No need to continue with rest of steps if you restart the windows. 18. Close the ‘properties’ dialog box if it is open. 19. Close the ‘Device Manager’ applet. 20. Close ‘System’ applet 21. Close Control Panel. 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.

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 All the functions below have been altered to allow the Durango API calls to be used miniport\Gxdrv.c functions:GXSetCursorPos GXCursorOn GXCursorOff miniport\GXTIME.C functions:GXSetDisplayMode miniport\GXDEFS,H Since all Durango API calls are in #ifdef DURANGO Durango had to be defined in this file display\Video.h Since all Durango API calls are in #ifdef DURANGO Durango had to be defined in this file display\ddraw.c functions:DdScrToScrBlt DdScrToScrBltTrans display\Textout.c functions:TextOutGX TextOpaqueRect display\STRIPS.C functions:stripSolidDiagonalHorizontal stripSolidDiagonalVertical display\Paint.c functions:PaintSolid display\LINETO.C functions:StrokeLineSegment LineToTrivial display\LINES.C functions:bHardwareLine display\Gx.d functions:GXSolidFillRectangle display\Bitblt.c functions:Fb8 Fb8Dest8 Fb8Src1 Fb8Src1Dest8 Fb8Pat1Src1 Fb8Pat1Src1Dest8 Fb16 Fb16Dest16 Fb16Src1 Fb16Src1Dest16 Fb16Pat1Src1 Fb16Pat1Src1Dest16 ScrnToScrnBlt ScreenBlit Bugs Fixed ---------- None Listed Known Errata ------------ None Listed ----------------------------------------------------------------------------- 01/08/1999 Version 5.05.4.1018 ---------------------------------------------------------------------------- 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. Files Changed -------------- None Listed Bugs Fixed ---------- None Listed Known Errata ------------ None listed ------------------------------------------------------------------------------- 11/12/98 Version 5.05.4.1017 ------------------------------------------------------------------------------- Functional Changes ------------------- Add GetScanLine feature to direct draw support.

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.)
