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 A: drive, type 
A:[Enter] 
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.
Installation
Installing the Cirrus Logic VGA adapter
To install the Cirrus Logic VGA, you may need some or all of the following tools:
a medium size flat blade screwdriver,
a medium sized phillips head screwdriver,
a 3/16 inch nutdriver or wrench.
Preparation
The Cirrus Logic VGA adapter may or may not be shipped with the zero-wait-state jumper installed. If so, the zero-wait-state jumper will be set to not assert the zero-wait-state line. You may achieve better performance in some systems by installing this jumper. If any problems are encountered with zero-wait-state enabled, remove the jumper to disable this feature.
PC, XT and compatible users
The Cirrus Logic VGA card requires a 16-bit expansion slot. Therefore the VGA card is not compatible with PC, XT and other 8-bit compatible systems.
IBM AT and AT compatible system users
The IBM AT, IBM XT-286 and compatible computers use a program typically called Setup to tell the computer what equipment is installed in your system. The Setup program is usually part of the package of programs provided with your AT or AT compatible computer. The Guide To Operations (or equivalent manual) will explain the use of the Setup program. After the VGA adapter is installed, Setup will need to be run to configure the computer for proper operation with the Cirrus Logic VGA card.

Open the computer system
Before opening the system, be sure that the power to the computer system unit and all devices connected to it is off. Disconnect the cables from the back of the system in order to give more room to work. Note how all of the cables are connected prior to disconnection.
In a typical IBM AT compatible computer all cover mounting screws are located on the back of the computer. Remove these screws.
Carefully remove the cover. On most computers the cover will slide forward or backward, or tilt off.
Choose an expansion slot for the Cirrus Logic VGA adapter card.
Your VGA adapter must use a 16-bit expansion slot. Do not insert it into an 8-bit slot.
Installing the VGA adapter in your computer
Check that the power is turned off.
If necessary, remove a system expansion slot cover by removing its retaining screw and lifting it out. Save the screw.
Hold the Cirrus Logic VGA adapter by its top corners and slide it into the system unit. Make sure that it is correctly seated in the expansion slot.
Secure the VGA card with the screw that you removed in the step above.
Are the computer system's switches and jumpers correctly set? Check the user's manual for your computer for any additional configuration instructions.
Replace and secure the system cover.
Plug a VGA compatible or multi-frequency display into the 15 pin 'D' shaped video connector at the back of the Cirrus Logic VGA adapter.
If you are using a multi-frequency monitor, you may need a special 15 pin PS/2 compatible adapter cable, and you will need to make sure that your multi-frequency monitor is configured properly for a PS/2 compatible analog VGA signal. Some multi-frequency displays have a switch to select 'TTL' or 'analog' operation; set this switch for 'analog'. Check the manual that came with your monitor for additional information on configuring it.
IBM AT and AT compatible users
After the VGA card is installed in the AT compatible system, use the Setup program supplied with the system to tell the computer about the equipment installed. When using AT and compatible Setup programs with the Cirrus Logic VGA adapter, please follow these steps.
Run Setup to configure the computer. Sometimes this utility comes on a disk, sometimes it is built into your system's ROM BIOS. When you arrive at the part of the program where video support is specified, the program may ask you if the monitor you are looking at will be the primary monitor, answer yes. If you are presented with a list of video options, select the option for VGA .
If no option for VGA is listed, select support for EGA. The Cirrus Logic VGA adapter will look to many systems like an EGA card. If you don't see an option for EGA, try the option for NO MONITOR, RESERVED or SPECIAL. These will usually work. If not, see your equipment dealer. At the conclusion of the Setup program, the computer will restart as if you had just turned on the power.
Operation
If you have followed the installation instructions in this manual, you are now ready to use your Cirrus Logic VGA equipped computer system. Most software that is compatible with IBM's Personal System/2, VGA or EGA will run automatically on your system using the VGA Card. Just turn on your computer system and install your application package for PS/2 model 50, 60 or 80 video, VGA, or EGA as instructed by the software manufacturer.

Utility software
Several utility programs are supplied with your 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. 
Switcher is a TSR (Terminate and Stay Resident) program that provides much of the functionality of CLMode in a hot-key environment.
The bold font utility allows higher contrast levels in some video modes on the LCD display.
