3.0 Utility software

There are utility programs which are supplied with your VC921 VGA. The
following section describes these utilities and how to use them. CLMode is
a program supplied with your VC921 VGA to configure it's various options.
The TSRFONT utility will make a full 8x14 size character set available to
programs that bypass the BIOS and directly draw characters to the screen.

3.1  CLMode

The CLMode utility allows the user to define the type of monitor attached,
set the video mode timings supported by the VC921 VGA and preview them.
Note that to use a mouse, a mouse driver should be installed prior to
running the CLMode utility.

3.1.1  Using CLModes graphic interface

CLMode requires that the computer have 300KB of standard memory and 10MB
of extended or expanded memory available for it to run. "CLMode" can be
used in two ways:

1. "CLMode" is in Utility/Drivers CD Title. You have to run README.BAT in
   Utility/Drivers CD Title, type "G" ENTER for CIRRUS GD5430, and type
   "C" ENTER, then type "y" to change to subdirectory UTIL.
2. When Windows driver has been intalled. "CLMode" is in C:\Window\VGAUTIL
   directory.

   At the DOS prompt type:    CLMODE  [Enter]

When CLMode starts, it will blank the screen for a couple of seconds.
During this time, CLMode is attempting to identify the monitors
capabilities using the VESA Display Data Channel (DDC). In its graphics
mode, CLMode looks and works just like a Windows application.

The main window is used to select and configure the monitor that you have
connected to the graphics adapter. Select the brand and model of the
current monitor using the two dropdown boxes. To get a scrollable list of
available choices, click on the down arrow with the mouse. For keyboard
only, hit the [Tab] key until the Monitor Brand field is highlighted, and
use the cursor keys to move through the choices. If the correct brand is
not available select "Other Brand". Move to the "Monitor Model" field and
select from the list provided. If "Other Brand" was selected then the only
choice will be "Other Monitor". If the monitor is not on the list select
"Other Model".

If the graphics adapter and the monitor both support VESA Display Data
Channel, this will be the default choice. This means that CLMode was able
to identify the monitor and knows what resolutions and refresh rates are
available for the monitor. Select the refresh rate for each resolution.
If the monitor was selected by name, then selecting the highest refresh
for each resolution will give the highest quality display.
If "Other Brand" or "Other Model" was chosen, consult the  manual that
came with the monitor to determine the proper refresh rates.

At the bottom of the screen are six buttons. Each button represents a
different option or window. The underlined letter of a button name
specifies the hot key combination for that item. For example, press the
[Alt] and the underlined letter keys simultaneously.

In the lower right corner of the main window is configuration information
about the graphics system. The information details the VGA BIOS version,
the total display memory of the graphics controller, whether or not an
EEPROM is present, and whether or not a centering TSR is loaded. This
information is useful when installing software or getting technical
support.

Preview video modes

Select the Preview button. The Video Modes Preview window displays a list
of all of the modes supported based on the currently selected monitor
timings and the amount of video memory present. This list of video modes
will tell you which are available in your current configuration for use
with extended resolution drivers. To see what different video modes look
like on your monitor, select the Show button. After each test screen is
displayed, press [Enter]. If you don't want to see any more video modes
pressing [Esc] will return you to the Video Modes Preview window.

Centering adjust

Centering is available while in Video Modes Preview (only for extended
Graphics modes 58h and greater). While previewing a video mode, you have
the option to use the Right/Left/Up/Down arrow keys to adjust your screen
accordingly. The screen adjustments have predefined limits, and in some
cases, the limit for the right side adjustment for some modes will have
already been reached when entering the Preview mode.  In that case, no
right side adjustment will be allowed. Once a mode has been adjusted, the
new values for horizontal and/or vertical positioning are saved within
CLMode.

