VW701321.DOC - Windows Video Diskette - IBM ThinkPad 701
Chips and Technologies, Inc.
Release Notes
655XX Display Driver Package
Windows 3.1/DOS
Revision: Version 3.2.1
Release Date: August 1, 1995
=======================================
WINDOWS DRIVERS
1. Fixed a General Protection Fault in CorelPaint 5.0 when
KAI's PowerTool Filter 2.0 is run using the 16M color (24bpp)
driver.
2. Fixed an error in the Fatal Error exit code which was
causing a stack imbalance.
3. Fixed a "Not Enough Memory" error in PaintBrush by adding
an option that disables the Fatline & Polygon driver
function in all the drivers when drawing an Ellipse of
height/width of 3 pixels with a pen width of 2/3 pixels.
NOTE:
CHIPS' driver implementation of the Fatline and Polygon
driver function is different from Microsoft's driver
implementation. To fix the above problem, make the
following change in the [DISPLAY] section of the
SYSTEM.INI file:
[DISPLAY]
. . .
Fatline=0 ;disable fatline driver implementation
Polygon=0 ;disable polygon driver implementation
By default, the driver implementation for the
Fatline/Polygon function is enabled. There will be some
impact on performance by disabling the Fatline/Polygon
driver implementation.

NOTES - WINDOWS DRIVERS
1. These drivers support the linear frame buffer. Please note
the following points regarding the Windows 3.1 linear
drivers:
Continued improvement in features and performance.
One driver per color depth supports multi-spatial
resolutions.
Added pen compliance.
PC Video aware.
Supports DCI (primary surface).
Supports panning if driver resolution is more than the
display size of the panel.
Supports display switching using a Control Panel Applet
and/or with a hot key if the OEM BIOS meets the CHIPS
specification for display switching.
NOTE: Display switching is not allowed if Windowed VM
has focus.
WINMEM32.DLL needs to be present in the SYSTEM
directory.
These drivers cannot run in Windows standard mode
(WIN/S or WIN/2).
2. The following list describes the Windows 3.1 driver filenames
and resolutions:
LINEAR4.DRV: 16 Color Multi Res, Pan, Pen, Big
Cursor, Display Switch
LINEAR8.DRV: 256 Color Multi Res, Pan, Pen, Big
Cursor, Display Switch
LINEAR16.DRV: 32K/64K Color Multi Res, Pan, Pen, Big
Cursor, Display (65535/540 only) Switch
LINEAR24.DRV: 16M Color Multi Res, Pan, Pen, Big
Cursor, Display Switch (65540 only)
The following drivers function with the F65545 only
VIDGX4.DRV: 16 Color Multi Res, Pan, Pen, Big Cursor,
Display Switch
VIDGX8.DRV: 256 Color Multi Res, Pan, Pen, Big
Cursor, Display Switch
VIDGX16.DRV: 32K/64K Color Multi Res, Pan, Pen, Big
Cursor, Display Switch
VIDGX24.DRV: 16M Color Multi Res, Pan, Pen, Big
Cursor, Display Switch
3. Some applications, such as CorelDraw, PhotoStyler and
Fotoman, assume 16 color drivers are VGA planar drivers and
renders the image in the planar format. These applications
do not correctly interpret Plane and BitsPixel information
returned by the driver, and are not displayed correctly in
our 4bpp packed pixel driver (LINEAR4.DRV).
The following table compares information returned by two
different formats for 16 color drivers:
VGA.DRV LINEAR4.DRV
(Planar) (Packed)
BitsPixel 1 4
Planes 4 1
Colors 16 16
4. CHIPS' driver implementation of the Ellipse and Round
Rectangle function is different (one pixel off) from
Microsoft's driver implementation. CHIPS' RoundRect
driver implementation causes a problem where the bottom
line disappears in TCALC.EXE of the ESS Audio card. To
fix this problem, make the following change in the
[DISPLAY] section of the SYSTEM.INI file:
[DISPLAY]
. . .
RoundRect=0 ;disable round rectangle driver
implementation
Ellipse=0 ;disable ellipse driver implementation
By default, the driver implementation for the
Ellipse/RoundRect function is enabled. There will be some
impact on performance by disabling the Ellipse/RoundRect
driver implementation.
5. The following anomalies exist with drivers in the industry
other than CHIPS drivers:
Windows 3.1 MPLAYER.EXE has a problem when displaying
HELP with high color and true color drivers. This
problem is fixed in Windows 3.11 MPLAYER.EXE.
Windows 3.1 Paintbrush has a problem with a black box
appearing when pasting a DIB and immediately flipping
the object horizontally. This problem is in the GDI
and appears in most 256 color drivers.
Windows 3.1 Paintbrush has a problem with low memory
when printing a color image in high color drivers.
This image is successfully printed by doing a cut-and-
paste to Word for Windows.
Windows 3.1 HELP screen has a problem with text
appearing dark (black) instead of green in high color
drivers.
Windows 3.1 DCT ROP3 test has a problem with the 32k
color(15bpp) driver. This problem occurs with other 32k
color drivers.
The TDW(Turbo Debugger) in Turbo C++ for Japanese
Windows 3.1 causes an error which states "Illegal Video
Mode".
Quick Recorder (Video for Windows) has a problem
displaying small fonts in high & true color drivers.
The application does not allocate sufficient memory for
the small font, but it successfully displays large
fonts.
