1. Release Notes
----------------

This STB Windows Display Support release includes STB Vision.  STB
Vision is an integrated Windows display driver and utility package
designed to increase your productivity as you work within the Microsoft
Windows environment.  STB Vision does this by providing easy to use
display driver installation and configuration and a collection of
advanced features that enhance the capabilities of your Windows display
device.

This release includes a new feature: Multiple Desktops.  Multiple
Desktops are an alternative approach to the Virtual Desktop for
providing you with more "screen real-estate" on which to run your
applications.  Multiple Desktops make it easier for you to organize
your work by allowing different groups of applications to run on
different desktops, and making it quick and easy to switch between the
different desktops and the applications that reside on them.  Multiple
Desktops are like having more than one display, only one of which can
be seen at a time.  You can switch between desktops by using hotkeys
you assign or by using the Multiple Desktop Manager.  You can turn the
Multiple Desktop Manager on or off using a hotkey you assign, or
directly from the STB Vision Control Panel.  For details on the
operation of the Multiple Desktop feature see the online help available
from within the STB Vision Control Panel.

This release supports Microsoft Windows 3.1 or higher, Windows for
Workgroups 3.1 or higher, and Windows for Pen Computing 3.1 or higher.

This release requires DOS 3.30 or higher.

This release requires a 386 or higher CPU.

5. Installation and Configuration Using the STB Vision
   Installation Utility and the STB Vision Control Panel
--------------------------------------------------------

The STB Vision Installation Utility, SETUP.EXE, is used to install STB
Vision.  The Installation Utility is a Windows-based application with a
simple and easy to use dialog and message box interface.

To install STB Vision you must run SETUP.EXE by selecting 'Run' from
the Program Manager or File Manager 'File' menu, typing in the path to
SETUP.EXE in the 'Command line' edit field, and then selecting 'OK'.
When SETUP.EXE displays its initial dialog, select 'OK' to confirm that
it is going to install STB Vision into the correct Windows directory.
SETUP.EXE copies and expands the release files into the appropriate
locations within your Windows and Windows System directories,
displaying its progress as it proceeds.  SETUP.EXE notifies you when
the file installation phase has been completed, it asks if you wish to
create an 'STB Vision' Program Manager group, and finally it starts the
STB Vision Control Panel, where you select your initial display
setting.  When you select 'OK' from the Control Panel, Windows is
restarted and your selected display setting is active.

The STB Vision Control Panel, STBVISN.EXE, is used to configure STB
Vision.  The Control Panel is a Windows-based application with a simple
and easy to use dialog and menu interface.

The STB Vision Control Panel main dialog is where you select your
display setting.  A display setting consists of a particular
combination of Colors, Virtual Desktop Size, Resolution, and Font Size.
After you have selected a new setting, select 'OK' to activate it.  You
can optionally save settings by name and later recall them, making it
easy to switch between the different settings you use frequently.

You can select options for the Multiple Desktop Manager, Zoom Window,
Bird's Eye Window, and the Control Panel itself from the options
dialogs that are available from the Control Panel 'Options' menu.
These options include the hotkeys used for direct invocation.  You can
invoke the Multiple Desktop Manager, Zoom Window, and the Bird's Eye
Window from the Control Panel 'Features' menu.

Context-sensitive help information is available in both the STB Vision
Installation Utility and the STB Vision Control Panel by selecting
'Help'.  The README.STB file containing information specific to your
STB product can be viewed by selecting 'ReadMe'.


6. Installation and Configuration Using Microsoft Windows Setup
---------------------------------------------------------------

STB Vision supports driver-only installation and configuration with
Microsoft Windows Setup, either from the DOS prompt or from within
Windows.  The executable file for Windows Setup is named SETUP.EXE and
is located in the Windows directory.

The STB Vision release for a given product contains an appropriate
OEMSETUP.INF file that supplies the information needed by Windows Setup
to install the drivers.  You perform the installation with Windows
Setup in the usual manner, selecting 'Other display' for your display
selection and the drive or path where the STB Vision release resides.
If you perform a driver-only installation with Windows Setup then the
STB Vision Control Panel and advanced features are not available.  You
can subsequently run the STB Vision Installation Utility to install STB
Vision and enable its features, if you choose to do so.

