              The MGA Millennium/Mystique OS/2 PM Display Driver
                            Version 2.00.035

Product Description
-------------------

The MGA Millennium/Mystique OS/2 PM driver supports 8-bit (256 colors), 16-bit
(64K colors), and 24- and 32-bit (16M colors) display modes under OS/2 2.11 and
3.0 (Warp), in resolutions ranging from 640 x 480 to 1800 x 1440.


Driver Installation
-------------------

To install the software, follow the procedure below:

   1. If you have previously configured OS/2 for another graphics card, then
      you should uninstall the drivers for that card.  Be sure that OS/2 will
      start up in VGA mode before installing the MGA Millennium/Mystique
      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:

      "SRCPATHINSTALL",

      where SRCPATH is the path which contains the MGA PM drivers.

      Examples:

      A:INSTALL     (if installing from a diskette with OS/2 only)
      A:OS2INSTALL (if installing from diskette with OS/2 and NT)
      D:OS2INSTALL (if installing from a CD-ROM)

      Note: if you install this driver to a Warp System, you may run

      INSTALL /U

      and everything will be installed without any further input from the
      user (primary, secondary selection, driver selection, and source
      disk/path selection).

   6. You will see a dialog box in which you can select the Primary Display.
      Choose "Matrox MGA Millennium/Mystique 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, OS/2 will restart in
Matrox default MGA resolution (640 x 480 x 16M).  You may wish to select your
monitor and/or a different resolution before shutting down.  To do this, use
the MGA Settings notebook, as explained in the next section.

Note:  If you are using Selective Install in OS/2 Warp, the MGA
Millennium/Mystique driver shows up as "Other."


Driver Configuration
--------------------

To change the driver monitor configuration or mode (resolution or pixel depth),
use the following procedure:

   1. Double-click on the MGA Settings icon on the desktop.

   2. Select the Monitor tab and either select Display Data Channel (if
      available) or choose your monitor from the list provided.

   3. Select the Resolution tab and choose the resolution/pixel depth.

You will need to reboot the system to see the change take effect.


CID Installation
----------------

Please refer to the README.CID file on the driver disk for information
concerning CID installation.



Uninstalling the Driver
-----------------------

The Matrox UNINSTAL command file makes use of the OS/2 DSPINSTL.EXE program
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 MGAOS2

      UNINSTAL
      or
      UNINSTAL CLEAN (to also delete the Matrox files from your hard disk)

   3. Once the MGA driver has been uninstalled, the DSPINSTL utility will
      launch.  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.

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 program
     in an OS/2 window or full screen session:

              SETVGA

Monitor Customization using Matrox's MGA Settings Notebook
----------------------------------------------------------

The OS/2 Millennium/Mystique driver supports VESA DDC-2B compliant monitors.

If your monitor is not detected as DDC compliant, the driver will take the
"Unknown Monitor" hardcoded timings, which assume that you have a monitor
supporting all resolutions available on 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 MGA settings
notebook.  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 MGA settings notebook is located in the System Setup folder, described
below.

You must shut down OS/2 and reboot your computer for the changes to take
effect.

Note:  The timing information in MGA.INF overrides the timing info returned by
DDC compliant monitors.  If you are using a DDC compliant monitor, and you do
not wish to override the monitor's timing info, then check the "Use Data
Display Channel (DDC)" box.


Monitor Customization using the SYSTEM icon
-------------------------------------------

Beginning with V1.20, it is possible to select the monitor refresh rate from
the OS/2 System icon.  This capability is not enabled by default.  To enable
this feature, use the /OS2REFRESH option when running INSTALL.  (In Driver
Installation Step 5 described above, type INSTALL /OS2REFRESH)

After installing the drivers using the /OS2REFRESH option, configure the
monitor refresh rate as follows:

   1. Right-click 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 go to Page 2 of Screen Settings.

   5. On Page 2, select a monitor from the "Display name" list box.

   6. Return to Page 1 of Screen Settings, and select a resolution
      and pixel depth.

   7. In the "Screen refresh rate" list box, select the desired
      monitor refresh rate rate.

After rebooting, the new refresh rate will be used.

Notes:
   - If you enable this feature and you have a DDC monitor, then
     the refresh rate you selected in the SYSTEM icon will be used
     instead of your monitor's DDC refresh rates.

