DOS Display Drivers and Utilities

Installing the CLMode and TSRFONT Utilities

CLMode and TSRFONT use the same install program described below.
IMPORTANT NOTE: CLMode is a DOS utility and should only be run from the DOS
                prompt and not under an application shell such as Microsoft
                Windows 95, Windows NT, and Windows 3.1 or IBM OS/2.

        1. Place the driver cdrom-disk into cdrom-driver "d:"
        NOTE:  To use a mouse, a mouse driver should be installed prior to
               running the CLMode utility in order to use the mouse pointer
               for button selection.
        2. change a directory "5465_AGP\dos_util"
        3. copy all the files into your hard-disk

Reconfiguring the CLMode Utility

To reconfigure the CLMode utility once it has been installed, type the
following where you installed the card utilities or at the default C:\CLUTIL
directory:

        CLMODE [Enter]

The main pop-up dialog box (Screen Refresh Setup) consists of a number of
buttons.  Each button represents a different command, option or list.

The underlined letter of a button name along with the [Alt] key specifies the
'hot' key combination for that item.  For example, pressing the [Alt] and the
underlined letter keys simultaneously selects an option.

The various options you can configure in CLMode are described below.

IMPORTANT NOTE:  The Options button, used with specific chips and
configurations, is not available for use.

Viewing the Current VGA Controller Status

The information in the main CLMode dialog box displays the BIOS version number,
the amount of video memory present, whether or not EEPROM is present, and
whether or not the Centering TSR is loaded.

Getting Help and Information

CLMode provides on-line help for selecting the correct video modes by clicking
on the Help button in the Screen Refresh Setup dialog box. The Video Modes
help window defines the information displayed in the dialog box. If you want
to know what version of CLMode you are using, clicking the About button
displays a window with the CIRRUS LOGIC copyright message and the CLMode
version number.

Selecting and Configuring the Monitor Type

Selecting the proper monitor type allows the CIRRUS LOGIC VGA to display the
highest quality output that it is capable of with the attached monitor.  The
monitor type determines what video modes are available to your system.  It
also determines the vertical refresh rates available.  Generally, the
higher the refresh rate, the better the screen will look.

To quickly search for your monitor in the Screen Refresh Setup dialog box,
press the first letter of your monitor name and use the down arrow key to
scroll through the alphabetical listing. If you cannot find your monitor in
the list presented, scroll to the bottom of the list and select Other.
Once you have chosen a monitor brand, select a monitor model by clicking on
the Monitor Model scroll button to make your model selection. Depending on
the monitor and monitor model you selected, the monitor refresh rates change
accordingly. By clicking on the Set Highest button, CLMode automatically
determines the highest refresh rate for your monitor and selects it. If you
want to select different refresh rates, click on the Monitor Refresh Rates
scroll buttons to choose from the other refresh rates available for your
monitor and model selection.

Previewing the Video Modes

Before saving the new monitor type, you may want to select the Preview button to view each of the new video timings that you have selected, verifying that they are compatible with your monitor.  Select the Preview button in the Screen Refresh Setup dialog box by pressing the [ALT] and V hot key combination.  The Modes Preview window displays all the modes supported according to the monitor type attached 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] to view the next video mode screen.  If you do not want to see any more video modes, press [ESC] to return to the Modes Preview window. Press the Quit button to go back to the Screen Refresh Setup dialog box.
If there is a display problem when viewing your test screen, press [ESC] to
return to the Screen Refresh Setup dialog box.  Try a slower setting for the
resolution that did not work and try verifying your choices again.
IMPORTANT NOTE:	When using a memory manager, you should be aware that using
the memory range B000 - B7FF (which is the industry standard monochrome card
address space) will conflict with monochrome modes. The conflict could occur
even if you are not using a monochrome monitor but are using an application
such as CLMode, Microsoft Windows compatibility tests, HIMEM, EMM386 and QEMM.
When using these applications, your memory manager could go into monochrome
mode and cause your system to hang. If this is the case, reroute to another
memory range.

Centering the Display

Display Centering lets you center your monitor's display area by using the
arrow keys to move the display area up and down, and from side to side.
There are also instructions for centering your display in the Preview dialog
box. The Preview dialog box provides a list of available video modes. Select
a mode and click on the Show button. If your screen does not display the
test pattern, press the [Escape] key to return to the Preview dialog box.
You will need to select a lower refresh rate for any resolution that did
not display properly during the preview selection process.  When you are
satisfied with the resolution and how your display is centered on your
monitor's screen, select the Quit button to return to the previous screen.


Exiting the CLMode Utility

If you want to discard any changes before exiting and revert back to the last
saved monitor setting, press the Undo button. You can exit CLMode at any time
by pressing the [Alt] and [F4] keys simultaneously, clicking the top left
corner mouse button of the main window, or selecting the Exit button. If
you have made setting changes in CLMode, upon exiting CLMode an AUTOEXEC.BAT
Update window appears. Choose Yes if you want to save your new settings and
update your AUTOEXEC.BAT file. Choose No if you just want to exit CLMode
and not save or update anything.

Using CLMode Command Line Options

When command line options for CLMODE.EXE are given at the DOS prompt, the
menu-driven window will not be displayed.  Instead, video mode and refresh
rate will be set at the DOS prompt.  The command line options for CLMODE.EXE
are listed below:

        CLMODE {modenum{+|*|-}} {refresh} [Enter]

Where:

{modenum{+|*|-}} = video mode number
	and		+	selects 400 scan lines (default)
			*	selects 350 scan lines
			-	selects 200 scan lines

{refresh} = monitor refresh rates

t640=x(Hz)      640x480         @       (x=60, 72, 75, 85)
t800=x(Hz)      800x600         @       (x=56, 60, 72, 75, 85,
						 0=unavailable)
t1024=x(Hz)     1024x768        @       (x=87, 60, 70, 75, 85, 0)
t1280=x(Hz)     1280x1024       @       (x=87, 60, 72, 75, 85, 0)
t1600=x(Hz)     1600x1200       @       (x=96, 60, 65, 70, 75, 80, 85, 0)

For example, to set video mode 3 type:

        CLMODE 3 [Enter]

For example, to select custom monitor timings with 640x480 at 60 Hz and
800x600 at 72 Hz refresh type:

        CLMODE t640=60 t800=72 [Enter]

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

FIX2GRAN Utility

The FIX2GRAN.EXE utility program is used to fix VESA VBE 1.2 applications
that only work correctly with a window granularity of four Kbytes. Some game
applications that need FIX2GRAN are Screamer, Terminal Velocity, and Fade to
Black. Not all game applications require the use of the FIX2GRAN utility. If
you run a VESA application and get a distorted display, you may need to run
FIX2GRAN to fix the problem.

To run and use the FIX2GRAN program, follow the instructions listed below.

1. Place the Driver cdrom-disk into cdrom driver(D:). 
2. change the directory into "5465_agp\dos_util"
3. Run the FIX2GRAN program by typing

        FIX2GRAN.exe

at the DOS prompt.

4. A message will appear on your screen:

	Old Setting was for 16K Window Granularity
	Current Setting is for 4K Window Granularity

which means that FIX2GRAN has changed the size of your window granularity for
the effective use of your application.
To set the window granularity back to the BIOS default setting of 16 Kbytes,
run FIX2GRAN.EXE again or reboot your computer.
