VALIDATION NOTES 
-----------------------------------------------------------------------------
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:
* 1028 Win2k Graphics: WinBench 99 Video test reboots system   Errata

When the WinBench 99 Version 1.0 or 1.2 video test is run the system would 
reboot approximately 5 minutes into the test. This only occurred in WinBench.
No problems were seen with playing video files (AVI, MPG, MOV) with Windows 
MediaPlayer

*Notes
1. 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. 

Windows NT/NTe

*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:
* 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.

* NT/NTe 1028 Graphics - Overlapping memory ranges NT/NTe

When the Windows NT/NTe 1029 Graphics driver is installed, there are two 
errors that appear in the event manager. The errors are as follows:

A conflict has been detected between two drivers which claimed two 
overlapping memory regions. Driver Reserved, with device , 
claimed a memory range with starting address in data address 0x28 and 0x2c, 
and length in data address 0x30. 

A conflict has been detected between two drivers which claimed two 
overlapping memory regions. Driver GX, with device 
, claimed a memory range with starting address 
in data address 0x28 and 0x2c, and length in data address 0x30. 

This has not shown to cause any issues with the operation or functionality 
of the driver. An event manager warning message may appear on boot up, 
depending on system configuration, stating that a service or driver has 
failed to load and to see the event log.

* NT4 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. 

3. NTe KDF file installation
When installing the KDF for use in Embedded NT, the DLL and SYS files must 
be located in C:\GX directory or the driver will not install.

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.)
