                  Hercules Stingray PCI(tm)    (S801)

                  Supplemental Drivers Diskette 1 for
                    IBM OS/2 2.1 / OS/2 for Windows

                  (Windows NT display drivers are on
                   Supplemental Drivers Diskette 2)



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

        The OS/2 installation procedure is as follows.  Steps 1 - 9 are
        required only for first time installation of the Stingray
        drivers.

        1)      Under the OS/2 desktop, select the "OS/2 System" icon
                and then select the "Command Prompts" folder.

        2)      Select either the OS/2 Window or OS/2 Full Screen icon.

        3)      From the OS/2 command prompt, type DSPINSTL.  (For best
                results, close all seamless Windows and full screen
                applications before running DSPINSTL.)

        4)      Select "SuperVGA (SVGA)" from the list of available
                drivers and follow any prompts that DSPINSTL gives you.
                When DSPINSTL is completed, you will be returned to the
                command prompt.

        5)      Shut down OS/2 and reboot your system.

        6)      After OS/2 has rebooted, under the OS/2 desktop again
                select the "OS/2 System" icon and then select the
                "Command Prompts" folder.

        7)      Select an OS/2 Window (either Desktop or Full
                Screen).

        8)      Insert Supplemental Drivers Diskette 1 into the floppy
                drive (e.g. A:)

        9)      If the floppy drive is A: and OS/2 is installed on C:,
                type:

                A:      [to log onto the A: drive]

                install.cmd a c

                (Substitute different drive letters on the command line
                if necessary.  For help, just type "install.cmd" with no
                parameters.)

                This installs the driver files on the hard drive.


        10)     From the OS/2 command prompt, type DSPINSTL again.  (For
                best results, close all seamless Windows and full screen
                applications before running DSPINSTL.)

        11)     Select "Primary Display" and click on OK.

        12)     Select "Advance Logic, Inc." from the driver selection
                menu.

        13)     Select "Install Using Defaults for Monitor Type" from
                the "Monitor Configuration/Selection Utility" menu.

        14)     You will be prompted for the Video Refresh Rate
                Selection Menu.

                IMPORTANT: If you are not sure of your monitor's maximum
                refresh rate, say "NO."  Selecting a refresh rate not
                supported by your monitor could lock up the system
                (possibly requiring a reinstall of OS/2), damage your
                monitor, or both.

                If you select "YES," the AScanOS2 utility is invoked.
                AScanOS2 presents the scan rates available with
                Stingray.  Consult your monitor documentation and select
                the scan rates accordingly.  If you are not sure which
                scan rates to choose, select the lowest scan rates in
                each of the four columns.

        15)     Select your desired display resolution from the list of
                available resolutions.

        16)     You will be prompted for Supplemental Display Driver
                Diskettes 1 and 2.

        17)     When DSPINSTL is completed, shut down OS/2 and reboot
                your system.

        NOTE: Your Stingray Supplemental Display Driver Diskettes are
        shipped with volume labels DISP 1 and DISP 2.  If you make a
        backup copy of your diskettes, use the DOS LABEL command to
        label the copies accordingly.  If the Supplemental Display
        Driver Diskettes do not have the correct volume labels,
        installation will fail.


        Changing Resolutions
        --------------------

        To change the display resolution or pixel depth (number of
        colors) at any time, follow steps 10 - 17.


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

        The following limitations have been observed:

        - At the 1024x768x256 resolution, if you open "Colors" in the
          Control Panel under a Windows session, the Custom Color
          Selector may be displayed incorrectly.  Use the right mouse
          button to invoke the refresh command.  This will clear the
          screen.

        - A General Protection Fault (GPF) may occur when running the
          WinTach benchmark program under a seamless Windows session.

        - When running WinBench 3.11 under a seamless Windows session
          and choosing the "Advanced Tests" option, portions of dialog
          boxes and pull-down menus may be blank.  This error does not
          occur in full screen Windows sessions.

        All of these symptoms have been observed on other video cards as
        well, and IBM has been notified.
