Software drivers

The VGA card is 100% VGA compatible. The display drivers described in this
manual are supplied to improve the resolution for each supported software
application package.

The  VGA can support improved text resolution, providing greater readability
when using the supplied drivers in text-based word processing programs. It
also supports higher graphics resolutions, providing greater detail when using
the supplied drivers in graphics-based programs.

In each application section, there will be a brief introduction describing the
application and the revision level of the application supported by the
supplied display drivers.
The installation instructions for each display driver will follow the
introduction section. Follow the instructions carefully to be sure that each
display driver is correctly installed. All of the installation instructions
assume that the Cirrus Logic Drivers Diskette is located in drive A:. If
drive B: is used, the instructions should changed appropriately.

The installation utility (INSTALL.EXE) should be used to copy all display
drivers directly to the appropriate application directories where they may
then be configured by the application software.


Before you begin

It is assumed that the user is familiar with DOS and certain DOS commands.
Please review the installation instructions and the associated DOS commands
before attempting the actual installation.

Not all video modes will be available on all systems. If an extended mode
driver is installed for a video mode that is not available, the application
program will not function properly. There are a number of things that
determine the list of available video modes.  
Some of these include the current monitor type, the amount of installed memory, and the 
revision of the VGA controller. To determine which modes are available before 
beginning the driver installation, it is recommended that the user run the CLMODE 
program and examine the list of available video modes.


Microsoft Windows 3.1

Installing Windows 3.1 display drivers

To install the Windows drivers from the DOS prompt, proceed as follows:
1. Insure that Windows 3.1 is already installed on your computer.
2. From your Windows directory, at the DOS prompt, type SETUP and press
   [Enter] to run the Windows SETUP.EXE program. Follow the instructions on
   the screen. When you come to the screen which lists the hardware and
   software components such as display adapter (e.g. VGA, CGA, etc.),
   keyboard type, mouse type, etc., go to the Display selection by using
   cursor keys to move the highlighted bar and press [Enter].
3. From the next menu listing of display options, scroll to the bottom of the
   list, and highlight the following text:
   	Other (Requires disk provided by a hardware manufacturer)
   Press [Enter], and when prompted, type A:\[Enter]. 
4. You will see the list of drivers and their associated resolutions, such as:

	Cirrus 54xx v1.x, 1280x1024x16
	Cirrus 54xx v1.x, 1024x768x16
	Cirrus 54xx v1.x, 640x480x16.8M
	Cirrus 54xx v1.x, 640x480x256
	Cirrus 54xx v1.x, 640x480x64K
	Cirrus 54xx v1.x, 800x600x16
	Cirrus 54xx v1.x, 800x600x256
	Cirrus 54xx v1.x, 1024x768x256
				
5. Highlight by moving the cursor to the desired display driver, and then
   press [Enter].
6. Continue with the remainder of the SETUP procedure ( If SETUP tells you to
   insert the windows driver diskette , you just type A:\SYSTEM[enter] )


Autodesk Device Interface (ADI) Drivers

Autodesk - ADI 4.2
The ADI 4.2 driver provided with your Cirrus Logic VGA is the TurboDLDClassic
display list driver from Panacea. It has only two purposes:

1. To speed up AutoCAD REDRAWs, PANs, and ZOOMs.
2. To provide a more productive, user-friendly, interface to AutoCAD (via the
   features described later in this manual).

The driver is memory-resident and inserts itself between AutoCAD and the
graphics board. It has no other effect on AutoCADs operation besides
speeding the program up; it runs with AutoShade 2 with RenderMan and 3D Studio
to provide enhanced rendering support, but does not affect the speed of these
programs, since they do not support Display Lists.

Installing TurboDLDClassic does not change any of the AutoCAD program files
or alter any of the drawing files stored on disk. TurboDLDClassic was designed
to be an easy-to-use, feature-filled product that makes using AutoCAD faster
and more productive, not one that makes AutoCAD more complicated and difficult
to use.

How does TurboDLDClassic make AutoCAD run faster? There are three things the 
driver does to speed operation:
1. AutoCAD stores drawings in a hierarchical structure, with simple elements
   intermixed with complex ones. Every time the screen is updated, AutoCAD
   must decode this structure. TurboDLDClassic works differently. While you
   are working, it translates the normal hierarchical structure into a Display
   List, a series of vectors or polygon fills. When you pan or zoom,
   TurboDLDClassic uses the Display List, then writes the resulting vectors
   to the video board hardware. Since the hierarchical structure does not 
   have to be decoded, drawing proceeds very quickly. 
2. TurboDLDClassic also maintains a Drawing Cache. The Drawing Cache is a 
   compressed list which contains the current contents of a viewport. This
   pre-scaled portion of the Display List allows for even faster pans and
   zooms and redraws.
3. TurboDLDClassic gives you numerous new user-interface features, such as
   the bird's eye view. (via the features described later in this manual).

By how much does TurboDLDClassic increase the speed of AutoCAD? PANs and 
ZOOMs, aided by only the Display List, run from two to twelve times faster
than a non-display list driver. The Drawing Cache further speeds things up to
the point that REDRAWs can be up to twenty-five times faster with
TurboDLDClassic, compared to the graphics drivers shipped with AutoCAD.

The features provided by TurboDLDClassic include:
. Bird's eye view.
. Accelerated redraws, pans, and zooms.
. Easy to use - no new commands or special menus to learn.
. Protected-mode ADI 4.2 driver - completely compatible with AutoCAD Release
  12, Release 11/386, 3D Studio and AutoShade 2 with RenderMan.
. No memory conflicts. Works with AutoCAD's built-in Virtual Memory Manager.
. Includes CustomColors , which lets you interactively customize your logical
  and physical colors from within AutoCAD.
. Completely compatible with all Autodesk ADI 4.2 compatible third party
  software.
. Supports all AutoCAD Release 12 features, including rendering to viewports
  and 31-Bit regen space.

TurboDLDClassic requires a '386, '486 or Pentium based PC which supports
AutoCAD Release 12, 11/386, AutoShade 2 with RenderMan, or 3D Studio
V1.x/2.x. Additional extended memory is recommended for optimal performance.


Quick start guide

This section summarizes the basics of installing and using TurboDLDClassic.
Please read the rest of the manual for details.

What does it do? 
TurboDLDClassic 's main function is to speed up AutoCAD pans, zooms and
redraws. The driver accomplishes this by creating and maintaining a Display
List - a fast-displaying object list of the current drawing - dramatically
increasing performance on pans and zooms.
In addition to offering display list speed enhancement, TurboDLDClassic
provides a bird's-eye view to allow you to move around large drawings.

What's the catch? 	
The only resource used by TurboDLDClassic is memory. The driver actively uses
about 300Kbytes of RAM from extended memory for its operation. This memory is
drawn from AutoCAD's memory pool and therefore does not affect normal DOS
operation. The driver is loaded by AutoCAD at AutoCAD load time and is
unloaded when AutoCAD is exited.

