Easy installation
-----------------
The  installation  utility  is  provided  to  facilitate the
smooth  installation  of  the  display  drivers  and utility
software. The installation program is menu-driven and allows
you to select and install  only  those  display  drivers for
software and applications currently in use.

It  is  important  to note that some display drivers need to
have  the  associated  vendor's  application program already
installed  on  the  system prior to loading the Cirrus Logic
VGA  display  drivers.  In  other  cases, the loading of the
display  driver  may  be  an  integral  part of the vendor's
product  installation  process.  Please  review  the  driver
product  section  below  for  specific instructions prior to
running the installation program.

The  installation utility is located on the diskette labeled
Disk  1.  To   install   the  desired  display  drivers  and
utilities,  insert  the  diskette  into  the  1.44MB  floppy
Drive, type

                    INSTALL[Enter]

Follow  the instructions on the screen to install the listed
display  drivers.  At  any time you may press [Esc] to abort
the installation process and go back to DOS.

Selected drivers are simply copied to the specified disk and
directory.  Applications may require additional installation
as  described in the Display drivers section of this manual.






Cirrus Logic BBS
----------------
If  there  are  any  newer versions of the software provided
with your VGA adapter, they will be available  on the Cirrus
Logic BBS. It is a WILDCAT! BBS. The  phone  number is (510)
226-2365. It can handle modems  running up to 9600 baud. The
modem should be set  to NO parity,  8 data bits, 1 stop bit.
Before you are able  to download software, you must join the
conference(s) for the product(s) that you are interested in.

Utility software
----------------
Several  utility programs are supplied with you Cirrus Logic
VGA. The following section describes these utilities and how
to use them.

Clmode  is  a program supplied with your Cirrus Logic VGA to
configure it's various options.

SetRES lets the user change the operating resolution and the
number of colors from within Windows.


Clmode
------
The  Clmode  utility  allows  the user to define the type of
monitor  attached  and  set the video modes supported by the
Cirrus Logic VGA.


Using Clmode's menu-driven interface
------------------------------------
At the DOS prompt type:

                        CLMODE[Enter]

The main  popup window consists of a number of buttons. Each
button represents a different option or menu. The underlined
letter  of a  button  name specifies the hot key combination
for  that  item.  For  example,  press  the  [Alt]  and  the
underlined letter keys simultaneously or just the underlined
letter key to select an option.  Note if you intend to use a
mouse  with  Clmode,  then  a  mouse  driver should first be
installed prior to running the Clmode utility.


Choosing the attached monitor type
----------------------------------
Selecting  the  proper  monitor  type  will allow the Cirrus
Logic  VGA  to display the highest quality output that it is
capable  of  with  the  attached  monitor.  The monitor type
determines  what  video  modes  will  be  available  to your
system.  It  will  also determine the vertical refresh rates
available. Generally, the higher the refresh, the better the
screen  will  look.  A  description of the available monitor
types is given in table 2 at the end of this section.

Select  the  Monitor  Type button.  The  Monitor  Type setup
window  will  be displayed. The current monitor type will be
highlighted  initially.  Use the cursor keys or the mouse to
choose  the type of monitor attached. Selecting the Advanced
monitor  type  will  enable  you  to  customize  the monitor
timings for the monitor you are using.


                                                      Page 3

To customize  the  monitor timings, use the mouse or the tab
key  to select the gray Set Advanced button. It will only be
available  if  the  Advanced  monitor type is selected. This
will bring up a new dialog box with drop down menus for each
available  resolution.  Select  the desired refresh rate for
each  resolution.  Consult  the  manual  for your monitor to
discover  the  correct  rate.  When  all of the settings are
correct,  select the OK button. If there are any problems or
you change your mind, select the Cancel button.

Before saving  the  new monitor type, you may want to select
the Verify button to view each of the new video timings that
you  have  selected  to verify that they are compatible with
your  monitor.  After  each  test screen is displayed, press
[Enter] or the left mouse button to see the next video mode.
If there is a problem, press [Esc] or the right mouse button
will return you to the Monitor  Type Setup dialog box. Try a
slower setting for the resolution  that did not work and try
verifying your choices again.

Once you are sure that everything is correct, press the Save
button  to set the new monitor type. Press the Cancel button
to discard  any  changes.  Press  the  Help  button to get a
detailed  explanation  on  the  monitor  types  and  the VGA
refresh rates.

