21. Close Control Panel.
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 supported requested.
By default this option is enabled.
PanelSupport
This option enables the driver to output on to flatpanel instead
of 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.
By default this option is disabled.
PanelInitInBIOS
This option enables the driver to use the flatpanel initialization
done in the BIOS. Here the BIOS is queried to find out the supported
flatpanel resolution.
This option needs the PanelSupport option to be enabled.
This option overrides the Platform option.
By default this option is enabled.
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 needs the PanelSupport
option to be enabled, for this option to be used disable
PanelInitInBIOS.
The default value is "0".

Windows 2000
*The following issues were noted with this release:
NONE
*The following previous issues were still seen with this release:
NONE
*The following issues are errata and will not be fixed:
* 110.18 3 WinBench 99 Video Cases fail on Centaurus
When WinBench 99 version 1.0 or 1.2 is run the Windows Media player
codecs must first be updated as per Ziff Davis or there will be failures
in testing. The updated codecs can be downloaded from www.ligos.com. During
the Video test in either version of WinBench there were problems with the
playback of 3 AVI files even with the updated codec and only when they were
played at 100% zoom on the Centaurus platform.
The files are as follows:
cp640s9.avi
in640s9.avi
i4640s9.avi
The corrupted video playback is only seen when any of these three files
are played at 100% zoom. All other zoom levels playback correctly. No other
AVI files that were run showed the playback corruption.
* 110.35 WinBench 99 Video Tests fail in 640x480 and 800x600
When WinBench 99 Version 1.0 or 1.2 video test is run in 640x480 or 800x600
at 75Hz refresh rate there is video corruption seen on the screen.
The failures are as follows:
The following cases fail in 800x600x8 @ 75 Hz and 800x600x16 @ 75Hz
Video/Action, Cinepak, 640x480, 30fps, 900 KB/S, Zoomed
Video/Action, Indeo 3.2, 640x480, 30fps, 900 KB/S, Zoomed
During the above two cases the screen is spilt in two with the video playing
in both screens. The left half of the screen is slightly behind the right
half and the left half is obscured by horizontal black lines.
Video/Action, Indeo 4.1, 640x480, 30fps, 900 KB/S, Zoomed
This case exhibits the same failure as above but now the only colors showing
are shades of blue and green lines obscure the left half.
Video/Action, MPEG-1, 352x240, 30fps, 150 KB/S, Zoomed
Video/Action, MPEG-1, 352x240, 30fps, 300 KB/S, Zoomed
During these last two cases there is a pink line running across the top of
the screen.
The following cases fail in 640x480x8 @75 Hz and 640x480x16
Video/Action, Cinepak, 320x240, 30fps, 300 KB/S, Zoomed
Video/Action, Indeo 3.2, 320x240, 30fps, 300 KB/S, Zoomed
Video/Action, Indeo 4.1, 320x240, 30fps, 300 KB/S, Zoomed
Video/Action, MPEG-1, 352x240, 30fps, 150 KB/S, Zoomed
Video/Action, MPEG-1, 352x240, 30fps, 300 KB/S, Zoomed
During the above cases the left 1/4 of the screen has horizontal black lines
and there is a white line across the top of the screen.
Video/Action, Cinepak, 640x480, 30fps, 900 KB/S
Video/Action, Indeo 3.2, 640x480, 30fps, 900 KB/S
Video/Action, Indeo 4.1, 640x480, 30fps, 900 KB/S
Video/Action, Cinepak, 640x480, 30fps, 900 KB/S, Zoomed
Video/Action, Indeo 3.2, 640x480, 30fps, 900 KB/S, Zoomed
Video/Action, Indeo 4.1, 640x480, 30fps, 900 KB/S, Zoomed
During the above cases the left 3/4 of the screen is a mass of green and blue
dots.
These issues were not seen when any video files that were played with Windows
MediaPlayer including the files that showed corruption in WinBench.
*Notes
1. Overfly fails YVYU surface type at any resolution and color depth
When the Overfly test is run from DCT 300 or HCT 9.52 the YVYU surface test
fails at all resolution and color depths on all platforms. This is due to the
Overfly test not supporting the YVYU mode even though the mode shows up in
the program as a testable mode.
This was orginally seen in issue 110.15 - Overfly YVYU surface type is
corrupt in 640x480 & 800x600
2. Video playback at 1280x1024x16bpp
Multimedia videos (AVI, MPEG, MOV) cannot be displayed at 1280x1024x16bpp
due to hardware limitation. The system uses all 4MB of RAM allocated to the
graphics adapter, causing the media player to fail.

VALIDATION NOTES
-----------------------------------------------------------------------------
* Issues/Errata
These issues are seen with this driver.
* NT/NTe Graphics driver fails WHQL DCT Overfly test
- This issue reappeared in this version of the driver. The overfly
test checks the flipping support of the driver.
* NT4/NTe Graphics v1025 Wallpapers change color when a window is opened in
8-bit color
- This issue is still being looked into.
* NT/NTe 1025 Graphics Video corruption when playing videos
- When some AVI's or MPG's are played in windows media player the
video output of the player is corrupted or discolored and when the
media player is moved across the screen the video playback remains
at its last location.
* Overfly YVYU surface type is corrupt in 640x480 & 800x600
- When the overfly test is run in YVYU mode at 640x480 or 800X600
the butterfly box that appears is multicolored and corrupted.
* NT4/NTe 1026 Graphics driver all overfly surface types fail above 800x600
- When the overfly test is run in resolutions above 800x600 the test
fail with no graphic output from the program.
* WinBench 99 Video Tests fail on Dorado
* 3 WinBench 99 Video Cases fail on Centaurus
* WinBench 99 Video tests hang in 1024x768 on Centaurus
* Tddraw fail WHQL DCT Short Regression testing on Centaurus in 1280x1024x16
- This issue is still being looked into. It may be related to the
amount of video memory that is allocated to the video adapter.
These issues are errata for this driver.
* Foxbear will not run in direct draw modes below 640x480x8
The NT4 portion of the code was tested for compatibility with VSA1 and VSA2
in this validation cycle. The VSA1 testing was performed on a Unicorn system.
The driver build used in testing was for use with a CRT. Testing of the Flat
Panel build of this driver was not done because no flat panels were available
for use in testing.

* 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.)
