2.0  Compatibility
__________________

This graphics-accelerator device driver is compatible with OS/2
2.11, and OS/2 Warp 3.0.

3.0  DDC Monitor Support
_______________________________________

VESA Display Data Channel (DDC) 1 and 2B protocols are supported,
allowing similarly enabled computers and operating system software
to identify the monitor and its capabilities.  This device driver
automatically detects DDC monitor capabilities and sets the display
to the maximum refresh rate supported by the monitor.  If, after
installing this device driver, you switch from a non-DDC monitor to
a DDC monitor or switch to a different DDC monitor, you must run the
DDC Display Setup program in the System Setup folder.

Use the following procedures when installing a DDC monitor.

  1. Reset the display to the lowest refresh rate available.  This
     will prevent the system from attempting to display at a refresh
     rate higher than that supported by the new monitor.

  2. Shut down your system and install the new monitor.

  3. Restart your system.

  4. Select the "DDC Display Setup" icon in the OS/2 System Folder.

  5. When you are instructed to do so, shut down your system and
     restart it.


4.0  Preliminary Steps
______________________

The following steps must be performed before you install the
ViRGE,ViRGE/VX,ViRGE/DX,ViRGE/GX,ViRGE/GX2,Trio3D/2X graphics-accelerator device driver:

1.  You must have OS/2 DOS Support installed.
2.  If you previously installed SVGA support, you must reset the
    resolution to VGA mode, using the procedures in "Setting Your
    Display to VGA Mode" (section 5.0 in this README).
3.  The device driver diskette must be labeled "S3 DRV1."
4.  After driver installation, the OS/2 SYSLEVEL command may be used to
    confirm the new driver version level.  It may also be used prior to
    installation to verify the current driver version, however, some
    previous device drivers did not provide this information.  Following
    execution of the SYSLEVEL command look for the following information:

    C:\OS2\INSTALLATION\SYSLEVEL.VID
                                      ViRGE,ViRGE/VX,ViRGE/DX,ViRGE/GX,ViRGE/GX2,Trio3D/2X
    Version 2.81     Component ID 562107701
    Current CSD level: S328103
    Prior   CSD level: S328018

    In this case the current version level is S3 2.81.03.
5.  In some situations, installing this driver over 2.80.xx and 2.81.xx
    versions of the driver can result in duplicated icons.  To prevent
    this problem, you should delete the "S3 Windows Font Size" and
    "DDC Display Setup" icons from the System Setup Folder prior to
    installing this driver.

NOTES:

 o During the installation of this driver, DISPLAY.LOG and
   DSPINSTL.LOG files are created in the OS/2\INSTALL directory.
   These files identify the OS/2 system files that were updated and
   indicate whether the installation was successful.  The contents
   of these files might be useful if you need to report an
   installation problem to IBM.

 o If the video memory size is changed after the device driver is
   installed, the device driver must be reinstalled in order for
   the system to recognize the change.  Not reinstalling the driver
   might result in serious system problems.

 o When starting a WIN-OS/2 session it is recommended that the user launch
   the session via one of the WIN-OS/2 icons located in the "Command
   Prompts" folder within the "OS/2 System" icon.  For additional information
   see section 10.0 Limitations.


7.0  Installing in a CID Environment
______________________________________

NOTES:

 o The server must contain a directory named S3_DRVS on the same
   drive where the OS/2 diskettes reside.  The S3_DRVS directory
   must contain all of the files from the ViRGE,ViRGE/VX,ViRGE/DX,ViRGE/GX,ViRGE/GX2,Trio3D/2X device driver
   diskette.
 o OS/2 must have been successfully installed on the client using

  C:\OS2\INSTALL\DSPINSTL /pd:c:\os2\install\00S3.dsc
  /S:X:\img\s3_drvs /T:C: /res:640x480x256 /u

     /pd:c:\os2\install\00S3.dsc
      is the dsc laid down during setup phase.

     /S:X:\img\s3_drvs
      where X:\img\s3_drvs is the redirected source path.

     /T:C:
      where C: is the drive where OS/2 is installed.

     /res:640x480x256
      is a resolution/color depth from the list of "Supported
      Resolutions" that appears earlier in this README.

     /u
      means Unattended installation.

NOTES:

 o  Be sure you have the stated video memory required, as listed
    in "Supported Resolutions" earlier in this README.  A safe
    choice is 640x480x256.  Any of the listed resolutions can be
    selected, but your display might be damaged if you select a
    resolution that your display does not support.

 o  After the ViRGE,ViRGE/VX,ViRGE/DX,ViRGE/GX,ViRGE/GX2,Trio3D/2X device driver has been successfully
    installed on the client machine using the CID method and the
    client machine is restarted, the resolution will be as specified
    by command line argument.

 o  After the CID installation, refer the end user to section 6.0
    "Installation from Diskette," step 12.

