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.

Q1.
What is the Epson ExpressStation?
A.
The Epson ExpressStation is a computer that delivers excellent, cost
effective performance in a low-profile chassis. Incorporating several
controllers on the motherboard, the Epson ExpressStation provides a
number of on board resources that would otherwise require the use of
add-in I/O expansion cards. This integration delivers increased
functionality, increased reliability, and increased performance while
reducing the system power requirements and need for expansion slots. A
performance upgrade socket allows for easy upgrades in the field.
Additionally, two EISA compatible expansion slots deliver high
performance expandability. For a discussion on what an EISA computer is,
please refer to PSB No: S-0139.
Q2. What connectors are integrated on the motherboard ?
A.
The Epson ExpressStation comes standard with a built in IDE and SCSI
interface. For LAN connectivity, a TPE and AUI Ethernet connectors are
provided. For further integration the Epson ExpressStation comes with a
built-in PS/2 style mouse and keyboard port, two serial and one parallel
ports, VGA video port along with a PS/2 style feature connector, and a
floppy disk controller.
Q3. What is the target market for this computer?
A.
It is targeted as a network business workstation and CAD/CAM application
station, and to be used in office automation applications requiring multi-
function client systems, and as a high performance integrated PC
platform.

Q4.
What levels of security are provided with the Epson ExpressStation?
A.
There are several levels of security to insure that users do not change the
configuration of the Epson ExpressStation.
- J3 can be jumped on 2-4 to write protect the diskette drive to prevent
the downloading of software onto a diskette.
- J5 can be jumped on 4-6 to write protect the FLASH BIOS memory to
prevent alteration of it’s data.
- J21 can be jumped on 3-5 to disable the use of the BIOS SETUP
program so unauthorized users cannot change the settings you have
chosen.
- J21 can also be jumped on 4-6 to retain the power on password that
can be set in setup.
Physically the case can be locked by installing a padlock on the lock
box.
CPU
Q5.
A.
Q6.
A.
What are the microprocessors being offered for the Epson
ExpressStation?
The Epson ExpressStation supports all of the i486 CPU functionality. The
Epson ExpressStation will be offered with either a 25 MHZ i486sx
microprocessor or a 33 MHZ i486dx microprocessor. Common features of
the two different CPU’s include backward compatibility with the 8086,
80286, and 80386 CPUS, burst mode bus cycles, and an on chip 8kb
cache. The cache can be disabled via either the software or hardware.
The i486DX CPU contains an on-chip numeric coprocessor to increase the
speed of floating point operations. This processor is backward compatible
with the 387DX and 387SX math coprocessors and complies to
ANSI/IEEE standard 754-1985.
What processor upgrade sockets are available in this computer?
If the customer bought the 486sx/25 mhz. version of the computer, the
Epson ExpressStation can be upgraded by installing an i487sx component
in the socket. This improves system performance by adding a numeric
coprocessor to speed floating point calculations. Please note the
ExpressStation does not support the Weitek math co-processor. There is
no upgrade path at the current time for i486DX based systems.

PSB No: S-0147
Page: 3 of 9
Q7. What is the external cache memory option?
A. In addition to the i486’s internal cache, the ExpressStation provides a
socket for an optional 64 KB or 128 KB external cache, the Intel 485
TurboCache module. Please note that the external 128 KB cache module
comes standard on the i486DX/33 mhz. computer.
BIOS
Q8.
A.
Q9.
A.
What BIOS comes with the computer?
The BIOS is stored in two Intel FLASH EEPROM devices. It uses the
Phoenix Technologies 80486 ROM BIOS PLUS Version 1.00 04.SI. In
addition to the Phoenix Bios, the flash memory also contains the setup
utility, POST, video BIOS, SCSI BIOS, Ethernet address, EISA
configuration memory, EISA board ID, a 4 kb user definable region and
update recovery code. It also supports system BIOS shadowing allowing
the BIOS to execute from 32-bit on board write-protected DRAM instead of
the slower 8-bit FLASH devices.
How is setup accessed and what information is contained in setup?
To access setup, press F1 after POST completes the memory test but
before the system boots up. There are four pages of setup information.

EISA CONFIGURATION
Q10. What is the EISA configuration utility and what is contained in it?
A.
The EISA configuration utility allows you to configure your computer when
you have installed the following option cards:
- any EISA add-in boards
-
if you want to change the default SCSI or LAN interrupt levels.
- if you are installing any ISA cards that came with configuration files
(CFG).
You would use the program to do the following:
- learn about the configuration process
M
set the date and time
- copy the configuration ( CFG ) files for any option cards you install
- configure the system board and any option cards
- create one or more System Configuration Information Files ( SCI )
- access other system utilities - such as password, CPU speed, and
cache utilities
Q11. When do I run it?
A. You would run the utility when you first receive your computer and you
may need to run it later if you add or remove options, such as memory,
disk drives, or option cards.

