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\POWERDESK HKEY_LOCAL_MACHINE\SOFTWARE\MATROX\DESKNAV HKEY_LOCAL_MACHINE\SOFTWARE\MATROX\COLOR CONTROL Notes, Problems, and Limitations -------------------------------- - Another MGA driver on the Windows 95 CD-ROM This driver is part of the Windows Driver Library (WDL). In the Adapter Type field (Display Properties dialog box Settings tab -> Change Display Type button), this driver is called Matrox MGA Millennium, while the PowerDesk one is called Matrox MGA PowerDesk. The WDL driver does not support PowerDesk. - 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 PowerDesk driver. - 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 configuration when upgrading from Windows 3.1 Take note that an old MGA.INF file created by the Windows 3.1 Monitor Selection Program is still compatible with the Windows95 driver, but will not contain any data for the 1152 X 864 resolution, forcing the Windows 95 driver to fail in 640 X 480 for that resolution. We then highly recommend that you reselect a monitor with the MGA Monitor Selection property sheet as soon as you finish installation of this software product. - 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 MGA 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 the normal Microsoft "Settings" page. This has been tested under the languages we have localized PowerDesk in. With other languages, it may not work. In this case, DO NOT USE THE MICROSOFT SETTINGS PAGE. Otherwise, you will confuse the MGA 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. - 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 MGA 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 on our BBS, WEB page and newest MGA CD-ROM. 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 type A:\SETUP.EXE (if you downloaded the upgrade and put it on diskettes), or D:\MGASETUP.EXE (if you have it on your CD-ROM). Note: ONCE THE SETUP PROCEDURE IS COMPLETE, YOU MUST REBOOT YOUR COMPUTER. - VESA modes: Your MGA 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".
