GDS7543 WIN95 Driver Release 2.20
-----------------------------------
GD7543 rev BC/BF silicon
Changes from 2.10a to 2.20
==========================
-Fix problems. See Problem Solved below.
-Copy DVIDEO.DLL to system directory and change 754x.inf to include this
file so MVA can be enable while running AVI via Media Player.
-Add Direct Draw support with MVA enabled.
-Add hot-key display switching without using power.drv.
-Add support for the Refresh Utility in Japanese, Korean, Traditional Chinese
and Simple Chinese.
Resolutions & Colors supported
===============================
640x480x256
640x480x64k
640x480x16M
800x600x256
800x600x64k
1024x768x256
1024x768x64k (2 Meg video memory only)
1280x768x256 (2 Meg video memory only)
Problems fixed
=============
-In some APM implementation, hot-key switching display may cause a blank
panel screen. New resolution is to bypass power.drv.
-Changing from 640x480 or 800x600 256 colors modes to 1024x768 256 color
results in desktop background pattern being duplicated on right and bottom
screen in CRT only mode.
-If a windowed DOS prompt is open in any non-TV display mode, switching to
TV causes a display corrruption.
Known Problems
==============
-In 800x600 64k colors, user is able to set new monitor refresh but the
new refresh does not take effect.
Win95 Driver limitation
=======================
-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.
