3. Supported Features
---------------------

This release of STB Vision 95 supports these features:
        
    Control Panel
    Icon Toolbar
    Virtual Desktop
    Dynamic Desktop Area and Resolution Switching (Zoom In/Out)
    Multiple Desktops
    Zoom Window
    Bird's Eye Window
    Monitor Options (with Dynamic Refresh and Centering Control)
    Status Display

Control Panel

The STB Vision 95 Control Panel is where you change your display
setting and start and configure the other STB Vision 95 features.  A
display setting consists of a particular Color Palette, Desktop Area,
Resolution, and Font Size combination.  Save and recall your favorite
display settings by names using the Saved Settings controls.

Start the Control Panel by clicking button 1 on its icon on the
system's taskbar, or by typing its hotkey.  The default hotkey is
Ctrl+Alt+C.

Change hotkey and other options with the Control Panel Options
dialog, which is accessible from the Control Panel window's system
menu (i.e. the icon in the very upper left corner of the window).

Icon Toolbar

The STB Vision 95 Icon Toolbar provides an alternative configurable
interface for selecting your display setting and starting the other
STB Vision 95 features.

Switch to the Icon Toolbar interface by clicking button 1 on its icon
on the Control Panel.  The Icon Toolbar uses the same hotkey as the
Control Panel (Ctrl+Alt+C).

Change the position of icons on the Icon Toolbar by dragging and
dropping them right on the toolbar.  Add and remove icons with the
Icon Toolbar Options dialog, which is accessible from the system menu
of the Icon Toolbar and Control Panel windows, and by clicking button
2 on the Icon Toolbar icon on the Control Panel.

Virtual Desktop

The Virtual Desktop allows Windows 95's Desktop Area to be larger
than the resolution actually displayed on your monitor.  Select the
Desktop Area and Resolution from the STB Vision 95 Control Panel's
Display Setting group.  Pan around the desktop by dragging the mouse
cursor past an edge of the screen, or by using the Bird's Eye Window.
In concert with Dynamic Resolution Switching, the virtual desktop
allows you to "zoom in" or "zoom out" to see more detail or get more
of an overview of your document or desktop.

If you own the "ultimate" professional monitor, capable of displaying
high resolutions at high refresh rates, then the virtual desktop may
not be for you.  However, if you own a low to moderate capability
"consumer" monitor, then the virtual desktop allows you to run
Windows 95 with a larger Desktop Area and at higher refresh rates
than otherwise possible by displaying a Resolution on your monitor
that is less than the Desktop Area.

Dynamic Desktop Area and Resolution Switching (Zoom In/Out)

You can change Windows 95's Desktop Area and the Resolution displayed
on your monitor without restarting Windows 95.  Select the new
Desktop Area and/or Resolution on the STB Vision 95 Control Panel and
then select 'OK' or 'Apply' to perform the switch.  You can also
switch from the Icon Toolbar.  The Icon Toolbar comes pre-configured
with icons for switching to all resolutions supported by your
product.  You can use the Icon Toolbar Options dialog to add the
icons for switching to your favorite Desktop Area selections.

In concert with the Virtual Desktop, Dynamic Resolution Switching,
allows you to "zoom in" or "zoom out" to see more detail or get more
of an overview of your document or desktop.  To "zoom in", switch to
a lower resolution.  To "zoom out", switch to a higher resolution.

Multiple Desktop 

The Multiple Desktop is an alternative approach to the Virtual
Desktop for providing 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 are running on them.
Multiple Desktops are like having more than one display, only one of
which can be seen at a time.

Switch between desktops by using hotkeys you assign or by using the
Multiple Desktop Manager.  Start the Multiple Desktop Manager by
clicking button 1 on its icon on the Control Panel, or by typing its
hotkey.  The default hotkey is Ctrl+Alt+D.

Change hotkey and other options with the Multiple Desktop Options
dialog, which is accessible from the system menu of the Control Panel
window, and by clicking button 2 on the Multiple Desktop icon on the
Control Panel.

Zoom Window

The Zoom Window shows a magnified view of a selected area of the
display.  This makes it easy to see fine details, even individual
pixels, of the document or image you are working on.  This is useful
when performing functions such as image editing.

Start the Zoom Window by clicking button 1 on its icon on the Control
Panel, or by typing its hotkey.  The default hotkey is Ctrl+Alt+Z.

Change hotkey and other options with the Zoom Options dialog, which
is accessible from the system menu of the Control Panel window, and
by clicking button 2 on the Zoom Window icon on the Control Panel.

