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.

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.

PSB No: S-0162

(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.

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.

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

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

Page: 4 of 4

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

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.
