QA Notes
========
-Because Cirrus Logic did not receive a full functional notebook system
at the time of this software release, QA cannot verify any features that
require interaction between the system BIOS nad the VGA system.
Problems Fixed from release 2.10 to 2.10a
=========================================
-When select refresh rate from panel only or SimulSCAN, display type is
switched to CRT only. PDR#3336
Known Problems
==============
-In some APM implementation, hot-key switching display may cause a blank
panel screen.
-In 800x600 64k colors, user is able to set new monitor refresh but the
new refresh does not take effect.
-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.
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.
