  2.0  Compatibility
  __________________

  This graphics accelerator device driver is compatible with OS/2
  2.11, OS/2 Warp 3.0, and OS/2 Warp 4.0.  The installation procedures
  for the three supported versions of OS/2 will vary. Please read
  this entire document to determine the required steps for your
  environment.


  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 adjusts the 
  available selections to match the monitors capabilities. If the 
  monitor attached to the system is included on the list, which
  appears on page 2 of the System Properties Screen Tab, that monitor
  should be used, not the DDC or Default.

  When switching to a different monitor, you must run the DDC Display
  Setup program in the System Setup Folder.

  Use the following procedure after attaching a different DDC monitor
  to your system.

    1. In the System Setup Folder, 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
  display 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. Use "Label A:" to verify that the device driver diskette is 
     labeled "S3 DRV1."

  4. The OS/2 SYSLEVEL command may be used prior to installation 
     to verify the current driver version. NOTE: some previous device 
     drivers did not provide this information.  
     Execute the SYSLEVEL command and look for the information
     similar to the following:

     C:\OS2\INSTALLATION\SYSLEVEL.VID
				      ViRGE,ViRGE/VX,ViRGE/DX,ViRGE/GX
     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.
 

  5.0  VGA Mode Reset
  ___________________

  Use the following procedures to reset to VGA mode.

  NOTE: If your display is out of sync, start OS/2 using the OS/2
	Installation Diskette.	Insert Diskette 1 when prompted, 
        press F3 to display a command prompt, and then use the 
        following instructions to reset your display mode.

  o OS/2 Warp 3.0 or OS/2 Warp 4.0 VGA mode reset:

      1. Restart your computer.

      2. Simultaneously press Alt and F1 key immediately when a 
         square block appears in the top left hand corner.

      3. In OS/2 Warp 3.0, press 'v' key for VGA.
         In OS/2 Warp 4.0, press F3 key for VGA.
    
      4. Perform a shutdown and restart your computer. 

      5. Proceed to Section 6.0 or 7.0.

	   [OS2 DRIVE]:\OS2\INSTALL\00S3.DSC

      2. Be sure RSPDSPI.EXE is in the \OS2\INSTALL directory.  
         If it is, go to step 3.  
         
         If installing from diskette, insert OS/2 Diskette 8 into
           drive A and unpack RSPDSPI.EXE with the following command:

           C:\OS2\UNPACK A:\INSTAID C: /N:RSPDSPI.EXE

           where A: is the drive containing Diskette 8, and C: is the
           drive where OS/2 is installed.

         If installing from CD or LAN, unpack RSPDSPI.EXE with the
           following command:

	   C:\OS2\UNPACK E:\DISK_8\INSTAID C: /N:RSPDSPI.EXE

           where C: is the drive where OS/2 is installed, and E: is
           the CD-ROM or LAN drive.

      3. Type C: and then press Enter.

      4. Type CD C:\OS2\INSTALL and then press Enter.

      5. If installing from diskette, type the following:

           RSPDSPI /PK:VGA /SK:NONE /S:A:\ /T:C:
	
           In /S:A:, A: is the source diskette drive for installing 
           the device driver.
           In /T:C:, C: is the target drive where OS/2 is installed.  

	 If installing from CD or LAN, type the following:

	   RSPDSPI /PK:VGA /SK:NONE /S:E:\OS2SE21\ /T:C:
  
           In /S:E:, E: is the source CD-ROM or LAN drive.
	   In /T:C:, C: is the target drive where OS/2 is installed.  

	 Then press Enter.

      6. Perform a shutdown and restart your computer.

      7. Proceed to Section 6.0 or 7.0.


  6.0  Installing the S3 Display Driver from Diskette
  ___________________________________________________

  To install the display driver from diskette, do the following:

  1. If your system is not in VGA mode, set the display to VGA mode. 
     See steps above.

  2. Insert the S3 ViRGE display driver diskette, with the label
     "S3 DRV1", into drive A (or any other diskette drive).

  3. Open an OS/2 full-screen or OS/2 window session.

  4. At the OS/2 command prompt, type the following command to copy
     all necessary files to the OS/2 drive:

       A:SETUP

       where A: is the diskette drive.

     Then press Enter.

     Setup will then identify your chipset.  When prompted to do so, 
     press Enter to continue.

  5. When the Monitor Configuration/Selection Utility window appears,
     the "Install Using Defaults for Monitor Type" choice is
     pre-selected.  Select OK. 
     Do NOT select "Install Using Display Adapter Utility Program" 
     since this method of setting refresh rates is not supported 
     in this driver version.

     NOTE:  DSPINSTL determines the hardware configuration by
	    creating the \OS2\SVGADATA.PMI file.  If the
	    \OS2\SVGADATA.PMI file has not been created, the adapter
	    will not be supported.  This process can take several
	    seconds and will black-out the screen.

  6. When the installation is complete, shut down your system, remove
     the diskette, and restart your computer.

  7. When the system has restarted:
      a. Open the OS/2 System Folder.
      b. Open the System Setup Folder.
      c. Open the System object.
      d. When the Settings notebook (for OS/2 3.0) or 
         System Properties (for OS/2 4.0) appears, 
         select the Screen tab.
     
     If your monitor has been detected as Plug and-Play (DDC)
     compatible, go to step 9.

  8. If your monitor has not been detected as DDC compatible,
     on page 2 of Screen Tab, select your display from the display list.
     If your display does not appear in the list, select Default.

     Restart your computer to ensure all refresh rate options are
     available.