8.0  Selecting Small or Large Fonts for Windows
_______________________________________

The default font sizes for Windows sessions are listed below.

  Resolution      Default Font Size
  ----------      ---------------------------
  640x480             Small
  800x600             Small
  1024x768            Large
  1280x1024           Large
  1600x1200           Large

  NOTE: Large fonts are not available for 640x480 resolution.

Use the following procedures to select small or large fonts
for Windows sessions.

  1. Select the "S3 Windows Font Size" object in the OS/2 System
     Setup Folder.

  2. Click on the radio button next to the font size you wish to
     select.

  3. Click on the OK button.

  4. A message will display saying that the new settings will take
     effect the next time you restart your Windows session.
     Currently open sessions will not be affected by the new
     settings.

  5. Click on the OK button.

  6. Start any WIN-OS/2 window or full-screen session.

The setting you select will remain in effect until you explicitly
change it, you change your display resolution, or you install a new
display driver.

9.0  Features and Fixes Included in this Driver
_____________________________________________

- "System - Settings" notebook support for setting refresh rate
- DDC monitor detection support
- Windows "Large font" and "Small font" support in high resolutions
- WIN-OS/2 based on latest S3 Windows 3.1 drivers
- One-diskette package

10.0 Limitations
_______________________

1. CID install pauses due to SVGA.EXE loading in the background.
   Workaround: In the CID install script, do not initiate any other
   processes until DISPINSTL completes execution.  Ensure that no
   other processes are running during CID install.  This can be
   accomplished by adding the following line to the CONFIGSYSLINE
   keyword of the CID response file:

   SET RESTARTOBJECTS=STARTUPFOLDERSONLY

2. During CID install of IBM AntiVirus when using NetView DM/2,
   the OS/2 full screen is displayed as a black screen.
   Workaround: Perform CID install under VGA.

3. DISPINSTL does not allow CID selection of monitor and refresh
   rate.  The workaround is as follows:

      Requirements:
      * A system with the same graphics card and monitor configured with the
        S3 driver version 2.81.05, the correct display type,
        the desired resolution, and the desired refresh rate.

      Step 1: Copy Configured Video/Display Data Files
      * copy the video and display data files containing information about
        the display type, resolution and refresh rate to the CID server
        (\img\svgadata).

        > copy \os2\svgadata.pmi x:\img\svgadata
        > copy \os2\video.cfg x:\img\svgadata

      Step 2: Create CID Command File
      * create a command file to copy svgadata.pmi and video.cfg to the
        client system's \os2 directory via CID.
      * reboot the client system.
      * the client system will be configured with the correct driver,
        display type, resolution and refresh rate.

4. In all modes, video corruption or out-of-sync screen is
   displayed when using  Alt+Esc to switch between WIN-OS/2,
   OS/2, and DOS window and full-screen sessions started from the
   Startup folder. To avoid this situation, do not start sessions
   from the Startup folder or press Alt+Esc several times to
   restore.

5. Some programs, such as WINBENCH95, WINBENCH96, and After
   Dark 3.0, were written specifically for the Windows environment.
   In the Windows environment, these programs prevent any keystrokes
   from interfering with their proper execution.  However, in the
   OS/2 environment, it is possible to switch context away from the
   Windows session without notifying these programs.  General
   Protection Faults (GPFs) may result.  Therefore, context
   switching during the execution of WINBENCH95 and WINBENCH96 tests
   is not recommended.  Also, context switching during the execution
   of the After Dark 3.0 demo is not recommended.

6. When attempting to start a WIN-OS/2 session from an OS/2 Full Screen
   session by typing "WIN" or "WINOS2" at the command prompt, it will not
   execute with the settings needed to support WIN-OS/2, and will result
   in video corruption and/or a system lockup.  It is recommended that the
   user launch all Windows sessions via one of the WIN-OS/2 icons located
   in the "Command Prompts" folder within the "OS/2 System" icon.

7. When attempting to start a WIN-OS/2 session from a DOS Full screen or
   DOS Window by typing the "WIN" or WINOS2" command, the user must first
   be sure that the video settings of the session are changed to enable
   this feature.  These settings can be changed using the following
   procedure:
    a) Place mouse pointer over the DOS Full Screen icon (or any DOS
       session icon you want to alter).  Press mouse button 2 (MB2), the
       right button, to bring up a context sensitive menu.
    b) Place mouse pointer over "Setting" and press MB1.  Next, place
       mouse pointer over the tab labeled "Session" and press MB1 again.
    c) Use MB1 to chose the "DOS Setting" button.
    d) Use MB1 to chose the "DOS video settings" option, and then click OK.
    e) From the list of settings which appear ensure that
       "VIDEO_8514A_XGA_IOTRAP" is switched OFF, AND
       "VIDEO_SWITCH_NOTIFICATION" is switched to ON,
       then "save" these settings using MB1.
