Release Notes
65545-PCI  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.