On some systems the monitor type will be remembered from one
session to the next. To test this, select a monitor type and
exit  the  Clmode  program.  Turn  the  computer off for ten
seconds. After rebooting the computer, run Clmode and verify
whether  or  not  the  monitor  that  you  selected is still
enabled.  If  it is, it should not ever need to be set again
in  normal  use.  If  the monitor type was not kept then you
should  select  the  option  to have Clmode save the monitor
type in you AUTOEXEC.BAT file. You will be given this choice
after selecting the Save button.



Available video modes
---------------------
Select the Video Mode button. The Video Mode Preview  window
displays  all  the  modes supported according to the monitor
type  attached  and the amount of video memory present. This
list  of  video  modes  will tell you which are available in
your  current configuration for use with extended resolution
drivers. To see what different video modes look like on your
monitor,  select  the Preview button. After each test screen
is displayed, press  [Enter] or the left mouse button to see
the next video mode. If you don't want to see any more video
modes press [Esc] or  the right mouse button will return you
to the Video Modes Preview window.


                                                      Page 4
Retrieving the current VGA controller status
--------------------------------------------
The  information  in  the  main  window  displays   the  VGA
controller type,  the  BIOS version number and the amount of
video memory present.


Getting help
------------
Clmode provides Help  for the following items: Monitor Type,
Video  Mode  Preview,  Mouse, Keyboard and About Clmode. The
Monitor Type help window explains the different capabilities
of each monitor type. The Video Mode help window defines the
information given in the Video Mode window. The Keyboard and
Mouse  help  windows explain how to use the keyboard and the
mouse  to  make  selections.  The  About window displays the
Cirrus  Logic  copyright  message  and  the  Clmode  version
number.


Exiting the Clmode
------------------
To  exit  Clmode  at  any  time,  press  [Alt] and [F4] keys
simultaneously, or click the left mouse button on the system
button  of  the main window (i.e. The top left corner button
of the  window  which is shown as a dot), or select the Exit
button.  When  the  Clmode  utility exits, the current video
mode, monitor type, and VGA refresh rate will be displayed.


Using Clmode's command line options
-----------------------------------
When  command  line  options for CLMODE.EXE are given at the
DOS  prompt,  the menu-driven windows will not be displayed.
Instead,  monitor type,  video mode and refresh rate will be
set  at  the  DOS  prompt.  The  command  line  options  for
CLMODE.EXE are:

CLMODE [[modenum][+*-]] [m[montype] | t6=x t8=x t1=x t2=x]
[modenum]    mode number
[+*-]        + selects 400 lines (default)
             * selects 350 lines
             - selects 200 lines
[montype]    monitor type
t6=x(Hz)     640x480   @ (0 = 60, 1 = 72)
t8=x(Hz)     800x600   @ (0 = 56, 1 = 60, 2 = 72)
t1=x(Hz)     1024x768  @ (0 = 87i, 1 = 60, 2 = 70, 3 = 72)
t2=x(Hz)     1280x1024 @ (0 = 87i, 1 = Not available)

For  example,  to  select  mode  3  for a Super VGA  monitor
(montype 2), type the following command at the DOS prompt:

                CLMODE 3+ m2[Enter]


                                                      Page 5

To  select  custom  monitor timings with 640x480 at 60Hz and
800x600 at 72Hz refresh type:

                CLMODE t6=0 t8=2[Enter]

Typing an invalid  option will display the command line help
text.  Typing  [S] as a command line option will display the
current Clmode settings.

Following is a table of common monitor types.

SetRES
------
SetRES  is  a utility that runs under Windows 3.x. It allows
the  user  to change the screen resolution, number of screen
colors,  and  select either large or normal fonts and system
resources.

After  new  options  have been selected, the user can either
immediately   restart   Windows,  in   which  case  the  new
resolution will take effect immediately, or continue working
in  the current resolution, in which case the new resolution
will take effect the next time Windows is started. Note that
under  Windows  3.0  large  and normal font selection is not
allowed.

This  application assumes that the Windows drivers have been
correctly configured using Windows Setup. For information on
installing  and  configuring  Windows  display drivers using
setup, please refer to the Microsoft Windows section in this
manual. From  Windows  Setup  select  the   Multi-Resolution
entry. This will correctly configure the  driver for Windows
386 enhanced mode operation, and  copy  the  necessary  font
files to your hard disk.


Installation
------------
[] Start Windows.

[] In the Program Manager, choose File Run.

   Specify the diskette drive where the Windows Drivers  and
   Utilities  Diskette  is  inserted,  and  run  the install
   program. For  instance if the floppy is in drive A:, type

                A:\INSTALL[Enter]

[] When  prompted,  specify to copy the files to the Windows
   directory.

