
that only compatible SlMMs are chosen for use in Epson’s Equity Series of
computers.
The SlMMs in question were SEIMENS, CUMULUS and KINGSTON. Installing these
SlMMs in Epson products may cause the following errors:
Parity Check 1
18FFFE 0000 202 Memory Address Error
164 System Options Not
1500 E000 201” DOS RAM Address Error
It was thought that the chips used in these SlMMs were of poor quality.
Epson Portland evaluated the SlMMs in question and found that this was not true.
The problem is caused by the SIMM circuit boards (ITE and TECAP circuit boards)
used to manufacture the SIMM modules. The dimensions of these boards are not
compatible with industry standard SIMM sockets. This may result in incomplete
contact between the SIMM assembly and it’s socket. This is caused by insufficient
size of the contact surfaces in these products. Also enlarged holes in the TECAP
product allow the component pin to pass entirely through the hole without making
contact.

It is recommended that only SIMMS meeting industry standard contact surface
specifications be used in Epson Equity computer products.
Some recommended SlMMs that were tested and found Compatible are:
Toshiba
Matsushita
CDC Enterprises
Samsung
Aculogic

As computing environments increase in complexity, there has been an increasing
number of instances that require the support of several printers by one computer.
One common example is that of using Novell Netware’s print server capabilities to
provide printer access to a large group of users with differing printer requirements.
Netware is capable of supporting three (3) parallel and two (2) serial printers on one
server. Recent testing has shown that the Equity 386/25 Plus, Equity 386/25, Equity
386/20 and the Equity 386SX Plus will support three (3) parallel ports along with two
(2) serial ports. The key factor in providing support for a third parallel port is the
need for a parallel interface card that can be set to the IBM Monochrome
Graphics/Parallel printer I/O address at 3BCh. The computer looks for this address
first and, if present, will assign the parallel port on that card as LPT1. The built-in
parallel port (I/O address 378h) will then be addressed as LPT2. We also had an
AST I/O Mini serial/parallel card addressed at l/O address 278h, which was then
reassigned to LPT3. Each of the three parallel ports was attached to a printer. There
was also a printer attached to each of the two serial ports. All five printers were then
set to print simultaneously under Netware Version 2.15 Rev. C using PCONSOLE. All
five printers were able to print the documents assigned to them, simultaneously. The
units were then tested using WordPerfect 5.1 on the network and again were
successful in printing to the five (5) printers at the same time. The last tests were run
with the units booting under DOS 4.01 and screen prints being directed to each of
the printers. WordPerfect 5.1 was also used to direct documents to each of the
printers. Again all five (5) printers were able to print the files that were sent to them.

Although not all Equity computer models were tested in this situation, the Equity
models 386SX, lIe, Ill+ and II+ should work in a similar manner if the instructions
above are used as a guide. There is one item of which to be aware when using the
this setup and that is the system will complete the RAM count and lock up if using a
monochrome monitor. If you need to use three parallel ports, USE A COLOR
MONITOR.

Q1.
Equity 386/25 PLUS Questions and Answers
What microprocessor does the Equity 386/25 PLUS use?
A.
The Equity 886/25 PLUS utilities the Intel 80386/25 DX microprocessor
running at 8 or 25Mhz. Use of this CPU gives you 386 performance and
compatibility in a 16-bit based computer architecture.

Q2. What speed does the Equity 386/25 PLUS operate at?
A.
The Equity 386/25 PLUS operates at either a 8Mhz or 25Mhz processor
speed. The speed can be set by using the CPU speed switch located on
the front of the machine. At either processor speed, the system bus
operates at a fixed speed of 8Mhz.

Q4.
A.
What is
The Equity 386/25 PLUS is capable of operating at 8MHz or 25MHz. Some
copy-protected applications require the computer to run at 8MHz
accessing the program diskette. By enabling the Auto speed function the
computer automatically switches to 8MHz when accessing the diskette
drive. It then switches back to 25MHz for optimal performance. Auto
speed is accessed through the SETUP program under the Auto speed
option.
Does the Equity 386/25 PLUS use the Phoenix or Award ROM BIOS?
No. All Equity desktop computers utilize a Seiko-Epson proprietary ROM
BIOS.