Additionally, the Display List size can vary from one tenth to three times the
size of the current drawing file, particularly when using AutoCAD 12's 31-bit
regen space.You may wish to purchase and install additional RAM before
installing TurboDLDClassic, since it shares memory with AutoCAD. If AutoCAD
is using a lot of memory, TurboDLDClassic may not have enough. If there is
significant hard disk activity while you are using TurboDLDClassic, it may
be an indication that you should add more memory to your system.


Installation

Insert the Cirrus Logic drivers diskette into Drive A: (or B:). Run the Cirrus Logic 
installation program (INSTALL.EXE), and choose the option for the 
Autodesk/AutoCAD drivers and specify the drive and directory where you want them 
copied to (such as C:\ACAD\DRV). 
Since the start-up is a little bit different for AutoCAD Release 12 than it is for older 
versions, please follow the instructions for the version of AutoCAD you will be using 
TurboDLDClassic with.
To configure AutoCAD 12
Begin AutoCAD with the reconfigure switch by typing
ACAD -R[Enter]
Choose option 3, Configure Video Display from the AutoCAD configuration menu.
Type Y at the Do you want to select... message to display the available video options 
for AutoCAD.
Select TurboDLD Classic by Panacea Inc. from the list of display options.
If you chose to install TurboDLDClassic into a sub-directory other than ACAD\DRV, be 
sure to modify the ACADDRV environment variable to include that sub-directory. 
Otherwise, the TurboDLDClassic selection will not appear in the list of available 
drivers. 
To configure AutoCAD 11/386
Run the FASTACAD.BAT that was copied to the TurboDLDClassic sub-directory by 
typing:
C:\TURBODLD\FASTACAD[Enter]
The above example shows that TurboDLDClassic was installed on drive C: in the 
TURBODLD sub-directory.
Start AutoCAD and reconfigure it to use TurboDLDClassic by selecting option 5, 
Configure AutoCAD from the AutoCAD main menu. From the next menu, select 
option 3, Configure Video Display. Choose Item 1, P386 ADI 4.0/4.1 (R11) as your 
display device. (For more information, see your AutoCAD 'Installation and 
Performance Guide.')
TurboDLDClassic configuration
After selecting the proper display device, the TurboDLDClassic driver configuration 
menu will appear.
Set-up of TurboDLDClassic requires configuration of its various operating parameters. 
These parameters have been logically grouped into menus based on their interaction 
with AutoCAD. A quick trip through each menu will complete the configuration process. 
Context sensitive help can be obtained by typing  at any menu option. Please note that 
the DLDSETUP.HLP file must be present in order for help to appear. If you get an error 
message, be sure that the file DLDSETUP.HLP is in the ACAD\DRV sub-directory 
(R12), or in the TURBODLD sub-directory (R11).
If at any point during the configuration process you want to change an item on a 
previous screen, just press the [ESC] key to back up. Selecting NO SAVE, EXIT at 
the main configuration menu will return you to the AutoCAD configuration menu 
without making any changes.
At a minimum, a graphics board and screen resolution must be chosen from the Select 
Graphics Board/Resolution menu. If no display options are configured, the driver 
will be automatically configured for Generic VGA, 640 x 480 resolution at 16 
colors.
The first menu, Select Graphics Board/Resolution, configures TurboDLDClassic for 
the graphics board, and display and rendering resolutions to be used. Prior to 
configuring TurboDLDClassic, run the Clmode utility and check the first screen to 
determine which Cirrus Logic chip and how much memory is on your VGA adapter. 
Select Graphics Board - Selects the graphics chip being used
Select Display Resolution - Selects AutoCAD, 3D Studio and AutoShade main 
display screen resolutions
Select Rendering Resolution - Selects AutoCAD 12, 3D Studio and AutoShade 
rendering resolutions
When configuring TurboDLDClassic's display options, the Rendering Board/Resolution 
options described below will automatically appear ONLY when configuring AVE 
Render, 3D Studio or AutoShade. Otherwise, the Display Board/Resolution options will 
be the only menu choices available.
Basic Configuration options set AutoCAD screen characteristics, number of text 
lines in the command-line area, font size and dual screen mode.
AutoCAD Text Lines - Selects number of lines in AutoCAD command prompt area. 
The default is 3 lines, but values from 1 to 10 can be specified. A number larger 
than 3 might be useful if you are using this driver in a high resolution mode with 
small fonts, eliminating the need to frequently swap back and forth between the 
text and graphics screens.
If you do not want any lines of text at the bottom of the display, use AutoCAD to disable 
the command area (see the AutoCAD 'Interface, Installation and Performance Guide' for 
more information). Press [Return] to continue with font selection.
Font Size - Selects AutoCAD display screen font or font file to be used. Choose the 
Font Size you would like to use for your AutoCAD menus, pull-downs, and dialog 
boxes: 8x8/8x14/8x16/12x20/12x24. For resolutions over 800x600 we recommend the 
12x20 or 12x24 fonts. The default is the 8x14 font.
Dual Screen Mode - Enables or disables dual screen operation of AutoCAD.
User Interface options include the parameters for maneuvering within AutoCAD. 
Using these options, the Big Picture, Panacea's bird's-eye view, can be configured 
to suit your needs or allow for better differentiation within a complex drawing. 
Double Click - The Double Click option allows you to set the delay for 
TurboDLDClassic's Big Picture pop-up. This time represents the largest amount of 
time that can elapse between the release of the digitizer button and the subsequent press 
of the same button in order to detect a double click and display the Big Picture. Setting 
this number too low will result in the computer seeing two separate clicks, while setting 
the time too high may slow down response time for single button presses. Values 
between 10 and 30 are recommended.
The Double Click time is measured in hundredths of seconds. PC systems have a timing 
resolution of 5/100ths of a second, therefore, the entered time is rounded by the driver to 
most closely approximate the nearest multiple of 5. This means that a time setting of 23 
is the same as a setting of 27, both of which get rounded to 25 (or one-quarter of a 
second). In simplest terms, when adjusting the timing value, it is best to use multiples of 
5.
BP Button - Sets mouse/digitizer button to use for Big Picture. With the BP Button 
option, TurboDLDClassic gives you the flexibility to use a double click on an available 
digitizer/mouse button as a Big Picture pop-up button. On the BP Button menu line, 
enter the number of any available digitizer button other than button 1 - button 1 is 
reserved as the pick button. Within AutoCAD, simply double click the chosen button to 
invoke the Big Picture.
BP Highlight Mode - Controls how the Big Picture will appear on the screen. Patt 
Line will display the Big Picture using dotted lines to form the outer bounding box 
and the zoom crosshairs. XOR Rect will use a contrasting rectangle to display the 
Big Picture. The Both option will use a combination of Patt Line and XOR Rect to 
distinguish the Big Picture.
BP Refresh - In it's fastest mode, TurboDLDClassic does not refresh the Big Picture 
until a DLDREFRESH command is issued. Depending on a drawing's complexity, in 
this mode, the Big Picture could become confusing, displaying vectors that are now 
actually erased, and no longer part of the drawing. To configure the Big Picture to be 
updated as objects are drawn or erased, enable the BP Refresh. If speed is a major 
concern, disable it.
BP Cache - Enables or disables TurboDLDClassic's internal memory cache for Big 
Picture functions. This cache will speed up Big Picture operations on some graphics 
