NOTE: To be able to run the DGIS display driver with Windows 3.1 you must
also have installed new DGIS firmware for your display adapter, version
3.05 or greater!
Windows 3.1 DGIS Driver v3.00 Executable Code
=============================================
***BETA***
01/16/92
========
This disk contains the driver files necessary to install the DGIS
Windows 3.1 driver. When correctly installed, Windows 3.1 will be
able to utilize your DGIS display adapter for its display.
This disk is suitable for installation using the Microsoft Windows
Version 3.1 SETUP utility. Before installing the DGIS Windows 3.1 driver,
make sure that you have first installed the DGIS firmware that comes with
your DGIS display adapter. The following files are included on this directory:
READ.ME --> This file.
OEMSETUP.INF --> The file which the Windows SETUP program
uses to install the Windows 3.1 drivers
for DGIS 3.x. This is default configured
for 5.25" retail distribution of Windows.
DGIS.DRV --> The Windows 3.1 driver for DGIS 3.x devices.
DGIS.DRV size----------140176 bytes
DGISCFG.EXE --> The Windows 3.1 DGIS driver configuration
utility.
DGISCFG.HLP --> The Windows 3.1 DGIS driver configuration
utility help data file.
misc... --> Auxilliary files needed during Windows
installation.
To install the Windows 3.1 driver for DGIS 3.x you must do the following:
(NOTE: The following step by step instructions can be circumvented if
you use the new distribution of DGISCFG.EXE supplied on the WIZARD
CD)
1 - If you have previously installed Windows 3.1 for a DGIS device...
a) Make sure you are not running Windows.
b) Execute the SETUP program which Windows installs into your Windows
installation directory (default is C:\WINDOWS).
c) When prompted by SETUP for a display device page down to the OTHER
selection and choose OTHER.
d) Backspace over the A:\ prompt, and type in the following:
x:\wizsetup\nec (where x is the CD-ROM drive's letter).
Press ENTER.
e) You will see that you may install DGIS drivers that will display
large or small fonts when Windows is run. Choose the driver
appropriate for your display resolution and press ENTER.
f) SETUP will prompt whether or not you desire to overwrite a
DGIS Windows driver that had already been installed. You should
choose the option which will cause the overwrite.
g) You may be prompted to insert floppy disks from the Windows 3.1
retail release disks -- make sure that these disks are available.
h) When SETUP is finished you may run Windows 3.1 BUT first make sure
that you have installed and executed DGIS for your display card
before you do so.
2 - If you have already installed Windows 3.1 for another device...
a) Make sure you are not running Windows.
b) Execute the SETUP program which Windows installs into your Windows
installation directory (default is C:\WINDOWS).
c) When prompted by SETUP for a display device page down to the OTHER
selection and choose OTHER.
d) Backspace over the A:\ prompt, and type in the following:
x:\wizsetup\nec (where x is the CD-ROM drive's letter).
Press ENTER.
e) You will see that you may install DGIS drivers that will display
large or small fonts when Windows is run. Choose the driver
appropriate for your display resolution and press ENTER.

procedure.
Changes from previous release of BETA driver for DGIS Windows
-------------------------------------------------------------
This new release now is able to display TrueType fonts correctly whereas
the previous versions could not. We would appreciate any bug reports of
problems with fonts, especially in standard mode where some possible
problems have been detected.
(email bug reports to: geoffs@gss.com)
Configuration Utility for the Windows DGIS Driver
-------------------------------------------------
There are a number of flags which the user can specify in the
WIN.INI file which affect the way in which the Windows DGIS
driver will behave. These flags are detailed below.
To make it easier to set the values of these flags a configuration
utility, DGISCFG.EXE, has been provided. The configuration utility
is a Windows application which can only be run from within the
Windows runtime environment. There is a help facility built in to
the utility which explains things in more detail.
To install the configuration utility, copy the files DGISCFG.EXE and
DGISCFG.HLP to a directory on your hard disk. You should then install
DGISCFG.EXE as an icon in your Windows program manager desktop.
DGIS flags in the file WIN.INI:
-------------------------------
DitherSize= 0/1 0 = 4x4 dithers <default>
1 = 8x8 dithers
4x4 dithers are faster than 8x8 dithers, as they go
through a special case path in DGIS. 8x8 dithers look
a little nicer.
