DRIVER INSTALLATION FOR USE WITH AUTOCAD RELEASE 11, 12:

 1. Copy driver (RCP_S3.EXP) to a convenient location.
    The file INSTALL.EXE can be used to copy the
    driver by first logging onto the desired drive and
    directory  then typing
               A:\> install

    Then select INSTALL's \Autodesk ADI4.2 (Protected Mode) \ menu,
    press ENTER key and complete the installation.
    INSTALL will copy the appropriate files to your default directory.

 2. Set the environment variable  ACADDRV=\to point to the
    Aquila sub-directoryand load files into Aquila sub-directory as well.
     Example:
     ACAD 12     SET ACADDRV= C:\ACAD\ACTIX\;C:\ACAD\DRV\
     
     ACAD 11     SET DSPADI = C:\ACAD\ACTIX\RCP_S3.EXP
                 SET RCPADI = %DSPADI%
                 SET RDPADI = %DSPADI%

    If desired, this command can be placed in the AUTOEXEC.BAT file.

 3a. Set Acad device to  Aquila 4.2\in the AutoCAD display device
     configuration menu for AutoCAD 12.
  b. Set Acad device to  ADIP386 V4.0/4.1 Display\in the AutoCAD
     display configuration menu for AutoCAD 10 and 11.

 4. Select the desired mode from the list of available modes in
    the ACAD configuration menu.

 5. Configure options such as dual screen operation (if your system has 
    the capability), menu colors, Graphics Flip Screen feature, mouse,
    printer and plotter as needed. The GFS option enables the AutoCAD 
    text screen to be displayed in the center of the graphics screen.
    This will eliminate the mode switching delay which are found in most
    multi frequency monitors. Do not use this option if a TSR program is 
    being used.