platforms, primarily on TIGA-based graphics boards. For this reason, the BP Cache is 
normally disabled. As a reference, on VGAs, the performance benefit of the BP Cache is 
as little as 1%. With a TIGA-based graphics board, however, the performance benefit of 
the BP Cache is as high as 400%.
The Expert Configuration menu sets the function of TurboDLDClassic itself. This 
menu allows for customization of the driver for speed or to adjust for memory 
constraints.
Display List - Enables or disables the display list feature of TurboDLDClassic. This 
option should always be set to enable, disabling the Display List will cause 
TurboDLDClassic to run as an ordinary non-display list driver.
Drawing Cache - Enables or disables TurboDLDClassic's internal drawing cache, a 
compressed list of the current viewport, which speeds up pans zooms and redraws. As in 
the Display List option, Drawing Cache should normally be enabled. In low memory 
situations, it may be desirable to disable the Drawing Cache. Disabling the drawing 
cache will free-up memory for AutoCAD but may or may not have a visible effect 
on your ZOOM and PAN performance. For example, on VGAs, the performance 
benefit of the drawing cache is as little as 5%. With a TIGA-based graphics board, 
however, the performance benefit of the drawing cache is as high as 400%.
AutoCAD Logical Drawing Space - Using AutoCAD 31-Bit Space, configures 
TurboDLDClassic for use with AutoCAD R12's 31-Bit logical drawing space. When set 
to Yes, the driver will use AutoCAD's extended 31-Bit drawing space. Selecting No, will 
use a 15-Bit drawing space, similar to that of AutoCAD R11.
The 31-Bit logical space allows you to extend your Regen-less zooming ability by a 
factor of several million, at the cost of more memory. Additional memory is used by 
AutoCAD for the drawing space, and by TurboDLDClassic for the Display List. 31-Bit 
zooming and panning is about 10%-20% slower than for 15-Bit logical space. The Use 
AutoCAD 31-Bit Space setting is ignored for AutoCAD R11 installations.
Internal Command Echo - The echo of TurboDLDClassic internal commands can be 
enabled or disabled with the Internal Command Echo option. If you would like to see 
TurboDLDClassic's internal commands display at the AutoCAD command line as they 
are executed, enable this option.
Big Picture Zoom Mode - Sets the Big Picture (BP) zoom definition area display 
options. In a zoomed view of the static BP, as the current viewport is zoomed or 
panned, Float mode causes the image in the BP to move around within the bird's-
eye window, keeping the zoomed viewport area fixed in the center of the bird's-eye. 
Freeze mode will lock the current BP contents into place to provide a better overall 
frame of reference.
Regen Mode - As a convenience feature, a Regen Mode option has been added to 
TurboDLDClassic. A Fast Regen will store the AutoCAD drawing until the Display List 
has been created, and then display it, all at once. The Incremental mode displays the 
drawing in 'chunks' as the display list is created. The Fast mode causes Regens to 
process approximately 5%-10% faster than the incremental. Neither mode changes 
memory requirements.
After all options have been set, use the arrow keys to scroll down to the Save and Exit 
option and then press the [Enter] key to continue.
Next, configure the AutoCAD screen display characteristics and then type [Y] to accept 
the changes.
Exit to the AutoCAD drawing editor to begin using TurboDLDClassic.
The last step in setting-up TurboDLDClassic is to configure the colors for AutoCAD. 
From the AutoCAD Command Line, type DLDCOLOR[Enter], to start 
CustomColors, TurboDLDClassic's color configuration utility. Make any desired color 
changes and then Save the new color palette and then Exit to return to the drawing 
editor.
Verifying your TurboDLDClassic installation
To verify that TurboDLDClassic is running and installed correctly, follow one of these 
two simple tests.
If you have the AutoCAD side menu enabled, look for the Panacea Logo in the lower 
right-hand corner.
If you are running AutoCAD without a side menu, type DLDVER[Enter] at the 
AutoCAD command prompt. If TurboDLDClassic is loaded and running, this command 
should return your current version, and serial number.
Reconfiguring TurboDLDClassic
To reconfigure TurboDLDClassic follow the instructions below for your version of 
AutoCAD, Release 12 or Release 11.
AutoCAD Release 12
If you need to make changes to your Release 12 TurboDLDClassic configuration, type 
CONFIG[Enter] at the AutoCAD command prompt or use ACAD -
R[Enter] when starting the program. Select option 3, Configure Video Display. 
Answer No[Enter] to the Select a new videodriver ... prompt to start the 
TurboDLDClassic configuration program. Make the desired changes to the driver and 
then Save and Exit to continue to the AutoCAD drawing editor.
AutoCAD release 11
To change a Release 11 configuration, select option 5, Configure AutoCAD from the 
AutoCAD main menu, and then from the configuration menu, select option 3, 
Configure Video Display. Answer no to the Select a new video driver ... prompt to 
start the TurboDLDClassic configuration program. Change the desired driver options. 
Save and Exit to return to the AutoCAD configuration menu. Open or begin a new 
drawing. 
To completely reconfigure TurboDLDClassic using Panacea's defaults, delete 
DLDSETUP.DAT from either the \ACAD\DRV sub-directory (R12) or the TURBODLD 
sub-directory (R11) and then follow the Driver Configuration instructions earlier in this 
chapter.
Configuring an AutoCAD 11 environment
During the TurboDLDClassic installation process, a FASTACAD.BAT file is created 
and placed into the TURBODLD sub-directory. FASTACAD.BAT contains four lines 
that set four separate environment variables: DLDCFG - used by TurboDLDClassic to 
find all of its configuration files; and DSPADI, RCPADI, RDPADI - used by AutoCAD, 
3D Studio and AutoShade 2 w/RenderMan, respectively, to find the driver file. 
FASTACAD.BAT must be run prior to starting AutoCAD R11 and only needs to be run 
once per system boot. For automatic loading of the environment variables, 
FASTACAD.BAT may be added to the AUTOEXEC.BAT file or an AutoCAD start-up 
batch file. 
To add FASTACAD.BAT to your AUTOEXEC.BAT file, insert the line	
CALL D:\TURBODLD\FASTACAD
anywhere in the file. The above example assumes that FASTACAD.BAT resides in a 
sub-directory on drive D: called \TURBODLD.
If you dont wish to put FASTACAD in your AUTOEXEC.BAT file, you may put it in a 
batch file which also starts AutoCAD, or simply remember to run the file before starting 
AutoCAD.
If you get the message Out of Environment Space when you run FASTACAD.BAT, 
you will need to enlarge your system's environment. This is accomplished by adding 
the following line,
SHELL=C:\COMMAND.COM /P /E:768 
to your CONFIG.SYS file. The /E:768 specifies an environment size of 768 bytes. 
Change this number as appropriate. You will need to reboot after modifying your 
CONFIG.SYS file, in order for the changes to take effect. 
Configuring AutoShade, 3D Studio and AVE Render
AutoShade
To configure AutoShade v2.0 to use TurboDLDClassic, first run the FASTACAD.BAT 
file from your TurboDLDClassic sub-directory to set the AutoShade environment 
variables. Next, start AutoShade with SHADE /R[Enter], which will allow you to 
reconfigure AutoShade. For the display device, select P386 Autodesk Device Interface 
display driver, and for the rendering display select the P386 Autodesk Device 
Interface rendering driver. If you are running the display and rendering screen on the 
same monitor (i.e. single monitor), make sure to tell AutoShade this. A single monitor 
approach will require a redraw of the display screen after a rendering screen.
Next, follow the same installation steps that were used to select the graphics board and 
display and rendering resolutions for AutoCAD.
----------------------------------------------------------------------------------------

