- 1. Using the Windows SETUP Program to Change Drivers
- =================================================
- If you use the Windows SETUP program to select or reselect the
- DXP driver (either in Windows or from the DOS command line), always
- elect to use the CURRENT installed driver unless you have a new
- S3 Windows driver diskette. If you need to re-install the original
- driver included with the your board, run the WinSetup program on
- the diskette included with your S3 graphics accelerator.
-
- 2. Chinese/Japanese/Korean/Thai Editions of Microsoft Windows
- ==========================================================
- The DXP driver and Control Panel are fully compatible with these
- foreign language editions of Microsoft Windows. If you encounter any
- problems, please let us know. (See also notes 4 and 5 below.)
- Sorry, IBM's version of Japanese Windows is NOT supported; you are
- limited to the 800x600x16 color mode supported by IBM's SVGA driver.
-
- 3. True-Color Display Configurations: 24bpp and 32bpp
- =========================================================
- For 2MB and 4MB memory configurations, S3 defaults to 32bpp in true
- color configurations. The DXP control panel, however, offers you a
- choice of either 24bpp or 32bpp display modes for added flexibility
- (assuming the chipset supports both 32bpp and 24bpp packed pixel mode).
- If you encounter a problem using 32bpp (e.g., corrupted icons or
- other resources), try switching to a 24bpp color depth; if this works,
- you should be able to safely reselect 32bpp using the DXP Control
- Panel. The 32bpp configuration offers roughly double the performance.
-
- 4. Japanese Windows Configurations - Special Notes
- ===============================================
- Due to the heavier resource requirements, S3 does NOT support the
- following display modes under Japanese Windows:
- 1024x768x16.7M colors 1280x1024x32k colors
- 1280x1024x65k colors 1280x1024x16.7M colors
- 1600x1200x32k colors 1600x1200x65k colors
- However, since problems in these display modes are largely application
- dependent, the DXP Control Panel gives you the option of selecting
- these display modes if your chipset and memory configuration support
- them.
-
- Note also that Japanese Windows is incompatible with the resolution of
- 640x400 pixels offered by the DXP to provide true color with Trio64-based
- boards that have only 1MB of memory.
-
- 5. DCI Support
- ===========
- Full DCI support requires Video for Windows 1.1d or a later version. If
- you are using an earlier version of VfW, you may encounter problems.
-
- 6. Adding a Refresh Rate Setting to the AUTOEXEC.BAT File
- ======================================================
- The DXP Control Panel gives you the option of adding your refresh rate
- setting to the AUTOEXEC.BAT file so that the system will "remember" your
- preference each time it starts. This setting is added to the beginning
- of your AUTOEXEC.BAT file to ensure it is called by systems with multiple
- DOS configurations. Because the S3REFRSH.EXE program appends its calls to
- the end of the AUTOEXEC.BAT file, it is possible for the DXP setting to be
- overridden by an S3REFRSH.EXE call.
-
- 7. MPEG Playback, Benchmarks and System Power Management
- =====================================================
- If your VIEWTOP Graphics Accelerator was bundled with a software MPEG driver,
- you may find it necessary to at least temporarily disable your system's
- power management features via your system BIOS Setup program. Since many
- advanced power management schemes monitor only the keyboard, communications
- ports and PS/2 port for activity, it is possible for your system to enter
- "doze" or "standby" mode during MPEG playback - power saving states which
- will seriously affect playback performance. You will know if you need to
- change your system's power management setup if MPEG playback begins
- smoothly and then, after a certain period of time, begins to "jerk";
- then if smooth playback resumes after moving the mouse or pressing a key
- on the keyboard, the reason for the degeneration in playback is that your
- system entered a power saving state after sensing prolonged inactivity on
- the keyboard and mouse ports. Note that power management adversely affects
- prolonged benchmark tests in the same way.
