Section 1.... Installation
============================================================

Your SVGAP1 product ships with two driver diskettes.

WINDOWS  INSTALL  DISK.  This  diskette contains drivers for 
     MS-Windows 3.1 and many popular DOS applications. There 
     is an installation  utility  'SETUP'  that  runs  under
     Windows.   This  utility  installs drivers for both DOS 
     and Windows applications.

     Windows NT is included on the 'DOS Install Disk'

DOS INSTALL DISK. This diskette contains  drivers  for  many 
    popular  DOS  applications.  There  is  an  installation 
    utility 'INSTALL' that runs under DOS. This installs the 
    same drivers for DOS applications as the Windows Install 
    Disk.


If you have Microsoft Windows, use the WINDOWS INSTALL DISK. 
If  you  do  not have Microsoft Windows, use the DOS INSTALL 
DISK.

There is no need to use BOTH diskettes!



If you are installing drivers under  DOS,  go  to  the  next 
section. If you use Microsoft Windows 3.1, start here.


==================================
INSTALLING UNDER MICROSOFT WINDOWS
==================================


1.  Make  sure  that  Windows  3.1  is  installed. Using the 
Windows Setup Program, (described below) select VGA  as  the 
Windows  display type. Verify that Windows will run with the 
standard VGA display. If there  are  any  problems,  correct 
them  now  before  attempting  to  install  the  new Windows 
drivers.

Running Setup
-------------

Note:  for  complete  information  on  using  Windows  Setup 
utility, consult your Windows Manual.

1. Go to your 'Windows' directory.  (Typically  C:\Windows). 
   For  information  on  how to change directories, see your 
   DOS command reference for the command 'CD' or 'CHDIR'. 2. 
   Type in SETUP [then the ENTER key].  3.  Use  the  cursor 
   arrows to highlight the DISPLAY option. Then press ENTER. 
   4.  From  the  list  of available display drivers, select 
   VGA. Then press ENTER. 5. Press  ENTER  again  to  select 
   'Accept  Configuration  as  shown  above'. 6. Press ENTER 
   again to select 'Current Driver'.

Windows will now use the STANDARD VGA display  driver.  This 
will   allow   you  to  start  Windows,  and  then  continue 
installing the SVGAP1 driver using Windows.


2. Start Windows as you normally do. When you  have  Windows 
   running,   insert   the   'SVGAP1   Windows  Installation 
   Diskette' into your A: or B:  as  appropriate.  From  the 
   Program  Manager Main Menu, Select File|Run. Then type A:
   \SETUP or B:\SETUP (as appropriate) and click OK.

3. After initialization, a SVGAP1  backdrop  screen  appears 
   followed by a list of setup options.

The default selections are Windows 3.1 Drivers/Utilities and 
SVGAP1  Utilities.  Make any additional selections and click 
OK.

4. For each selection made, the Setup program will  ask  you 
   for  the  directory  name of each application. Setup will 
   suggest a 'default' directory name. Use  the  default  or 
   change it, then select OK.

5.  The  SETUP  program will copy all necessary files to the 
   chosen subdirectories. Follow all on-screen directions.

6. Once you have  installed  the  display  drivers  to  your 
   Windows  directory,  you  will  need to select one of the 
   drivers by using the following method:

Use the  WINMODE  utility.  Documentation  for  the  WINMODE 
utility is provided later in this file. 



===========================
Installing Drivers with DOS
===========================

1. Insert  the DOS installation  diskette in your A: (or B:) 
   diskette drive and type A:INSTALL (or B:INSTALL).

2. Read  the  introductory  screen  and  press  any  key  to 
   continue.

3. Next, you are  asked to indicate the drive where you wish
   to install the selected driver(s).

4. You are presented with a list  of  drivers  for  selected
   popular  applications.  Follow  on-screen  directions and 
   make you selection(s) with the SPACE BAR.


5. The  installation  program  will  suggest a subdirectory. 
   Accept it  or  change  it  and  press  [ENTER].  You  are 
   notified when the installation is complete. Press any key 
   to exit to DOS.



============================================================
Section 2.... Utility software
============================================================

There  are  utility  programs  which  are supplied with your 
SVGAP1.  The following section describes these utilities and 
how to use them.

CLMode is a program supplied with your SVGAP1  to  configure 
it's various options.