3D Studio relesae 1.x & 2.x & 3.x

Configuring 3D Studio requires three steps. First, you need to set the
environment variables for 3D Studio by running the PANA3DS.BAT file that was
copied into your TurboDLDClassic sub-directory. Next, edit the 3DS.SET file,
located in your 3DS directory. The following three lines may be changed to
use the RCPADI rendering driver. Locate the lines that begin with
	RENDER-DISPLAY	
	MAIN-DISPLAY	
	MATERIAL-DISPLAY
and change them to read
	RENDER-DISPLAY=RCPADI	
	MAIN-DISPLAY=RCPADI
	MATERIAL-DISPLAY=RCPADI
Make sure to remove the ';' or any spaces that may be present at the beginning
of the line.
It is only necessary for the RENDER-DISPLAY line to be set to RCPADI in order
to render at high resolution. If you do not need a high resolution main
display screen or if you will not be using the materials editor, you may keep
MAIN-DISPLAY and MATERIAL-DISPLAY set to their defaults.

For 3D Studio 1.x, there is no RENDER-DISPLAY line. The corresponding line is
DEFAULT-DISPLAY and should be changed to read	
	DEFAULT-DISPLAY="RCPADI"
The quotes around RCPADI must be used for this version of 3D Studio.
The MATERIAL-DISPLAY should only be configured for RCPADI when BOTH the
Display AND Rendering Resolutions of TurboDLDClassic are configured for 256
color resolutions. An unpredictable Materials Editor screen will appear if
anything other than 256 colors is selected. If you are unsure about the
function of the Materials Editor screen, use the Materials Editor as VGA, you
should not have any problems at all. Please note too, that the use of the
Materials Editor will not give you any more colors to choose from.

Save the above changes and start 3D Studio to begin the last part of the
configuration procedure.

From your 3D Studio directory, delete the file 3DADI.CFG by typing
	DEL 3DADI.CFG[Enter]
This will cause 3D Studio to start in its reconfiguration mode. Start 3D
Studio by typing 3DS[Enter].

During the 3D Studio reconfiguration start-up, you are prompted with a series
of questions. After the first 3D Studio question appears and is answered, the
TurboDLDClassic configuration program will appear. Select a graphics board and
display and rendering resolutions as you would for AutoCAD use.

Because RCPADI device drivers, by definition, are combined display and
rendering devices, during 3D Studio reconfiguration, you will be brought to
the TurboDLDClassic configuration menu more than one time, once each for
Display and Rendering. It is not necessary to select display and/or rendering
resolutions a second time. Simply press the [Enter] key to remove the help
screen and then highlight Save and Exit to continue to the next question.
Also if FASTACAD.BAT is used instead of PANA3DS.BAT to define the AutoCAD
operating environment, the TurboDLDClassic configuration menu will also
appear for RDPADI and DSPADI devices if they are present.


3D Studio v3.x:

Panacea's TurboDLDClassic drivers will run with 3D Studio release 3.x. Please
use 3D Studio's default RCPADI VIBRANT GRAPHICS DRIVER CONFIGURATION.
Follow the Vibrant Graphics Configuration Program Steup Procedures that are
found in your 3D Studio 3.x Installation Manual for ADI 4.2 Drivers.

From your Turbodld Subdirectory run PANA3DS.BAT to set the 3D Studio
environment settings.
Run 3DS VIBCFG.
During Configuration for Vibrant Graphics there will be four categories,
Main-Display, Materials-Display, Render-Display, and Flic Playing. For these
four catedories set RCPADI.

When Vibrant Graphic settings are complete click OK to exit and save setting.
The Setup for Turbodld Classic Drivers will then commence. Follow the menus
to Setup Display and Renderung Screen. Save and Exit to 3D Studio.

Please note that the out of the box CIRRUS LOGIC drivers that are supported
in 3D Studio release 3.x are supplied and maintained by Autodesk.

Note:
TurboDLDClassic only provides still rendering support for 3D Studio. 
TurboDLDClassic will not play back rendered .FLI or .FLC files. This is a
limitation of 3D Studio.The Mapping Icon colors, which are usually yellow and
green, will appear as black when using any external ADI driver. Also, 3D
Studio has problems with large fonts. It is recommended that you use the
default font settings.


