Control Panel Extension

A control panel extension is provided to configure certain parameters of the
driver like Compression, DDC, Panel Support etc. The details of these parameters
are as follows.

Registry Settings
The driver behavior depends upon the way it has been configured. This
configuration mechanism is possible by registry settings. Given below are
the registry settings that change the behavior of the driver.

DDCEnabled
This option enables the driver to query the monitor for the best-supported
resolutions. This will be disabled automatically if flatpanel support is
requested.
This option is enabled by default.

PanelSupport
This option enables driver output to a flatpanel instead of a CRT (default).
This option only configures the output as flatpanel and doesn't describe the way
the hardware has been initialized. If this option is enabled the DDC query is
disabled.
This option is disabled by default.

PanelInitInBIOS
This option instructs the driver to use the flatpanel initialization done in the
BIOS. Tthe BIOS is queried to determine the supported flatpanel resolution. The
BIOS timings are not touched. This option requires the PanelSupport option to also
be enabled in order. This option overrides the Platform option.
This option is enabled by default.

Platform
This option enables the driver to use the flatpanel initialization done by
the driver. Here the hardware is queried to find out the supported flatpanel
resolution. The jumper settings on the board dictate the desired resolution
and works only on National Development Platforms. The NSC Boards supported
today are Centaurus and Dorado Platforms ONLY. This option requires PanelSupport
to be enabled and the "PanelInitInBIOS" option to be disabled.
This option is 0 by default.
________________________
|Platform | Value |
|----------------------|
|Centaurus | 0 |
|Dorado | 1 |
------------------------

VIPInterleave
This option is relevant only on single-chip systems. It is used to control the
interleave scheme used when displaying data from a videport. This option requires
a VIP IRQ to be specified.

FieldInvert
This option is relevant only on Single-chip systems. It is used to select the
polarity of incoming videoport data. When this setting is 0, the videoport odd
field is assumed to be the first field.

VIPIRQ
This options selects the IRQ that is allocated to the videoport. It cannot be
a PCI interrupt or an interrupt that is used by a system device (such as the
parallel port or the system timer). If no IRQ is available, only Bob
deinterlacing will be available.

BUILD INSTRUCTIONS
-----------------------------------------------------------------------------

Windows XP Driver Build Instructions

1. Install Windows 2000 or later on your system.
2. Install the Windows DDK 2527 on your system.
3. Create a folder called ‘vss’ anywhere in the system. 'vss'
may be replaced with any name.
4. Copy the WinNT40\gx Directory tree from Video\Customer Releases\drivers to
vss\drivers\winnt40\gx
5. Download the companion Durango from Video\Customer Releases\durango\gfx to
vss\durango\gfx
6. Download the Flat panel code in the panel folder from Visual Source Offsite to
vss\drivers\winnt40\gx\panel.
7. Download the DDC code in the ddc folder from Visual Source Offsite to
vss\drivers\winnt40\gx\ddc
8. Open the Free Build environment.
9. Set WINXP environment variable using the following command :
set WINXP=1
10. Change the directory to vss\drivers\winnt40\gx

11. Compile using:
C:\gx>build -cf

12. After the build is complete, copy the following files onto a floppy:
- gx.dll found in gx\display\objfre\i386
- gxm.sys found in gx\miniport\objfre\i386
- gx_winxp.inf found in gx\release OR
- gx_winxp_fp.inf found in gx\release for flat panel support

13. Build the control panel display extension dll as per instructions in 'readme.txt' in CPlApp

14. You are now ready to install. Please go to Installation.

Added Durango Interface to NT4.0 graphics driver.

Files Changed

The name Cyrix was changed to National Semiconductor as well as the
copyright date in the following files:
Vga.h, Gxdrv.h, Gxdrv.c, Debug.c, Video.h, ddvideo.c, ddraw.c
ddgx.h, cognaac.h, Textout.c, RES.RC, Pointer.c, Paint.c, Gx.h
Enable.c, gx.inf

The driver now supports the Durango API. All calls to the Durango API
are enclosed in the code #ifdef DURANGO

miniport\SOURCES
This was changed to allow the original Nt40 driver to be able to
look into the Durango folder as well as the Durango.C file

display\SOURCES
this was changed to allow the original Nt40 driver to be able to
look into the Durango folder as well as the Durango.C file

GXCursorOn
GXCursorOff
miniport\GXTIME.C
functions:GXSetDisplayMode

miniport\GXDEFS,H

Functional Changes

Respect the miniport setting for screen stride (pitch) rather than trying
to compute it in the display driver. Previously there was a problem with
16 bpp modes in the WHQL tests where NT assumed the pitch was 1024 because
the math works out, but SoftVGA set the pitch to 2048.

11/10/98 Version 5.05.4.1016
---------------------------------------------------------------------------------

Functional Changes
------------------
Record new framebuffer offset when flipping overlay surface. This bug
caused overlay surfaces (most noteably Overfly) to not be destroyed
sometimes.
Change DDBlt code to handle blits from one FourCC surface
to another. This gets us through the FourCC tests on WHQL for
PC98.
When calling EngBitBlt to render for us, pass it the original
surface pointer instead of the created surface pointer. The
PC98 NT 5.0 tests croaked on this for some reason.
Remove some debugging prints that could, in rare cases, cause the
driver to read data that it doesn't have access to. (Applies only
to debug versions.)