SetRES may now be run by selecting the SetRES icon.

Display drivers
---------------
The  Cirrus  Logic  video controller is 100% VGA compatible.
The display drivers described in this manual are supplied to
improve the resolution for each supported software
application package.

It  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 display drivers directly to the appropriate application
directories  where they may 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.

        Cirrus 54xx v1.3, Multi-res 256 colors

Highlight  the  correct  choice  by moving the cursor to the
desired display driver, and then press [Enter].

[] When  Windows  Setup  asks you to insert the Cirrus Logic
   GD54xx Windows 3.x Fonts Diskette, Leave the same disk in
   the drive and enter the same disk drive as you did above,
   but  instead reference the system directory. For example,
   type the following: A:\SYSTEM[Enter]

Later  you  will  be asked to insert the Cirrus Logic GD54xx
Windows  3.0  Driver  Diskette,  This  time  use  the  WIN30
directory. For example, type the following:

        A:\WIN30[Enter].

Setup will complete the installation.


Configuring the drivers for Windows 3.0
---------------------------------------
The  GD54xx  Multi-Resolution  color drivers  require that a
section be present in your SYSTEM.INI  file. The Windows 3.0
setup   program   must   be  used  to   select  the  default
configuration of the 16 or 256 color  drivers. After exiting
the Setup, edit the SYSTEM.INI file to change the resolution
manually. Any text editor  may  be used, including Edlin, or
Edit that came with your version of DOS, or Notepad found in
the accessories group of your Windows 3.0 installation. Find
the section [CLVGA]. The [CLVGA] section will not exist when
you  first setup Windows 3.0. You must add one to the end of
the  SYSTEM.INI  file.  Type in the appropriate section from
the following table.

Resolution    16 color drivers          256 color drivers
------------------------------------------------------------
640x480       [CLVGA]VIDEOMODE=18       [CLVGA]VIDEOMODE=95

You  will  find that it is easiest to use the SetRES utility
that  comes  with   your   Cirrus  Logic  VGA  to  configure
resolutions and color selections. Run the install utility on
the  Windows  driver disk to copy the drivers and the SetRES
utility  to  your hard drive (see the SetRES section of this
manual).  Then  run  SetRes from within Windows to configure
your installation.

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:

[] To speed up AutoCAD REDRAWs, PANs, and ZOOMs

[] 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
AutoCAD's 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:

[] 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.

[] 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.

[] TurboDLDClassic  gives  you  numerous  new user-interface
   features,  such as the bird's eye view. (via the features
   described later in this manual).



                                                     Page 13

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.



Features
--------
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.




                                                     Page 14
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.






                                                     Page 15
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 t he Do you want to select... message to display
the available video options for AutoCAD.

Select  TurboDLDClassic   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).

                                                     Page 16

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.


                                                     Page 17

*  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.

                                                     Page 18

*  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.

                                                     Page 19

   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  wit h 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.



                                                     Page 20
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 video driver ... 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.




                                                     Page 21
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 don't 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),

                                                     Page 22

make sure  to tell AutoShade this. A single monitor approach
will  require  a  redraw  of  the  display  screen  after  a
rendering screen.

Next,  follow t he same installation steps that were used to
select   the   graphics  board  and  display  and  rendering
resolutions for AutoCAD.


3D Studio
---------
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

                                                     Page 23

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.

[] 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.



                                                     Page 24

[] 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
   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 of at least 256
   colors. Otherwise, AVE Render  will not allow a render to
   viewport selection.

[] 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

                                                     Page 25

   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

                                                     Page 26

   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

                                                     Page 27

   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.

[] Don't   Accidentally  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  can't  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.




                                                     Page 28

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 you're 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 haven't
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   you're  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 can't 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

                                                     Page 29

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.









                                                     Page 30
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








                                                     Page 31
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.




                                                     Page 32
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 doesn't affect the amount of disk access it's  probably
time to add more memory to your system. Contact your AutoCAD
dealer for assistance in upgrading your memory.

Regarding  display  list  memory,  it's 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

                                                     Page 33

(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 don't 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.





                                                     Page 34
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

                                                     Page 35

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 AutoCAD's
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  don't use any
display  list  processing  to  speed  themselves up. One way
around  this problem is to use another of AutoCAD's 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  you've  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 AutoCAD's 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

                                                     Page 36

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.

GEM/3
-----

Installing GEM/3 display drivers
--------------------------------
To install  the GEM drivers the first step is to build a GEM
driver pak.

