- 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.
