IBM* SVGA Support Diskette for Cirrus Logic** 542X
It is recommended that you print this README file prior to proceeding.
This README provides instructions to:
o Install the needed files with DOS Version 5.1 or later installed
o Use the CLMODE utility
o Install the needed files with OS/2* 2.11 or later installed
o Install the needed files with Windows** Version 3.1 installed
UTILITIES FOUND ON THIS DISKETTE
--------------------------------
CLMODE: The CLMODE program consists of two files: CLMODE.EXE
and CLMODE.DAT. It allows the user to identify the type
of display attached to the SVGA Adapter, and it allows
you to select the refresh rates that the SVGA Adapter
must use when the extended modes are selected. This
program is used in the DOS and OS/2 environments.
CLMINST: This DOS program installs the CLMODE files in the DOS
root directory of the drive you specify.
SETRES: This program performs the CLMODE functions from
within Windows.
INSTALLING THE NEEDED FILES WITH DOS VERSION 5.1 OR LATER INSTALLED
-------------------------------------------------------------------
1. Turn on the computer and the display.
2. Insert the IBM SVGA Support Diskette in drive A.
3. Copy the CLMODE.EXE and CLMODE.DAT files to the root directory
or to a directory of your choice.
Note: The CLMINST.BAT file, included on this diskette, copies
the required files to the root directory. You can copy
the files to another directory as long as the files are
in the same path.
- To copy the files to the root directory, at the command
prompt, type A:CLMINST A: C:
(where C: is the drive on which DOS is installed)
Then press Enter. The files will be copied to drive C.
- To copy the files to another directory, use the COPY
command to copy the CLMODE.EXE and CLMODE.DAT files
to the directory of your choice.
USING THE CLMODE UTILITY
------------------------
At the command prompt, type CLMODE and press Enter.
The main window, which consists of a number of buttons, will appear.
Each button represents a different option or menu. Information
concerning the SVGA Adapter, such as the controller type, the
BIOS version number and the amount of video memory present,
appears on the right side of the window.
Note: If you want to use a mouse with CLMODE, you must install
a mouse driver before you start the CLMODE Utility.
Select the Monitor Type button. The Monitor Type window will appear.
Use the cursor keys or the mouse to select the type of
display (monitor) attached to the SVGA Adapter.
Note: Selecting the Advanced monitor type will enable you to
customize the display timings for the display you are
using. Refer to the table that follows for a partial
list of display types.

The Set Advanced button allows you to customize the monitor
timings. Use the mouse or the Tab key to select it after you
select the Advanced monitor type. This brings up a new
box with menus for each available resolution. Select the
desired refresh rate for each resolution. Consult the manual
for your display for the correct resolution and refresh rates.
Before saving the new monitor type, you should select the
Verify button to view each of the new video timings
that you selected and to verify that the new settings are
compatible with your display.
After each test screen appears, press Enter or the left
mouse button to view the next video mode.
If there is a problem, press Esc or the right mouse button
to return to the Monitor Type Setup box. Select a
slower refresh rate for the resolution that failed to perform
correctly; then verify your choices again. Once you are sure
that everything is correct, press the Save button to set the
new monitor type. Press the Cancel button to discard any
changes. Press the Help button to get a detailed explanation
on the monitor types and the refresh rates.
When you use command line options for CLMODE.EXE at the DOS
prompt, the menu-driven windows will not appear. Instead,
configuration, monitor type, video mode, and refresh rate will
be set at the DOS prompt. The command line options for CLMODE
are as follows:
CLMODE {modenum} {m{montype} | {s n} }[Enter]
Where:
{modenum} mode number
{montype} monitor type
Monitor type:
0 VGA
1 8514
2 Super VGA
3 Extended Super VGA
4 Multifrequency
5 Extended Multifrequency
6 Super Multifrequency
7 Extended Super Multifrequency
{montype} monitor type
t6=x(Hz) 640x480 @ (0 = 60, 1 = 72)
t8=x(Hz) 800x600 @ (0 = 56, 1 = 60, 2 = 72)
t1=x(Hz) 1024x768 @ (0 = 87i, 1 = 60, 2 = 70, 3 = 72)
t2=x(Hz) 1280x1024 @ (0 = 87i, 1 = Not available)
s List status information.
For example, to set video mode 3:
type CLMODE 3 and press Enter
For example, to select custom monitor timings with 640x480 at
60Hz and 800x600 at 72Hz refresh type:
type CLMODE t6=0 t8=2, press Enter
If this selection is always desired when entering DOS or
Windows, add the statement (CLMODE t6=0 t8=2) as the last
line in the AUTOEXEC.BAT file.
Typing an invalid option will display the command line help
text. Typing S as a command line option will display the
current CLMODE settings.
