Using the Utilities:
--------------------


SMODE
-----
Smode.exe is a utility which allows the user to set emulation and display modes.

Usage:

SMODE   [Display Mode] [Emulation Mode] [Noclear] [P#]

[Display Mode]          This option can be any valid BIOS display mode.

[Emulation Mode]        This option is used to select the Emulation mode.
                        Valid emulation modes are:

                        VGA             Normal operation;
                        CGA             CGA operation;
                        MDA/HERC        Monochrome Enulation.

[Noclear]               If this option is specified, the video memory will be
                        preserved (not clear) across a mode set.

[P#]                    This option is used to set the active display page.


S3REFRSH
--------
This utility requires that a mouse driver be installed. Without a mouse driver,
command line parameters are required using the following options:

   Usage(without mouse):

        S3REFRSH X Y

        where X = 640, 800, 1024, 1280

        and Y = 0(56Hz), 1(60Hz), 2(70Hz), 3(72Hz), 4(75Hz), 5(Interlaced)

        Note that 1600x1200 and 1152x864 each have a single refresh rate so this
        utility is not needed.

With a mouse driver, a menu will be displayed upon loading S3REFRSH. The refresh
rate options are shown on the left side and the corresponding resolutions are
displayed on top of the table. Click on the disired boxes. The "X" marks mean
that the selection is not valid; selected refresh rates are defined by the check
marks. Click on the EXIT button to set the new refresh rate. The utility will
ask if the user wishes to save the changes in AUTOEXEC.BAT. Choose YES if the
user wants to use the new refresh rate values every time the system boots.

---------------------------------------------------------------------------
Note: The path of changes in AUTOEXEC.BAT done by S3REFRSH may be not correct.
You can set the correct path or copy the S3REFRSH program to root directory in
hard drive C: manually.
---------------------------------------------------------------------------


FCON
----
FCON.EXE is a utility that allows the user to easily enable feature connector
for test purposes. This utility is only required for 2- and 4-MByte
configurations as the BIOS automatically enables feature connector operation for
1-MByte configurations.

   Usage:        ÚÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ¿