[] In the  following three steps, you create a disk known as
   the  GEM  DRIVER  PAK.   Using  the  standard  DOS FORMAT
   utility, format a blank diskette by inserting it in drive
   A and typing the following:

                FORMAT A: /V [Enter]

   The  DOS  format utility will then prompt for the  volume
   label by displaying:

   Volume Label? (11 characters max) Press Enter for none.

   At this  prompt,  type the following volume-label name in
   upper case:

                GEM DRIVRPK [Enter]

[] Using the DOS COPY utility, copy the following files from
   the  GEM/3  system  master diskette (comes with GEM/3) to
   the   newly  formatted  GEM  DRIVRPK  diskette.  Type the
   following  sample commands assuming that the GEM/3 system
   master  diskette  is  in  drive A:  and  the  GEM DRIVRPK
   diskette is in drive B:

                COPY A:GEMVDI.EXE B: [Enter]
                COPY A:MDGEM?.SYS B: [Enter]

[] Insert the  Cirrus  Logic drivers diskette into Drive A:.
   Run the  Cirrus Logic installation program (INSTALL.EXE),
   and choose  the  option for the GEM/3 drivers and specify
   the  drive  and  directory  where you want them copied to
   (such as B:\).   GEM/3   requires  that  the  drivers  be
   installed  from  the  root  directory of a floppy disk in
   drive A:.  Be  sure to install the drivers to the root of
   drive A:  or  drive  B:  and  then  place the diskette in
   drive A: before proceeding. Install GEM/3 (following  the
   instructions provided in the product's manual), selecting
   the standard IBM VGA Color(IBM PS/2) driver.

[] After  successfully  completing  installation, insert the
   GEM/3 System Master Disk in drive A.

[] Move to drive A by typing A:[Enter]. Please note that you
   must install from the A: drive.

[] Then type GEMSETUP[Enter].

                                                     Page 39

Follow the GEM/3 installation  instructions up to the CHANGE
EXISTING  CONFIGURATION  stage.  When  prompted for a screen
driver choice, highlight:

                OTHER (DRIVER PACK)

[] When  prompted to  insert  a  screen driver into drive A,
   insert the newly created GEM DRIVRPK diskette.

[] Select one of the following:

        Cirrus Logic VGA 16 Color 800x600
        Cirrus Logic VGA 16 Color 1024x768

[] Continue with the remainder of the installation.

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

To install a Lotus display driver, proceed as follows:

[] Run  the Cirrus Logic installation program (INSTALL.EXE),
   and choose  the  option  for  the  Lotus 123 and Symphony
   drivers  and  specify  the  drive and directory where you
   want them copied to (such as C:\LOTUS).

[] From within the Lotus sub-directory type:

                INSTALL [Enter]

[] From the next menu, select Advanced Options for Lotus 123
   v2.2 or Change Selected Equipment for Lotus 123 v2.3.

[] For  v2.2,  select  Add  New Drivers to Library and go to
   step 3. For v2.3, select Modify Current Driver Set and go
   to step 6.

[] From the next menu, select Modify Current Driver Set.

[] From  the  next  menu,  select  one  of  the  display and
   resolution configurations.

[] From the next menu, select Return To Menu.

[] From the next menu, select Save Changes.

[] Enter  the  name you have selected for the driver set. We
   recommend that the driver set name reflect or include the
   driver's   resolution  (e.g. 132x43)  NOTE:  The  default
   driver set name assigned by the program is 123.SET.

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 123 v3.X
--------------
To  install  a  Lotus  3.0 or 3.1 display driver, proceed as
follows:

[] It  is  assumed  that  Lotus 1-2-3 v3.0 or 3.1 is already
   installed  on  your  hard  disk, using the standard 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]

[] 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]

[] Run  the Cirrus Logic installation program (INSTALL.EXE),
   and choose  the  option for the version of Lotus 123 that
   you  are  using 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 file  (see step 2
   above), answer YES to  the  prompt to confirm overwriting
   the file.

[] Now run the Lotus installation utility by typing:

                INSTALL[Enter]

[] 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.

[] Select  Modify  Current  DCF,  or  Choose  another DCF to
   modify,  according  to  your  preference.  The  following
   procedure is valid for either selection.

[] 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.  GD54xx 100
   Column  Display (800 x 600 resolution) supports 100 x 31,
   100 x 42, and 100 x 75 16 color modes. GD54xx 128  Column
   Display  (1024 x 768   resolution)  supports    128 x 40,
   128 x 54,   and  128 x 96  16  color  modes.   Select   a
   resolution that best meets your requirements.


                                                     Page 42

[] 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 inserting the disk, you may enter the
   drive letter containing that diskette.
