information that has changed or is different from the Installation
Guide, as well as some other useful tips.


I. TIPS/ERRATA/FEATURES/REVISIONS
============================================================

Support for AutoCAD R12/Windows
-------------------------------

This version of TurboDLD is designed to specifically support DOS
versions of AutoCAD 10/386, 11/386 and 12. Panacea is currently
developing a driver which will support AutoCAD for Windows.
Registered users of TurboDLD will be notified when this driver is
available.



AutoCAD Release 10/386 & Release 11 Limitations
-----------------------------------------------
TurboDLD has the following limitations when installed for use with
AutoCAD Release 10/386 & Release 11:
     
      1. Cannot use the "Text Window on Single" Pop-up Text Window.
      
      2. Due to the manner in which AutoCAD Release 10/386 works,
	 the TurboDLD function DLDBPMODE, as well as the MACH-12 
	 compatible ZI, ZO commands are not currently supported in 
	 this TurboDLD release when using AutoCAD Release 10/386.


Font Selection          
---------------
   TurboDLD includes an array of fonts for AutoCAD menus and dialogs.
   In addition to the Panacea supplied fonts, TurboDLD also supports 
   .BDF fonts. Primarily for foreign AutoCAD support. .BDF fonts are 
   usually public domain and are easily available through Shareware.
   AutoCAD Release 12 includes various .BDF fonts

   Please note that .BDF fonts are not supported for XGA and 8514/A
   graphics boards. Only Panacea supplied fonts are available those 
   boards.


   Enabling .BDF Fonts
   -------------------
   In order to enable .BDF font support in TurboDLD, you must either
   start AutoCAD from your main AutoCAD sub-directory, or set the DLDFONT 
   environment variable prior to starting AutoCAD. Syntax of DLDFONT is:

		SET DLDFONT = {FONTDIR}

   where {FONTDIR} is the full path name to the sub-directory which 
   contains the .BDF fonts.

   If DLDFONT is not set, TurboDLD will look for a \DRV directory
   off of the default AutoCAD directory. If no .BDF fonts are found
   in the DRV directory, then only Panacea supplied font options 
   will be available.


   Choosing .BDF Fonts 
   -------------------
   To use a .BDF font in TurboDLD, choose the Basic Configuration menu
   "Select Font From List" option to display a list of available fonts.
   The list will contain available fonts, limited by the settings of the
   DLDFONT environment variable and the font filter chosen in the Basic 
   Configuration menu Select Font Filter option.
   
   
   Limiting Font Selections
   ------------------------
   If you have many .BDF fonts on your system and you wish to select only 
   a certain style of font, TurboDLD offers a filtering mechanism to allow 
   you to select only a certain types of fonts based on their internal
   CHARSET_REGISTRY name or Code Page definition. 
   
   To select a specific .BDF font type, from the Basic Configuration menu, 
   use the Select Font Filer option and then select an available .BDF font 
   type. If you wish to see all installed fonts, choosse All Fonts. Your 
   font filter will be in effect when you select the Select Font Filter 
   menu option.

   Font Size and AutoCAD
   ---------------------
   When using a font size in which the height is more than twice the width
   (i.e., 7x15) you may experience text and other display problems within 
   some dialogs. This is due to the way AutoCAD calculates display positions 
   using font character values.


Graphics Mode Text Window          
--------------------------

Please note that the Text window on graphics screen works with AutoCAD 
Release 12 only.


   Text Window Caveats
   -------------------
	
	RCONFIG
	-------
	If TurboDLD is configured for "Text Window on Single" and
	RCONFIG is used to configure AVE Render, you may have problems
	selecting menu items. If this happens, type CTRL-C to exit
	RCONFIG and return to the AutoCAD drawing editor. Then 
	reconfigure TurboDLD for "Single" screen operation and 
	then run RCONFIG again.

	Random Characters in Menu Areas
	--------------------------------
	On some graphics boards, when TurboDLD is configured for "Text 
	Window on Single" random characters characters may appear in the 
	AutoCAD menu areas. If this occurs, configure TurboDLD for "Single"
	screen mode. Do not continue to use the text window, unpredictable 
	results may occur.

