                   AUTOCAD ADI DRIVER PROGRAMS FOR
                    VGA/Ultra ADAPTER HIGH RESOLUTION

The following instructions are applicable to users of Autodesk Inc.'s
AutoCAD Releases 9 and 10, and the VGA/Ultra Adapter.

The enclosed VGA/Ultra Adapter ADI Driver contains an AutoCAD driver
program called VADIR40.EXE, which in turn is configured by a file
called VINST.EXE. The VADIR40.EXE program makes full use of the
800x600 and 1024x768 graphics modes of the VGA/Ultra Adapter. Your VGA
monitor must be capable of displaying this resolution in order to
utilize this driver program.

Be sure that your VGA monitor can display 800x600-and/or 1024x768-
pixel resolutions. Choosing a higher resolution than your monitor is
capable of displaying will bring about unsatisfactory results.

To configure VADIR40.EXE you must first run the VINST.EXE program. In
running this, you must answer several questions dealing with
Resolution, Configuration, and Screen Colors by entering a new value
or pressing RETURN to accept the default value displayed by each
question.

After all questions are answered in VINST.EXE, the program will
display a message declaring the AutoCAD ADI driver successfully
modified.

Note that there is an extensive list for determining the colors of the
various entities comprising the graphic screen. The setting of these
colors requires entering a color code number. The following is a
listing of color code numbers.

        0 Background                    4 Cyan
        1 Red                           5 Blue
        2 Yellow                        6 Magenta
        3 Green                         7 White
        8-15 intensified versions of codes 0-7.

After setting colors for all of the screen elements, your ADI driver
configuration is complete.

At this time, you should run VADIR40.EXE to load the configured
driver, before loading AutoCAD. If you wish to change any of the
screen element attributes, simply run VINST.EXE again to make changes
and run VADIR40.EXE again before loading AutoCAD. VADIR40.EXE should
always be run before loading AutoCAD in order to display in the
resolution, and with the screen attributes of your choice.

Running AutoCAD

After the ADI driver has been configured to your requirements and
VADIR40.EXE has been run, AutoCAD can then be loaded.

Using the AutoCAD documentation configure AutoCAD. Simplified
