The MGA OS/2 PM Display Driver
v 2.10.020
Product Description
-------------------
This MGA OS/2 PM driver supports 8-bit (256 colors), 16-bit (64K colors),
and 24-bit (16M colors) display modes under OS/2 2.1 up to "Warp", in
resolutions ranging from 640 x 480 to 1600 x 1200. The driver works on
all MGA Ultima and Impression models. It also includes a Seamless Windows
driver.
Driver Installation
-------------------
To install the software, follow the procedure below:
1. If you are installing this driver for the first time, have the MGA
board installed and boot OS/2. Select VGA as the display driver.
2. If you downloaded the driver from the Matrox BBS, use the DOS LABEL
command to label your floppy as OS2.
3. Using the Command Prompts folder of OS/2, open an OS/2 Window or
Full Screen session.
4. Insert the driver disk in a floppy drive (if you are installing from
the floppy disk) or insert the CD-ROM in its drive bay.
5. Make the CD-ROM or floppy disk the active drive and type:
"SRCPATH\INSTALL",
where SRCPATH is the path which contains the MGA PM drivers.
Examples:
A:\INSTALL (if installing from a diskette with OS/2 only)
A:\OS2\INSTALL (if installing from diskette with OS/2 and NT)
D:\OS2\INSTALL (if installing from a CD-ROM)
6. You will see a dialog box in which you can select the Primary Display.
Choose "Matrox MGA Series". You may have to change the source drive
if you are not installing from drive A.
7. The installation program will then proceed with the installation.
When it is complete, you will have to shut down your system in
order for the MGA driver to take effect.
If you are installing this driver for the first time, or over a version
older than 2.00, OS/2 will restart in the default MGA resolution
(640 x 480 x 256). It is therefore advisable to select the desired
resolution immediately before rebooting, by means of the OS/2
System Setup folder, as explained in the next section.
Driver Configuration
--------------------
To change the driver mode (resolution or pixel depth), use the
following procedure:
1. Click the right button on the PM desktop background.
2. Select SYSTEM SETUP to open the system setup folder.
3. Double-click on the SYSTEM icon.
4. Select the SCREEN tab and choose the resolution/pixel depth.
You will need to reboot the system to see the change take effect.
Uninstalling the Driver
-----------------------
The OS/2 DSPINSTL.EXE program can be used to switch the display driver
from MGA mode back to VGA mode, as shown in the following procedure:
1. Open an OS/2 Text Window (or Full Screen) session.
2. Enter: CD \OS2\INSTALL
DSPINSTL
3. Select Primary Display, then choose the driver you require (for
example, VGA).
You will need to reboot the system to see the change take effect.
You may want to create an icon for the OS/2 DSPINSTL program if you plan
to use it frequently.
Note: With Warp, there are two additional ways to switch the driver from
MGA mode to VGA mode:
1. You can access a menu by pressing Alt+F1 when the OS/2 logo appears
in the upper left corner of the screen during the bootup process.
This menu will allow you to change the driver to VGA by selecting
the appropriate option.
2. You can also change the driver to VGA by running the following file
in an OS/2 window or full screen session:
\OS2\INSTALL\RSPDSPI.EXE
Your MGA OS/2 diskette also comes with an "UNINSTAL" utility. This batch
file removes lines that load the driver from your config.sys file. If used
with the "CLEAN" parameter, the driver files will even be deleted from your
hard drive. The batch file also invokes DSPINSTL so you can select another
display driver. To use the UNINSTAL utility:
1. Open an OS/2 Text Window (or Full Screen) session
2. Enter: CD \MGA\OS2
UNINSTAL
or
UNINSTAL CLEAN
Monitor Customization
---------------------
By default, the driver assumes that you have a monitor which supports
all resolutions available to your board at a 60Hz refresh rate (non-
interlaced). If you have a monitor that is capable of refresh rates higher
than 60Hz, you can perform monitor file customization with the help of the
MGAMON program. This program creates a file called MGA.INF, which contains
the appropriate video parameters for your monitor. The MGA.INF file is
read by the MGA display driver when OS/2 boots.
The MGAMON program is located in the \MGA\OS2\ directory. It is a DOS
program, so it must be run in a DOS session (either windowed or full
screen).
To run MGAMON, open a DOS session:
1. Enter: CD \MGA\OS2
MGAMON
2. Select a monitor and exit the program.
You must shut down OS/2 and reboot your computer for the changes to take
effect.
Board Testing
-------------
If you encounter any problems running OS/2 with your board, you should
first determine whether it is a system or hardware problem. The best way
to check for a potential hardware problem is to use the MGA SETUP program.
SETUP is a DOS program that is included on the MGA CAD Driver disk,
version 1.50 and later. It cannot be run from an OS/2 Command Prompt
session.
If you have a DOS (FAT) partition on your hard disk, simply install the
Setup and Utilities product using the provided installation program. Then
go to the \MGA\SETUP directory and type SETUP.
If you do not have a DOS partition, you will have to create a bootable
disk that has SETUP on it. Here is the procedure:
1. Insert the proper installation disk in your diskette drive.
2. Copy A:\SETUP\FILES1.ZIP and A:\PKUNZIP.EXE to a location on your
hard disk.