AVE Render
AutoCAD 12's AVE Render uses TurboDLDClassic's rendering capabilities to render 
objects and drawings. If AVE Render has never been configured, when you first select 
the AutoCAD render command, you will be forced to run through the configuration 
process. You will be prompted as follows.
Select a Rendering Display Device. Since TurboDLDClassic is a combined 
display/rendering device, choose item 1, P386 ADI Combined Display/Rendering 
Driver from the available choices.
Configure the Rendering Graphics Board and Resolution. Here the 
TurboDLDClassic configuration program will appear on the screen. Press the [Enter] 
key to continue past the help screen and display the Rendering Configuration menu. 
Choose Select Graphics Board/Resolution to display graphics board and resolution 
menu selections. First, choose Select Render Graphics Board to select the graphics 
board to be used for renderings. Next, choose Select Render Resolution to select the 
desired rendering resolution from the list of available choices. Select Return to 
Previous Menu and then select Save and Exit.
Select Render Mode. Then select the rendering mode for TurboDLDClassic. Select 
either Render to Viewport or Select a Render Hard Copy Device. If you are using a 
render hard copy device select your device type from the list of choices. If you are 
not using a hard copy device, accept the default of NULL.
After configuring AVE Render, you will return to the drawing to render the current 
drawing.
If you have previously configured AVE Render, type RCONFIG[Enter] at the 
AutoCAD command prompt to manually display the Render Configuration menu. 
Follow these steps to re-configure AVE Render.
Select option 2, Configure Rendering Device to choose a new rendering driver. 
Answer [Yes] to the Select Different Rendering Device question.
Select option 1, P386 Combined Display/Rendering Driver.
Configure the rendering graphics board and resolution. Here the TurboDLDClassic 
configuration program will appear on the screen. Press the [Enter] key to continue 
past the help screen and display the Rendering Configuration menu. Choose Select 
Graphics Board/Resolution to display graphics board and resolution menu 
selections. First, choose Select Render Graphics Board to select the graphics board 
to be used for rendering. Next, choose Select Render Resolution to select the desired 
rendering resolution from the list of available choices. Select Return to Previous 
Menu and then Save and Exit.
Select the rendering mode for TurboDLDClassic. Select either Render to Viewport or 
Render to Screen depending on how you wish to view your renderings. Note that in 
order to render to a viewport you must be using a Display resolution with at least 
256 colors. Otherwise, AVE Render will not allow a render to viewport selection.
Select Exit to the Drawing Editor from the Render Configuration menu and then 
type [Y] to keep the changes you've just made. Press the [F1] key to change to 
the graphics screen if necessary.
Changing colors
Included with TurboDLDClassic is the CustomColors color configuration utility. What 
is so unique about CustomColors is that it gives you the ability to modify all of your 
changeable AutoCAD colors, including menu colors, text colors, dialog box colors, and 
even drawing colors, while running AutoCAD.
CustomColors simulates an AutoCAD screen, complete with all possible objects. At the 
AutoCAD drawing editor command line, type DLDCOLOR[Enter] to edit the color 
configuration. Once you enter the utility, you are provided with the following 
configuration menu at the bottom of the screen:
(O)bject, 
(D)rawing, 
(P)hysical, 
(A)DI reset, 
(V)GA reset, 
(L)oad, 
(S)ave, 
(E)xit
The menu items perform the following functions.
Object - Selecting this option will allow you to change the color of any AutoCAD 
screen object, such as the graphics area background color, the menu area text 
color, or the border line color.
Select the object whose color you want to change by moving the highlight box around 
with the left and right cursor control keys and pressing [Enter] when you have 
highlighted the desired object. Note that a one line description of the object type is 
displayed at the top of the screen as you move the box around.
Once you have selected the object, another highlight box will appear around the color 
boxes nearest to the bottom of the screen. These are the physical colors that the video 
board supports. Use the left and right cursor keys to select the physical color to be used 
for the object you have selected and press [Enter]. The screen will quickly redraw with 
the new color selection for the object you have chosen, and you will be back at the start 
of object selection in case you want to change the color of another object.
Note that at any time during color configuration, you can press the [Esc] key once or 
twice and return to AutoCAD. Also, pressing the question mark [?] key will provide you 
with context sensitive help.
Drawing - This option allows you to modify AutoCAD drawing colors 0, 8 and 9, in 
a fashion similar to the way you change object colors. 
When this option is selected, a highlight square appears in the drawing color area of the 
simulated AutoCAD display. The square can be manipulated using the four cursor keys. 
You may notice that the drawing color portion of the display is laid out just like the 
CHROMA drawing supplied with AutoCAD. When you press [Enter], the highlight 
moves down to the 16 physical colors, just as it does during the object 
color selection. Using the arrow keys, pick the physical color you want to 
represent the selected drawing color. Press [Enter] to have your selection take 
effect.
Physical - choosing the Physical option from the menu allows you to alter the red, 
green, and blue components of the physical colors. A highlight box will appear in 
the row of 16 physical colors at the bottom of the screen.
Use the arrow keys to select the color you wish to edit and press [Enter]. Three sliders 
will appear near the bottom of the display, with the horizontal position of the slider for 
each of the color components (red, green, or blue - RGB) indicating the relative intensity 
of the component. You can use the left and right arrow keys to move the slider for the 
selected component, or type in a number from 0 to 255. 
Many graphics boards do not support 255 different intensities for each color component. 
Therefore, when you enter an intensity, Custom Colors will round it to the nearest 
intensity which your graphics board supports. For example, VGAs support 64 intensities 
per RGB color component. This means intensities increase in multiples of 4 (256/64), 
therefore an intensity of 0 is the same as an intensity of 3.
The up and down arrows allow you to select which component you want to alter. As you 
manipulate the sliders, all objects on the display that are of the same color as the 
selected physical color will change in hue. This way you can visually determine the most 
appropriate setting for your display. Pressing [Enter] will set the RGB values you have 
selected for the physical color you were modifying.
ADIreset - constructs a default ADI color palette, as defined in the Autodesk Device 
Interface Driver Development Kit.
VGAreset - constructs a default VGA color palette in the first 16 color entries. The 
remaining palette colors remain identical to those used for ADI devices.
Load - reloads the color information from the file DLDCOLOR.DAT. It will be 
loaded from the directory pointed to by DLDCFG (AutoCAD R11), or from the 
AutoCAD R12 \DRV directory. If DLDCOLOR.DAT cannot be found, an error 
message will be displayed.
This command is useful because it allows you to go back to your previously edited color 
configuration in case you have made some mistakes in configuring your colors that you 
want to undo.
Dont Accidently Wipe Out Your Changes. Selecting ADIreset, VGAreset, or Load 
will irrevocably wipe out any current color changes you may have made, unless you 
have just saved your new setting, so use them only when you really need to, such as 
when you have made so many color changes that you cant seem to get back to a 
reasonable place and just want to start over.
Save - Saves the current color palette to DLDCOLOR.DAT. It will be saved to the 
directory pointed to by the DLDCFG environment variable in FASTACAD, or to 