When exiting from CLMode, you are prompted on whether you want to save
these new parameters to the TSR (CENTER.COM). If you choose to do this,
the values to be used for the adjusted modes are stored in CENTER.COM on
exit. CENTER.COM can then be loaded outside of CLMode.  Once this is
accomplished, all of the modes which you have adjusted will be the active
modes set when that mode request is made. To unload CENTER.COM, you must
change the monitor type currently set in CLMode. This will unload
CENTER.COM and uninstall all centering adjustments previously redefined.

An additional adjustment for monitor SYNC POLARITY is also available while
centering is active. To adjust the polarity of the current mode, simply
press the PgUp or PgDn keys (while in Preview) to cycle through the
available options, (Vertical Sync Polarity/Horizontal Sync Polarity):
          +/+, +/-, -/+, -/-
Note: Centering will not be allowed if CENTER.COM has been loaded. You
must unload CENTER.COM before attempting to save new adjustments.

Limitations: You may only adjust and save 16 modes at a time to
CENTER.COM.

The information in the main window displays the VGA controller type, the
BIOS version number, and the amount of video memory present.

Getting help

Selecting the Help button from the main window will display instructions
on using CLMode.

Information about CLMode

Selecting the About button will display version and copyright information
about CLMode.

Undoing changes

To return all settings to their state when CLMode was started, select the
Undo button.

Exiting the CLMode

To exit CLMode at any time, press the [Alt] and [F4] keys simultaneously,
or click the left mouse button on the system button of the main window
(i.e., the top left corner button of the window which is shown as a dot),
or select the Exit button. CLMode will ask if the changes should be saved
in the AUTOEXEC.BAT. In most cases, the end user should answer yes.
Answering no means that the next time the computer is booted, all of
CLMode's configuration information will be lost.
When the CLMode utility exits, the currently selected monitor brand,
model, timings, and centering information will be saved. The current
monitor timings will be displayed.

3.1.2  Using CLMode's command line options

When command line options for CLMODE.EXE are given at the DOS prompt, the
menu-driven windows will not be displayed. Instead, configuration, monitor
type, video mode and refresh rate will be set at the DOS prompt.  To
display the available command line syntax for CLMode, type:

                  CLMODE /?[Enter]

Typing an invalid option will display the command line help text. Typing
[S] as a command line option will display the current CLMode settings.

3.2  TSRFONT driver

Some DOS application programs bypass the BIOS and directly draw characters
to the screen. Programs which directly draw characters using the 8x14 font
from the BIOS will appear to be writing incorrect data to the screen.
Typically this can occur in programs which offer a selection to use a
graphics 25 or 34 line display mode.  Other programs may appear to cut off
the descenders of characters like "y" and "j".

Running the TSRFONT driver will make a full 8x14 size character set
available to these programs, and should correct display errors discussed
above which were observed in these programs. To run the TSRFONT driver,
type TSRFONT [Enter]. If you want to run it automatically when you turn on
your computer, add it to your AUTOEXEC.BAT file.

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

4.0 Driver Installation

4.1  Microsoft Windows 3.x

The Windows 3.x driver installation utility copies all of the graphics
driver and utility files to your hard disk. It also allows you to
configure your graphics system for Windows 3.x in either DOS or original
OS/2 v2.1. You can change the monitor refresh rates, resolution, number of
available colors, large or normal size fonts and font cache size.

After new options have been selected, you can either immediately restart
Windows, in which case the new configuration will take effect immediately,
or you can continue working in the current resolution, in which case the
new resolution will take effect the next time Windows is started. In some
configurations the AUTOEXEC.BAT file needs to be modified to make the
changes permanent.

The display drivers support both Windows versions 3.1 and 3.11 and also
Windows for Workgroups version 3.11. Because these drivers were written
and optimized for performance, they were written to use a linear address
for the display buffer and run in protected mode. To load the display
drivers with Windows 3.11 or Windows for Workgroups 3.11, you must install
the VGA driver first before installing these display drivers. The display
drivers will only run in enhanced mode and not in standard mode. Original
OS/2 2.x is non-upgraded to support high color and true color display
drivers.


