======================================
Prior to installing these drivers, Make sure that Windows is using
the VGA driver that was included with Windows. If Windows is using any other
driver, reconfigure Windows using Setup from DOS or from within Windows.
1. Insert the 7543 Windows 3.1x Driver Installation diskette into A: or B:.
2. Run INSTALL.EXE on the diskette from Windows File Manager.
3. Follow instructions on screen to complete the installation process.
4. A WinMode program will pop up to ask user to select options. Select
any desired choice to fit your preference.
OS/2 2.1x Warning
=================
If you are installing these windows drivers into WIN-OS/2 2.1x, at the end
of this installation, a WinMode utility program will pop up to allow you to
choose different colors and resolutions. MAKE SURE you select the
"OS/2-Windows" option in the Operating System group.
Known Problems
==============
The following items were discovered during testing against the test plan
documented in the release notes:
-Performing a video MPEG playback using the XING mpeg player v1.1 and
zooming the video window causes video corruption. PDR#3465
-Double video windows shown while using Ctrl-2 to zoom the video playback
windows in Xing MPEG in 640x480x64K mode. PDR#4103
-In 16 million colors, open a DOS full screen, set to standard modes
0 and 1 and then press Alt-Enter, and Enter again, the display is corrupted.
-With 800x600 DSTN panel, set to some standard video (ie. 0H,1H) in DOS full
screen, Alt-Enter few times to toggle between PM and DOS full screen
sometimes show few lines of big characters on screen or blank display.
-Horizontal lines flash across the panel when switching between windowed
DOS session and DOS full screen. - PDR 2436
-In TV display mode only, application name title is not shown while pressing
Alt-Tab in DOS full screen. - PDR 2788
-In 16M colors mode, open a windowed DOS session then warm boot machine
would corrupt screen but pressing Esc recover the screen image.
Windows 3.1 driver limitation
=============================
-Japanese and some Asian Windows 3.1x do not support change-res-on-fly.
Changing a new resolution in Winmode will trigger Windows reboot.
-Execute Change-res-on-fly and part of a dialogue box remains after importing
Microsoft Windows Metafile (*.WMF) in Adobe Illustrator 4.0. This is a
problem with application not knowing new res. has taken effect. PDR#2796
-Use Winmode to switch from low res. to high res with a file open in Adobe
Illustrator 4.0, dragging the scroll bar outwards will leave image of
the scroll bar. This is a problem with application not knowing new res.
has taken effect. PDR#2821, PDR#2822
-Changing display mode or changing resolution-on-the-fly (ROF) sometimes
results in an icon missing or distorted image on screen when AfterDark is
loaded in the background. This is due to AfterDark application not
compatible with some features in the driver.
-Image is incompletely redrawn after switching from low resolution to high
resolution and GPF warning usually occur in Adobe Illustrator 4.0. PDR 2822
-After resolution-change-on-the-fly (ROF), user can not write letters in CIC
Handwriter for Windows.
-A GPF is generated when running Mediamatic Player in SimulSCAN with DSTN
SVGA panel. This is a Mediamatic application issue. - PDR 1767
-Mediamatic MPEG Arcade Player shows color drop-off in video clip. This is
a Mediamatic application issue. - PDR 2609
-Large font remains after switching back from TV to any non-TV display mode.
This is by design because Windows characters look better in large font in
TV and WinMode currently has no way to save the font size before the TV
switch. The users just have to be made aware that they need to change back
to small font if that is what they desire after switching back from TV mode.
This can be accomplished by selecting the small font radio button before
pressing OK from the main WinMode dialog- PDR 2732