WinPanel is a Windows program that provides much of the configuration power of CLMode from within Windows 3.1.
CRT, Panel and Simul are programs to set the current display type from the DOS command line or from within Windows 3.1.

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.
To use 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. 
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
Select Monitor button. The Monitor Type Setup window will be displayed. The current monitor type will be highlighted initially. Use the keyboard or the mouse to choose the type of monitor attached. Press the OK 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.
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 to return to the Video Modes Preview window.
Retrieving the current VGA controller status
The information in the CLMode main window displays the VGA controller type, the BIOS version number and the amount of video memory present.
Configuration
The configuration section allows the user to set flat panel options. Some options are designed for a specific display mode, that is CRT, SimulSCANTM, or flat panel.  The following options take effect in flat panel display mode: Reverse Video, Bold Font, Expand, Font Load, Panel Power, Black & White Enhancement, Display, Graphics Shading, Text Shading, Vertical Position, and Power Management.
The following options are available in SimulSCANTM display mode: Reverse Video, Font Load, Display, Graphics Shading, and Text Shading.
The following options are available in CRT display mode:  Font Load, 640X480 CRT Refresh and Display.
Some flat panel options have no effect on color panels.  Refer to the specific option descriptions for more information.
Reverse Video
This option sets whether or not the flat panel will be displayed in reverse video.  Reverse Video applies to monochrome panels.  Text and graphics modes may be selected independently.
Panel Bold Mode
This option displays text characters (with the foreground intensity bit set) with a "bold" font and only applies to the flat panel.  The "bold" font must be loaded using a DOS utility program before enabling this function.
Panel Expanded Mode
This option controls the vertical expansion of text and graphics modes to fill as much of the flat panel as possible.
Font Load
This option loads a supplemental font to enhance display quality when switching from CRT to panel or CRT to SimulSCANTM and is only used for text mode.  
The supplemental font may interfere with some text programs which load their own font.
Panel Power
This option selects between standard and low-power panel usage and takes effect only in flat panel display mode.  The standard setting provides a sharper image, while the low-power setting will save power.  Color panels disregard this option and remain in the standard setting.
B/W Enhancement
This option produces greater contrast in text modes by forcing color attributes to be displayed as either black, white, or a single shade of grey.  When disabled, grey shading is assigned based on the options selected by Text Shading.
640x480 CRT Refresh
This option controls the refresh rate for 640x480 resolution modes on the CRT. When it is selected, all 640x480 video modes will have a vertical refresh rate of 72Hz. Since some monitors cannot use this higher refresh rate either check the monitor's documentation, or set the option and then use the preview option to verify that it works correctly. Since this is a standard VGA resolution and is available on all VGA-compatible monitors, it is not covered by the Monitor Type selection. 
Display
This option controls whether the panel, CRT, or both are the current output device, and takes effect immediately.  In SimulSCANTM both the panel and the CRT are active; an option generally used for presentation mode.  If the current mode on the CRT is greater than 640x480 resolution, no display switch will occur.
Graphics Shading
This option controls the method of converting color data to a monochrome panel in graphics modes and has no effect on color panels.  There are two selections: NTSC shading and Green Only (only the green color is used as the grey shading source).  Select the option which produces the best display for your application.
Text Shading
This option controls the method of converting color data to a monochrome panel in text modes and has no effect on color panels.  There are three selections: NTSC shading, Green Only (only the green color is used as the grey shading source), and Direct Mapping.  Select the option which produces the best display for your application.
Vertical Position
This option controls the vertical placement of video modes that do not use the full flat panel display.  It has no effect while expand mode is turned on.
Power Management
This option provides power saving features and is only available in flat panel display mode.  Select the power management option and set the timer to enable this option.
Standby is a power saving mode which allows application programs to continue to update the display memory while the flat panel power is disabled.
Backlight power savings can be achieved by disabling the backlight while continuing to update the flat panel display.  In bright daylight the backlight may not be required to use the display.
Mem indicates that the power management mode will be entered when application programs do not access video memory for the time specified by the timer.
Keybd indicates that the power management mode will be entered when the keyboard is not used for the time specified by the timer.
Getting help
CLMode provides Help for the following items: Panel Configuration, Monitor Type, Video Modes, Mouse, Keyboard and About CLMode. The Panel Configuration help window explains the different capabilities of the controller, affecting the flat panel display. 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 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 and the monitor type will be displayed.