4.1.1  Using Install

To run the installation program, start Windows 3.x. Insert the
Utility/Drivers CD Title into your CD-ROM drive. From the Windows Program
Manager select Run from the File menu. Type the letter of the CD-ROM drive
that the Utility/Drivers CD Title is in, followed by the word install. For
instance, if the Utility/Drivers CD Title is in drive D:, type
D:\README.BAT, type "G" ENTER for CIRRUS GD5430, then you can see which
subdirectory the Windows 3.x drivers is in. Then from the Windows
Program Manager type INSTALL.EXE with the Windows 3.x drivers directory
pathname. Click on the OK button.

In the first dialog box that is displayed, you can set the path where you
would like the utility programs to be installed. If you want to use the
default directory, click on Continue. To change to another directory, you
can either type the path name or you can click on the down arrow and
select a directory for installation. The drop down box works just like the
Directory field in a file open dialog box. After you select the directory,
press the Continue button. After the drivers have been copied to your hard
disk, the install program will execute the WinMode utility.

After the extended resolution drivers and utilities have been installed,
they can be reconfigured from within Windows 3.x using Windows Setup,
WinMode, or from the DOS prompt.

Resolution

These buttons let you choose the resolution that WinMode will use to run
Windows 3.x after Windows is restarted. Some of these buttons may be
unavailable because of the amount of video memory in your system or if
some of the monitor refresh rates have been set to Unavailable.

Colors

These buttons let you choose the number of colors that will be available
to Windows 3.x after Windows is restarted. Some of these choices may be
unavailable. This is because of the amount of video memory in your system
and the resolution that you have selected. If you have chosen OS/2 v2.1 in
the Operating System field, then the only possible choices are for 16 or
256 colors. Generally, 256 color mode will be the fastest choice. If you
need more colors then there will be some slowdown in graphics performance.

Font Size

The small fonts are intended for lower resolutions and higher resolutions
on large monitors. With smaller monitors, the large fonts are more
readable at higher resolutions.

Monitor brand

Select the brand of your monitor from the list provided in the drop down
box. This will change the list of monitors in the Monitor Model drop down
box to display only the models available under the selected brand. If your
monitor brand is not listed, select Other Brand.
If your graphics adapter and monitor both support VESA Display Data
Channel, this will be the default choice. This means that WinMode was able
to identify the monitor and knows what resolutions and refresh rates are
available for the monitor.

Monitor model

Select the current model from the list first presented. If your monitor
is not listed select Other Monitor. If your graphics adapter and monitor
both support VESA Display Data Channel, this will be the default choice.
This means that WinMode was able to identify the monitor and knows what
resolutions and refresh rates are available for the monitor.

Monitor Refresh Rates

The drop down list boxes let you select the monitor refresh rates for each
resolution. If you select Unavailable for any screen resolution, any
higher resolutions will also be unavailable. This will also turn off the
corresponding choices in the Resolution box.

In general, the higher the refresh rate, the better the display quality
and the lower the performance. This is because the graphics system can
only do a fixed number of operations per second. The more time it spends
redrawing the screen, the less time it has available to perform other
operations. Consult the manual that came with your monitor to determine
the proper settings for these fields.

Font Cache Size

The Font Cache Size lets you set the amount of system memory that will
be available for font caching. Next to the font cache size is an up arrow
and a down arrow. Click on the up arrow to increase the cache size. Click
on the down arrow to decrease the cache size.

Font caching is a technique to increase the performance of Windows by
saving the bitmaps of frequently used characters. Normally, when a
character is displayed on the screen it first is created from the Truetype
outline then it is copied to the screen. A cached character has already
been created and stored and so it is just copied as needed.

WinMode has tried to determine the correct setting for this field for you,
but you may change it. Just remember that memory set aside for font
caching will not be available for Windows program and system usage.

Operating System

The Operating System buttons let you set the operating system in which
you are running Windows.

This is very important because the configuration and capabilities of the
drivers are very different in OS/2 v2.1 and DOS. The most obvious
difference is that the drivers will only work in 16 and 256 color modes
in OS/2. There are a number of other differences in the configuration of
the drivers.