Bird's Eye Window

The Bird's Eye Window shows a reduced view of your entire Virtual
Desktop.  Click button 1 within the Bird's Eye Window to pan to a
selected area of the Virtual Desktop.  You can also use the Bird's
Eye Window to get a quick overview of where your windows are located
on your Virtual Desktop.

Start the Bird's Eye Window by clicking button 1 on its icon on the
Control Panel, or by typing its hotkey.  The default hotkey is
Ctrl+Alt+B.

Change hotkey and other options with the Bird's Eye Options dialog,
which is accessible from the system menu of the Control Panel window,
and by clicking button 2 on the Bird's Eye Window icon on the Control
Panel.

Monitor Options (with Dynamic Refresh and Centering Control)

The Monitor Options dialog is where you control vertical refresh
rates and adjust image centering.  Your changes are "live", they take
effect immediately without having to restart Windows 95.  You can
also control how dialog and message boxes are centered on the virtual
desktop, choosing to center them on the monitor, the virtual desktop,
or to use the Windows 95 default centering approach.

Start the Monitor Options dialog by clicking button 1 or 2 on its
icon on the Control Panel or Icon Toolbar.

See section 6 of this file for instructions on how to select a
monitor.

Status Display

The Status Display displays detailed configuration information that
is useful in diagnosing any problems you may experience.  You can
print the information or copy it to the clipboard.

Start the Status Display from the Control Panel window's system menu
(i.e. the icon in the very upper left corner of the window).


4. Integration with Display Properties / Settings
-------------------------------------------------

The standard location for controlling your display configuration in
Windows 95 is the Display Properties / Settings dialog.

Start the Display Properties / Settings dialog by clicking button 2
anywhere on the Windows 95 desktop, selecting Properties from the
popup menu, then selecting the Settings tab.  You can also start the
Display Properties / Settings dialog by selecting Display on the
Windows 95 Control Panel.  Start the Windows 95 Control Panel from
the My Computer folder on the Window 95 desktop.

STB Vision 95 is designed to cooperate fully with the Display
Properties / Settings dialog.  Changes made to the Display Setting
with STB Vision 95 are reflected on the Display Properties / Settings
dialog.  Changes made to the Display Setting with the Display
Properties / Settings dialog are reflected in STB Vision 95.  Also,
STB Vision 95 uses the capabilities of the monitor selected from the
Display Properties / Settings dialog to allow only display
configurations that are supported by that monitor to be selected.


5. Installation and Configuration
---------------------------------

The Windows 95 Display Properties / Settings dialog is used to
install STB Vision 95.  See section 4 of this file for instructions
on how to start the Display Properties / Settings dialog.

When changing display adapters it is recommended that you first
configure your system to use the standard VGA or super VGA display
driver before removing your old display adapter board and installing
the new one.  Although this step is not necessarily required under
all circumstances, you are less likely to experience installation
problems if you follow it.

To configure your system to use the standard VGA or super VGA display
driver, select Change Display Type from the Display Properties /
Settings dialog.  Then select Change from the Adapter Type group of
the Change Display Type dialog, then select Show all devices from the
Select Device dialog, then select (Standard display types) under
Manufacturers and either VGA or Super VGA under Models, then select
OK from the Select Device dialog, then select Close from the Change
Display Type dialog, then select Yes to restart your computer.

To install STB Vision 95, select Change Display Type from the Display
Properties / Settings dialog.  Then select Change from the Adapter
Type group of the Change Display Type dialog, then select Have Disk
from the Select Device dialog, then enter the path to your STB Vision
95 release disk or directory.  At this point, you are presented with
the list of STB products supported by your STB Vision 95 release.
Select the line for your STB product that ends in "(with STB Vision
95)" to install the display drivers for your product and the STB
Vision 95 interface and features.  Select the line that ends in
"(without STB Vision 95)" to install ONLY the display drivers for
your product (in this case the STB Vision 95 interface and features
described in this file are not installed).  The system will copy the
drivers and STB Vision 95 files from the release disk or directory to
your system and return you to the Change Display Type dialog.

At this point, you should look at the selected monitor in the Monitor
Type group and change it if it does not match the monitor you have
attached to your system.  To change the monitor, select Change in the
Monitor Type group, then select Show all devices on the Select Device
dialog, then select your monitor manufacturer and model and select
OK.  Finally, select Close on the Change Display Type dialog, select
your initial Display Setting on the Display Properties / Settings
dialog, then select Close, then select Yes to restart your computer.