the \ACAD\DRV (R12) directory if FASTACAD is not used.
Exit - Exits CustomColors. If you have made palette changes, but not saved them, 
you will be asked if you want to save your changes before exiting.
When running at more than 8 bits-per-pixel (256 colors), setting physical colors via 
DLDCOLOR will have no visible effect until a SAVE and EXIT occurs.
TurboDLDClassic commands
TurboDLDClassic offers AutoCAD users many features and productivity options. This 
section alphabetically lists the basic commands found in TurboDLDClassic and 
provides the correct syntax for their usage. For a brief summary of TurboDLDClassic 
commands type DLDHELP at the AutoCAD command prompt.
The most important feature of TurboDLDClassic is the addition of a world view called 
The Big PictureTM or BP for short. Bringing up the BP allows you to view where in the 
current drawing you are currently located in your active viewport, and it also gives you 
the ability to dynamically move to another part of the drawing without having to exit the 
function youre currently executing.
DLDBIGPIC
To call up the Big Picture, at the AutoCAD command line, type 
DLDBIGPIC[Enter], or double click the right mouse button or button 2 on your 
digitizer puck. (if you havent redefined your BP Button double click). This will bring 
up the BP on the display. You will see cross-hairs and a highlighted section indicating 
which part of the whole drawing youre currently viewing - the size of the image will be 
determined by the AutoCAD logical drawing space being used, 15-Bit or 31-Bit. The 
selection or pick box will have an 'X' through it. Move the mouse/digitizer around to 
locate your pick box. If you cant see a small box moving, click the left mouse 
button (the pick button) to size down the pick area. In size mode, the pick box will 
have a right pointing arrow in it ('-->'). If the contents of the BP are too small to 
work with, you may increase the size of the image in the window by pressing the 
[+] key on your numeric keypad this performs an incremental zoom within 
the BP. Likewise, pressing the [-] key will reduce the size of the contents 
of the BP. Pressing the [Home] and [End] keys will put the BP into its smallest 
and largest size, respectively. The smallest BP size is defined as being exactly the same 
view as that in the viewport referenced by the BP. The largest BP size is defined as the 
largest image possible without causing a Regen.
The BP pick box is always proportioned to the proper aspect ratio for the current 
viewport. Clicking the pick button again will put you back into the pick box move mode 
('X'). This operation is very similar to using the Zoom Dynamic feature of 
AutoCAD. Once you have positioned the pick box on the area you would like 
displayed in the active viewport, click any button other than the pick button to 
initiate the zoom, or press the [Enter] key. If you want to abort the operation, just 
hold any button down, other than the pick button, until the BP disappears. You can also 
hit any key on the keyboard, other than [Enter], to cancel the BP. Note that the BP is 
updated with new drawing commands, but that moves or erases will not update the 
image unless BPREFRESH is enabled. A DLDREFRESH or a REGEN will manually 
update the BP with the current drawing changes.
DLDBPCACHE*
Enables or disables TurboDLDClassic's internal cache for BP features. This cache 
speeds up TurboDLDClassic's Big Picture functions. DLDBPCACHE is normally 
disabled. Performance benefits of the BP Cache with will vary from one graphics 
platform to the next. For example, on VGAs, the performance benefit of the BP Cache is 
as little as 1%. 
DLDBPDIM
Resizing and repositioning the BP can be accomplished by typing this command at the 
AutoCAD prompt. DLDBPDIM allows you to tell the driver where you want the BP 
placed and how large you want it to be. The size is limited to being between one-quarter 
and one-half the width of the display. This command functions like the pan/zoom 
selection box in the BP, as far as positioning and dimensioning goes. To abort, hold the 
right mouse button, or any other digitizer button, down until the moving box disappears.
DLDBPFREEZE
Sets the Big Picture (BP) zoom definition area display options. DLDBPFREEZE toggles 
the Big Picture Zoom Mode parameter in TurboDLDClassic's Expert Configuration 
Menu.
In a zoomed view of the static BP, as the current viewport is zoomed or panned, Float 
mode causes the image in the BP to move around within the bird's-eye window, keeping 
the zoomed viewport area fixed in the center of the bird's-eye. Freeze mode will lock the 
current BP contents into place to provide a better overall frame of reference.
DLDBPHILIGHT*
Changes the highlight used to display the Big Picture among three modes, Patt Line, 
XOR Rect, and Both. Patt Lines will use dotted lines to outline the Big Picture pick box. 
XOR Rect will use a contrasting rectangle to highlight the pick box, and Both will use a 
combination of Patt Lines and XOR Rect.
DLDBPREFRSH*
This convenience feature of TurboDLDClassic, toggles the Big Picture update mode. If 
disabled, the BP is updated manually by issuing a DLDREFRESH command. When 
enabled, DLDBPREFRSH will cause the BP to refresh automatically when an object is 
drawn or erased. The BP operations therefore will be slower with DLDBPREFRSH 
enabled.
DLDBPSTATIC
Toggles the BP to stay on the screen at all times. Use this command if you want the BP 
on the screen in order to conveniently move into it whenever you want to zoom or pan. 
Typing DLDBPSTATIC will put up the BP at the position you set with DLDBPDIM. 
Note that the static BP will disappear when other menus pop-up on the screen, and it 
will also disappear if you draw any objects which may overwrite the BP. With these 
exceptions, the BP will remain on-screen until you either exit the drawing screen or you 
type DLDBPSTATIC again.
DLDCOLOR	
Invokes CustomColorsTM, Panacea's color configuration program. 
DLDCOMPACT
Forces a manual garbage collect of Display List memory thereby returning unused 
display list memory back to the AutoCAD memory pool.
DLDDCACHE*
This command toggles the TurboDLDClassic drawing cache on and off. The Drawing 
Cache is a compressed form of the current viewport which speeds pans, zooms and 
redraws 
DLDDLIST*
This command toggles the display list function of TurboDLDClassic on and off.
Please note that if the display list is turned off, you will be running AutoCAD as though 
you were using a standard non display list driver - pans, zooms and redraws will be 
MUCH slower with DLDDLIST disabled.
DLDECHO*
Toggles internal TurboDLDClassic command echoing at the AutoCAD command line. 
When TurboDLDClassic commands are executed via the digitizer or pop-up menus, they 
generate internal commands which will be displayed at the AutoCAD command line if 
DLDECHO is enabled. Disable DLDECHO to simplify the command line.
DLDHELP
Provides a list of TurboDLDClassic commands with one-line description of each, within 
AutoCAD. It's recommended that you flip to the text screen by pressing the <F1> key to 
view the output.
DLDREFRESH
Refreshes the Big Picture to reflect the most current changes to a drawing. If the static 
BP is up, it will be updated. If not, the next time the BP is brought up, it will contain a 
current representation of your drawing, provided no changes were made between the 
DLDREFRESH command and the DLDBIGPIC command. For Automatic update of the 
Big Picture, see the DLDBPREFRSH command above.
DLDSTAT
Displays the current TurboDLDClassic status. A listing of the current TurboDLDClassic 
parameters will be displayed at the AutoCAD command line. A flip to the graphics 
screen is recommended for this command. 
DLDUSAGE
Use DLDUSAGE if you want a to-the-byte breakdown of how memory is being used, 
specifically for display list processing. DLDUSAGE returns information regarding the 
memory each viewport is occupying. Since AutoCAD supports multiple viewports, it is 
possible to have multiple display lists.
DLDVER
Displays the TurboDLDClassic version, serial number and registered user's name at the 
AutoCAD command line.
DLDVISREGEN*
Toggles between the Fast and Visible Regen modes of TurboDLDClassic. A Fast Regen 
will create the display list and then display the drawing all at once. A Visible Regen will 
display the drawing in chunks as the display list is created. This command is a dynamic 