Prior to installing OS/2 For Windows, you will need to run WinMode and
select the OS/2 v2.1 option.

OK
--
The OK button closes the dialog box and accepts the choices that you have
made.

After clicking OK, your computer will be reconfigured to use the choices
that you have made. These changes may need to be added to your
AUTOEXEC.BAT file for them to be permanent. If this is necessary, you
will be prompted by the program.

If WinMode detects that you have changed your Windows 3.x configuration,
you will be asked if Windows should be restarted. If you answer yes,
Windows will be restarted immediately. If you answer no, you can continue
to use Windows, however the changes will not take effect until Windows is
restarted.

Cancel
------
The Cancel button closes the dialog box and exits the program without
making any changes. Selecting About

The About button will display a dialog box with the version number of
WinMode and a copyright notice.

About
-----
The About button will display a dialog box with the version number of
WinMode and a copyright notice.

Help
----
For help on WinMode, select the Help button. The main help screen contains
an image of the WinMode screen. Place the cursor over the field(s) that
you need help with. When the mouse pointer changes to a hand, click to
display the help text for that field. Click again to make the pop-up text
disappear.

After the extended resolution drivers and utilities have been installed,
they can be reconfigured either from within the Windows 3.x Control Panel
or from the DOS prompt.

4.1.2  Reconfiguring Windows 3.x

If you are in Windows, run WinMode to reconfigure the Windows 3.x drivers.
Please refer to the Driver Installation section for information on
Microsoft Windows 3.x. If you are in DOS, proceed as follows to
reconfigure the Windows 3.x drivers.

1. Ensure that Windows 3.x and the extended resolution drivers are already
   installed on your computer.
2. From your Windows directory, at the DOS prompt, type SETUP[Enter] to
   run the Windows SETUP.EXE program. Follow the instructions on the
   screen. When you come to the screen which lists the hardware and
   software components such as display adapter (e.g. VGA, CGA, etc.),
   keyboard type, mouse type, etc., go to the Display selection by using
   cursor keys to move the highlighted bar and press [Enter].
3. You will see the list of drivers and their associated resolutions.
4. Highlight the desired choice by moving the cursor to the correct
   display driver, and then press [Enter].
5. Setup will prompt you that the driver is already in your Windows
   directory and give you a chance to replace it. Use the existing driver.
6. Continue with the remainder of the setup procedure.


4.1.3  To turn on/off DDC detection support

To turn the DDC detection support on or off, the following changes need to
be made to the WINMODE.INI file.

To turn on DDC detection support:         MakeDdcCall=on

To turn off DDC detection support:        MakeDdcCall=off

To turn the resolution-change-on-the-fly support on or off, the following
changes need to be made to the WINMODE.INI file.

4.3  Power management screen saver

4.3.1 About the screen saver

The Display Power Manager for Windows 3.x provides a mechanism to control
the amount of power used by a computer's monitor.  It provides a total of
5 levels of power savings.

The first level is a conventional screen saver that turns the screen black
and bounces a logo around. The black screen provides substantial power
savings and the animation lets you know that the computer is still active.

The other four levels of power savings are...

Reduced on mode - Reduced on mode is an optional power saving state that
allows the computer to use some power savings while still fully
operational. Currently this is limited to some portable computers that can
lower the power usage on their LCD displays. This causes some degradation
of display quality.
Stand by mode - Stand by mode is an optional power saving state that gives
minimal power savings, but provides the fastest recovery time.

Suspend mode - Suspend mode is a mandatory state in which substantial
power savings are achieved by the display. The trade off is that recovery
times are longer than from stand by mode.

Off mode - Off mode provides the highest level of power savings and the
longest recovery times. With this mode the display is actually turned off
so that recovery times are equivalent to switching the monitor on.

They match the power saving modes defined by the VESA VBE/PM (see below)
standard. As you move down from one mode to the next, the amount of power
being saved is greater, but so is the amount of time that it takes for a
monitor to recover and be ready to display data.

