800x600 Graphic and 132-Column Text Modes
1. To install extended support for Lotus 1-2-3, run the install
program on the Basic VGA driver diskette as explained in E.2
(page 20). Choose the Lotus 1-23 drivers when prompted.
2. Run the INSTALL program supplied with Lotus 1-2-3.
3. From the Main Menu, select ADVANCED OPTIONS and then ADD NEW
DRIVERS TO LIBRARY. Once complete, select MODIFY CURRENT DRIVER
SET, and choose GRAPH DISPLAY or TEXT DISPLAY as desired.
4. A selection for Basic VGA 800x600 will appear in the GRAPH
DISPLAY selection list. You may select any combination of
standard VGA and Basic VGA drivers for your installation.
5. When you are satisfied with your choices, return to the
previous menu and select SAVE CHANGES. Now, exit the install
program and run 1-2-3 in the normal way.
If you wish to save space on your hard disk, only copy the
resolutions that you need:
BVGAGR.DRV Basic VGA 800x600 Toggle V1.0 Graphics
TC132X25.DRV Basic VGA 132x25 Color Text
TC132X43.DRV Basic VGA 132x43 Color Text
TM132X25.DRV Basic VGA 132x25 Mono Text
TM132X43.DRV Basic VGA 132x43 Color Text
Once you have selected your new driver(s) and tested them, you
may delete the *.DRV file(s) from your 123 directory.
*********************************
Ventura 2.0: 800x600 Graphics
*********************************
1. Install Ventura Publisher, using the standard instructions and
utility programs supplied with the product. During installation,
choose a standard VGA 800x600 option from the list of screen
drivers.
2. Run the install program on the Basic VGA driver diskette as
explained in E.2 (page 20). This will copy the SDBVGA86.VGA file
to the \VENTURA subdirectory on your hard disk drive.
3. The name of the current screen driver is found in the last
line of VPPROF.BAT. The line should look something like this:
DRVMRGR VPPROF %1 /S=SDFVGAH5.VGA /M=30
Replace the driver name (that portion of the above line after
"S=" and before "/M=30") with SDBVGA86.VGA. In this case, the
exact change would be to replace SDFVGAH5.VGA with SDBVGA86.VGA.
The file name you replace will vary depending on what video card
was previously specified. When Ventura is run in the normal way,
the 800x600 16-color graphics mode of the Basic VGA will be used.
*************************
GEM: 800x600 Graphics
*************************
1. To use GEM by itself, install it using the utilities supplied
with the GEM DESKTOP package.
2. Run the install program on the Basic VGA driver diskette as
explained in E.2 (page 20). This will copy the SDBVGA86.VGA file
to the \GEMAPPS\GEMSYS subdirectory on your hard disk drive.
3. Delete any other screen drivers with the .VGA extension from
the GEMAPPS\GEMSYS subdirectory. When GEM is run in the normal
way, the 800x600 16-color graphics mode of the Basic VGA will be
used.
*************************
WordPerfect 5.1 Driver
*************************
800x600 Graphics and 132-Column Text
1. Run the install program on the Basic VGA driver diskette as
explained in E.2 (page 20). Choose the WordPerfect 5.1 driver
when prompted.
2. Start WordPerfect in the normal way:
WP [ENTER]
Select the Setup option ([SHIFT F1])
Select DISPLAY, then select either GRAPHICS SCREEN TYPE or TEXT
SCREEN TYPE. Text Screen Type selects the driver for normal
editing mode and Graphics Screen Type selects the driver for
graphics editing and the document preview mode.
3. For each category, the selection list includes options for the
Basic VGA card as well as other screen types. Choose a
combination of drivers which will provide the desired modes of
operation. You can select any combination of VGA and Basic VGA
drivers.
4. When you are finished making your selections, press Exit [F7]
and the selection will be saved. If you have changed the Text
Screen Type, the screen will immediately reflect the new mode
selected. The new graphics mode will be used the next time the
print preview operation is invoked or when graphics file editing
is invoked. See your WordPerfect manual for details.

VGA006 UTILITY NOTES
*******************************
Included with this diskette are three utility programs for the Basic VGA. These
programs are RAMBIOS.COM, ETM.EXE and VDIAG.EXE. They are located in the
UTILITY subdirectory.
RAMBIOS.COM
RAMBIOS.COM is a terminate and stay resident (TSR) utility that
can, under certain conditions, speed up the text display. The
best performance increase that can be expected is about 25%.
The best conditions to use RAMBIOS is when the application is
text-based and there is a lot of information to be displayed.
However, RAMBIOS takes up nearly 30k of system memory. Depending
on your system and applications, this can be an excessive amount.
If you use Windows, Gem, Smalltalk or any of the many other
graphical user interfaces, DO NOT USE THIS UTILITY. It will do
absolutely nothing to increase performance, and still take up
that 30k of memory.
The decision to use or not use RAMBIOS is dependent on the system
that the Basic VGA is installed in, what types of application
programs are used, and whether or not the user is patient enough
to perform several trial-and-error installations of RAMBIOS to
determine usability and performance gain.
TO USE RAMBIOS, simply change directories to the UTILITY sub-
directory (type CD UTILITY <ENTER>), and type RAMBIOS <ENTER>.
The screen will momentarily go blank, and then a message
will appear which identifies the version. After the program is
run, it will return you to the DOS prompt. This effect is similar
in appearance to re-booting or resetting your system, BUT THIS DOES
NOT HAPPEN. Any other TSR programs, such as ramdrives, will still
be functional.
ETM.COM
ETM stands for Extended Text Mode utility.This program allows the user
to change the display mode of the Basic VGA. It will change to these
options:
BVGA EXTENDED TEXT MODE UTILITY - ETM.EXE - Version 1.00
Options:
132x25
132x28
132x43
80x50
80x28
40x50
80x25
40x25
? (displays the option list)
In some cases, older software may be able to address a high resolution
text mode screen. For example, WordPerfect 4.1 can be configured
to use a 132 column screen via setup parameters. To do this,
type:
ETM 132x25<ENTER> ;this changes the display mode
WP /S<ENTER> ;enter wp in setup mode
At the setup menu, select SPECIFY SCREEN SIZE. Edit the NUMBER
OF COLUMNS field, by typing 132. Exit the setup menu. You will
now enter WordPerfect in 132 column mode.
To use the full width of the screen, change the margin size (refer
to your WordPerfect manual to do this).
Be sure to reset your screen to 80x25 after leaving WordPerfect
by typing
ETM 80x25<ENTER>
Other applications may also have this ability, refer to your users
manual for the specific details.
VDIAG.EXE
This program is a test program specifically for the Basic VGA by
Boca. It performs a variety of tests, after which it will allow
the user to select various resolutions to adjust the display monitor.
To use VDIAG type:
VDIAG<ENTER>
The VDIAG.EXE program is provided so that the user may test the
functionality of the Basic VGA by BOCA board. This program provides
a step by step diagnostics procedure for testing the board.

Each color is identified by text.
Problems
========
If the program finds a problem, review your installation of
the VGA by BOCA board. Make sure the board is firmly seated
in its connector and the cables are properly attached.
Run the Diagnostics program again. If you are still having
problems, call the Boca Research Technical Support Department.