   - If you wish to disable this feature, you may do so by deleting
     the SVGADATA.PMI and VIDEO.CFG files from the OS2 subdirectory.
     If these files also exist in the root directory, then you must
     delete these files as well.


Driver configuration using the MGA settings notebook
----------------------------------------------------

Advanced configuration of the MGA driver can be performed through the MGA
settings notebook, located in the System Setup folder and shadowed on the
desktop.

Fonts page:

   You may change font settings for the current resolution, and they will be
   remembered if you switch resolutions.  You may change font resolution and
   system font size using the Fonts page.  To change the default AVIO font,
   open an OS/2 or DOS Window, select Font Size from the system menu, select
   the desired font, and click the Save button.  Your selection will be stored
   when you exit the MGA settings notebook.

   Font resolution affects your desktop icon font.  The system font is used
   for window titles and menus and also affects window sizes.


   Note that the default values for the fonts are:

                System Font  Font res  AVIO Font
    640x480     Small         96        8x14
    800x600     Small         96        8x14
   1024x768     Medium       120       12x22
   1152x864     Large        120       12x22
   1280x1024    Large        120       12x22
   1600x1200    Large        120       12x22    (Millennium only)
   1600x1280    Large        120       12x22    (Millennium PowerDoc only)
   1800x1440    Large        120       12x22    (Millennium PowerDoc only)


Advanced page:

1. Grayscale driver switch

   Owners of the Millennium PowerDoc Edition may enable the grayscale driver
   switch, which defines whether 8 bits per pixel should be in 256 colors or
   256 gray shades.

2. DIVE switch

   Due to an OS/2 problem in 32 bpp, the Warp Digital Video player image
   may be shifted to the left.  24 bpp may trap under certain conditions.

   The MGA settings notebook has a switch to ensure DIVE is always enabled in
   24 and 32bpp.  Note that when the box is not checked, DIVE will still be
   used in some cases where no problems were found to occur with OS/2 FixPak
   17 installed.

3. EnDIVE switch

   If you wish to enable/disable EnDIVE support, use the EnDIVE switch.


For all changes you make with the MGA setttings notebook, except for hot key
changes, you must reboot your computer to see the changes take effect.


Driver configuration using MGACONF.CMD
--------------------------------------

1. Cursor Vsync

   The cursor may exhibit some "noise" when an application changes the color
   palette.  This switch forces to wait for a Vsync before changing the
   palette.  The drawback is a loss of speed when changing the palette.  Some
   animated application requires fast changing palette.  This switch applies
   only to 8 bpp.  The problem occurs only on the Millennium card, not the
   Mystique card.

   mgaconf v 0      (off)
   mgaconf v 1      (on)

   Default is 1.

2. Color cursor

   mgaconf c [0/1/2],

   where 0 will disable the software cursor (you will have 2 or less colors
           in the cursor)
         1 will enable the software cursor (multicolor cursor)
         2 will enable the software cursor if the cursor has 4 or more colors

   Default is 1.

KNOWN BUGS AND LIMITATIONS
--------------------------

The following bugs and limitations are present in this release of the
driver:

?When using the DSPINSTL program to reconfigure your MGA driver, the program
  states that VGA is the current driver.  This is because the DSPINSTL program
  included with OS/2 does not correctly identify the MGA Millennium or
  Mystique.

?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.

?The driver does not work with Mayo Clinic Family Health Book (Windows app.)
  in seamless Windows at 16bpp (64K colors).  If you need to run this
  application, please run it in Win-OS/2 fullscreen instead or change the
  colors to 256 or 16M.

?When switching quickly from PM desktop to full-screen Win-OS/2, the Win-OS/2
  desktop may get corrupted.  To restore the Win-OS/2 desktop, do a slow switch
  to PM Desktop and back to Win-OS/2.

?The mouse pointer may jump while panning.

?The MGA settings notebook may cause a system error if running when the system
  is shut down.  Close the notebook before shutting down.

?It is necessary to shut down all Win-OS/2 sessions prior to installing the
  driver.  Make sure the "Fast load" option in Win-OS/2 Setup (in the System
  Setup folder) is not checked, and close Win-OS/2 Setup prior to install.
  Otherwise, required Win-OS/2 files will not be copied, and install will fail.

?Using the large OS/2 system font on OS/2 2.11 causes some text in the MGA
  settings notebook to be cut off.  This is due to an OS/2 bug in the font
  spacing.
