You can view this file with WordPad. The installation process can be customized by modifying the "mga.ini" file on the diskette. Examples of customization options include: default installation path, default driver performance switches, default schemes, etc. The file is self-documented. This type of customization should be carried out by advanced users only. Registry Settings ----------------- PowerDesk settings are kept in the Windows 95 registry, under the keys: HKEY_LOCAL_MACHINE\SOFTWARE\MATROX\MILLENNIUM and HKEY_LOCAL_MACHINE\SOFTWARE\MATROX\QUICKACCESS Notes, Problems, and Limitations -------------------------------- - Another MGA Millennium driver Another MGA Millennium driver is included in the Windows Driver Library (WDL). The WDL Millennium driver does not have, or support, the PowerDesk enhancements. In the "Adapter Type" list, the WDL Millennium driver is called the "Matrox MGA Millennium", while the PowerDesk one is called "Matrox MGA Millennium PowerDesk". If you have the CD-ROM version of Windows 95, this library is included in the \Drivers\Display directory. WDL is also accessible from CompuServe and other means. See the Windows 95 "display.txt" file for more details. - Windows 95 "display.txt" file Windows 95 comes with a readme file called "display.txt" containing valuable information related to display adapters. Note that the remarks about the Matrox MGA adapters refer to the Microsoft MGA Ultima/Impression driver, not to your MGA Millennium adapter. - Adobe Type Manager limitation When Adobe Type Manager is installed, you cannot run the driver if the "Advanced Graphics Acceleration Settings" is set to none. Note that ATM is installed as part of Adobe Acrobat Reader. This is an Adobe problem documented in the Windows 95 "display.txt" file. - Monitor Refresh rates with a virtual desktop When working with a virtual desktop, the refresh rate used for the Windows 95 monitor will be derived from the virtual desktop resolution ("Desktop area") rather than from the display resolution ("Display area"). This typically will result in an inferior refresh rate, and if the virtual desktop resolution is not supported by your monitor (e.g. 1600 X 1200), the default refresh rate of only 60 Hz will be used. This limitation does not occur when using the Matrox MGA Monitor Program, where the refresh rates are taken from the display resolution. - Matrox Monitor Program and 1152 X 864 Take note that an old MGA.INF file created by the Windows 3.1 Monitor Program will not contain any data for the 1152 X 864 resolution, forcing the Windows 95 driver to work at the default 60 Hz refresh. Refresh rates equal or close to the earlier 1152 X 882 resolution are available in the new MGA.MON file. You can "refresh" your MGA.INF file by simply reselecting the same monitor you had and save it. In 1152 X 864, the Monitor Program will not immediately perform its Test Pattern with the proper timings. Please first save the "new" MGA.INF file and reboot your system before relying on the Test Pattern in 1152 X 864. - Monitors in interlaced mode Some old monitors such as the IBM 8514 and the NEC 3D do not support non- interlaced mode in all resolutions. The Millennium driver does not properly handle interlaced mode under the Windows 95 monitor mechanism, so if you own one of these monitors, please use the MGA Monitor Program. - PowerDesk and localized versions of Windows 95 When PowerDesk installs its special settings page in the Windows 95 Display Properties panel, it should grey-out most of the normal Microsoft "Settings" page. If you have Windows 95 in a language that we do not support in PowerDesk (English, French, German, Italian, and Spanish), this will not work correctly and the "Settings" page will NOT be greyed-out. If you are in that situation, DO NOT USE THE MICROSOFT SETTINGS PAGE. Otherwise, you will confuse the Millennium display driver, which uses the Windows 95 "Desktop area" as its VIRTUAL desktop area; rather than changing your resolution, you will actually change your virtual desktop. - Replacing DDC timings by MGA Monitor Program timings If you elect to use the MGA Monitor Program to override your DDC-compliant monitor, please take note of the following limitation: DO NOT USE THE "TEST" FACILITY UNTIL YOU REBOOT WINDOWS 95 WITH A SELECTED MONITOR. This means that you should be careful in selecting your monitor; if your monitor is not directly supported in the list, take no chance and pick "Multi-freq up to 1280 X 1024 @60Hz". After rebooting, you will be in safe position to pick a better match and test the various resolutions with our "Test" facility before confirming a new selection for good. - DirectDraw and Automatic Power Management As stated in "Microsoft DirectX release Notes" dated September 30, 1995, A DirectDraw game might be unable to restore properly if it is suspended by Automatic Power Management utilities. - Video acceleration under Windows 95 Microsoft DirectX is supported in this release of the Millennium driver, including DirectVideo, which provides faster Video for Windows playback with programs such as Media Player. For an application to use DirectX, a number of support files are required. These files include DirectDraw system components, DirectVideo system components, and updated Indeo and Cinepak codecs. In order to facilitate installation and setup of DirectX, Matrox has provided a DirectX upgrade package along with setup program that may be obtained from our BBS or WEB page. Even if you already have DirectVideo and DirectDraw installed on your system, we recommend you run the setup program included in the DirectX upgrade provided by Matrox in order to update the various codecs. The MGA DirectDraw driver has been optimized for the best possible video playback which requires the Indeo 3.2 codec version 3.24.15.03 and the Cinepak codec version 1.10.0.6 which are both found on the above mentioned DirectX upgrade. To start the installation of the DirectX upgrade, use the RUN function from the START menu and select A:\SETUP.EXE via the BROWSE option. If your floppy drive is not A: simply substitute A: for the drive letter of your floppy. Once you have selected the file, click on OK and the setup procedure will start. Note: ONCE THE SETUP PROCEDURE IS COMPLETE, YOU MUST REBOOT YOUR COMPUTER. - MultiMedia Superpack CD-ROM Some applications provided with your Matrox CD-ROM may not work properly (or not as fast) under Windows 95. Check on our BBS and CompuServe for updates. - Repaint problems with PanLOCK We have noted erratic window repainting problems with the PanLOCK feature. The problem is related to Windows main message queue, and happens more easily with the "window dragging" feature of the Win95 Plus Pack. It has been seen so far in Lotus 4, Access and AMIPro. There is no workaround other than to avoid using PanLOCK. - VESA modes: Your MGA Millennium Video BIOS supports DOS VESA SuperVGA applications and games in the following modes: Graphics Modes Mode Resolution Colors 100h 640x400 256 101h 640x480 256 110h 640x480 32K 111h 640x480 64K 112h 640x480 16.8M 102h 800x600 16 103h 800x600 256 113h 800x600 32K 114h 800x600 64K 115h 800x600 16.8M 105h 1024x768 256 116h 1024x768 32K 117h 1024x768 64K 118h 1024x768 16.8M(*) 107h 1280x1024 256 119h 1280X1024 32K(*) 11Ah 1280X1024 64K(*) (*) requires 4Mb memory Text Modes Mode Columns Rows 108h 80 60 109h 132 25 10Bh 132 50 10Ch 132 60 - More Information More information is available in the WordPad file "online.doc".
