README.OS2 MATROX GRAPHICS INC. Matrox OS/2 PM Display Driver Version 2.54.130 Matrox G400 & Matrox G450 MGA Millennium/Mystique MGA-G100/MGA-G200 Product Description ------------------- This OS/2 PM driver for the Matrox G450, Matrox G400, MGA Millenium, MGA Mystique, MGA-G100 and MGA-G200 video accellerator chips supports 8-bit (256 colors), 16-bit (64K colors), and 24- and 32-bit (16M colors) display modes under OS/2 2.11 and later, in resolutions ranging from 640x480 to 2048x1536. 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 Matrox drivers. 2. Using the Command Prompts folder of OS/2, open an OS/2 Window or Full Screen session. 3. 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. 4. Make the CD-ROM or floppy disk the active drive and type: "SRCPATH\INSTALL", where SRCPATH is the path which contains the Matrox OS/2 drivers. Examples: A:\INSTALL (if installing from a diskette with OS/2 only) A:\OS2\INSTALL (if installing from diskette with OS/2 and NT) D:\OS2\INSTALL (if installing from a CD-ROM) Note: if you install this driver to a Warp System, you may run \INSTALL /U for all but Japanese OS/2 or \INSTALL /UJ for Japanese OS/2 (DBCS driver disk only) and everything will be installed without any further input from the user (primary, secondary selection, driver selection, and source disk/path selection). 5. You will see a dialog box in which you can select the Primary Display. Choose "Matrox G400/G450, Millennium/Mystique/MGA-G100/MGA-G200 Series". You may have to change the source drive if you are not installing from drive A. 6. 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 haven't previously installed a high-resolution driver, OS/2 will restart in Matrox default resolution (640x480x256). If you know which resolutions your monitor is capable of displaying, you may wish to configure the driver for your monitor and/or a different resolution before shutting down. To do this, use the MGA Settings notebook, as explained in the next section. However, if you do this before shutting down, some resolutions shown by the MGA Settings notebook may be invalid, and, if you select one of those, OS/2 will restart in a different, valid resolution instead. Note: If you are using Selective Install in OS/2 Warp, the Matrox G400/G450 Millennium/Mystique/MGA-G100/MGA-G200 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 Use 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 \MGA\OS2 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 Driver Reinstallation --------------------- To reinstall the same level Matrox driver as was previously installed, run DSPINSTL. Select the primary display as in installation step 6 above. Change the source drive to \MGA\OS2 (on your boot drive), and then press the Install button. When DSPINSTL finishes, shut down and reboot. Monitor Customization using Matrox's MGA Settings Notebook ---------------------------------------------------------- The OS/2 Matrox G400/G450 Millennium/Mystique/MGA-G100/MGA-G200 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 should change the monitor setting on the Monitor page of the notebook. If your monitor is not listed, try to choose a similar monitor or one of the standard monitors. MGA Settings then 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. 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 the system font 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. Note that this is not supported with the DBCS driver. Font resolution affects the sizes of your OS/2 fonts. The system font is the default font and also affects window sizes. On Warp 4, the WarpSans font is used for window titles and menus. On previous OS/2 versions, the window titles and menus use the default font. If you want to change this, you may drag any font from the Font Palette to any window title or menu bar while holding the Alt key. Note that the default values for the fonts are: System Font Font res AVIO Font 640x480 10.System Proportional 96 8x14 800x600 10.System Proportional 96 8x14 1024x768 10.System Proportional 120 12x22 1152x864 12.System Proportional 120 12x22 or higher 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 Warp 3 with 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. mgaconf v 0 (off) mgaconf v 1 (on) Default is 1. 2. Color cursor mgaconf c [0/1/2], where 0 will enable the software cursor (multicolor cursor) 1 will disable the software cursor (you will have 2 or fewer colors in the cursor) 2 will disable the software cursor if the cursor has fewer than 4 colors Default is 0.