Using CLMode's command line options
When command line options for CLMODE.EXE are given at the DOS prompt the specified options will be set and then you will be returned to the DOS command line. For a list of the command line options and their syntax type CLMODE ?[Enter]. Typing an invalid option will also display the options list.

Table 2: Monitor type examples
Switcher
The Switcher utility allows rapid configuration of the VGA subsystem. It is a TSR (Terminate and Stay Resident) program. That is, once loaded, it remains in memory and can be invoked by keystrokes from the keyboard.  To run Switcher type:
SWITCHER [Enter]
after returning to the DOS prompt.  The system then responds to individual Switcher commands.
Using the SWITCHER functions  
The following table describes the various functions performed by Switcher and the corresponding keyboard commands necessary to invoke these functions.
Feature 	Keystroke 
Black & White Enhancement ON/OFF 	Ctrl-Shift-A 
Bold ON/OFF 	Ctrl-Shift-B 
Switch between vertical positioning options (Top and Center) 	Ctrl-Shift-C 
Switch  between flat panel, CRT, and SimulSCANTM 	Ctrl-Shift-D 
Expand mode ON/OFF 	Ctrl-Shift-E 
Graphics shading 	Ctrl-Shift-G 
Text shading 	Ctrl-Shift-T 
Inhibit font load ON/OFF 	Ctrl-Shift-L 
Panel power usage (Low/Normal) 	Ctrl-Shift-P 
Reverse video ON/OFF 	Ctrl-Shift-R 
Screen power ON/OFF 	Ctrl-Shift-S 

Table 3: Switcher Keystrokes
All Switcher commands operate in toggle mode.  That is, each occurrence of a command causes the corresponding function to switch either to the opposite of its current state, if there are two states; or to the next state in line, if there are more than two states.  Some of these options are only available in certain configurations.
Bold font driver
The bold font utility allows a higher contrast level in some video modes on the flat panel.  Most panels do not provide as high of contrast as a CRT. The bold font utility increases the contrast by providing a bold font that is used in place of text that is bright or bold on the CRT.
This feature is especially useful with some display options (such as black and white enhancement or graphics shading). In these cases all text will look similar unless the bold font driver is loaded.  
BOLD_DRV.COM is compatible with most programs, but a few applications that reprogram the standard or alternate character set may not work properly with this utility.
To run the bold font driver, type BOLD_DRV[Enter].  If you want to run it automatically when you turn on your computer then it should be added to the AUTOEXEC.BAT file.

SetRES
The  SetRES utility runs under Windows 3.1 and allows the user to change the screen resolution, number of available colors, and to select either large or normal size 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. 
This application assumes that the Windows drivers have been correctly installed and configured using Windows Setup.
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.
Install and configure the actual Windows driver following the instructions in the Windows 3.1 section of this manual.
SetRES may now be run by selecting the SetRES icon. The first time that you run SETRES, the settings for the current driver won't be correct, but go ahead and set them once, and they will be correct from then on.
If you are unsure what resolutions and colors your video card can support, refer to the section of this manual on CLMode for information on how to determine supported resolutions.
For help on the SetRES utility, select Help from the program menu.
WinPanel
The WinPanel utility gives the user the ability to configure the display from within Windows 3.1. 
It's operation and appearance are similar to the configuration screen in CLMode. It will be installed into Windows at the same time as the SetRES if the installation instructions for SetRES have been followed. WinPanel is executed like any other windows program, by double clicking on the icon or single clicking on it and selecting Run from the File menu of the Program Manager.
Operation
The configuration section allows the user to set flat panel options. Some options are designed for a specific display mode, that is CRT, SimulSCANTM, or flat panel.  The following options take effect in flat panel display mode: Reverse Video, Bold Font, Expand, Font Load, Panel Power, Black & White Enhancement, 640x480 CRT Refresh, Display, Graphics Shading, Text Shading, Vertical Position, and Power Management.

Keybd indicates that the power management mode will be entered when the keyboard is not used for the time specified by the timer.
CRT, Panel, and Simul
These utilities are provided to make switching between displays easier. They are installed as part of the same process that installs SetRES and WinPanel. These utilities will run from the DOS command line or as Windows 3.1 programs. 
