***************************** VersaCAD 7.0 Driver *****************************
*******************************************************************************

This driver is a TSR type (Terminate and Stay Resident) program. You only need
to install it once in memory each time your machine is powered up. For this
reason, it is recommended that a call to this driver be placed in your
AUTOEXEC.BAT file. The drivers will support VersaCAD Designer 7.0 and VersaCAD
386 7.0. If you are using the real-mode application, the driver used is
VC2_911.COM. If you are using VersaCAD 386, the driver used is VC3_911.COM.

The following resolutions are supported:

Resolution    Colors
640 x 480     256
800 x 600     16
800 x 600     256
1024 x 768    16
1024 x 768    256
1280 x 1024   16

VersaCAD/386 will run faster (redraws 50% faster) if you have a VCPI memory 
manager (QEMM or 386MAX) present and correctly configured. To optimize your 
VCPI memory for use with VCAD/386, all memory outside the DOS 640K range 
should be configured as EMS memory. This means that all the memory that would
normally be allocated to "DOS high memory" should be reserved for use as EMS.

EMS Memory Usage
----------------
As a default, this driver will reserve 512K of EMS memory when invoked. This
will be used to store the display lists needed for fast redraws. While this
should be enough memory to handle most drawings, you can tell the driver to
reserve more EMS space when the driver is loaded. This is done by setting the
environment variable VCAD_EMS= to the number of EMS pages to be reserved. Each
EMS page is 16K in size.

Examples

SET VCAD_EMS=64   Causes the driver to reserve 1024K (64 pages * 16K) of
                  memory when the driver is loaded.

SET VCAD_EMS=0    Tells the driver to reserve no pages of EMS for use. This
                  special case tells the driver not to reserve any EMS. In
                  this case, display list processing is disabled.

Display Resolution
------------------
This driver will use the resolution selected by the ENVIRO program which
ships with VersaCAD. If that mode is unavailable, VersaCAD will not run.

Display List
------------
The main feature of this driver is the built-in display list capability. To
take advantage of this feature, VersaCAD must be told that the driver can
support display listing, and that you wish to use it. To do this, go into the
screen options in ENVIRO, and select the Built-In option under Display List.

To make the most of the display list, use the display list options menu
inside VersaCAD by pressing Ctrl-F5.

To minimize the number of "regens", (where VersaCAD sends down each individual
line) you should zoom the display all the way in, then back out to where you
were in the drawing. After doing this, VCAD will redraw everything from the
local display list, (sketches) and zooming and panning (with the arrow keys)
will be much faster. This is done by using the "Full" function from the
displist list (LIST) menu, then using the "Out" function from the same menu.

To speed up the panning operations (scrolling throughout the drawing can be
done with the arrow keys), use a keyboard utility to increase the "Typematic"
rate of your keyboard. This will increase the rate at which the scrolling
occurs.

Driver Installation for VersaCAD 7.0 Real mode
----------------------------------------------
1.  Insert the 928Movie DOS Drivers disk in the appropriate disk drive.

2.  Change the current drive/directory to the one which contains the VersaCAD
    application.

3.  Copy the file VC2_911.COM from the \VERSACAD subdirectory on the 928Movie
    DOS Drivers disk into the current drive/directory. 

4.  Execute VC2_911.COM.

5.  Run the ENVIRO program and select the "S3 86C911" driver. Reboot the
    system if the installed driver is replacing a previously run driver.

Driver Installation for VersaCAD 386 7.0
----------------------------------------
1.  Insert the 928Movie DOS Drivers disk in the appropriate disk drive.

2.  Change the current drive/directory to the one which contains the VersaCAD
    application.

3.  Copy the files VC3_911.COM and VCAD386.CFG from the \VERSACAD subdirectory
    on the 928Movie DOS Drivers disk into the current drive/directory. 

4.  Execute VC3_911.COM.

5.  Run the ENVIRO program and select the "S3 96C911" screen driver. You will
    be able to choose between "Single Screen" and "Dual Screen" 
    configurations, along with the various resolutions available. Reboot
    the system if the installed driver is replacing a previously run driver.