HatchSize= 0/1 0 = 4x4 Hatches <default>
1 = 8x8 Hatches
4x4 hatches are faster than 8x8 hatches, but 8x8
hatches are much easier to see at high resolution.
NumFonts= N N = number of fonts to cache on remote side
<Default of 5>
Number of fonts to cache on the remote. If your
card has lots of memory, you can cache more fonts
for faster operations. If your card has little
memory, cache fewer fonts.
Fill= 0/1/2 0 = DGIS does all polygon fills <default>
1 = GDI does XOR polygon fills only
2 = GDI does all polygon fills
DGIS does not do polygon fills in the same fashion
as Windows. Dgis fills the right and bottom edge.
This creates problems during XORs of polygons. If
you want speed, allow DGIS to do the polygons. If
you want correct XOR's, set the GDI XOR. If you want
100% correct polygons, use 2 (GDI does all).
WideLines= 0/1 0 = DGIS draws wide lines
1 = GDI draws wide lines <default>
GDI draws wide lines that differ in style from the
way in which DGIS draws wide lines (caps and joins
between line segments will differ). For correctness
you may want GDI to draw all wide lines.
StretchMode= 0/1/2 0 = DISCARD data on compress <default>
1 = AND data on compress
2 = OR data on compress
When stretching images, there are 3 methods of
handling compression of bits. Choose the method
you prefer. Due to a problem in the specification of
the StretchBlt driver function, GDI does not pass the
driver the current StretchBltMode. The DGIS driver
only stretches screen to screen objects so the normally
correct mode is DISCARD (GDI calls this COLOR_ON_COLOR)
but this can be altered via this switch.
NOTE: Corel Draw v2 has been found to display
certain elements of its dialog boxes more correctly
if the StretchMode is set to 2.
ScanBuffer= N N = size in bytes of scan buffer (2K min)
This area is used to buffer GDI's output calls,
allowing DGIS to send blocks of data to the remote.
If you are running in protected mode, 16K is the
recommended minimum. The default is 2K for real
mode, and 16K for protected mode.
Stack= N N = size of stack to allocate for DGIS
When in real mode, DGIS must have a larger stack than
GDI provides. This specifies how large of a stack to
allocate for DGIS. Generally you can leave this
parameter alone.
StyledLines= 0/1 0 = DGIS draws all styled lines <default>
1 = GDI draws all styled lines
Lines that are not solid, but contain a series of line
segments with interspersed gaps, can be drawn by DGIS
or can be allowed to be emulated by GDI. DGIS styled
line drawing is the fastest and for most instances is
100% correct and is thus the default. In a small number
of cases DGIS styled line drawing will produce results
which are not 100% compatible with the way in which
GDI would draw the styled lines. These cases usually
involve redraws of segments of the screen that contain
styled lines which have been overlaid by other windows
and subsequently "unhidden". If you encounter these
cases you may choose the GDI drawing option to get 100%
correct results.
GrafConfig= N N = Graphics Configuration to connect to.
If your DGIS adapter supports multiple configurations,
this switch informs the DGIS Windows driver which
configuration to use.
PackedPixel= 0/1 0 = 8 bit configurations run in planar mode
1 = 8 bit configurations run in packed mode <default>
The DGIS Windows driver supports planar or packed modes
for 8 bit configurations. Packed pixel is the default,
and most applications will run faster with the driver
in this mode.
ClearAtExit= 0/1 0 = don't clear hires screen at Windows exit <default>
1 = clear hires screen at Windows exit
Some users, especially those running dual monitor
configurations (DOS on one monitor, Windows on the
other), find the retension of graphics image data
on the high resolution monitor after having exited
Windows to be annoying. Setting this flag to 1
causes the high resolution screen to be cleared
before Windows terminates.
InhibitRepaint= 0/1 0 = repaint desktop after return from fullscreen
DOS session <default>
1 = inhibit repaint of desktop after return from
fullscreen DOS session
The repainting of the Windows desktop after switching
back from a fullscreen DOS session in enhanced mode
is not necessary on most DGIS cards since the high
resolution framebuffer is independent of the DOS
screen framebuffer. For these DGIS cards the repaint
of the desktop can be inhibited by setting this flag
to 1.