form of the Regen Mode parameter in the Expert Configuration Menu. Since 
TurboDLDClassic's Fast Regen mode is faster than AutoCAD's, we highly recommend 
its use.
Please note that the commands above with a '*' following them, when issued within 
AutoCAD, will override the selections made during TurboDLDClassic configuration, 
for the current drawing session only. Exiting AutoCAD and subsequently restarting will 
cause all feature settings to revert back to those selected in the TurboDLDClassic 
configuration menu. If you wish to make the current changes permanent, reconfigure 
TurboDLDClassic.
Memory usage and lists
TurboDLDClassic shares extended memory with AutoCAD via the PharLap Virtual 
Memory Manager. This means that TurboDLDClassic will automatically page to disk if 
it uses up all the RAM that AutoCAD has left for its use. See the AutoCAD 'Installation 
and Performance Guide' for more information on Virtual Memory Management. 
Please note that if you start seeing excessive hard disk accesses during PANs, 
REDRAWs, and ZOOMs while using AutoCAD with TurboDLDClassic, try using the 
DLDCOMPACT command. If this doesnt affect the amount of disk access its probably 
time to add more memory to your system. Contact your AutoCAD dealer for assistance 
in upgrading your memory.
Regarding display list memory, its important to realize that TurboDLDClassic speeds 
up AutoCAD operations by creating a Display List in memory, and sending that list to 
the graphics board for pans, zooms and redraws. But a display list takes up memory.
How much memory?
For production use, we recommend that at least 1 megabyte is available for 
TurboDLDClassic. To determine how much memory AutoCAD is using, use the status 
command while in AutoCAD (refer to the AutoCAD 'Installation and Performance 
Guide' for more information). The Display List for a simple drawing like the shuttle 
Columbia might only require 20 Kbytes for the Display List. Complex drawings may 
require several megabytes. We have seen Display Lists for a drawing range from one-
tenth the size of the drawing file to three times the size; in general, the Display List 
averages about the same as the DWG file size. This means that you should count on the 
Display List generally taking up as much as twice the DWG file size. Also, complex 
objects such as circles and text "expand" when translated into display list format, so a 
drawing with a lot of complex objects and text will have a larger Display List than a 
simpler drawing. 
Keeping the Display List small
Text takes up a disproportionate amount of space in the Display List. To keep the list 
small, put text in its own layer of the drawing. Then dont display the text layer when 
editing the rest of the figure. This will keep memory consumption down and speed up 
PANs, REDRAWs, and ZOOMs.
Read the AutoCAD manuals
The AutoCAD manuals have an excellent section on performance, concentrating on 
memory usage. To get the most performance out of the program, read the appropriate 
sections of those manuals as well as this one. 
Tips and tricks
Upgrading from older Panacea DLD drivers
Be sure to remove any reference to previous DLD driver commands (FASTACAD calls 
or SET parameters) or sub-directories that may be in your AUTOEXEC.BAT file or in 
AutoCAD start-up batch files. Such references could cause AutoCAD and 
TurboDLDClassic to look in the wrong place for setup information.
If have been using a previous Panacea DLD driver and wish to use the color palette you 
customized for it with TurboDLDClassic, you may copy the DLDCOLOR.DAT file from 
your older DLD's sub-directory to the sub-directory you specified during the 
TurboDLDClassic installation process.
Maneuvering Through AutoCAD
Zooming
When zooming into an image, be aware of your AutoCAD grid snap setting. If you are 
zoomed extremely far into a drawing and you are having trouble moving your digitizer 
cursor, you may be snapping to a point which is not part of the zoomed viewport. If the 
cursor only moves to a single point, or is not on screen at all, turn the grid snap off.
TurboDLDClassic and Paper Space
TurboDLDClassic features do not work in AutoCAD's Paper Space. The execution of 
any TurboDLDClassic command in Paper Space will result in an error message at the 
command prompt.
Zoom Dynamic
We do not recommended using ANY TurboDLDClassic features while in the Zoom 
Dynamic mode of AutoCAD. Because TurboDLDClassic cannot determine when Zoom 
Dynamic has been initiated, unpredictable results will occur. Use the Big Picture 
feature of TurboDLDClassic to accomplish the same task as Zoom Dynamic, in a much 
more efficient fashion.
Switching Color Modes
When switching color modes, (i.e. from 16 to 256 or vice versa) the DLDCOLOR 
command should be run in order to reconfigure your color palette for the number of 
colors selected. A black cursor and disappearing crosshairs are both symptoms of a color 
palette problem.
AutoCAD R12's CONFIG command
Configuring TurboDLDClassic in the middle of a drawing session using the CONFIG 
command is a bit like exiting and re-starting AutoCAD. If are using the static Big 
Picture, you will have to re-initialize it after returning from the Configuration menu.
Sticky Cursors
Sometimes, when using the Big Picture, the digitizer cursor will appear to stick to the 
edge of the bird's-eye. This is normal and is the result of the digitizer puck responding to 
the whole screen area while the Big Picture only occupies a small portion of the screen. 
Because of the difference in resolutions between the screen and the digitizer, when the 
screen cursor enters the Big Picture area, the digitizer puck has more drawing area to 
cover in order to get to the same location as the screen cursor.
Using AutoCAD Commands
Since TurboDLDClassic is totally transparent to users with respect to using normal 
AutoCAD commands to REDRAW, PAN, and ZOOM, you still have to suffer from some 
of AutoCADs nuances. One of these nuances is that ZOOM ALL and ZOOM EXTENTS 
both force a REGEN, because AutoCAD does not keep track of various boundaries 
necessary to avoid the REGENs. And REGENs are rather time-consuming and dont use 
any display list processing to speed themselves up. One way around this problem is to 
use another of AutoCADs built-in features, namely the VIEW command.
When you first load your image and see the whole drawing on the screen at once, just 
type VIEW Save ALL[Enter], which will save the display position you see 
under a view named 'All'. Then, after youve done some detailed editing 
and want to return back to the big picture, type VIEW Restore 
ALL[Enter], instead of ZOOM All[Enter] or ZOOM Extents[Enter], and the 
full drawing will be restored to the display at display list speeds, without a REGEN.
Another nuance of AutoCADs is that if you zoom in too far or pan over too far, you 
may inadvertently cause a REGEN. AutoCAD again provides a very simple solution: the 
REGENAUTO command. Just type REGENAUTO Off[Enter] at the AutoCAD 
command prompt, and automatic REGENs will be disabled. The REGENAUTO setting 
is also saved as part of your drawing file, so you only need to execute it once per 
drawing. You may even want to set REGENAUTO off in your ACAD.DWG drawing 
template so that all your drawings are created with REGENAUTO set off.
Third-Party Software
If you are having trouble with TurboDLDClassic and third-party AutoCAD 
applications, be sure that the third-party application supports ADI 4.2. In order to use 
the ADI 4.2 specification, third-party applications require new T-Drivers and therefore 
must be revised. If an application does not specifically say that it is ADI 4.2 compatible, 
it probably is not. Check with the manufacturer to be sure.
If your third-party application is ADI 4.2 compatible and you are having trouble using 
TurboDLDClassic, try running AutoCAD without the third-party application to try to 
isolate the problem. Also, try the third-party application with the VESA compatible 
driver shipped with AutoCAD, this will also help to isolate the source of the problem.
Also note that any third-party TSR that needs to access the display may not work 
properly when using AutoCAD with any advanced ADI display driver, especially if the 
TSR switches graphics modes. Most TSRs will not support the same graphics platforms 
as TurboDLDClassic and therefore, will not be able to accommodate mode switching 
back and forth.

