large, easy-to-read legends to allow for the
easy configuring of the product. This
installation manual contains detailed
instructions. Most included software has automatic installation
programs to place the software correctly onto your computer.
However, as all computers are configured differently, you may
be required to perform some basic DOS or Windows tasks. If
you are not familiar with basic DOS commands such as DIR,
CD, or EDIT, you should check your DOS manual, or seek
assistance from you local computer dealer to install the
product.
How to get Technical Assistance
The dealer that you purchased this
product or your computer from is the first
place you should go for technical
assistance. The dealer is usually the most
qualified source of help, and is most
familiar with your system and how this product should be
installed. Many dealers have customer service and technical
support programs, with varying levels of support offered,
depending on your needs and computer knowledge. Please
contact the dealer first whenever a problem occurs.
If your Dealer Can’t Assist you
If you can’t get assistance from your dealer, the manufacturer
provides varying levels of technical assistance as summarized
on the following page.

Section Two: Compatibility & Requirements
Please examine the SuperX VGA board and driver diskette to see
if there is any damage which may have occurred during
shipment. If damage exists or if anything appears to be missing,
please contact the retailer from whom the SuperX VGA was
purchased.
2.1 Installation Requirements
This user manual is designed to answer questions you might
have concerning the installation and use of the SuperX VGA, as
well as provide descriptions of legitimate system configurations.
Please take a little time to read through this manual before
installing your SuperX VGA.
2.2 Monitor Compatibility
The SuperX VGA board is compatible with VGA Color and
monochrome Analog monitors. TTL monochrome monitors with
9-pin connectors are NOT compatible with the SuperX VGA. It is
also compatible with Multiple Frequency Monitors, provided the
proper 15-pin cable adapter is used with the monitor and the
monitor is set to analog.
IMPORTANT: The SuperX VGA uses the same 15-pin (DB15)
cable available from monitor manufacturers to interface with
the IBM PS/2 computers. Using an incorrect cable may result in
damage to the monitor and/or adapter. Contact the monitor
manufacturer for proper cabling and pin-outs if you have
questions.

9
2.3 System Compatibility
Most clones are compatible with the SuperX VGA. If you are
uncertain, refer to your system’s guide to operation or check with
the dealer or manufacturer of your computer. The SuperX VGA
board is compatible with the IBM Video Graphics Array and
Enhanced Graphics Adapter.
Most compatible systems support the IBM VGA or EGA
standard. If your computer supports the IBM Enhanced Graphics
Adapter, then the SuperX VGA board will work in your system.
Some systems may require a ROM BIOS upgrade to support
VGA display. Consult your computer dealer regarding
availability of such an upgrade for your particular system.
NOTE: Drivers are not necessary for normal VGA operation.
Drivers are included on a 1.44MB 3.5-inch high-density diskette
only. You may download drivers released after the printing of this
manual from our BBS 24 hours a day at [phone] (N, 8, 1).
However, if you decide to use the drivers, run the utilities as
described in Section Four.

Section Three: Physical Installation
Installation of the SuperX VGA board is simple and quick for the
expert and novice alike. The following instructions assume an
AT-style or compatible machine. Obviously, locations and types
of screws as well as type of case cover will vary based on your
particular system. Refer to your computer system documentation
for additional assistance.
1. Turn the power switch to the OFF position.
2. Remove the power cord from the back of the computer.
3. Unplug the keyboard cable found in the lower middle of the
computer’s rear panel.
4. Use a small screwdriver to remove the screws that attach the
computer’s cover to the rear panel.
5. Carefully slide the cover forward—away from the rear panel.
Be careful not to let the cover catch on internal cables to the
disk drive and power supply.
The SuperX VGA board must be installed in any
available 16-bit slot in your system.Adapter card
connector slots normally reside in the rear of the system
board adjacent to the power supply. There are usually
anywhere from five to eight edge connectors, depending
on the model of your system.
Physical Installation

12

6. Select any available 16-bit expansion slot and remove the screw
and the metal plate that covers
the external access to the slot
you have selected.
7. Insert the SuperX VGA board in
the slot that you have selected,
so that the edge connector on
the bottom rear of the board
mates with the socket on the
motherboard. Press down
firmly on the board. Secure the
board with the screw which
you just removed.
8. Some older motherboards
require that switches or jumpers be set for VGA (EGA on still
older machines). With newer systems, this is done through the
system CMOS setup. Refer to your system documentation for
instructions on either jumper settings or running CMOS setup.

13
9. Slide the computer cover back over the chassis taking care not
to let it catch on the disk drive or power cables. Once the cover
is in place, replace all the screws that you removed earlier. Re-
attach all cables and power cords to their original positions.
Attach the appropriate monitor cable to the SuperX VGA.

Section Four: Preparing Your Monitor
The CLMODE utility allows you to define the type of monitor
attached and preview the video modes supported by your
monitor. CLMODE is installed by running INSTALL from the
driver diskette and choosing “SUPERX VGA UTILITIES”, the
first selection on the menu. After installation, type the command
CLMODE from the subdirectory in which CLMODE was
installed (e.g., C:\CLUTIL\CLMODE). Refer to section 5.1 on
“Installing Display Drivers” for more information.
4.1 Choosing the Attached Monitor Type
Selecting the proper monitor type will allow the Boca SuperX
VGA to display the highest quality output that it is capable of
with the attached monitor. The monitor type determines what
video modes will be available to your system. It will also
determine the vertical refresh rates available to your system.
Generally, the higher the refresh rate, the better the screen will
look.

Preparing Your Monitor
Select Monitor Type to display the Monitor Type Setup window.
The current monitor type and refresh rate will be highlighted
initially. Use the keyboard or the mouse to choose the type of
monitor attached. Press the OK button to set the new monitor
type. Press the CANCEL button to discard any changes. Press
HELP for an explanation of the monitor types and VGA refresh
rates. For example, if you choose monitor type 1, CLMODE will
restrict the maximum non-interlaced resolutions to 640x480 at
60Hz and the maximum interlaced resolutions to 1024x768 at
87hz, only. See sample screen below:
If you choose monitor type 6, CLMODE allows the maximum
non-interlaced resolution to be 1024x768 at 70Hz. See sample
screen which follows:

On some systems the monitor type is remembered from one
session to the next. To test this, select a monitor type and exit the
CLMODE program. Turn the computer off for approximately ten
seconds.
After rebooting the computer, run CLMODE and verify whether
or not the monitor you selected is still enabled. If it is, it should
never be necessary to set the monitor type again during normal
operation. If the monitor type was not kept, then it will be
necessary for CLMODE to be added to your AUTOEXEC.BAT.
IMPORTANT: Never choose a selection that your
monitor does not support. See the chart on page 20
for some examples.

contains one or more menu items. The underlined letter of a
menu item specifies the hot keys combination for that item. For
example, pressing the [T] key selects the Monitor option. Note
that a mouse driver must first be installed prior to running the
CLMODE utility in order to use the mouse pointer for menu
selection.
4.3 Previewing the Video Mode
Select Video Modes from the main window. The Video Modes
Preview window displays all the modes supported according to
the monitor type selected and the video memory present. Use the
