Note: The Epson Monochrome Monitor (Model MBM-2095-E) was discontinued
as a sales item as of June 1991. However, it is available as a warranty
exchange item from the parts department.
2. Compatibility:
Monochrome Display Adapters are compatible on the Epson Equity 386/33
Plus system.
Pre-configuring system C-MOS is required. Refer to page 2 of
this document for details.
3. Display Symptoms & Causes:
System CMOS must be pre-set to successfully install a Monochrome video
sub-system. The system will not sync properly after a Monochrome adapter
and display are installed. A common complaint at that point is that the system
is dead (no boot activity or keyboard response).

PSB No: S-0162
Page: 2 of 3
Hardware CMOS settings are incorporated into the BIOS ROM. VGA is the
hardware default setting for video support. If a monochrome display adapter
and monitor are installed and the system booted, the monochrome monitor will
not synchronize properly because VGA BIOS calls are still being refreshed.
Two possible indications can occur at this point:
a) constant diagonal raster [loss of Horizontal Sync]
b) randomly lite pixel characters on display, no raster update visible.
The system is operational even though display is garbled or not apparent. The
system has encountered a conflict between CMOS settings and the hardware
that is sensed by the system. Hitting the ‘F1’ key will allow the boot process to
continue and the system will load the operating system even though no display
may be present.
4. Changing CMOS for Monochrome Video Support
A.) Attach a VGA monitor to the external VGA port on the rear of the system.
B.) Boot the system. During boot process hit the delete, <Del>, key to enter
the CMOS setup program.
C.) A ‘Start operating system/Run Setup’ screen will be displayed. Hit the
down-arrow key to highlight ‘Run SETUP’.
D.) Hit the ‘Enter’ key to start ‘SETUP’.
E.) Hit the down-arrow key to the ‘Primary Display’ option. ‘VGA or EGA
setting is currently highlighted.
F.) Hit the PgUp/PgDn key twice to set ‘Monochrome’.
G.) Hit the Escape key, <Esc>, and a message ‘Save SETUP configuration
(Y/N)?’ is displayed. Enter the letter Y and hit enter to continue.
H.) The system will reboot and go through ‘POST’. An error message will be
displayed:
CMOS display type mismatch
Press <F1> to run SETUP or RESUME.
I.) Press the <F1> key to continue
J.) The ‘Start operating system/Run Setup’ screen will be displayed. ‘Start
operating system’ is highlighted. Hit the ‘enter’ key to start the operating
system and load DOS.

6. Changing Hardware jumpers for Monochrome Video Support.
A.) Power down the system and change the hardware jumpers for
monochrome support.
J1 Onboard VGA video port: J4 Color/Monochrome Monitor Used:
(3” from rear of main pcb on RtSide)
(4.5” from rear of Main PCB on RtSide)
(1” from the DC power connector)
A setting Video port enabled A setting Color monitor attached
B setting Video port disabled B setting Monochrome Monitor attached
B.) Configure the video adapter card appropriately for the monitor, in particular
the Horizontal frequency output from the video card being used. In our
test, the default Horizontal output frequency from the MDA card had to be
changed from 31.5KHz to 18.44KHz. When the adapter was installed
using the factory defaults, 31.5Khz, upon powering-up the system item ‘b’
under display symptoms mentioned above was encountered.
C.) Install the video adapter in an available expansion slot. Attach the
monochrome monitor to the MDA’s video port.
D.) Power up the system and then the monochrome display. The system will
reboot and load to DOS. Epson MS-DOS, Microsoft Windows 3.1 and
Lotus 3.1 were tested without any operation or video errors.
7. General Installation Tip:
During the test, a configuration error was noted when the Color/Monochrome
jumper, (J4), was not moved to the Monochrome setting. Upon boot, the
monitor displayed four legible ‘DOS’ prompts in 4 equally spaced quadrants of
the screen. Setting the J4 jumper to the Monochrome setting corrected the
problem and the system functioned under general testing criteria (i.e. DOS,
Windows applications, Lotus etc.)
The setting of the system jumpers is of critical importance for a successful
Monochrome video sub-system installation.