To execute them from the command line, type
CRT[Enter]
or 
PANEL[Enter]
or 
SIMUL[Enter]
To execute them from Windows 3.1, double click on the appropriate icon or single click on it and select Run from the File menu of the Program Manager.  
The CRT utility changes the display so that it is running on the monitor.
Panel sets the display to run on the flat panel if the VGA is in a video mode that will run on the panel (usually 640x480 or lower resolution).
Simul sets the display to run on the panel and the CRT at the same time if the VGA is in a video mode that will run on the panel (usually 640x480 or lower resolution).
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.
The VGA controller 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 be 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.
Microsoft Windows
Installing Windows 3.1 display drivers
To install the Windows 3.1 drivers from the DOS prompt, proceed as follows:
Insure that Windows 3.1 is already installed on your computer.
From your Windows directory, at the DOS prompt, type SETUP[Enter] to run the Windows SETUP.EXE program. Follow the instructions on the screen. When you come to the screen which lists the hardware and software components such as display adapter (e.g. VGA, CGA, etc.), keyboard type, mouse type, etc., go to the Display selection by using cursor keys to move the highlighted bar and press [Enter].
From the next menu listing of display options, scroll to the bottom of the list, and highlight the following text:

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 AutoCADs operation besides speeding the program up; it runs with AutoShade 2 with RenderMan and 3D Studio to provide enhanced rendering support, but does not affect the speed of these programs, since they do not support Display Lists. 
Installing TurboDLDClassic does not change any of the AutoCAD program files or alter any of the drawing files stored on disk. TurboDLDClassic was designed to be an easy-to-use, feature-filled product that makes using AutoCAD faster and more productive, not one that makes AutoCAD more complicated and difficult to use. 
How does TurboDLDClassic make AutoCAD run faster? There are three things the driver does to speed operation:
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).
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. 
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.
Whats the catch? 	
The only resource used by TurboDLDClassic is memory. The driver actively uses about 300Kbytes of RAM from extended memory for its operation. This memory is drawn from AutoCAD's memory pool and therefore does not affect normal DOS operation. The driver is loaded by AutoCAD at AutoCAD load time and is unloaded when AutoCAD is exited.
Additionally, the Display List size can vary from one tenth to three times the size of the current drawing file, particularly when using AutoCAD 12's 31-bit regen space.
You may wish to purchase and install additional RAM before installing TurboDLDClassic, since it shares memory with AutoCAD. If AutoCAD is using a lot of memory, TurboDLDClassic may not have enough. If there is significant hard disk activity while you are using TurboDLDClassic, it may be an indication that you should add more memory to your system.
Installation
Insert the Cirrus Logic drivers diskette into Drive A: (or B:). Run the Cirrus Logic installation program (INSTALL.EXE), and choose the option for the Autodesk/AutoCAD drivers and specify the drive and directory where you want them copied to (such as C:\ACAD\DRV). 
Since the start-up is a little bit different for AutoCAD Release 12 than it is for older versions, please follow the instructions for the version of AutoCAD you will be using TurboDLDClassic with.
To configure AutoCAD 12
Begin AutoCAD with the reconfigure switch by typing
ACAD -R[Enter]
Choose option 3, Configure Video Display from the AutoCAD configuration menu.
Type Y at the Do you want to select... message to display the available video options for AutoCAD.
Select TurboDLD Classic by Panacea Inc. from the list of display options.
If you chose to install TurboDLDClassic into a sub-directory other than ACAD\DRV, be sure to modify the ACADDRV environment variable to include that sub-directory. Otherwise, the TurboDLDClassic selection will not appear in the list of available drivers. 
To configure AutoCAD 11/386
Run the FASTACAD.BAT that was copied to the TurboDLDClassic sub-directory by typing:
C:\TURBODLD\FASTACAD[Enter]
The above example shows that TurboDLDClassic was installed on drive C: in the TURBODLD sub-directory.
Start AutoCAD and reconfigure it to use TurboDLDClassic by selecting option 5, Configure AutoCAD from the AutoCAD main menu. From the next menu, select option 3, Configure Video Display. Choose Item 1, P386 ADI 4.0/4.1 (R11) as your display device. (For more information, see your AutoCAD 'Installation and Performance Guide.')
TurboDLDClassic configuration
After selecting the proper display device, the TurboDLDClassic driver configuration menu will appear.
