Set-Up Utility (DLDSETUP.EXE)
=============================
To help answer set-up questions we have added context
sensitive help to the DLDSETUP program. At any prompt, just
hit the question mark ("?") to get help specific to the prompt
you're at. The help text is stored in a file called
DLDSETUP.HLP.
**** NOTE: Please use the help facility before calling us for
technical support. It has been designed to answer the most
commonly asked configuration questions.
Enviroment Variables (DLDCFG) and DLD-VGA Files
===============================================
Running DLDSETUP will create two files: DLDSETUP.DAT - the
DLD-VGA configuration file; and a file called FASTACAD.BAT - a
batch file containing all the commands needed to run DLD-VGA.
Among the commands in the batch file is a line that sets an
environment variable called DLDCFG. DLDCFG is set to point to
the directory containing the DLD-VGA software, and is used by
DLDSETUP, COLOR16, COLOR256, DLDVGA, and DLDVG256, to locate
the files DLDSETUP.HLP, DLDCOLOR.HLP, DLDSETUP.DAT, and
DLDCOLOR.DAT. If DLDCFG is not set, those files are assumed to
be in the current directory. The FASTACAD.BAT is always
assumed to be in the current directory, regardless of whether
or not DLDCFG is set.
CustomColors(tm) Color Configuration (COLOR16 & COLOR256)
=========================================================
We're pleased to present our revolutionary color configuration
utility - CustomColors(tm). Using CustomColors, you can
configure all your AutoCAD object colors, such as menus, pull-
downs, and dialog boxes, as well as your drawing colors and
physical colors, all in a simulated AutoCAD screen, with
context sensitive help at every prompt. Using CustomColors, if
you were so inclined, you could configure your colors such
that all text were fuchsia and all backgrounds were mauve.
There is no restriction on your color settings any more!
COLOR16 is CustomColors for the 16 color VGA modes, and
COLOR256 is for 256 color VGA support.
256 Color Support
=================
The DLD-VGA software now supports both 16 and 256 colors under
AutoCAD. Just select how many colors you want when you set-up
DLDVGA. Make sure to also use the correct version of
CustomColors after you have finished configuring the software.
If you want to run in the 256 color modes, make sure your VGA
supports a resolution of at least 640x400 with 256 colors - a
resolution not available with a plain-vanilla VGA, such as
that in the IBM PS/2s.
Current Drawing Color Indicator
===============================
To resolve the problems that occurred when a drawing color of
blue was selected (the entire status line would virtually
disappear), we have changed the indication of the current
color to a small box on the left edge of the status line. This
white-outlined box will always reflect the active
drawing/layer color.
Font Selection
==============
You can select from three different fonts for your AutoCAD
menus and prompts: a small 8x8 font, the standard 8x14 font,
or even a slightly larger 8x16 font. This selection occurs in
DLDSETUP, in the Driver Configuration Menu.
DLDCLEAN
========
Since our Remove mode for erasing objects is quite slow when
moving or erasing sizeable portions of a drawing on large
images, and Overwrite increases display list sizes quite
rapidly, but with no display list clean-up, we have added a
function to remove all erased objects from the display list.
To perform this operation, just type DLDCLEAN at the AutoCAD
command prompt, and the whole screen will be redrawn while the
DLD-VGA software cleans up its display lists. This operation
is substantially faster than a REGEN, and is especially useful
if you are erasing or moving large portions of your drawing.
As such, we now recommend that you run in the Overwrite mode
for display list processing. Note that if you are running with
multiple viewports, all viewports and their display lists will
be cleaned up.
REGEN Avoidance
===============
Since DLD-VGA is a true ADI 4.0 driver, and therefore is
completely AutoCAD transparent, it has no control over REGENs.
This means that doing a ZOOM All or ZOOM Extents will still
cause a REGEN, because AutoCAD does not keep track of various
boundaries necessary to avoid the REGENs. But, REGENs can be
virtually eliminated by using two regular AutoCAD features. The
first turns off automatic REGENs when you ZOOM in too far or PAN
too far over, and is called REGENAUTO. Just type REGENAUTO OFF at
the ACAD prompt to prevent automatic REGENs. To avoid the REGEN
incurred by ZOOM ALL and ZOOM EXTENTS, use AutoCAD's VIEW feature
to save the view when zoomed all the way out (i.e. VIEW SAVE
ALL), and then just restore it (VIEW RESTORE ALL) when you want
to see the big picture again.
Memory Requirements
===================
A clarification of the memory requirements for DLD-VGA is
necessary. The driver, when configured to use at least 64K of
EMS/expanded memory, uses approximately 45K of DOS memory. If
DLD-VGA is configured to use _only_ extended memory (and/or
disk), another 32K will be allocated by the driver to use,
resulting in a total of 77K in use. This effect can be negated by
using a utility like QEMM-386 or hardware like the ALL
Chargecard. Both of these items allow you to 1) Convert extended
memory to expanded, and 2) Load the driver into memory above the
640K mark.
Also, once your system is fully configured and running with DLD-
VGA, you may want to adjust your display list memory allocations
by using the DLDUSAGE command at the AutoCAD command prompt while
you are in a drawing. The DLDUSAGE command will provide you with
information about how much memory is actually in use by both the
display list and the fast redraw list.
Environment Variables
=====================
When the installation program creates the FASTACAD.BAT files, it
also includes settings for the AutoCAD Release 10 memory
variables. If you happen to be running AutoCAD 386, these
variables can be ignored, as AutoCAD 386 does not use them and
DLD-VGA should be pre-allocating the memory it requires. The
variables are, however, required in order to run DLD-VGA with
Release 10.
SPECIAL FEATURES!!!
===================
This special SpeedSTAR version of DLD-VGA offers two features not
found in Panacea's retail DLD-VGA, namely an on-screen memory meter
and automatic edge panning.
The on-screen memory meter reflects how much memory DLD-VGA has
had to allocate for its display list. Note that the amount listed
here may be slightly higher than the amount listed when you use
the DLDUSAGE command, because of how memory allocation functions.
Automatic Edge Panning is invoked by typing DLDPANON at the AutoCAD
command prompt. If you have the side menu enabled, "EDGEPAN" will be
displayed in the lower right corner while edge panning is enabled.
To use the automatic edge panning (while it's enabled), just leave
your cursor close to an edge of your current viewport for half a
second, and DLD-VGA will automatically start panning in that direction.
Panning should stop just prior to causing a REGEN. Note that the
cursor should not be exactly at the edge in order to invoke automati
