GD7548 WIN95 Driver Release 1.40

the drivers.

Known Problems
==============
-When you play a HW MPEG (ie. Sigma Design's REALMagic or Margi To Go,
etc.) in a DSTN panel, the video playback window initially comes up
as pink or black. This is due to VPM and Clients communicatation
problem. If this problem is encounter, use the mouse to click on any
where on the playback window and the clip would come up fine.
-With XGA panels, some noise appears on the left edge of the video
windows in all display type when MVA is on.
-Color is corrupted in Video windows when resizing SW MPEG playback with
XGA panel in 800x600x256c. PDR#8075
-Double image of MPEG file appears when toggling between 1x and 2x size
using Mediamatics. PDR#7000
-Continue resizing the mediamatic playback window causes system to hang up
intermittenly. PDR#7108
-Hotkey display switch causes error message in 1024x768x256c and 800x600x64K
modes in some systems. PDR#5432
-When expansion is enabled, VPM errors will occur while performing a video
playback on either SimuSCAN or lcd only display using an 800x600 TFT
panel.
-VPM errors will occur when performing video playback on an XGA, 1024x768,
TFT panels using Margi's MPEG to go card.
-Toggle between DOS session and PM after setting to some low resolution
standard modes causes unpreditable results.
-Some problems encountered running different MPEG decoders.
-Dashed line (dark and light pixels) sometimes appears when capture first
enabled. Cannot find software cause.
Win95 Driver limitation
=======================
-If you are running any Direct Draw game modes that is lower than 640x480
(ie. 640x400), display switching is not allowed.
-If you are playing video clips and what to change resolution or color depth,
it is recommended to stop the playback first else you would see unpredictable
result.
-If you are running a graphic resolution that is different that Direct X
game mode resolution, (ie. 800x600 Windows environment and 640x480 Foxbear),
a hot-key display switching then followed by exiting Foxbear game would drop the entire
Windows environment to Foxbear's resolution which was 640x480 instead of
800x600.
-If you want to use hot-key to switch from a MVA-capable display type to a
display type that is unable to handle MVA on, it will revert back to MVA off.
-Once changing from MVA on to MVA off, the only way to get MVA again is
to restart the playback in a configuration that allows MVA.
-CR20[5] cannot be set to 0. We advise strongly that customers call BIOS
function to implement standby instead of changing this bit through other
means. PDR#7808
-Case 35 failure in DCT part of TDDRAW. MS issue. PDR#7172
-If you try to change resolution while DDraw game is being played (ie.
Foxbear), Win95 may display an error message and terminate the game without
prompting user to save. PDR#7138
-Opening multiple video playback windows may cause GPF because there is
no support for this feature.
-In TV mode, open any application shows that bottom of the application is
chopped off because TV uses 640x400 resolution mode.
-Switching from any non-TV display type to TV requires Win95 to restart.
This is by design.
-In TV mode, the Win95 logo screen got shifted down because TV uses 640x400
resolution mode.
-VPM error message "use a lower resolution" will occur when performing HW
MPEG video playback (eg. Sigma's REALMagic, etc.) using ZV port in some
systems configuration. This is because the clients software do not handle
the VPM return codes properly when memory bandwidth is encountered.