This is because the DSPINSTL program included with OS/2 does not correctly identify the Matrox drivers. · 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. · 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. · Selecting a scalable font as the OS/2 system font on OS/2 2.11 and Warp 3 without a FixPak does not work correctly. A system proportional font is used instead. You can obtain a list of scalable fonts by opening the Font Palette, pressing the Edit Font button, and pressing the Delete button. In the Delete Font window, any font with file extension OFM is a scalable font. Warp 3 FixPak 17 is known to fix this problem. · Using MGA Settings to select the OS/2 system font is not supported with the DBCS driver. · When using higher than 1280x1024 resolution, if you use MGA Settings to change the monitor setting to a monitor which does not support the current resolution, you must shut down the system prior to switching to a full screen session. Otherwise, the system will hang when switching back to the desktop.

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/MGA-G100/MGA-G200 driver. 2. Using the Command Prompts folder of OS/2, open an OS/2 Window or Full Screen session. 3. 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. 4. Make the CD-ROM or floppy disk the active drive and type: "SRCPATH\INSTALL", where SRCPATH is the path which contains the Matrox OS/2 drivers. Examples: A:\INSTALL (if installing from a diskette with OS/2 only) A:\OS2\INSTALL (if installing from diskette with OS/2 and NT) D:\OS2\INSTALL (if installing from a CD-ROM) Note: if you install this driver to a Warp System, you may run \INSTALL /U for all but Japanese OS/2 or \INSTALL /UJ for Japanese OS/2 (DBCS driver disk only) and everything will be installed without any further input from the user (primary, secondary selection, driver selection, and source disk/path selection). 5. You will see a dialog box in which you can select the Primary Display. Choose "Matrox MGA Millennium/Mystique/MGA-G100/MGA-G200 Series". You may have to change the source drive if you are not installing from drive A. 6. 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 haven't previously installed a high-resolution driver, OS/2 will restart in Matrox default resolution (640x480x256). If you know which resolutions your monitor is capable of displaying, you may wish to configure the driver for your monitor and/or a different resolution before shutting down. To do this, use the MGA Settings notebook, as explained in the next section. However, if you do this before shutting down, some resolutions shown by the MGA Settings notebook may be invalid, and, if you select one of those, OS/2 will restart in a different, valid resolution instead. Note: If you are using Selective Install in OS/2 Warp, the MGA Millennium/Mystique/MGA-G100/MGA-G200 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 Use 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 \MGA\OS2 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 Driver Reinstallation --------------------- To reinstall the same level Matrox driver as was previously installed, run DSPINSTL. Select the primary display as in installation step 6 above. Change the source drive to \MGA\OS2 (on your boot drive), and then press the Install button. When DSPINSTL finishes, shut down and reboot. Monitor Customization using Matrox's MGA Settings Notebook ---------------------------------------------------------- The OS/2 Millennium/Mystique/MGA-G100/MGA-G200 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 should change the monitor setting on the Monitor page of the notebook. If your monitor is not listed, try to choose a similar monitor or one of the standard monitors. MGA Settings then 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. 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 the system font 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. Note that this is not supported with the DBCS driver. Font resolution affects the sizes of your OS/2 fonts. The system font is the default font and also affects window sizes. On Warp 4, the WarpSans font is used for window titles and menus. On previous OS/2 versions, the window titles and menus use the default font. If you want to change this, you may drag any font from the Font Palette to any window title or menu bar while holding the Alt key. Note that the default values for the fonts are: System Font Font res AVIO Font 640x480 10.System Proportional 96 8x14 800x600 10.System Proportional 96 8x14 1024x768 10.System Proportional 120 12x22 1152x864 12.System Proportional 120 12x22 or higher 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 Warp 3 with 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. mgaconf v 0 (off) mgaconf v 1 (on) Default is 1. 2. Color cursor mgaconf c [0/1/2], where 0 will enable the software cursor (multicolor cursor) 1 will disable the software cursor (you will have 2 or fewer colors in the cursor) 2 will disable the software cursor if the cursor has fewer than 4 colors Default is 0.