Set-up of TurboDLDClassic requires configuration of its various operating parameters. These parameters have been logically grouped into menus based on their interaction with AutoCAD. A quick trip through each menu will complete the configuration process. Context sensitive help can be obtained by typing [?] at any menu option. 
That the DLDSETUP.HLP file must be present in order for help to appear. If you get an error message, be sure that the file DLDSETUP.HLP is in the ACAD\DRV sub-directory (R12), or in the TURBODLD sub-directory (R11).
If at any point during the configuration process you want to change an item on a previous screen, just press the [ESC] key to back up. Selecting NO SAVE, EXIT at the main configuration menu will return you to the AutoCAD configuration menu without making any changes.
At a minimum, a graphics board and screen resolution must be chosen from the Select Graphics Board/Resolution menu. If no display options are configured, the driver will be automatically configured for Generic VGA, 640 x 480 resolution at 16 colors.
The first menu, Select Graphics Board/Resolution, configures TurboDLDClassic for the graphics board, and display and rendering resolutions to be used. Prior to configuring TurboDLDClassic, run the CLMode utility and check the first screen to determine which Cirrus Logic chip and how much memory is on your VGA adapter. 
Select Graphics Board - Selects the graphics chip being used
Select Display Resolution - Selects AutoCAD, 3D Studio and AutoShade main display screen resolutions
Select Rendering Resolution - Selects AutoCAD 12, 3D Studio and AutoShade rendering resolutions
When configuring TurboDLDClassic's display options, the Rendering Board/Resolution options described below will automatically appear ONLY when configuring AVE Render, 3D Studio or AutoShade. Otherwise, the Display Board/Resolution options will be the only menu choices available.
Basic Configuration options set AutoCAD screen characteristics, number of text lines in the command-line area, font size and dual screen mode.
AutoCAD Text Lines - Selects number of lines in AutoCAD command prompt area. The default is 3 lines, but values from 1 to 10 can be specified. A number larger than 3 might be useful if you are using this driver in a high resolution mode with small fonts, eliminating the need to frequently swap back and forth between the text and graphics screens.
If you do not want any lines of text at the bottom of the display, use AutoCAD to disable the command area (see the AutoCAD 'Interface, Installation and Performance Guide' for more information). Press [Return] to continue with font selection.
Font Size - Selects AutoCAD display screen font or font file to be used. Choose the Font Size you would like to use for your AutoCAD menus, pull-downs, and dialog boxes: 8x8/8x14/8x16/12x20/12x24. For resolutions over 800x600 we recommend the 12x20 or 12x24 fonts. The default is the 8x14 font.
Dual Screen Mode - Enables or disables dual screen operation of AutoCAD.
User Interface options include the parameters for maneuvering within AutoCAD. Using these options, the Big Picture, Panacea's bird's-eye view, can be configured to suit your needs or allow for better differentiation within a complex drawing. 
Double Click - The Double Click option allows you to set the delay for TurboDLDClassic's Big Picture pop-up. This time represents the largest amount of time that can elapse between the release of the digitizer button and the subsequent press of the same button in order to detect a double click and display the Big Picture. Setting this number too low will result in the computer seeing two separate clicks, while setting the time too high may slow down response time for single button presses. Values between 10 and 30 are recommended.
The Double Click time is measured in hundredths of seconds. PC systems have a timing resolution of 5/100ths of a second, therefore, the entered time is rounded by the driver to most closely approximate the nearest multiple of 5. This means that a time setting of 23 is the same as a setting of 27, both of which get rounded to 25 (or one-quarter of a second). In simplest terms, when adjusting the timing value, it is best to use multiples of 5.
BP Button - Sets mouse/digitizer button to use for Big Picture. With the BP Button option, TurboDLDClassic gives you the flexibility to use a double click on an available digitizer/mouse button as a Big Picture pop-up button. On the BP Button menu line, enter the number of any available digitizer button other than button 1 - button 1 is reserved as the pick button. Within AutoCAD, simply double click the chosen button to invoke the Big Picture.
BP Highlight Mode - Controls how the Big Picture will appear on the screen. Patt Line will display the Big Picture using dotted lines to form the outer bounding box and the zoom crosshairs. XOR Rect will use a contrasting rectangle to display the Big Picture. The Both option will use a combination of Patt Line and XOR Rect to distinguish the Big Picture.