STB Vision supports driver-only configuration with Microsoft Windows
Setup, either from the DOS prompt or from within Windows.  You perform
the configuration with Windows Setup in the usual manner, selecting the
particular display driver configuration you wish to run in.  If you
have previously installed STB Vision with the STB Vision Installation
Utility, then you can subsequently run the STB Vision Control Panel to
reenable the STB Vision advanced features.  If you have not previously
installed STB Vision with the STB Vision Installation Utility, then you
must do so in order to install STB Vision and enable its features.


7. How to Set Vertical Refresh Rates
------------------------------------

You can set the vertical refresh rate for each resolution you will
run in using the CLMODE.EXE utility.  This utility is installed into
your Windows directory by the STB Vision Installation Utility.  This
utility has both a graphical user interface and a command line user
interface.  To invoke the utility in graphical mode, run CLMODE.EXE
with no command line options.  To get help on the supported command
line options, run CLMODE.EXE with the '/?' option.


8. Updating Existing Display Drivers
------------------------------------

You can update your existing display drivers by installing this release
"over the top of" your previous release.  This will overwrite any
previously existing files that have the same name as files in this
release.  Previously existing files that do not have the same names as
files in this release will not be overwritten and will not be deleted.
You can manually delete these files if you choose to do so.

One issue that frequently occurs when updating existing display drivers
or installing drivers for a new display adapter is the issue of
obsolete OEMSETUP.INF files remaining in your Windows System directory.
These files are used by Windows Setup to produce the list of display
settings from which you may select.  If you have obsolete OEMSETUP.INF
files in your Windows System directory, Windows Setup may show the
display settings from those files in the list of display settings.  If
you select one of these obsolete display settings your Windows display
configuration will likely be invalid and you will not be able to run
Windows until the problem is corrected.  You can prevent this problem
from occuring by inspecting the display device OEM*.INF files in your
Windows System directory and deleting those that are obsolete.  You
must be careful to not delete INF files that are not obsolete or that
are not display device specific.  Should you delete one of these files
that is not obsolete or is not display device specific, you will
adversely affect your ability to change your Windows configuration.

Another issue that frequently occurs when updating existing display
drivers or installing drivers for a new display adapter is the issue of
having too many OEMSETUP.INF files remaining in your Windows System
directory.  When this occurs Windows Setup will produce an "out of
memory" error when you attempt to configure a new display setting when
running Windows Setup from DOS (i.e. outside of Windows).  The solution
to this problem is to delete any obsolete display device OEM*.INF
files.


9. Miscellaneous Product-Specific Utilities
-------------------------------------------

You can adjust image centering for each extended VGA mode you will run
in using the CLMODE.EXE and CENTER.COM utilities.  These utilities are
installed into your Windows directory by the STB Vision Installation
Utility.  CLMODE.EXE is used to interactively adjust image centering.
CENTER.COM is a TSR that enables your centering adjustments after you
have specified them with CLMODE.EXE.  CENTER.COM must not be loaded at
the time you make your adjustments with CLMODE.EXE.  After you have
made your adjustments with CLMODE.EXE you must load CENTER.COM for your
adjustments to take effect.  If you want your adjustments to take
effect every time you start your system you should load CENTER.COM in
your AUTOEXEC.BAT file.  Online help is available in the 'Video Modes'
section of CLMODE.EXE that further explains the steps required to
adjust image centering.

The TSRFONT.COM driver provides support for the 8x14 text font.  This
utility is installed into your Windows directory by the STB Vision
Installation Utility.  If you run applications that require this font
you must load this driver before running those applications.  If you
frequently run applications requiring this font you should load this
driver in your AUTOEXEC.BAT file.  Very few applications require the
8x14 font.

The Display Power Manager screen saver, PMSAVER.SCR, can be used to
control the power consumption of your monitor.  It provides five levels
of power savings control.  PMSAVER.SCR is installed into your Windows
directory by the STB Vision Installation Utility.  You can enable and
configure PMSAVER.SCR from the 'Desktop' control of the Windows Control
Panel.  Online help is available to further explain how to use this
utility.