The TSRFONT utility will make a full 8x14 size character set 
available to programs that bypass the BIOS and directly draw 
characters to the screen.

WinMode lets the user change the  operating  resolution  and 
the  number  of  colors from within Windows.  Information on 
WinMode can be found in the Windows 3.1 section.

============================================================ 
Section 3..... CLMode & Center 
============================================================ 

CLMode  
------

The  CLMode utility allows the user to configure the 
panel options, define the type of monitor attached, and  set 
the video modes supported by the SVGAP1.

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 that to use 
a mouse, a mouse driver should be installed prior to running 
the CLMode utility in order to use  the  mouse  pointer  for 
button selection.

Choosing the attached monitor type
----------------------------------

Selecting  the  proper monitor type will allow the SVGAP1 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.

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.

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  your  AUTOEXEC.BAT  file.  You  will be given this 
choice after selecting the Save button.


Available video modes
---------------------

Select the Video  Modes  button.  The  Video  Modes  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.

Centering adjust
----------------

Centering is available while in Video  Modes  Preview  (only 
for  extended  Graphics  modes  58h  and greater).  While in 
Preview, you have the option to use  the  Right/Left/Up/Down 
arrow  keys  to  adjust your screen accordingly.  The screen 
adjustments have predefined limits, and in some  cases,  the 
limit for the right side adjustment for some modes will have 
already  been  reached  when  entering the Preview mode.  In 
that case, no right side adjustment will be allowed.  Once a 
mode has been adjusted, the new values for horizontal and/or 
vertical positioning are saved within CLMode.  When  exiting 
from  CLMode,  you  are prompted on whether you want to save 
these new parameters to TSR (CENTER.COM). If you  choose  to 
do  this,  the  values to be used for the adjusted modes are 
stored in CENTER.COM on exit.  CENTER.COM can then be loaded 
outside of CLMode.  Once this is accomplished, all the modes 
which you have adjusted will be the active  modes  set  when 
that  mode  request  is made. To unload CENTER.COM, you must 
change the MONITOR TYPE currently set in CLMode.  This  will 
unload  CENTER.COM  and  uninstall all centering adjustments 
previously redefined.  To save new centering adjustments for 
a different MONITOR TYPE,  repeat  the  above  procedure  as 
before. Your new adjustments will be written into CENTER.COM 
over the previously defined adjustments.

An additional adjustment for monitor SYNC POLARITY  is  also 
available while centering is active.  To adjust the polarity 
of  the  current  mode,  simply  press the PgUp or PgDn keys 
(while in Preview) to cycle through the  available  options, 
(Vertical Sync Polarity/Horizontal Sync Polarity):

	+/+, +/-, -/+, -/-

Note:  Centering  will not be allowed if CENTER.COM has been 
       loaded.  You must unload CENTER.COM before attempting 
       to save new adjustments.

Limitations: You may only adjust and save 16 modes at a time 
	     to CENTER.COM.

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:  Configuration,  Monitor  Type, Video 
Modes, Mouse, Keyboard and About CLMode.  The  Configuration 
help  window  explains the flat panel configuration options. 
The  Monitor  Type  help  window  explains   the   different 
capabilities of each monitor type.

The Video Modes 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 copyright message 
and the CLMode version number. Exiting the  CLMode  To  exit 
CLMode   at   any  time,  press  the  [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, configuration, monitor type, video mode and refresh 
rate  will  be  set  at  the  DOS  prompt.  The command line 
options for CLMODE.EXE are listed below:

   CLMODE {modenum} {m{montype} | {s n} }[Enter]

   Where:  {modenum}    mode number
           {montype}    monitor type Valid monitor types:
                        0  VGA
                        1  8514
                        2  Super VGA
                        3  Extended Super VGA
                        4  Multifrequency
                        5  Extended Multifrequency
                        6  Super Multifrequency
                        7  Extended Super Multifrequency
           {montype}    monitor
                        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)
                        t2=x(Hz)    1280x1024 @ (0 = 87i, 1 = Not available)
                        s           List status information.