You may create multiple driver sets with different display resolutions. To run
Lotus 1-2-3 or Symphony with a specific driver set, type: 
	123 SETNAME [Enter] or
	SYMPHONY SETNAME [Enter]
where SETNAME is the name of the desired driver set.


Lotus 1-2-3 v3.x

To install a Lotus 3.0 or 3.1 display driver, proceed as follows:

1.It is assumed that Lotus 1-2-3 v3.0 or v3.1 is already installed on your
  hard disk, using thestandard Lotus installation utility.  To install this
  driver, make the directory containing 1-2-3 v3.0 the current directory.
  For example, if 1-2-3 is in the directory named 123R3, then type the
  following command:
	CD \123R3[Enter]
2.One of the files used in the driver installation is named INSTALL.DDF.
  This is a text file used by the 1-2-3 installation utility, containing
  information on each of the drivers and modes of operation.  If you have
  been using a driver supplied with another graphics adapter, you may want to
  make a backup copy of the INSTALL.DDF file currently in your 1-2-3 directory.
	COPY INSTALL.DDF INSTALL.BAK [Enter]
3.Run the Cirrus Logic installation program (INSTALL.EXE), and choose the
  option for the Lotus 123 drivers and specify the drive and directory where
  you want them copied to (such as C:\123R3). If the INSTALL.DDF has been
  copied to a backup fille (see step 2 above), answer YES to the prompt to
  confirm overwriting the file.
4.Now run the Lotus installation utility by typing:
	INSTALL[Enter]
5.Select Change selected equipment from the list.  Note: If you are currently
  using another driver supplied with a graphics board, it may be necessary to
  choose First-time installation.
6.Select Modify Current DCF, or Choose another DCF to modify, according to
  your preference.  The following procedure is valid for either selection.
7.Select Change Video Display.  This will present you with a list of all the
  display types	provided with the 1-2-3 distribution, with two additional
  choices.  GD542x 100 Column Display (800x600 resolution) supports 100x31,
  100x42, and 100x75 16 color modes.  GD542x 128 Column Display (1024x768
  resolution) supports 128x40, 128x54, and 128x96 16 color modes.  Select a
  resolution that best meets your requirements.
8.After you selection is made, choose the Save Changes option from the menu.
  Note  that when some high-resolution modes are selected, a message may
  appear asking for the drive letter of the floppy disk.  Before entering the
  drive letter, insert the disk that is requested in the floppy drive. After
  insert the disk, you may enter the drive letter containing that diskette.

   search for the LIBPATH statement and add
	"C:\OS2\DLL\CLDSP" 
   to the beginning of the LIBPATH statement.
   For example: 
	LIBPATH=C:\OS2\DLL\CLDSP; .; ........
	set video_devices=vio_SVGA
	set vio_SVGA=device(bvhvga,bvhsvga)
	device=C:\os2\mdos\vsvga.sys
   and remark (REM) the following statements:
	REM set video_devices=vio_vga
	REM set vio_vga=device(bvhvga)
	REM device=C:\os2\mdos\vvga.sys
2. Bring up a DOS full screen session, run CLMODE.EXE utility that came in
   your video adapter Utilities Disk to set monitor type, then insert CIRRUS
   LOGIC's driver diskette in drive A: or B:, type A:SVGA.EXE ON[Enter] or
   B:SVGA.EXE ON[Enter] to create an SVGADATA.PMI file. Copy your SVGADATA.PMI
   file to your OS/2 subdirectory.
3. Shut down the system to boot up from the OS/2 2.0 Installation Diskette,
   then ESC out of Diskette One to run CLI1620.CMD.

Installing the 256 colors accelerated driver:
256 color accelerated drivers can only be used with the OS/2 2.0 Corrective
Service Pack which is an upgrade that can be purchased from IBM and the
CIRRUS LOGIC GD5426 or GD5428 chips.
1. Edit OS/2's CONFIG.SYS file with the following settings add
   For example:	 
	set video_devices=vio_SVGA
	set vio_SVGA=device(bvhvga,bvhsvga)
	device=C:\os2\mdos\vsvga.sys
   and remark (REM) the following statements:

OS/2 2.1

The CIRRUS LOGIC OS/2 2.1 256 color accelerated driver supports CIRRUS LOGIC's
GD5426 or GD5428 chips.  For other CIRRUS LOGIC GD542X chips such as the
GD5424 you may use the 256 color driver that ships with OS/2 2.1 from IBM.

You will need the following programs for installation:  CLMODE.EXE or Video
Adapter Utility program to select monitor type.

IMPORTANT NOTE:
IBM's DISPINST.EXE calls SVGA.EXE to identify the SVGA chipset before
proceeding with the installation of a display driver. The IBM SVGA.EXE
shipped with OS/2 2.1 does not correctly ID the CIRRUS LOGIC Chipset. Running
CLINST21.CMD will update SVGA.EXE with the new CIRRUS SVGA.EXE before calling
DSPINSTL.EXE. This will help OS/2 identify the CIRRUS LOGIC Chipset correctly.
If you are having trouble installing the CIRRUS LOGIC Drivers, manually
rename the IBM SVGA.EXE to SVGA.IBM and copy the new SVGA.EXE The accelerated
drivers for OS/2 2.1 require 1MB of memory on the driver card.  If you have a
card with 512K of memory, use the standard drivers that shipped with your
copy of OS/2.

Install from floppy diskette:
1. Insert OS/2 display driver disk (must have volume labeled "DISP 1") into a
   floppy drive.
2. Invoke an OS/2 window session or an OS/2 full screen session.
3. Change to the floppy drive with the display driver disk, e.g. a:[Enter].
4. Run CLINST21.CMD from the floppy drive,
	e.g. clinst21 c[Enter].
5. Check the Primary Display check box from the DISPLAY DRIVER INSTALL dialog
   box.
6. Select CIRRUS LOGIC Blitter Driver from the PRIMARY DISPLAY ADAPTER TYPE
   dialog box.
7. The MONITOR CONFIGURATION/SELECTION UTILITY dialog box will appear. Click
   OK for default monitor settings (which is monitor type 3) or select Display

About Seamless Windows 3.0 support
Seamless Windows support is the ability to execute MS Windows 3.0 applications
in one or more windows on the OS/2 2.0 Workplace Shell Desktop, simultaneously
with OS/2 applications.  The Seamless Windows support that is provided in this
driver kit for the 256 color Windows driver runs with the 32-bit Presentation
Manager Display (PMD) driver 1.00b or later.  It requires OS/2 service pack
(XR06055) to be installed.  This Seamless Windows driver does not support
WIN-OS/2 3.1 that accompanies OS/2 2.1 beta.

Installation procedures:
1. Modify the SYSTEM.INI file in \os2\mdos\winos2 sub-directory.

Original		|	New
---             	|	--------
[boot]			|	[boot]
...			|       ...
			|
;driver for full screen Windows session   |
Change the display lines as shown below:  |
			|
display=vga.drv         |       display=256_1024.drv
			|
;driver for Seamless Windows session      |
sdisplay=swinvga.drv    |       sdisplay=256_768s.drv
Add these lines to the bottom of the SYSTEM.INI file as shown below:
[CLVGA]
cursor=1
dpi=96
videomode=96    ; 1024x768x256
;videomode=92   ; 800x600x256
;videomode=95   ; 640x480x256

   When selecting a video mode to run in Win3.0\OS/2 2.0 Program Manager you
   must select the same resolution you are running in OS/2 Presentation Manager.
   For example, if you are running 640 x 480 x 256 color OS/2 Presentation
   Manager, you must also use 640 x 480 x 256 color for Win 3.0\OS/2 2.0. 
3. Invoke 'Migrate Applications' from the 'System Setup' folder to install MS
   Windows applications on the Workplace Shell desktop.  The MS Windows
   applications will be placed in the 'Windows Programs' and the 'Additional
   Windows Programs' folders.
4. Double click on an MS Windows icon to run in Seamless Windows mode.
   Note : Support for Seamless SetRES is not available. You still need to go
