INSTALLATION NOTES:
-------------------

 1.  You must have OS/2 DOS Support installed in order to install this driver.

 2.  The OS/2 ATTRIB command is used during installation.  If you elected not
     to install the OS/2 System Utility Programs or you have deleted the
     ATTRIB, command you must use Selective Install to restore the ATTRIB
     command before continuing.

 3.  If you previously installed SVGA support, return to VGA resolution using
     the new SETVGA procedure found at the end of this README before you
     install this driver.

 4.  You must have run the S64MODE.EXE utility and selected a monitor
     from the Stealth 64 Installation disk prior to installing these
     drivers.  **You must select a predefined monitor, as Custom does not 
     work properly under OS/2.  If you have not done this, do so now.  Note, 
     that the S64MODE.EXE which is on this disk, does not list Custom monitor 
     as an option.  Refer to instructions in the Stealth 64 User's Manual for 
     running S64MODE.EXE and selecting a monitor.

5.   The Volume Labels for the diskettes must be 'S3 DRV1' and 'S3 DRV2' for
     the first and second diskettes respectively.

INSTALLATION:
-------------

This video accelerator driver is compatible with OS/2 2.1.  Do not install it
over any display driver other than VGA.

 1.  Place the Stealth 64 VRAM OS/2 driver diskette into drive A (or any other 
     diskette drive).

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

 3.  Change to the OS/2 directory.  Then type 'attrib -r -s -h screen0*.sys'.

 4.  Then switch to the floppy drive where you inserted the Stealth 64 OS/2 
     driver disk.  Then, at the prompt, type the following command:

     S3INST A: C:

          where:  A: is the diskette drive
                  C: is the drive where OS/2 2.1 is installed

     This command will copy all necessary files to the OS/2 drive.  You will 
     be requested to put disk #2 into the drive.

 5.  When S3INST has completed executing, remove the diskette from the 
     diskette drive, perform a shutdown, and then restart the system.

 6.  Open the "OS/2 System" folder.

 7.  Open the "System Setup" folder.

 8.  Open the "Display Driver Install" (DSPINSTL) object.

     When the Display Driver Install window appears, chose primary display,
     then select "OK".

     The Primary Display Adapter type window will then appear with 
     a list of drivers.  You will want to select the '32-bit S3 Display 
     Drivers v2.4', this should be toward the beginning of the list.  Then 
     click "OK".

     When the Monitor Configuration/Selection Utility window appears,
     the "Install Using Defaults for Monitor Type" option is preselected.
     Select the "Install Using Display Adapter Utility Program" option, then
     select "OK".

  9. The Monitor Configuration/Selection Utility Location windows should
     appear.  For the Utility Location, type:

             C:\S64\UTIL\S64MODE.EXE MONITOR

     If you installed S64MODE into a different directory, modify the above
     path accordingly.  Select "OK".

  10. When the source directory pop-up window appears, insert the Stealth 64
     OS/2 Driver diskette 1 of 2, and select Install.

     DSPINSTL determines the hardware configuration by creating the
     SVGADATA.PMI file on the drive where the OS2 directory is located.
     If the SVGADATA.PMI file has not been created, the adapter will not be
     supported.

 11.  When the installation is complete, do the following:
       a.  Open "OS/2 System".
       b.  Open "System Setup".
       c.  Open the "System" object.  The Screen page of the Settings
           notebook lists all the supported resolutions for your
           configuration.
       d.  Select a resolution; then, close the notebook.

 12.  Perform a shutdown; then, restart the system.

Note that during the installation of this driver a DISPLAY.LOG file is
created in the OS2\INSTALL directory.  This file identifies the OS/2 2.1
system files that were updated and indicates whether the installation was
successful.  The contents of this file might be useful if you need to report
an installation problem to Diamond Multimedia Systems.

Known Limitations
-----------------

  S64MODE monitor selections
  --------------------------
  The Custom monitor selection does not work properly with OS/2.  You will
  need to select one of the predefined monitors.

  DOS Sessions and Applications
  -----------------------------
  With the program VPIC6 under FS DOS, GIFs cannot be viewed in the 1280x1024
  resolution.

  OS/2 Full Screen Sessions and Applications
  ------------------------------------------
  Context switching from Win-OS/2 full screen to OS/2 full screen may
  produce a distorted text in OS/2 full screen.

  MMPM/2
  ------
  When using 16.7Million colors, Digital Video will display black on the 
  screen. This is a limitation of MMPM/2, and 32-bpp modes.