10. Miscellaneous Product-Specific Issues
-----------------------------------------

The 1280x1024 256 color mode at 60 Hz is not available on your product
because the hardware cursor does not function correctly in this mode.
If you run CLMODE.EXE and specify 60 Hz as your 1280x1024 vertical
refresh rate, the refresh rate will be reset back to 87i automatically
by the STB Vision software.  If you last installed or configured your
Windows drivers with Windows Setup, the refresh rate will not be
automatically reset, and you will see a "split" cursor when running in
this mode.  In this case you should run CLMODE.EXE and select 87i
for your 1280x1024 refresh rate.


11. Recovering from an Invalid Windows Display Configuration
------------------------------------------------------------

The STB Vision Installation Utility and the STB Vision Control Panel
are Windows-based applications that run under Windows.  Thus you
could have difficulty reconfiguring or reinstalling STB Vision if the
current Windows display configuration is invalid.  When the Windows
display configuration is invalid, Windows is either unable to run or
you cannot see what it is displaying, and therefore you are unable to
run STB Vision SETUP.EXE and STBVISN.EXE under Windows.

There are many things that can cause an invalid display driver
configuration.  One of the most common causes is switching to a
monitor that does not support the currently configured resolution or
vertical refresh rate without first running the proper utility to
configure for the new monitor.

The key to recovering from an invalid Windows display configuration
is to temporarily reconfigure Windows to use the standard VGA display
driver.  First, run Windows Setup (SETUP.EXE in the Windows
directory) from the DOS command prompt and select 'VGA' for the
'Display' setting.  You can then run Windows and run the STB Vision
Control Panel, STBVISN.EXE, to reconfigure STB Vision, or run the STB
Vision Installation Utility, SETUP.EXE, to reinstall STB Vision.
Then specify a valid display setting and select to restart Windows.


12. The STB Vision Configuration File (STBVISN.INI)
---------------------------------------------------

The STB Vision configuration is stored in the STBVISN.INI file.  The
STB Vision Installation Utility installs STBVISN.INI into your
Windows directory.  When you use the STB Vision Control Panel to
change your STB Vision configuration (i.e. display setting and
feature options) the STBVISN.INI file is updated to reflect your
changes.

You should not manually edit or delete the STBVISN.INI file, as by
doing so you risk corrupting your STB Vision configuration.  Should
you accidentally corrupt your STB Vision configuration, you may be
able to correct it by running the STB Vision Control Panel and
selecting a new display setting.  If this does not correct the
problem you must reinstall STB Vision with the STB Vision
Installation Utility.


13. The STB Vision Display Meta Driver (STBVISN.DRV)
----------------------------------------------------

Much of the support for the STB Vision advanced features and hotkeys
is implemented in STBVISN.DRV.  When you install STB Vision with the
STB Vision Installation Utility, STBVISN.DRV is installed into your
Windows System directory and your Windows SYSTEM.INI file is modified
to make STBVISN.DRV the active display driver.

You should not manually edit the display driver configuration in the
SYSTEM.INI file, as this could corrupt your STB Vision configuration.
Should you accidentally corrupt your STB Vision configuration, you may
be able to correct it by running the STB Vision Control Panel and
selecting a new display setting.  If this does not correct the problem
you must reinstall STB Vision with the STB Vision Installation Utility.


14. How to Obtain Customer Support
----------------------------------

Follow one of the steps below in order to obtain customer support in
helping to resolve any problems you may have in installing or configuring
your STB product:

        1. If you obtained your STB product as part of a system purchase,
           contact your system manufacturer for technical support.

        2. If you purchased your STB product directly or through a
           retailer, contact STB by using the information provided
           in your user's guide.

You can help the support technician solve your problem by providing the
following information:

        Which STB product you are using
        STB Vision Windows Display Support version
        Detailed description of the problem
        Steps required to duplicate the problem
        Microsoft Diagnostics report (run the MSD.EXE utility)
        Contents of the STBVISN.INI file
        System manufacturer and model
        Monitor manufacturer and model

The MSD.EXE Microsoft Diagnostics utility is included with all versions
of Windows 3.1 and higher.  It is located in your Windows directory.

The easiest way to determine the STB Windows Display Support version is
to run STB Vision SETUP.EXE or STBVISN.EXE from a DOS command prompt.
When run from the DOS command prompt both of these programs will
display their identification information, including their version
number and build date.  SETUP.EXE also displays its identification
information on the initial dialog it displays.  STBVISN.EXE also
displays its identification information on its About box.  To display
the About box, select 'About' from the 'Help' menu.