	Networked AutoCAD Installations
	-------------------------------
	On a networked AutoCAD Release 12 system, if the maximum number
	of users is reached, an alert dialog box is displayed. When
	using TurboDLD in the "Single" screen mode an abnormal AutoCAD
	termination may occur instead of the alert dialog box. If you 
	think this may be a problem, configure TurboDLD for the "Text 
	Window on Single" option.


	WCEdit
	------
	Elsa's WCEdit utility may appear to hang when TurboDLD is 
	configured for the "Text Window on Single" mode. In fact, WCEdit
	has not hung - instead it is waiting for user input. When the
	TurboDLD text window is enabled, WCEdit still thinks TurboDLD
	is in a text-mode screen and tries to write directly to it. This
	will not work. Press Ctrl-X to return to AutoCAD from WCEdit.
	If you wish to use WCEdit with TurboDLD, configure for "Single"
	screen mode.


AutoCAD Command Line Cursor          
---------------------------
	  
A "-" cursor has been added to the AutoCAD Command line to identify the
current AutoCAD cursor location.


New TurboDLD Command
--------------------

In some instances, lines may overwrite AutoCAD menu areas. To restore
the menu areas, you may either do a flip-screen to the text screen or
issue the new TurboDLD command DLDRESTORE.


Graphics Platform Specific Problems
-----------------------------------

    XGA
    ---
    If you are using an original XGA, it is perfectly normal to see the
    following message come up under AutoCAD and 3D Studio:

		    DMQS Not Found!

    If you have an XGA-2 and this message comes up, it means that you
    have either not properly installed the board, or not properly installed
    the DMQS software that should have come with your board.

    
    XGA & IIT AGX
    -------------
    This version of TurboDLD does not support boards using either IBM XGA
    chips or IIT's AGX chips in 16 color modes. Use the 256 color modes
    instead.
    

    S3-based Graphics Boards
    ------------------------
    The 24-bit modes (16 million colors) for some S3 boards are not
    supported in this TurboDLD release.

    801/805-based S3 boards with only one megabyte of video memory will
    not display colors properly at 32k or 64k colors (15 or 16 BPP modes).


    TIGA-based Graphics Boards
    --------------------------
    If you are using AutoCAD 10/386, it will be necessary to run the 
    AutoCAD 11 NEWDX.EXE utility to update the Phar Lap DOS extender to 
    run properly with TurboDLD.

     
       NEC Multisync Graphics Engine
       -----------------------------
       NEC Multisync Graphics Engine based TIGA boards may leave errant 
       crosshairs on the screen under dialog boxes, menus and with the 
       spy glass. Also, selecting fonts other than the default for the MGE 
       may cause unpredictable results.

       When configuring for an NEC Multi Graphics Engine, add the following
       line to the DLDSETUP.DAT file created by the TurboDLD setup program.

	      TIGA REINIT

       The above line may be placed anywhere in the file provided it is not 
       preceded by a ;. This will reinitialize the graphics screen when 
       returning from a flip screen.


    Weitek P9000
    ------------
    With P9000-based graphics boards, erasing small objects or moving many
    objects may result in stray pixels being left on the screen. Issue a 
    REDRAW to remove them from the screen.

       Configuration Problems
       ----------------------

       When configuring for any P9000, if you cannot locate your graphics
       board or a generic Weitek P9000 option, or you are receiving a
       "Hardware Initialization Problems ..." error message, be sure that 
       you have properly initialized the P9000 prior to configuring 
       TurboDLD. The P9000 initialization creates an initialization file 
       which allows TurboDLD to identify and use the P9000 chip. If the
       .INI file is not found, you will receive the error message.

       For Diamond Viper VLB users, if you are properly running the 
       VIPER.BAT initialization and creating the VIPER.INI file but are 
       still receiving the "Hardware Initialization Problems ..." error 
       message, verify that the following line exists in the [hardware] 
       section of the VIPER.INI file:

	     Bus Type=VESA LOCAL BUS

       If the Bus Type line reads:
	    
	     Bus Type=VLB 

       change it to "VESA LOCAL BUS" and the error should go away.