After your computer and Windows 95 restart, your initial Display
Setting should be active and the STB Vision 95 Control Panel will
start.  If for some reason Windows 95 does not successfully restart
and you suspect that you may have an invalid display configuration,
see section 8 of this file for information on how to recover.

The STB Vision 95 Control Panel, STBVISN.EXE, is used to configure
STB Vision 95.  It starts automatically the first time Windows 95
restarts after installing STB Vision 95.  It selects a default
Refresh Rate Limit that is suitable for your selected monitor and it
starts the Monitor Options dialog, where you must select OK or Apply
to test the selected Refresh Rate Limit.  At this point, you are
returned to the STB Vision 95 Control Panel, where you select your
display setting and start and configure the STB Vision 95 features.

Context-sensitive help information is available for STB Vision 95 by
selecting the 'Help' button on any STB Vision 95 dialog, or from the
system menu on any STB Vision 95 window.  Also, this README.STB file
containing information specific to your STB product can be viewed by
selecting the 'Read Me' button on the Control Panel.


6. Selecting a Monitor and Controlling Vertical Refresh Rates
-------------------------------------------------------------

The Windows 95 Display Properties / Settings dialog is where you
select a monitor.  For instructions on how to start Display
Properties / Settings, see section 4 of this file.

To select a monitor, select Change Display Type from the Display
Properties / Settings dialog, then select Change from the Monitor
Type group of the Change Display Type dialog, then select Show all
devices or Have Disk from the Select Device dialog, then select your
monitor manufacturer and model and select OK.  Finally, select Close
on the Change Display Type dialog and on the Display Properties /
Settings dialog, then select Yes to restart your computer (if you are
prompted to do so).

It is important that you select the correct monitor for STB Vision 95
to be able to take full and correct advantage of your STB product.
If your exact monitor does not appear in the Windows 95 monitor list,
then select a monitor that has the same or similar capabilities to
your monitor.  STB Vision 95 uses the capabilities of the selected
monitor to allow only values for Desktop Area, Resolution, and
Refresh Rate Limit that are supported by that monitor to be selected.

The STB Vision 95 Monitor Options dialog is where you control
vertical refresh rates.  To start the Monitor Options dialog, click
button 1 or 2 on the Monitor Options icon on the STB Vision 95
Control Panel or Icon Toolbar.

STB Vision 95 uses the concept of a Refresh Rate Limit to control
vertical refresh rates.  Each potential Resolution you may run has an
associated Refresh Rate Limit.  STB Vision 95 will run your selected
display setting at the highest available refresh rate supported by
your product for that Color Palette and Resolution that is less than
or equal to the specified Refresh Rate Limit.

To select a new Refresh Rate Limit for your current Resolution, click
button 1 in the Refresh Rate Limit list box and select the new value,
then select OK or Apply to activate it.  The new limit will be put
into effect and you will be asked to accept or reject it.  A mode
switch will occur, if necessary, to switch to the highest vertical
refresh rate for the current display setting that is less than or
equal to the new limit.


7. Updating Existing STB Vision 95 Releases
-------------------------------------------

You can update existing STB Vision 95 releases for the same STB
product by installing the new STB Vision 95 release "over the top of"
the previous release.  This will overwrite any previously existing
files that have the same name as files in this release, and your STB
Vision 95 configuration (i.e. display setting and feature options)
will be reset to the default state.  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, using the packing list file names in
the previous release's README.STB file.


8. Recovering from an Invalid Display Configuration
---------------------------------------------------

When the Windows 95 display configuration is completely invalid,
Windows 95 is either unable to run or you cannot see what it is
displaying, and therefore you are unable to run the STB Vision 95
Control Panel or the Display Properties / Settings dialog in order to
select a new (hopefully valid) display configuration.

When the Window 95 display configuration is partially invalid,
Windows 95 will usually run in its "safe mode", where you are
restricted to 640x480 resolution and 16 colors, and you cannot take
full advantage of your STB product.  In the partially invalid display
configuration case, you can at least run the Display Properties /
Settings dialog to try to select a valid configuration, or to
reinstall STB Vision 95.

There are many things that can cause an invalid display
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 selecting the new monitor from
the Display Properties / Settings dialog and using the STB Vision 95
Monitor Options dialog to select a new Refresh Rate Limit.

To recover from a partially invalid display configuration (Windows 95
only runs in "safe mode"), first attempt to select a new display
setting from the Display Properties / Settings dialog.  For
instructions on how to start the Display Properties / Settings
dialog, see section 4 of this file.  If this does not work, then
attempt to reinstall STB Vision 95.  For instructions on how to
reinstall STB Vision 95, see section 5 of this file.