4. Possible display symptoms and causes.
System CMOS and video jumpers must be set appropriately to successfully
install any video adapter. The system may not sync properly after an adapter
and display are installed. A common symptom is that the system appears to
be dead (no boot activity or keyboard response).
Hardware CMOS settings are incorporated into the BIOS ROM. Color VGA is
the hardware default setting for video support. If a display adapter and monitor
are installed and the system booted, the monitor may not synchronize properly
because VGA BIOS calls are still being refreshed. Two possible indications
can occur at this point:
a) constant diagonal raster [loss of Horizontal Sync]
b) random pixel characters on display, no raster update visible.
The system is operational even though the display may be garbled or not
apparent. The system has encountered a conflict between CMOS settings and
the hardware that is sensed by the system. Hitting the ‘F1’ key will allow the
boot process to continue and the system will load the operating system even
though no video display may be present.
5. Examining CMOS for Third Party video support (video card on bus);
A.) Attach a Color VGA monitor to the external VGA port on the rear of the
system.
B.) Boot the system. During boot process hit the delete, <Del>, key to enter
the CMOS setup program.
C.) A ‘Start operating system/Run Setup’ screen will be displayed. Hit the
down-arrow key to highlight ‘Run SETUP’.
D.) Hit the ‘enter’ key to start ‘setup’.
E.) Hit the down-arrow key to the ‘Primary display’ option. ‘VGA or EGA’
setting is currently highlighted.
F.) Verify that ‘VGA or EGA’ is set and DO NOT alter the setting.
G.) Hit the Escape key, <Esc>, and a message ‘Save SETUP configuration
(Y/N)?’ is displayed. Enter the letter Y and hit enter to continue.
H.) The system will reboot and go through POST and load DOS.

PSB No: S-0157

6. Changing hardware jumpers for Third-Party video support;
A.) Power down the system and change the hardware jumpers to disable the
embedded VGA adapter port on the system board. (Settings listed bold
are used in this configuration.)
J1 Onboard VGA video port:
(3” from rear of main PCB on RtSide) J4 Color/Monochrome Monitor
(4.5” from rear of main PCB on
RtSide, 1" from the DC power
connector)
A setting, Video port enabled
B setting, Video port disabled A setting, Color monitor attached
B setting, Monochrome Monitor
attached
B.) Install the video adapter in an available 16 bit expansion slot. Attach a
monitor to the Super Dual VGA adapter, lower port (primary video port).
Attach a secondary monitor to the upper port on the video card (secondary
video port).
C.) Power up the system and then both displays. The system will reboot and
load DOS. The secondary monitor will display the bios revision of the
video adapter until a Windows session is started. After ending a Windows
session, the second monitor will only display a blinking cursor in the upper
left corner of the display. This is normal operation of the display adapter.
Dual monitor support is only active by using the appropriate video driver
and application. Epson MS-DOS, MS-Windows 3.1 were tested without
any operation or video errors.
7. Video adapter hardware configuration:
A.) Factory Defaults were used throughout the testing process. There is one
dip switch block and 5 jumpers on the video card. Jumpers J3, J4, J5 can
be altered, jumpers J1 and J2 are for EPROM size and should not be
changed. Switch bank 1 (SW1) has 4 rocker setting for on or off. The
defaults are:
1=off 2=on 3=on 4=on.
Switches 1 and 2 sets the board to primary video base I/O address of
34C(hex) and secondary video base I/O address of 348(hex). Switches 3
and 4 sets the video adapter I.D. to zero (binary 00). This is done if
multiple Super Dual video adapters are installed. This information can be
found on page 4 and 5 of the Super Dual VGA Operations Manual.

PSB No: S-0157

8. Dual VGA video driver installation:
A.) A Super Dual VGA Utility Disk is supplied with the video adapter. The root
directory contains a READ-ME file with general information on installing
the various video drivers. The root directory contains a WINDOWS_DOC
file with specific information on how to install the Windows Video drivers.
B.) The file recommends installing the video drivers from the DOS prompt and
not from the Windows dos prompt. From the Windows subdirectory, run
SETUP. Select ‘display’, scroll down the list of available video drivers and
highlight “other display”. If necessary, specify the drive letter and path i.e.
(a:\w31). Select the desired resolution and press return. The process will
transfer various files from the floppy to the C:\WINDOWS\SYSTEM
subdirectory. You may be prompted for several of the Windows diskettes.
Please have them available.
C.) Upon completion of the file transfers, restart Windows. Verify that the
desired video driver is being utilized. Double-click on the Main Program
Group, double-click on the Windows Setup program item. The current
hardware settings are displayed on the Windows Setup screen. At the
display setting, the previously selected Super Dual VGA driver is being
utilized. For this session, the following driver was used:
Super Dual VGA H2V1 640x480x256.
D.) Using two monitors, Windows usage across both displays was confirmed.
No video anomalies or errors were encountered.
9. Resolutions tested.
A.) Super Dual VGA H2V1 640x480x16 Ok
B.) Super Dual VGA H2V1 800x600x16 Ok
C.) Super Dual VGA H2V1 1024x768x16 Ok
D.) Super Dual VGA H2V1 640x480x256 Ok
E.) Super Dual VGA H2V1 800x600x256 Ok
10. General Installation Tip:
The setting of the system jumpers is of critical importance for successful
Third-Party’ video support.