This is because the DSPINSTL program included with OS/2 does not correctly identify the Matrox Millennium/Mystique/MGA-G100/MGA-G200. · 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. · 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. · Selecting a scalable font as the OS/2 system font on OS/2 2.11 and Warp 3 without a FixPak does not work correctly. A system proportional font is used instead. You can obtain a list of scalable fonts by opening the Font Palette, pressing the Edit Font button, and pressing the Delete button. In the Delete Font window, any font with file extension OFM is a scalable font. Warp 3 FixPak 17 is known to fix this problem. · Using MGA Settings to select the OS/2 system font is not supported with the DBCS driver. · When using higher than 1280x1024 resolution, if you use MGA Settings to change the monitor setting to a monitor which does not support the current resolution, you must shut down the system prior to switching to a full screen session. Otherwise, the system will hang when switching back to the desktop.

README.OS2 MATROX GRAPHICS INC. 13-Mar-1996 The MGA OS/2 PM Display Driver v 2.10.020 Product Description ------------------- This MGA OS/2 PM driver supports 8-bit (256 colors), 16-bit (64K colors), and 24-bit (16M colors) display modes under OS/2 2.1 up to "Warp", in resolutions ranging from 640 x 480 to 1600 x 1200. The driver works on all MGA Ultima and Impression models. It also includes a Seamless Windows driver. Driver Installation ------------------- To install the software, follow the procedure below: 1. If you are installing this driver for the first time, have the MGA board installed and boot OS/2. Select VGA as the display 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: "SRCPATH\INSTALL", where SRCPATH is the path which contains the MGA PM drivers. Examples: A:\INSTALL (if installing from a diskette with OS/2 only) A:\OS2\INSTALL (if installing from diskette with OS/2 and NT) D:\OS2\INSTALL (if installing from a CD-ROM) 6. You will see a dialog box in which you can select the Primary Display. Choose "Matrox MGA 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, or over a version older than 2.00, OS/2 will restart in the default MGA resolution (640 x 480 x 256). It is therefore advisable to select the desired resolution immediately before rebooting, by means of the OS/2 System Setup folder, as explained in the next section. Driver Configuration -------------------- To change the driver mode (resolution or pixel depth), use the following procedure: 1. Click the right button 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 choose the resolution/pixel depth. You will need to reboot the system to see the change take effect. Uninstalling the Driver ----------------------- The OS/2 DSPINSTL.EXE program can be used 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 \OS2\INSTALL DSPINSTL 3. 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. You may want to create an icon for the OS/2 DSPINSTL program if you plan to use it frequently. 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 file in an OS/2 window or full screen session: \OS2\INSTALL\RSPDSPI.EXE Your MGA OS/2 diskette also comes with an "UNINSTAL" utility. This batch file removes lines that load the driver from your config.sys file. If used with the "CLEAN" parameter, the driver files will even be deleted from your hard drive. The batch file also invokes DSPINSTL so you can select another display driver. To use the UNINSTAL utility: 1. Open an OS/2 Text Window (or Full Screen) session 2. Enter: CD \MGA\OS2 UNINSTAL or UNINSTAL CLEAN Monitor Customization --------------------- By default, the driver assumes that you have a monitor which supports all resolutions available to 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 MGAMON program. 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 MGAMON program is located in the \MGA\OS2\ directory. It is a DOS program, so it must be run in a DOS session (either windowed or full screen). To run MGAMON, open a DOS session: 1. Enter: CD \MGA\OS2 MGAMON 2. Select a monitor and exit the program. You must shut down OS/2 and reboot your computer for the changes to take effect. Board Testing ------------- If you encounter any problems running OS/2 with your board, you should first determine whether it is a system or hardware problem. The best way to check for a potential hardware problem is to use the MGA SETUP program. SETUP is a DOS program that is included on the MGA CAD Driver disk, version 1.50 and later. It cannot be run from an OS/2 Command Prompt session. If you have a DOS (FAT) partition on your hard disk, simply install the Setup and Utilities product using the provided installation program. Then go to the \MGA\SETUP directory and type SETUP. If you do not have a DOS partition, you will have to create a bootable disk that has SETUP on it. Here is the procedure: 1. Insert the proper installation disk in your diskette drive. 2. Copy A:\SETUP\FILES1.ZIP and A:\PKUNZIP.EXE to a location on your hard disk. 3. Make that hard disk location current and type "PKUNZIP FILES1" to unarchive the files. 4. Remove the installation disk and format a new bootable DOS disk. 5. Copy the following files from your hard disk to your new floppy disk: SETUP.EXE, DOS4GW.EXE, MGA.MON 6. Reboot your computer with the the new disk. 7. Type SETUP. In SETUP, select "Graphic Mode Test" to test the various modes that are available for your board. The program will not attempt to test a mode which is not supported by your board. The default test will be done at a 60Hz refresh rate for all resolutions. If you have a customized monitor file (MGA.INF) in your \MGA\OS2 subdirectory, SETUP can read it and act upon it if you set the MGA environment variable as shown below: SET MGA=C:\MGA\OS2 Driver History -------------- 2.00A3 - 32-bit driver supporting 8, and 24 bpp color. - Added "clean" option to UNINSTAL.CMD for removing old MGA PM drivers from the hard disk.

