- 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 disk:
-
- 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 INSTALL
- disk)
-
- 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) Insert your Windows 3.1 Driver for DGIS floppy into drive A and
- press RETURN.
- 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 RETURN.
- 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).

- 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.