BP Refresh - In it's fastest mode, TurboDLDClassic does not refresh the Big Picture until a DLDREFRESH command is issued. Depending on a drawing's complexity, in this mode, the Big Picture could become confusing, displaying vectors that are now actually erased, and no longer part of the drawing. To configure the Big Picture to be updated as objects are drawn or erased, enable the BP Refresh. If speed is a major concern, disable it.
BP Cache - Enables or disables TurboDLDClassic's internal memory cache for Big Picture functions. This cache will speed up Big Picture operations on some graphics platforms, primarily on TIGA-based graphics boards. For this reason, the BP Cache is normally disabled. As a reference, on VGAs, the performance benefit of the BP Cache is as little as 1%. With a TIGA-based graphics board, however, the performance benefit of the BP Cache is as high as 400%.
The Expert Configuration menu sets the function of TurboDLDClassic itself. This menu allows for customization of the driver for speed or to adjust for memory constraints.
Display List - Enables or disables the display list feature of TurboDLDClassic. This option should always be set to enable, disabling the Display List will cause TurboDLDClassic to run as an ordinary non-display list driver.
Drawing Cache - Enables or disables TurboDLDClassic's internal drawing cache, a compressed list of the current viewport, which speeds up pans zooms and redraws. As in the Display List option, Drawing Cache should normally be enabled. In low memory situations, it may be desirable to disable the Drawing Cache. Disabling the drawing cache will free-up memory for AutoCAD but may or may not have a visible effect on your ZOOM and PAN performance. For example, on VGAs, the performance benefit of the drawing cache is as little as 5%. With a TIGA-based graphics board, however, the performance benefit of the drawing cache is as high as 400%.
AutoCAD Logical Drawing Space - Using AutoCAD 31-Bit Space, configures TurboDLDClassic for use with AutoCAD R12's 31-Bit logical drawing space. When set to Yes, the driver will use AutoCAD's extended 31-Bit drawing space. Selecting No, will use a 15-Bit drawing space, similar to that of AutoCAD R11.
The 31-Bit logical space allows you to extend your Regen-less zooming ability by a factor of several million, at the cost of more memory. Additional memory is used by AutoCAD for the drawing space, and by TurboDLDClassic for the Display List. 31-Bit zooming and panning is about 10%-20% slower than for 15-Bit logical space. The Use AutoCAD 31-Bit Space setting is ignored for AutoCAD R11 installations.
Internal Command Echo - The echo of TurboDLDClassic internal commands can be enabled or disabled with the Internal Command Echo option. If you would like to see TurboDLDClassic's internal commands display at the AutoCAD command line as they are executed, enable this option.
Big Picture Zoom Mode - Sets the Big Picture (BP) zoom definition area display options. In a zoomed view of the static BP, as the current viewport is zoomed or panned, Float mode causes the image in the BP to move around within the bird's-eye window, keeping the zoomed viewport area fixed in the center of the bird's-eye. Freeze mode will lock the current BP contents into place to provide a better overall frame of reference.
Regen Mode - As a convenience feature, a Regen Mode option has been added to TurboDLDClassic. A Fast Regen will store the AutoCAD drawing until the Display List has been created, and then display it, all at once. The Incremental mode displays the drawing in 'chunks' as the display list is created. The Fast mode causes Regens to process approximately 5%-10% faster than the incremental. Neither mode changes memory requirements.
After all options have been set, use the arrow keys to scroll down to the Save and Exit option and then press the [Enter] key to continue.
Next, configure the AutoCAD screen display characteristics and then type [Y] to accept the changes.
Exit to the AutoCAD drawing editor to begin using TurboDLDClassic.
The last step in setting-up TurboDLDClassic is to configure the colors for AutoCAD. From the AutoCAD Command Line, type DLDCOLOR[Enter], to start CustomColors, TurboDLDClassic's color configuration utility. Make any desired color changes and then Save the new color palette and then Exit to return to the drawing editor.
Verifying your TurboDLDClassic installation
To verify that TurboDLDClassic is running and installed correctly, follow one of these two simple tests.
If you have the AutoCAD side menu enabled, look for the Panacea Logo in the lower right-hand corner.
If you are running AutoCAD without a side menu, type DLDVER[Enter] at the AutoCAD command prompt. If TurboDLDClassic is loaded and running, this command should return your current version, and serial number.