To recover from a completely invalid display configuration you must
force Windows 95 to run in "safe mode".  If your system normally
automatically starts Window 95, you force Windows 95 to run in safe
mode by pressing F5 while the "Starting Windows 95" message is
visible, or while the "Microsoft Windows 95 Startup Menu" is visible.
If you normally start Windows 95 from the command line, you force
Windows 95 to run in safe mode by using the "WIN /D:M" command to
start Windows 95.  Once Windows 95 is running in safe mode, follow
the instructions in the above paragraph for recovering from a
partially invalid display configuration.


9. The STB Vision 95 Configuration
----------------------------------

The STB Vision 95 configuration is stored in the STB*.INI and
STB*.MOD files, and the Windows 95 SYSTEM.INI file and registry.  The
STB*.* files are installed into your Windows 95 directory.  When you
use the STB Vision 95 Control Panel to change your STB Vision 95
configuration (i.e. display setting and feature options), the
STB*.INI file and the registry are updated to reflect your changes.

Do not manually edit or delete the STB*.* files, or the display
related sections of the registry, as by doing so you risk corrupting
your STB Vision 95 configuration and your Windows 95 display
configuration.  Should your configuration be accidentally corrupted,
you may be able to correct it by running the STB Vision 95 Control
Panel and/or the Display Properties / Settings dialog and selecting a
new display setting.  If this does not correct the problem, see
section 8 of this file for instructions on how to recover.

--------------------------                     

There are no miscellaneous utilities included with this release.


D. Miscellaneous Issues
-----------------------

Controlling Vertical Refresh Rates Without STB Vision 95:

How you control vertical refresh rates when running without STB
Vision 95 varies by product.

For Cirrus-based products (Horizon, Horizon+, Horizon Video,
Horizon 64 VL, Nitro 64) and S3-based products (PowerGraph Pro
PowerGraph 32, PowerGraph 64, PowerGraph 64 Video, Velocity 64V), run
the supplied DOS utility from the DOS command line outside of Windows
95.  For Cirrus-based products, the utility is CLMODE.EXE.  For
S3-based products, the utility is S3REFRSH.EXE.  These utilities are
included on the Driver / Utility disk for your product.

For Sierra-based products (Horizon 64 PCI), you must manually edit
the appropriate values in the Windows 95 registry using REGEDIT.EXE.
REGEDIT.EXE is included with Windows 95.  Start REGEDIT.EXE using the
Windows 95 Start / Run menu command.  Open the HKEY_LOCALMACHINE \
System \ CurrentControlSet \ Services \ Class \ Display key.  Locate
the subkey for your product.  Under that subkey, open the MODES
subkey.  Open the subkey for the resolution you want to set the
refresh rate for, for example, 1024x768.  Set the 'Refresh' value for
this subkey to one of the supported refresh rates, for example,
'75Hz'.  Be sure to set the value to a string that exactly matches
one of the supported refresh rates.  Restart Windows 95 to activate
the new refresh rate.  If your monitor does not sync with the new
rate, start Windows 95 in "safe mode" and select a lower refresh
rate.

DDC Monitor Support on PowerGraph 64 VL:

By default, DDC monitor support is enabled on the PowerGraph 64 VL
under Windows 95.  This can cause a problem on some system boards.

Windows 95 calls the DDC BIOS functions to obtain the DDC monitor
information.  There are several VL system boards on which the DDC
BIOS calls can require approximately 2 minutes to complete.  During
this period when Windows 95 is starting up, your system appears to be
hung, but it is not.  Eventually the call will complete and Windows
95 will start.

You can correct this problem by manually editing the STBDISP.INF
file and reinstalling the PowerGraph 64 drivers, with or without
STB Vision 95.  Be sure to create a backup copy of the file
before editing it, in case the file is corrupted during editing.

Perform the following steps:

1. Edit the STBDISP.INF file with an ASCII text file editor.

2. Search for a line containing 'stbpg64.vxd' (the quotes are
   NOT part of the text you are searching for).

3. Two lines below the line on which you found 'stbpg64.vxd'
   the following line should appear:

     HKR,DEFAULT,DDC,,1

   Place a ';' (semicolon) at the beginning of this line to
   comment it out.

4. Repeat steps 2 and 3.  There may be more than one occurance
   that needs to be changed.  Change them all.

5. Save the new STBDISP.INF file.

6. Reinstall the PowerGraph 64 drivers.
