The MGA Windows Drivers and PowerDesk
Revision 2.21 (Build 027)
This diskette contains the MGA Windows Drivers and the following PowerDesk
utilities:
MGA Control Panel and Quick Access Panel
MGA Board Info and Monitor Selection Program
Other Matrox Windows Drivers and Utilities are included on the Supplemental
Disk:
MGA DCI Driver
MGA 3D Screen Saver
MGA AutoCAD for Windows Driver
MGA DynaView/3D for Windows application
This version is intended for the MGA Impression-Plus and Impression-Lite
boards. This readme file is copied to your hard disk, in the \mga\cpanel
directory.
Installation:
-------------
The installation works from VGA Windows (first-time installation) or
MGA Windows (upgrading from older version):
- Run Windows.
- Select "File", "Run", then type "A:SETUP".
- Follow the instructions. For first-time installation, the monitor program
will be automatically invoked. Selecting a monitor is highly recommended.
- For a first-time installation (from VGA), the program will reboot your
system at the end, and you must then re-enter Windows manually.
For an upgrade (from MGA 2.0x), the program will restart Windows
automatically in the selected mode.
- The installation creates a new Group called "MGA PowerDesk". Run the MGA
Control Panel to see the additional features that are at your disposal.
The monitor program is also available for further monitor tuning. The
Quick Access panel is a handy replacement for many of the PowerDesk
hotkeys.
Note: The installation may be started from DOS by changing to the floppy
drive and typing "SETUP".
The Supplemental Disk should be installed AFTER the PowerDesk Driver disk.
Modifications to the Windows .INI files:
----------------------------------------
The MGA Windows Driver installation program makes some changes to
various .INI files. The changes for the default installation (1024 X 768,
8-bit) are listed below:
PROGMAN.INI

DCI Driver:
-----------
The MGA DCI driver can be used to accelerate significantly the playback
performance of AVI files.
The DCI driver will however not be called unless updated codecs and Media
Player are also installed. A Video for Windows 1.1D Run-time upgrade is
available from Microsoft, but you can also get it from the Matrox BBS.
Known bugs, limitations and misc. notes:
----------------------------------------
- PowerDesk Hotkeys limitations:
The hotkeys (for ModeSWITCH, PixelTOUCH, etc...) MUST NOT BE USED
when running the following programs: Monitor Selection (Test & Adjust),
3D Screen Saver, or DynaView/3D for Windows (3D Viewer).
- Monitor Selection program:
The Monitor Selection program is normally aimed at selecting and testing
a monitor from our list of monitor. However an Advanced feature allows
you to interactively adjust the timings and save your changes. To use
this Advanced feature, change the "property" of the Monitor Selection
icon to start MGASET.EXE with the /A argument.
The /A (Advanced) feature of the Monitor program should not be used while
Windows is running at 1280 X 1024 X 24 resolution (which is available on
Impression-Plus boards with 4Mb of VRAM).
Moving the test screen to the extreme right or left while using
/A (Advanced) feature may result in the test screen's background color
changing to black. Pressing "U" to undo should restore the color.
Selecting Test after changing the resolution from 1024 x 768 to
800 x 600 or from 640 x 480 to 800 x 600 while in 24 bit mode will cause
the test screen to appear jittery. Changing the size, position or pixel
clock will stabilize the screen.
- Cursor problem:
The Impression-Plus exhibits noise around the cursor when running
applications which are programming the color palette in a continuous
manner. This includes the Kaleidoscope option of the AfterDark screen-
saver. A patch is available to alleviate this problem. To enable the
patch, edit your SYSTEM.INI, search for the [MGA.DRV] section, and
add the following line:
DacSync = ON
Note that this problem applies only to the 256 color driver.
- Device Bitmaps:
The MGA POWER Drivers support a feature of Windows 3.1 and 3.11 that
allows device bitmaps to be stored in MGA memory instead of in system
memory. Device bitmaps can increase the performance of MGA drivers if
there is sufficient on-board memory available. However when this feature
is activated, Windows is not 100% reliable and could cause some applica-
tions to crash. You can disable the device bitmaps feature by adding the
following line in the MGA.DRV section of your SYSTEM.INI file.
[MGA.DRV]
.
DevBits=OFF
- MGA with a monochrome card:
The MGA Windows drivers do not work when a monochrome card is installed
in the system and the MGA card has its VGA disabled.
(PCI boards only) A monochrome card will not be recognized if the MGA
has its VGA enabled. The system will boot, but the monochrome card will be
unusable (i.e. "mode mono" will do nothing).
- VESA support:
The MGAVESA driver supports VESA Super VGA Extensions version 1.2 and VESA
Display Power Management Signaling (DPMS) version 1.0. This driver is
installed in \MGA\SETUP, and can be added to your AUTOEXEC.BAT.
See the README.UTL file in \MGA\SETUP for more details about VESA support.