For example, to set video mode 3:

               CLMODE 3 [Enter]

For example, 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. Typing an invalid mode will display 
the supported video modes. Typing H will display help



============================================================
Section 4.....TSRFONT driver
============================================================

Some DOS application programs bypass the BIOS  and  directly 
draw characters to the screen.  Programs which directly draw 
characters  using the 8x14 font from the BIOS will appear to 
be writing incorrect data to the screen.  Typically this can 
occur in programs which offer a selection to use a  graphics 
25  or  34  line display mode.  Other programs may appear to 
cut off the descenders of characters like "y" and "j".

Running the TSRFONT  driver  will  make  a  full  8x14  size 
character  set  available  to  these  programs,  and  should 
correct  display  errors discussed above which were observed 
in these programs.

To run the TSRFONT driver, type  TSRFONT  [Enter].   If  you 
want to run it automatically when you turn on your computer, 
add it to your AUTOEXEC.BAT file.

============================================================
Section 5......Microsoft Windows 3.1
============================================================

The  Windows  3.1  driver installation utility copies all of 
the graphics driver and utility files to your hard disk.  It 
also  allows  you  to  configure  your  graphics  system for 
Windows 3.1 in either DOS or OS/2 v2.1. You can  change  the 
monitor  refresh  rates,  resolution,  number  of  available 
colors,  large  or  normal  size  fonts and font cache  size
using the WINMODE utilitiy installed to the SVGAP1 Utilities
group.


After  new  options  have  been  selected,  you  can  either 
immediately  restart  Windows,  in  which   case   the   new 
configuration  will  take  effect  immediately,  or  you can 
continue working in the current resolution,  in  which  case 
the new resolution will take effect the next time Windows is 
started.  In some configurations the AUTOEXEC.BAT file needs 
to be modified to make the changes permanent.



============================================================
Section 6......Windows NT
============================================================

Windows NT display drivers installation:

1.  Start Windows NT.

2.  From the MAIN window of  the  Program  Manager  run  the 
    Windows NT Setup program.

    the list of available display drivers.





============================================================
Section 7.....Autodesk - ADI 4.2
============================================================
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.

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 
adapter 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  the  most  closely 
approximate 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. 
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.

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..  If you are 
reconfiguring AutoCAD, and currently have a  drawing  loaded 
you must exit the drawing, and reload the drawing.


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 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), 
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 release 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 
GRAPHIC  DRIVER  CONFIGURATION.  Follow the Vibrant Graphics 
Configuration Program Setup 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  categories  set  RCPADI. 
When  Vibrant Graphic settings are complete click OK to exit 
and save settings.  The Setup for Turbodld  Classic  Drivers 
will  then  commence.  Follow the menus to Setup Display and 
Rendering Screen.  Save and Exit to 3D Studio.  Please  note 
that  the  out  of  the box drivers that are supported in 3D 
Studio release 3.X are supplied and maintained by  Autodesk. 
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 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 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. 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.  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 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  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 
(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.

============================================================
Section 9........Lotus 123 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 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]

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) Install the drivers to your lotus directory as  described 
in the beginning of this document, 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.

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. GD543X 100 Column 
Display  (800x600  resolution)  supports 100x31, 100x42, and 
100x75 16 color modes. GD543X 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 inserting the disk, you  may  enter  the  drive 
letter containing that diskette.


============================================================
Section 10........Installing Word drivers
============================================================

To  install  the  Word  high resolution text driver supplied 
with your SVGAPCI VGA, follow  these  instructions:  If  you 
have  not  already done so, install Microsoft Word onto your 
computer system. Follow the instructions supplied with Word.

When asked for a  screen  display  type,  choose  IBM  Video 
Graphics   Array   (VGA).   Run   the  installation  program 
(described earlier), and choose the option for the Microsoft 
Word drivers and specify the drive and directory  where  you 
want them copied to (such as C:\WORD5).

To  use  the  new drivers they must be installed in the same 
directory as Word. Otherwise, they must  be  copied  to  the 
Word directory before they can be used.

INSTALL.EXE  will copy two screen drivers: SCREEN8.VID - for 
800x600 graphics  resolution  SCREEN.VID  -  for  1024  x768 
graphics resolution

The  driver to be used must be named SCREEN.VID. When a file
is renamed this, it  will  overwrite  the  existing  display 
driver.

