        Digital's Optimized Alpha-only Windows NT Driver for 
        Matrox Millennium and Millennium II Graphics Options 

                Release Date:  5/5/97
                Release Version: V2.0

Please read this document prior to installing the Display Driver.

This document describes the Windows NT Display Driver for
Matrox Millennium and Millennium II for Digital's Alpha platforms.  

1. This Display Driver has been optimized for Alpha Platforms.  
   You will see performance gains in running both OpenGL
   clients and 2D applications over the Matrox Display Driver that
   ships as a part of Microsoft Windows NT V4.0 Release. In addition,
   this Display Driver supports the new Matrox Millennium II and
   Multi Head displays.

3. System Requirements

        Base Platform:          Alpha-only (This driver will NOT work on
                                            Intel platforms)

        OS Version:             Microsoft Windows NT V4.0
                                                  NT V4.0 SP1
                                                  

4. Installation

   To install the driver, please perform the following steps:
	
      - Log in as an administrator or as a user who has administrative 
        privilege to change the display settings.
      - Start the "Display" applet by right-clicking "Desktop" and selecting 
        "Properties". A window titled "Display Properties" will appear.
      - Click the "Settings" tab.  This lists display configurations, like 
        "Color Palette", "Font Size", and so on.
      - Press the "Display Type" button.  A new window titled "Display Type" 
        will appear.
      - Press the "Change..." button in this window.  A new window titled 
        "Change Display" will appear.
      - Press the "Have Disk..." button in this window.  A window titled 
        "Install from Disk" will appear.
      - Specify the path(Net or floppy) where the unzipped files are and 
        press "OK".  The "Change Display" window will appear with two 
        sub-windows.  Press "OK".
      - Then follow the instructions and quit the control panel applet.  
        When asked if you want to restart the machine press "Yes"(or "No" 
        to delay shutdown).  The new settings will take effect at next 
        reboot.
      - After reboot, you can select the right resolution suitable for your 
        needs.

5. Optional Tuning Applet

   The optional tuning applet ("amga_set.dll") is provided to help 
   you tune your display driver. However, we strongly recommend 
   that you choose the system defaults. The optional tuning applet 
   is integrated into the Display Properties in the Desktop.

   - To start the optional tuning applet: Right-click on the "Desktop" 
     and select Properties. A window titled "Display Properties" 
     will appear on the Desktop. Click on the "AMGA" tab. The options
     displayed are a part of the optional tuning applet. The 
     three different settings are described below.
   
   a) Enable Software Polling - (Default: Disable)
      Disabling software polling of the hardware FIFO results in improved
      performance. However, this may cause side effects if any other PCI
      devices are present on the system. We have obsevered none so far
      on any of our Alpha Platforms. 

      The above setting is valid for both Millennium and Millennium II.

   b) Enable Fast Alternate Lines - (Default: Enable)
      Enabling Fast Alternate Lines results in better line performance 
      but it trades off the compliance with Windows NT conventions.

      The above setting is valid for both Millennium and Millennium II.

   c) Enable Direct Memory Access (DMA) - (Default: Enable)
      Enabling DMA may result in better 3D performance. 2D primitives
      do not use DMA.

      This setting is valid only for Millennium II. It has no effect on 
      Millennium.     

   Once you have chosen the settings:

   - Select the "OK" button to confirm your selection.  A new dialog
     box will ask if you would like to reboot.
   - Select "Yes" to restart your machine. The new setting will only
     take effect on the next reboot.
    
6. Problems and Feedback

   If the driver fails to load, please do the following:   

      - Start the "Event Viewer" from "Administrative Tools" group 
        which can be found in "Programs" group after clicking "Start" 
        button.  A window will appear, titled "Event Viewer".
      - Select "System" from "Log" menu to view your system log.
      - Double-Click the event named "amga" under "Source" column.  
        It will bring up the "Event Detail" window. 
      - Please report the relevant information via problem reporting 
	mechanism.

7. Limitations

   OpenGL optimizations are supported in the following configurations only:

   - 4MB and 8MB Millennium boards under 15bpp(32768 Colors), 
     16bpp (65536 Colors), and 32bpp (True Color) color modes only. 
   - 4MB Millennium II boards under 15bpp (32768 Colors),
     16bpp (65536 Colors), and 32bpp (True Color) color modes only.

   * bpp = bits per pixel
