        =================================================================

        This directory contains drivers for use on AutoCAD version  2.52,
        2.62,  and  Release 9 and 10. The directory  should  contain  the
        following files:

                 o ACAD54B.EXE   - 800x600 (16-color) driver
                 o ACAD61B.EXE   - 640x400 (256-color) driver
                 o ACAD62B.EXE   - 640x480 (256-color) driver - requires
                                   512k memory
                 o ACAD63B.EXE   - 800x600 (256-color) driver - requires
                                   512k memory
                 o ACAD65B.EXE   - 1024x768 (16-color) driver - requires
                                   512k memory
                 o ACAD67B.EXE   - 1024x768 (4-color) driver
                 o ACADDRV.EXE   - Driver installation program. This
                                   program is started by the main program
                                   VDRIVER.EXE.
                 o README.ACA    - This file.

        -----------------------------------------------------------------

        The setup procedure is as follows:

                 1.  Install AutoCAD onto your hard disk.

                 2.  Run the VDRIVER.EXE and follow the instructions given
                     by the program.

                 3.  Run AACAD.BAT.  (created by VDRIVER)

                 4.  Configure AutoCAD to load the ADI driver the first
                     time only.  See CONFIGURING AUTOCAD.

        ----------------------------------------------------------------

                             CONFIGURING AUTOCAD

        The first time you use AutoCAD with the ADI drivers, you need  to
        configure AutoCAD for the ADI display.

        1. Select  CONFIGURE  AUTOCAD  from the AutoCAD  main  menu.  (If
           AutoCAD  was not previously configured, you are  automatically
           put into the configuration menu when you start AutoCAD).

        2. Select CONFIGURE VIDEO DISPLAY from the configuration menu.
           Select the ADI display from the list of video displays.

           The  ADI  drivers support ADI display version up to  V4.0.  If
           your  AutoCAD has more than 1 ADI display version, choose  the
           highest one.

        3. The ADI display uses interrupt 7A as default. You can accept
           it by pressing ENTER at the prompt for display option configu-
           ration:

                   Hexadecimal interrupt code (INT 0XXh) <7A>:

           If  your system requires a different interrupt code,  type  in
           the corresponding interrupt in hexadecimal number.

        4. Select the appropriate options and save the new configuration.
           Do  not  select a command prompt area if you  are  using  dual
           monitors.  (See DUAL DISPLAY ADAPTER CONFIGURATION)

           For  more information on configuring AutoCAD, consult  AutoCAD
           manual.

        -----------------------------------------------------------------

                          LOADING THE ADI DRIVERS

        The ADI drivers differ from the drivers distributed with  AutoCAD
        in  that  they  must be loaded BEFORE running  AutoCAD.  The  ADI
        drivers are "terminate and stay resident" programs.

        1. The ADI drivers have several options, which are  invoked  when
           the drivers are loaded.  The syntax is as follows:

                       ACADxxB [i] [d] [-yy] [256]

            where xx is the resolution mode (54, 65 ...etc.)

            It is not necessary to use any of the options and most  users
            will  find the default settings the best for their use.   The
            options can be entered in any order.  If no option is  speci-
            fied, the drivers will use the default settings.

        OPTIONS

            A. The 'i' select a gray background on the drawing area.  The
               default  is  black.  They are the only choices  for  back-
               ground.

            B. The 'd' selects dual display.  If your system is equipped
               with  an  additional monochrome text  cards,  this  option
               allows  you to put the drawing on a multisync monitor  and
               the  text  on  a monochrome  monitor.  (See  DUAL  DISPLAY
               ADAPTER CONFIGURATION)

            C. The 'yy' parameter specifies an alternate interrupt vector.
               The default interrupt is 7A.  If you are using a NOVELLE

               network or any other software that also uses interrupt 7A,
               we suggest that you use interrupt 7B.

               Do not experiment with this feature unless you are very
               familiar with IBM PC software standards as this may cause
               problems.

            D. The '256' parameter reassigns the 16-color patterns to the
               256-color  patterns.   This option is  used  for  16-color
               drivers  only.  To display the new color assignment,  look
               at the chroma sample drawing or select the chroma  command
               from the COLORS menu.

               CAUTION:  You will find that if you select this option and
               your drawing uses a color number higher than 9, the  color
               is  displayed differently because of the  reassignment  of
               colors.

        2. If you are not using the default settings for the ADI  driver,
           you need to modify the AACAD.BAT.  This batch file is  created
           by VDRIVER.  For example:

                         AADI -7B d

           will load the driver with interrupt 7B and dual display.

           Note: the interrupt you use for the ADI driver must match with
                 the one selected in step 3 of CONFIGURING AUTOCAD.  The
                 syntax described in step 1 allows you to load the ADI
                 driver without using the AACAD.BAT

        -----------------------------------------------------------------

                       DUAL DISPLAY ADAPTER CONFIGURATION

        Under IBM standards, Dual Display Adapter configurations are only
        fully  supported up to the EGA graphics standard.   Dual  display
        adapter configurations will work under VGA but are not  supported
        and have some idiosyncrasies.  Your VGA adapter follows both  the
        EGA and VGA dual display configuration guidelines, depending upon
        the hardware  compatibility selected with VSETUP.

        Dual Display - EGA Standard.

        To run EGA dual display, install both the VGA and the  monochrome
        adapter(or Hercules adapter in HALF configuration) in the system.
        Run the VSETUP utility and select EGA Dual display from the menu.
        You  must specify which adapter you wish to run as  primary  (the
        adapter which is active during the boot).  If you wish to run any
        Hi-resolution applications (e.g. GEM/3)  you must run the command
        VCONFIG VGA COLOR prior to running the application.


                                        
        Disk 2       README.ACA                           Page 4


        Dual Display - VGA Standard.

        In a dual adapter configuration, VGA adapters always boot as  the
        primary  display  (the  active display at boot  time).  Your  VGA
        adapter  follows  this  same  standard.   After  installing  both
        adapters  run  VSETUP and select VGA as the default  mode.   This
        will  cause the VGA card to always boot as the  primary  adapter.
        The high resolution capability of the VGA adapter will  automati-
        cally be available upon completion of the boot.

        Note: Prior to running AutoCad with dual display, you must always
        make the monochrome display the active display.

        If  you have dual adapters (VGA & Monochrome) and you do not  use
        the  dual display option, you must start AutoCAD from  the  color
        display.
        -----------------------------------------------------------------


                                 COLORS CODING

        The ADI drivers use the color coding described in the AutoCAD
        manual. The color coding is summarized as follows:

                0 - Black                 8 - Dark Gray
                1 - Red                   9 - Dark Red