  9. When the system has restarted:
      a. Open the System object and select page 1 of Screen Tab,
         as in step 7.
      b. Select the desired screen resolution and a screen refresh rate.
      c. Close the Settings notebook or System Properties.
      d. Perform a shutdown and restart your computer.

  NOTES:

   o If the selected vertical refresh rate is not supported by your
     monitor, delete \OS2\VIDEO.CFG file and reboot. This will set
     the refresh rate to the default value. A new refresh rate can
     then be selected using the procedure described above.

   o During the installation of this driver, DISPLAY.LOG and
     DSPINSTL.LOG files are created in the OS2\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 The display driver should be re-installed with any changes in
     video hardware configuration.  Not re-installing 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 9.0 Known 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 display device driver
     diskette.
   
   o OS/2 must have been successfully installed on the client using
     the CID (Configuration Installation Distribution) method.

  To install the S3 display device driver using CID, use the following
  information to modify your LCU command file.

  NOTE:  The following information is meant as a guide.
	 Your LCU command file might be different.

    /*****************************************************/

  Following is an explanation of the line that is executed in the 
  LCU command file:

    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 supported resolution and color depth combination.
	
       /u
	means Unattended installation.

  NOTES:

   o  To select a refresh rate, SVGA.EXE can be executed again 
      separately after DSPINSTL. Example, SVGA ON INIT 1024 75
      This will create another \OS2\VIDEO.CFG file with 75Hz as 
      the default at 1024x768 resolution. The prior \OS2\VIDEO.CFG 
      file should be deleted first.

   o  After the S3 display device driver has been successfully
      installed on the client machine using the CID method and the
      client machine is restarted, the resolution will be that 
      specified by command line argument.

   o  After the CID installation, refer the end user to section 6.0
      "Installing the S3 Display Driver from Diskette," step 7.


  8.0  Selecting Small or Large Fonts for Windows
  _______________________________________________

  The default font sizes for Windows sessions are listed below.

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

  Use the following procedure to change fonts for Windows sessions.

    1. Open the OS/2 System Setup Folder and select the "S3 Windows 
       Font Size" object.

    2. Select the radio button next to the desired font size.

    3. Select OK.

    4. A dialog box appears with the message that the new settings 
       will take effect the next time you restart your Windows session.
       Current open sessions will not be affected by the new
       settings.

    5. Click OK.

    6. Start any WIN-OS/2 window or full-screen session.
    
  Selected settings remain in effect until explicitly changed, or the
  display resolution or driver is changed.

 
  9.0 Known 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 installation 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:

     a) Create a master cfg file using a system with the same graphics 
        card and monitor configured with the S3 driver, the correct 
        display type, and the desired resolution and refresh rate.

     b) 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

     c) Create a CID Command file to copy svgadata.pmi and video.cfg 
        to the client system's \os2 directory via CID.
	 
     d) Execute the CID file.

     e) Reboot the client system. The client system will be configured
        with the correct driver, display type, resolution and refresh 
        rate.

  4. In OS/2 3.0, when attempting to start a WIN-OS/2 session from a 
     DOS Full screen or DOS Window using the "WIN" command, be sure
     that the video settings of the session are set to enable this
     feature:  
     a) Click, using the Number 1 mouse button, on the DOS Full Screen
        icon (or any DOS session icon you want to alter). A context 
        sensitive menu will appear.
     b) Select Settings. The DOS Full Screen (or Window) Settings Notebook
        will appear.
     c) Select the Session tab.  The DOS Full Screen or DOS Window
        Radio Button should already be selected.  If not, select the 
        desired radio button.
     d) Select the DOS Settings push button.

  5. In OS/2 4.0, when attempting to start a WIN-OS/2 session from a
     DOS Full screen or DOS Window using the "WIN" command, be sure
     that the video settings of the session are set to enable this
     feature:
     a) Click, using the Number 2 mouse button, on the DOS Full Screen
        icon (or any DOS session icon you want to alter). A context 
        sensitive menu will appear.
     b) Select Properties.  The DOS Full Screen (or Window) Properties
        Notebook will appear.
     c) Select the Session tab.  The DOS Full Screen or DOS Window
        Radio Button should already be selected.  If not, select the 
        desired radio button.
     d) Select the DOS Properties push button.
     e) Select the DOS Video Settings radio button.
     f) Select the OK push button.  The DOS Settings - DOS Video Settings
        window will appear.
     g) From the list of settings which appear ensure that
	"VIDEO_8514A_XGA_IOTRAP" is switched OFF, AND
	"VIDEO_SWITCH_NOTIFICATION" is switched to ON.  
     h) Select the Save push button.
     i) Close the DOS Full Screen (or Window) Settings Notebook.

 NOTES:

   o Any session started with this altered icon will support a Windows
     session started with the WIN command.
   
   o Some DOS games will not run properly with these altered settings.
     Therefore, it is recommended that you reset the altered settings
     to their defaults first.

   o If a WIN-OS2 session is started without changing the 
     "VIDEO_8514A_XGA_IOTRAP" or "VIDEO_SWITCH_NOTIFICATION" options,
     and the WIN-OS2 session hangs, use the following recovery
     procedure rather than powering off your system:
     a) Press Ctrl+Esc.  This displays the OS/2 Window List.
     b) Click, using the Number 2 mouse button, on the DOS session
        which has the WIN-OS2 session running. A context sensitive
        menu is displayed.
     c) Click, using the Number 1 mouse button, on the Close option.
        A DOS Window (or Full Screen) message is displayed stating 
        that this session may have an active program and asking if it
        should be closed without saving your data.
     d) Click on the YES push button.  The WIN-OS2 Session and the DOS
        Window (or Full Screen) will be closed.