Reconfiguring TurboDLDClassic
To reconfigure TurboDLDClassic follow the instructions below for your version of AutoCAD, Release 12 or Release 11.
AutoCAD Release 12
If you need to make changes to your Release 12 TurboDLDClassic configuration, type CONFIG[Enter] at the AutoCAD command prompt or use ACAD -R[Enter] when starting the program. Select option 3, Configure Video Display. Answer No[Enter] to the Select a new videodriver ... prompt to start the TurboDLDClassic configuration program. Make the desired changes to the driver and then Save and Exit to continue to the AutoCAD drawing editor.
AutoCAD release 11
To change a Release 11 configuration, select option 5, Configure AutoCAD from the AutoCAD main menu, and then from the configuration menu, select option 3, Configure Video Display. Answer no to the Select a new video driver ... prompt to start the TurboDLDClassic configuration program. Change the desired driver options. Save and Exit to return to the AutoCAD configuration menu. Open or begin a new drawing. 
To completely reconfigure TurboDLDClassic using Panacea's defaults, delete DLDSETUP.DAT from either the \ACAD\DRV sub-directory (R12) or the TURBODLD sub-directory (R11) and then follow the Driver Configuration instructions earlier in this chapter.
Configuring an AutoCAD 11 environment
During the TurboDLDClassic installation process, a FASTACAD.BAT file is created and placed into the TURBODLD sub-directory. FASTACAD.BAT contains four lines that set four separate environment variables: DLDCFG - used by TurboDLDClassic to find all of its configuration files; and DSPADI, RCPADI, RDPADI - used by AutoCAD, 3D Studio and AutoShade 2 w/RenderMan, respectively, to find the driver file. FASTACAD.BAT must be run prior to starting AutoCAD R11 and only needs to be run once per system boot. For automatic loading of the environment variables, FASTACAD.BAT may be added to the AUTOEXEC.BAT file or an AutoCAD start-up batch file. 
To add FASTACAD.BAT to your AUTOEXEC.BAT file, insert the line	
CALL D:\TURBODLD\FASTACAD
anywhere in the file. The above example assumes that FASTACAD.BAT resides in a sub-directory on drive D: called \TURBODLD.
If you dont wish to put FASTACAD in your AUTOEXEC.BAT file, you may put it in a batch file which also starts AutoCAD, or simply remember to run the file before starting AutoCAD.
If you get the message Out of Environment Space when you run FASTACAD.BAT, you will need to enlarge your system's environment. This is accomplished by adding the following line,
SHELL=C:\COMMAND.COM /P /E:768 
to your CONFIG.SYS file. The /E:768 specifies an environment size of 768 bytes. Change this number as appropriate. You will need to reboot after modifying your CONFIG.SYS file, in order for the changes to take effect. 
Configuring AutoShade, 3D Studio and AVE Render
AutoShade
To configure AutoShade v2.0 to use TurboDLDClassic, first run the FASTACAD.BAT file from your TurboDLDClassic sub-directory to set the AutoShade environment variables. Next, start AutoShade with SHADE /R[Enter], which will allow you to reconfigure AutoShade. For the display device, select P386 Autodesk Device Interface display driver, and for the rendering display select the P386 Autodesk Device Interface rendering driver. If you are running the display and rendering screen on the same monitor (i.e. single monitor), make sure to tell AutoShade this. A single monitor approach will require a redraw of the display screen after a rendering screen.
Next, follow the same installation steps that were used to select the graphics board and display and rendering resolutions for AutoCAD.
3D Studio
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. 
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.
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. 
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. 
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. 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.

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

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 123 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 v3.1, v3.2, v3.3
To install a Lotus 3.1 display driver, proceed as follows:
It is assumed that a compatible version of Lotus 123 is already installed on your hard disk, using the standard Lotus installation utility. To install this driver, make the directory containing 123 the current directory. For example, if 123 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 123 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 123 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 fille (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. 
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 123 distribution, with two additional choices. GD62X5 100 Column Display (800x600 resolution) supports 100x31, 100x42, and 100x75 16 color modes. GD62X5 128 Column Display (1024x768 resolution) supports 128x40, 128x54, and 128x96 16 color modes. Select a resolution that best meets your requirements.
After you selection is made, choose the Save Changes option from the menu. 
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.