The screen saver will cycle through all of the selected power saving modes
one after another until the maximum selected power saving mode has been
reached. The number of minutes that is specified for each level is the
number of minutes after the previous mode has been enabled. It is not the
total time before entering that mode.

Using the Windows Control Panel, select Desktop. In the group Screen Saver
within the Desktop dialog box, select the Screen Saver named Display Power
Manager. Select the desired delay before entering a power saving mode.
Select Setup to further configure the power saving options. The following
sections describe these options. For further information on setting up
Windows screen savers, please refer to the Windows User Guide.

4.3.2  Special considerations

Some of these power saving modes are intended for specific display types,
so not all of them are available on all video controllers. On some
controllers, only the animated logo will be available. For the power
saving modes to have any effect beyond just blanking the screen, the
monitor being used must have specific power saving features.

Note that if the screen saver is in any of the power saving modes, moving
the mouse will not wake it up. This is different from normal screen savers
and is used to keep the monitor from waking up because of accidents such
as bumping the desk that the computer is sitting on. This is especially
important if the password option is enabled, since once the password
dialog box pops up, it stays there until the user turns it off. This is a
limitation of the Windows 3.x screen saver interface.

4.3.3  Using the screen saver

When the screen saver is started, it will initially display a bouncing
logo on a black background. To enable additional levels of power savings,
select them from the Screen Saver Mode section of the Setup dialog box.

4.3.4  Screen saver mode

The Screen Saver Mode section has four check boxes in it. They are
ReducedOn, StandBy, Suspend and Off. The screen saver detects the type of
graphics controller that is being used and the types of power savings that
it is capable of.

If the text immediately to the right of any of the check boxes is
unavailable, that option is not available. If a power saving mode is
available, then the text immediately to the right of the check box is
black. If the box is selected with the mouse or the keyboard, the rest of
the fields on the line will also turn black. If the check box is
deselected, the other fields will turn gray.

The minutes field for each line can be changed only if the check box for
that line is selected. The amount of time can be set for any number
between 1 and 60. The number can either be typed directly, or by clicking
on the up or down arrow next to the number. Holding the mouse button down
on the arrow will quickly increase or decrease the minutes field.

The number of minutes that is specified for each level is the number of
minutes after the previous mode has been enabled. It is not the total
time before entering that mode.

4.3.5  Screen saver animation speed

The scroll bar controls how fast the animation moves. The checkbox
controls whether or not a bouncing sound will be played whenever the logo
hits an edge of the screen.

4.3.6  Password options

If the password checkbox is enabled, then the screen saver will prompt the
user for a password before it quits. The password is the same one that is
used for other Windows 3.x screen savers.

4.3.7  The Energy Star program

Energy Star is a program created by the US Environmental Protection
Agency (EPA) to promote energy efficiency. The goal of this program is to
lower electricity usage by making computers and related hardware more
energy efficient.

Computers currently use an estimated 5% of commercial electricity
consumption. If no actions are taken, this could rise to 10% by the year
2000. Ironically, much of this electricity is wasted. Research shows that
the vast majority of time personal computers are on, they are not actively
in use. Additionally 30% - 40% are left running at night and on weekends.

Electricity generation accounts for 35% of all U.S. emissions of carbon
dioxide - the most prevalent greenhouse gas. It also accounts for 75% and
38% of all U.S. emissions of sulfur dioxide of nitrogen oxides
respectively - the two pollutants most responsible for acid rain.

By using more energy-efficient equipment in our homes, offices and
factories, we can reduce this pollution - while saving money.

The Energy Star logo is used to mark computers, peripherals and software
that have adopted the EPAs power saving guidelines.

4.4  Microsoft Windows 95

MS Windows 95 provides lots of VGA drivers, and Cirrus Logic GD5430/34
driver is included.

If you want to use extended mode, please see Windows 95 user's guide refer
to VGA drivers installation.