    
    ATI VGA Wonder
    --------------
    When using some ATI VGA Wonder boards in a dual screen system 
    configured for single screen use, make sure that you start
    AutoCAD from the VGA screen. Otherwise, flip screens will result
    in a weird combination of monochrome and VGA screens. 


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

In 3D Studio v3, selection of a display font larger than 8x14 at 
640x480 resolution will cause 3D Studio to display a blank screen
which you cannot recover from. This is a limitation of 3D Studio.
If a blank screen occurs, delete 3DADI.CFG and then reconfigure
TurboDLD for an 8x14 or smaller font.


If using a TIGA graphics board with 3D Studio, we highly recommend
that you configure your display and rendering resolutions to be the
same. Some TIGA boards don't cope well with mode switches in the 
3DS environment.


When configuring 3D Studio for use with TurboDLD and XGA or P9000
based graphics boards, answer "N" to the "Are you using a VGA
graphics board?" configuration question or unpredictable results
will occur. 


The PANA3DS.BAT file copied to your TurboDLD sub-directory during 
installation is used for 3D Studio configuration. This file should 
be run prior to starting 3D Studio.



DLDCFG and AutoCAD Release 12
-----------------------------

The DLDCFG environment variable is used by TurboDLD to locate its
configuration files. DLDCFG must be set for AutoCAD Release 10/386,
Release 11, AutoShade, and 3D Studio.

When using Release 12, however, DLDCFG is not required. TurboDLD
will look for its configuration files in the same directory as the
RCTURBOD.EXP file. However, if DLDCFG is set, TurboDLD will use
DLDCFG to locate its configuration files. This could be useful in
a networked environment to allow individual users of a network-based
version of TurboDLD to maintain their own local TurboDLD configuration.



Upgrading from DLD386 or MACH-12
--------------------------------

If you are using Release 12, you do not need to run DLD386's
FASTACAD.BAT first. FASTACAD.BAT sets four environment variables
including DLDCFG, DSPADI, RDPADI, and RCPADI. None of these
environment variables are needed with Release 12 and TurboDLD. If
you set these variables in your AUTOEXEC.BAT or a batch file used
to start Release 12, we strongly recommend that you remove them.


General Information 
-------------------
If you have low amounts of CPU RAM and less than 20mb of available
hard disk space you should use the -SWAPCHK ON switch to configure
AutoCAD. This switch will give you the option of saving your
drawing when AutoCAD runs out of swap space.   The way you
configure this is to change into your AutoCAD program sub-directory
and at the prompt type:

		CFIG386 ACAD -SWAPCHK ON



    AutoCAD Revisions
    -----------------
    Please be aware that there is a C2 revision to AutoCAD Release 12.
    This revision corrects various digitizer and plotter problems.


    Rendering Resolution Options 
    ----------------------------
    The Rendering screen configuration menu will be available only when
    configuring the Rendering screens of AVE Render, AutoShade 2 with 
    RenderMan or 3D Studio.
    
    Also note that TurboDLD is a combined Display/Rendering driver
    therefore, you should select that option from AVE Render's
    configuration menu.


    Graphics Board Selection
    ------------------------
    If your graphics board is not listed in the Graphics Board Selection
    menu and you know which chip or platform your board is based on, you
    may choose the Generic selection for that chip type. If you are not
    sure which platform your graphics board is based on, please refer to
    your user's manual or contact the board manufacturer for more
    information.


    Dialog Commands
    ---------------
    If the AutoCAD Release 12 file and command dialog box usage is 
    disabled (i.e. setting CMDIA = 0 and FILEDIA = 0 ) and a drawing
    with an unresolved XREF is opened from the text screen, an error
    or system hang will occur. This is a bug with AutoCAD and ADI 
    drivers. To avoid this, use the Text Window on Single configuration
    option.


    Color Considerations
    --------------------
    In DLDCOLOR Object mode, when changing the background color, the 
    new background color is swapped with the old in order to eliminate
    the possibility of having a Drawing color the same as the background
    color, causing a blank screen.


Documentation Changes
---------------------

In "Chapter 4 - Changing Colors", p.4-2, the second paragraph should read: 

    "...change by moving the highlight box around with the arrow cursor 
    control keys and pressing ENTER..." You may use the up and down arrows
    as well as the left and right.