3. Make that hard disk location current and type "PKUNZIP FILES1"
to unarchive the files.
4. Remove the installation disk and format a new bootable DOS disk.
5. Copy the following files from your hard disk to your new floppy disk:
SETUP.EXE, DOS4GW.EXE, MGA.MON
6. Reboot your computer with the the new disk.
7. Type SETUP.
In SETUP, select "Graphic Mode Test" to test the various modes that
are available for your board. The program will not attempt to test a
mode which is not supported by your board. The default test will be
done at a 60Hz refresh rate for all resolutions.
If you have a customized monitor file (MGA.INF) in your \MGA\OS2
subdirectory, SETUP can read it and act upon it if you set the MGA
environment variable as shown below:
SET MGA=C:\MGA\OS2

KNOWN BUGS AND LIMITATIONS
--------------------------
The following bugs and limitations are present in this release of the
driver:
- AT (ISA) and VL boards mapped at AC000: We don't advise that you use the
(default) mapping of AC000 with this OS/2 driver. At that address, full
screen Windows does not work. On some systems with a VGA on the
motherboard, other modes could be unsupported, such as DOS in a window
and Seamless Windows.
- You will need to modify the settings of your WINOS2 Full Screen session if
your board is mapped at D8000-DBFFF (The WINOS2 Full Screen driver will not
be able to find the board). To fix this:
1. Open the settings of your WINOS2 full screen icon.
2. Turn to the session page.
3. Push the WINOS2 settings button.
4. Set the MEM_EXCLUDE_REGIONS to D8000-DBFFF.
You should do the same for all of your Windows applications running in
full screen mode.
- MGA boards with BIOS revisions older than 3.40 might experience the
following problems:
- Opening a DOS Full Screen session results in a blank screen.
- Maximizing (Alt+Home) a DOS Window results in a blank screen.
- Toggling (Alt+Esc) continuously from a Win-OS/2 full screen session
to the OS/2 PM results in a system hang.
- Only 21 lines are displayed (EGA mode) when you type MODE CO80 from
a DOS session.
All of the above-stated problems can be resolved by adding the following
line to the AUTOEXEC.BAT file:
\MGA\OS2\FIXVGA.EXE
A batch file called FIXAUTO.CMD can be used to automatically add the
above line to your AUTOEXEC.BAT file, for a permanent fix. This batch file
is installed in your \MGA\OS2 directory.
If your MGA board has a 3.40 revision BIOS (or later), make sure NOT to
use FIXVGA.EXE.
The BIOS revision may be obtained by running the MGA DOS Setup program.
- Dual-boot users should take note of this significant problem:
When rebooting for DOS using the "DualBoot" icon of the Command Prompts
folder, the system will reboot, but the MGA card will remain in a high
resolution mode, and the DOS prompt will not be visible.
Immediate workaround: reset your computer to go to DOS.
Permanent workaround: change the behavior of the DualBoot icon to make
sure that it goes to full screen mode BEFORE actually rebooting the
computer.
To do so, follow the procedure below:
1) Using a text editor, create a file containing the following two lines:
BOOT.EXE /DOS
PAUSE
Save the file as (for example) BOOTDOS.CMD in your C:\MGA\OS2
directory.
2) Edit the "settings" of the dual-boot icon.
- Click on the Session page.
- Remove the check mark from the "Close window on exit" option.
- Change the "OS/2 windows" option to "OS/2 full screen".
In the "Path and filename" field enter:
C:\MGA\OS2\BOOTDOS.CMD
instead of the current BOOT.EXE /DOS line
- The MGA OS/2 driver comes with a special keyboard driver (KBD01.SYS for
OS/2 2.1 and 2.11 and KBDBASE.SYS for Warp OS/2 3.0). This special driver
will detect a Ctrl+Alt+Del and reset the MGA board to a proper state before
the system reboots.
If you install the OS/2 2.1 Service Pack after having installed the MGA
driver, the Service Pack installation program will detect a different
keyboard driver and ask you if you want to replace it.
PLEASE DO NOT REPLACE THE KEYBOARD DRIVER.
If you accidentally replace it, simply reinstall the MGA OS/2 Driver
to restore our special keyboard driver.
- When using the DSPINSTL program to reconfigure your MGA driver, the
program states that VGA is the current driver. This is a bug in the
DSPINSTL program that is included by IBM.
- DIVE is not supported in 24 bpp by default (but Multimedia Video player
still works). If you want to enable 24bpp DIVE, please run:
\MGA\OS2\MGACONF d 1
to enable DIVE in 24bpp.
- The MMODE.EXE program included with the Setup & Utilities is not supported
in a OS/2 DOS Session.
- The MGA PowerDesk Windows drivers should NOT be used in a Win-OS/2 full
screen session. The results will be highly unpredictable.
If the MGA windows driver features are absolutely needed, then a dual-boot
configuration must be used. When booting from DOS, the PowerDesk Windows
driver features are fully supported.