PSB No: S-0147
Page: 7 of 9
Q12. Where is the information stored?
A.
It is saved in the computer’s FLASH memory and a file called
SYSTEM.SCI. Once you configure your computer with this utility, you
should not use the BIOS SETUP program. Always use the System
Configuration to configure your computer. The first time you configure
your computer, you must run the program from the Reference Diskette
and it is best to always run it from there. You can create an alternate SCI
file. Please refer to the Software Guide for details.
VIDEO
Q13. What type of video is included?
A. The VGA controller is a WD90C30 graphics controller. There is 1MB of
video RAM that comes standard. The last 512K of this 1 MB of video RAM
is socketed. This controller supports the following resolutions up to 1024
x 768 x 256 colors interlaced and non-interlaced. The 800 x 600 and
1024 x 768 refresh rates are controlled through setup. Please refer to your
monitor manual for the proper refresh rate.
In addition, there are two diskettes included which feature drivers for many
popular software programs and video utilities. Some of the drivers
included are Framework II, Gem 3.0 and 3.1, Lotus 1-2-3 Rel.
2.0, 2.01, 2.2/Lotus Symphony Rel. 1.1, 1.2, 2.0, Ventura Publisher 1.1 &
2.0, Windows 3.0, WordPerfect 5.0 & 5.1, AutoShade v1.x, Autocad
R9/R10 & release 11, Cadvance, Generic CADD, P-Cad, Versacad v5.3 &

MEMORY
Q14. What is the standard memory configuration and maximum amount of
memory that can be used in the system?
A. The ExpressStation comes with one 4 MB. SIMM installed on the main
system board. You can install additional SlMMs to increase your
computer’s memory to 32MB. You can install one, two, or four SIMMs,
you cannot install three SIMMs. There is a total of four SIMM sockets on
the motherboard.
The Epson ExpressStation can accept 1 MB, 2 MB, 4 MB, and 8 MB
SlMMs up to 32 MB (when 8 MB SlMMs are available); SlMMs must be
80ns or faster, 36-bit, 72-pin, gold leaded, fast page mode type.

What factory drive configurations are offered with the ExpressStation?
The Epson ExpressStation comes in four configurations. All four
configurations come with a 1.44MB floppy drive. The 486SX/25 and the
486DX/33 models can be sold without a hard drive. The 486SX/25
computer has a option to be shipped with a Quantum LPS120AT (120MB)
IDE hard drive. The 486DX/33 computer has an option to be shipped with
a Maxtor 340MB SCSI drive.
When would I use the SCSI drivers?
There are several instances that you would want to use the drivers. Some
of the most common uses are as follows:
The SCSI drivers should be installed if you will be using Windows or DOS
and an expanded memory manager such as EMM386.EXE or QEMM386.
The system has more than two hard disk drives.
If you have installed a removable hard disk drive, such as the Syquest
model SQ555, or you have installed a SCSI tape drive, CD-ROM, or other
non-disk SCSI device.
If you use programs such as a laser scanner driver that accesses the
SCSI BIOS via the CAM interface.

H If you will load your operating system from a NON-SCSI disk drive but will
also access the SCSI devices controlled by the built in SCSI controller.
For more comprehensive information, please refer to the Software Guide and
the readme.txt file found on the SCSI/LAN drivers for DOS diskette.

Q20.
A.
Can I use both the SCSI and IDE interface at the same time?
With the appropriate SCSI drivers, an external SCSI hard drive can be
attached to the Epson Expressstation simultaneously with an internal IDE
drive.
When should the SCSI terminator be attached to the external SCSI port?
Whenever the SCSI drive is used, there should be a SCSI terminator only
at the beginning and end of the chain. The SCSI controller board contains
the beginning terminator. The SCSI terminator should be attached to the
end of the chain. If the customer ordered the computer with an internal
SCSI drive installed, it should already be terminated. Should you wish to
add an external SCSI device, remove the terminator from the drive and
attach a SCSI terminator to the end of the external device.
After going into setup using the F1 option in POST everything looks fine
until hitting F2 to display the system information. At that point some
garbage appeared on the screen. What can be done?
Try running setup off the System Configuration diskette. This seems to
clear that screen.
Setup ( Eisa Configuration Utility ) was run off the System Configuration
Diskette but changes were not saved and now the system won’t boot - is
there any way to correct this?
Try clearing CMOS by moving the jumper on the J21 block from 11-13 to
9-11. After you move the jumper turn on the computer and see if it will
boot. Once it boots, you can power down and change back the jumper to
11-13 to retain CMOS settings and then run setup to set CMOS.