If  you  wish to preserve the original, it should be renamed 
or copied prior to installation of the new drivers. The  new 
driver  is  now  installed,  and  to use it, run Word as you 
normally would. To view and change the  screen  resolutions, 
select  Options,  move the cursor to display mode, and press 
[F1]. Choose the desired screen  resolution  from  the  list 
presented.  A  sub-menu will appear, listing all the choices 
of resolutions supported by  the  text  driver.  Select  the

Section 12......Power management screen saver
============================================================

Power management screen saver

About the screen saver
----------------------  


The  Display  Power  Manager  for  Windows  3.1  provides  a 
mechanism  to  control  the  amount  of  power  used  by   a 
computer's  monitor.   It  provides  a  total of 5 levels of 
power savings. 


The screen saver is installed when you install  the  drivers 
and  select  'Windows  3.1  Drivers'. To activate the screen 
saver, select the 'desktop' icon in the  CONTROL  PANEL  and 
select 'Power Management Screen Saver' as the current screen 
saver.


The first level is a conventional screen  saver  that  turns 
the  screen  black  with  the  SVGAP1 Logo. The black screen 
provides substantial power savings and  the  logo  lets  you 
know that the computer is still active. 


The  other  four  levels  of power savings are... 

Reduced  on  mode  -  Reduced  on  mode is an optional power 
saving state that allows the  computer  to  use  some  power 
savings  while  still  fully  operational. Currently this is 
limited to some portable computers that can lower the  power 
usage  on  their LCD displays.  This causes some degradation 
of display quality. 


Stand by mode - Stand by mode is an  optional  power  saving 
state  that  gives  minimal  power savings, but provides the 
fastest recovery time. It is enabled by blanking the  screen 
and  lowering  the  horizontal  rate to less than 10 Hz with 
less than a 25% duty cycle.  There is no change to  vertical 
timing.  


Suspend  mode  -  Suspend mode is a mandatory state in which 
substantial power savings are achieved by the display.   The 
trade  off is that recovery times are longer than from stand 
by mode.  It is enabled by blanking the screen and  lowering 
the  vertical  rate  to less than 10 Hz with less than a 25% 
duty cycle.  There is no change to horizontal timing. 


Off mode - Off mode provides  the  highest  level  of  power 
savings  and the longest recovery times.  With this mode the 
display is actually turned off so that  recovery  times  are 
equivalent  to  switching  the  monitor on. It is enabled by 
blanking the screen and lowering  both  the  horizontal  and 
vertical  rates to less than 10 Hz with less than a 25% duty 
cycle.  

They match the power saving modes defined by the VESA VBE/PM 
(see below) standard. As you move down from one mode to  the 
next,  the amount of power being saved is greater, but so is 
the amount of time that it takes for a  monitor  to  recover 
and  be  ready  to display data. The screen saver will cycle 
through all of the selected power  saving  modes  one  after 
another  until  the  maximum  selected power saving mode has 
been reached.  The number of minutes that is  specified  for 
each  level is the number of minutes after the previous mode 
has been enabled.  It is not the total time before  entering 
that mode.  


If  the  password checkbox is enabled, then the screen saver 
will prompt the user for a password  before  it  quits.  The 
password  is the same one that is used for other Windows 3.1 
screen savers. 


The Energy Star program Energy Star is a program created  by 
the  EPA  to  promote  energy  efficiency.  The goal of this 
program is to lower electricity usage  by  making  computers 
and   related  hardware  more  energy  efficient.  Computers 
currently use an  estimated  5%  of  commercial  electricity 
consumption.   If  no  actions are taken, this could rise to 
10% by the year 2000. Ironically, much of  this  electricity 
is  wasted.   Research  shows that the vast majority of time 
personal computers are on, they are  not  actively  in  use. 
Additionally  30%  -  40%  are  left running at night and on 
weekends.  Electricity generation accounts for  35%  of  all 
U.S.   emissions  of  carbon  dioxide  -  the most prevalent 
greenhouse gas.  It also accounts for 75%  and  38%  of  all 
U.S.    emissions  of  sulfur  dioxide  of  nitrogen  oxides 
respectively - the two pollutants most responsible for  acid 
rain.   

By  using  more  energy-efficient  equipment  in  our homes, 
offices and factories, we can reduce this pollution -  while 
saving   money.  The  Energy  Star  logo  is  used  to  mark 
computers, peripherals and software that  have  adopted  the 
EPAs power saving guidelines.