7. Extracting/Exploding the Video Driver suggestions:
Down-load the
ET4DRV.EXE to your local hard disk drive, a 1.2Mb or 1.44Mb diskette. The driver
files expand-out to approximately 643,174 bytes of data space. Run the file
ET4DRV.EXE and the
files will extract themselves into the disk/current-directory. lf the current directory has data on it,
copying the necessary files to another diskette may become tedious (Housekeeping tip).
Recommendation: Transfer the ET4DRV.EXE onto another diskette and write-protect it. Keep it as
a Master diskette for duplication purposes. Delete the driver file from the exploded diskette, write-
protect it and use it for duplication purposes.
8. General Installation Tips:
I installed the new driver files from within Windows. From Program Manager go to File and select
Bun... and in the Command Line: box type in setup. This will bring up the Windows Setup
program group. Select Options and then select change System Settings.. the Change System
Settings program group is displayed with the current values.
At Display click on the down arrow
symbol at the end of display mode currently highlighted in black. A list of video drivers and modes
are displayed. Scroll down and highlight
Other display (Requires disk from OEM)... Click on OK
button. A message is displayed to insert the OEM diskette into drive A:\. Insert the diskette with
the uncompressed video drivers into drive a:\. Click on OK button.
Select the desired video driver you wish to install, such as:
ET4000 800x600 256 col. (Large fonts)
Click on OK button. The new driver is displayed in the Display parameter in the Change System
Settings program group. Click on OK button. The Change System Settings program group then asks
you if you want to install a new driver. Select New and have Window 3.1 diskettes 1 through 3
ready for updating the fonts needed for the new driver.
The system will ask you at various points to install the diskettes as needed. The system transfers
the various fonts onto the hard disk drive. The system asks you to install the ET4000 Windows 3.1
driver disk. Install the diskette and click the OK button. The driver files are loaded on to the hard
disk drive.
The Exit Windows Setup program group appears at this point. You are asked to either Restart
Windows or Continue.
Warning: the system alerts you not to warm boot ( CTRL+ALT+DEL )
or loss of data will occur.
Restart Windows and the new driver and fonts will be activated.

Product Support Bulletin
Subject: Equity 386/33 PLUS Incompatibilities
Date: 6/5/92 PSB No: S-0140
Page(s): 1 of 2Originator: JAM, MT, MD
The purpose of this bulletin is to provide information on known incompatibilities of
the Equity 386/33 PLUS at the time of product introduction.
1.
IBM 5251/11 Emulation Adapter is not compatible. Variance #la: Loss
of video output upon powering on the system at cold-boot. The Hard
disk is accessed during the boot process but no video display can be
seen. The Testing Lab experienced this variance previously using the
5251 card for 8-bit slots ( DET92X0693 Rev B ). The 5251 card for 16-
bit slots ( EC#A131192B ) completely passed. Variance #lb: Random
video characters are displayed after entering DIR followed by CLS. The
anomaly manifests itself only if the commands have been executed in
that order.
2. AST 5251/11 Emulation Adapter is not compatible. Variance #2: Upon
rebooting the system, foreground and background colors are nearly the
same. This makes distinguishing characters difficult. Other operations
function normally.
3.
DTC 6180 ESDI Hard Disk Controller is not compatible. Variance #3:
Low-Level formatting of ESDI does not complete successfully and
returns a fatal error message.
STATUS: Resolutions to these Variances are being researched by EPI.
WORK AROUNDS:
1.
Variance #la: Pressing the RESET button caused the 5251 adapter to
work properly. ALL EMULATION TESTING THEN PASSED!
Variance #lb: No workaround was found by the Testing Lab.
2.
Variance #2: Two workarounds for this are: (1) Disable the on-board
video port and use a VGA adapter in a bus slot or (2) configuring
SETUP to COLOR rather than VGA resolves the screen problem.
3.
Variance #3: Low-level formatting the drive on another system and
reinstalling it in the Equity 386/33 Plus is an alternative. The system
functioned normally thereafter.

PSB No: S-0140

Test Labs Results:
1.
The Epson 386/33 Plus successfully executed
142 ( 98% ) out of 145 tests without variance.
2. The Equity 386/33 Plus has been extensively tested by an outside Third
Party Testing Lab. Out of a “TEST SUITE" of 145 Hardware and
Software combinations, these are the only outstanding variances.
