S3 Considerations after installing XR06200
S3 FUNCTIONAL RESTRICTIONS
---------------------------
After Dark** for Windows** images that move from
left to right do not perform properly at 640x480x16M resolution.
To avoid a General Protection fault while loading
Ventura Publisher** for Windows be sure it is in one of the
256 color resolutions.
To avoid a trap in Lotus** 1-2-3** for OS/2 do not
attempt to run the program at 16.7 million colors.
WordPerfect** 5.1 and 5.2 for Windows produce a
general protection fault when the "Print Preview"
option is selected while using
800x600x64K or 600x480x16 million color mode.
Users of the software motion video feature of MMPM/2
should expect satisfactory results in 256-color modes.
However, in 64K-color modes, users of the feature will
experience unusual MMPMCS results. The software motion
video feature is not supported in 16 million color modes.
In addition, the software motion video feature will
take advantage of a 1MB aperture on video adapters and
systems where it is available to improve the performance
of video playback in 64K-color modes. For those systems
with nonstandard locations, the actual physical address of
the aperture must be provided in the following CONFIG.SYS
statement:
SET VIDEO_APERTURE=xxxh
Where "xxx" is a hexadecimal value in units of 1MB,
representing the actual physical address to map to the aperture.
For example, the IBM PS/ValuePoint Systems must have the
statement:
SET VIDEO_APERTURE=400h
To use a physical address at 1GB.
If you are using the 256 color mode, and your desktop
appears to be darker than other color modes, you must
edit the SVGADATA.PMI file located in the \OS2 directory.
Change the following statement from:
HI-COLOR DAC by ....
to:
HI-COLOR DAC by unknown
To make the changes effective you must reboot your system.