KNOWN BUGS AND LIMITATIONS -------------------------- The following bugs and limitations are present in this release of the driver: - AT (ISA) and VL boards mapped at AC000: We don't advise that you use the (default) mapping of AC000 with this OS/2 driver. At that address, full screen Windows does not work. On some systems with a VGA on the motherboard, other modes could be unsupported, such as DOS in a window and Seamless Windows. - You will need to modify the settings of your WINOS2 Full Screen session if your board is mapped at D8000-DBFFF (The WINOS2 Full Screen driver will not be able to find the board). To fix this: 1. Open the settings of your WINOS2 full screen icon. 2. Turn to the session page. 3. Push the WINOS2 settings button. 4. Set the MEM_EXCLUDE_REGIONS to D8000-DBFFF. You should do the same for all of your Windows applications running in full screen mode. - MGA boards with BIOS revisions older than 3.40 might experience the following problems: - Opening a DOS Full Screen session results in a blank screen. - Maximizing (Alt+Home) a DOS Window results in a blank screen. - Toggling (Alt+Esc) continuously from a Win-OS/2 full screen session to the OS/2 PM results in a system hang. - Only 21 lines are displayed (EGA mode) when you type MODE CO80 from a DOS session. All of the above-stated problems can be resolved by adding the following line to the AUTOEXEC.BAT file: \MGA\OS2\FIXVGA.EXE A batch file called FIXAUTO.CMD can be used to automatically add the above line to your AUTOEXEC.BAT file, for a permanent fix. This batch file is installed in your \MGA\OS2 directory. If your MGA board has a 3.40 revision BIOS (or later), make sure NOT to use FIXVGA.EXE. The BIOS revision may be obtained by running the MGA DOS Setup program. - Dual-boot users should take note of this significant problem: When rebooting for DOS using the "DualBoot" icon of the Command Prompts folder, the system will reboot, but the MGA card will remain in a high resolution mode, and the DOS prompt will not be visible. Immediate workaround: reset your computer to go to DOS. Permanent workaround: change the behavior of the DualBoot icon to make sure that it goes to full screen mode BEFORE actually rebooting the computer. To do so, follow the procedure below: 1) Using a text editor, create a file containing the following two lines: BOOT.EXE /DOS PAUSE Save the file as (for example) BOOTDOS.CMD in your C:\MGA\OS2 directory. 2) Edit the "settings" of the dual-boot icon. - Click on the Session page. - Remove the check mark from the "Close window on exit" option. - Change the "OS/2 windows" option to "OS/2 full screen". In the "Path and filename" field enter: C:\MGA\OS2\BOOTDOS.CMD instead of the current BOOT.EXE /DOS line - The MGA OS/2 driver comes with a special keyboard driver (KBD01.SYS for OS/2 2.1 and 2.11 and KBDBASE.SYS for Warp OS/2 3.0). This special driver will detect a Ctrl+Alt+Del and reset the MGA board to a proper state before the system reboots. If you install the OS/2 2.1 Service Pack after having installed the MGA driver, the Service Pack installation program will detect a different keyboard driver and ask you if you want to replace it. PLEASE DO NOT REPLACE THE KEYBOARD DRIVER. If you accidentally replace it, simply reinstall the MGA OS/2 Driver to restore our special keyboard driver. - When using the DSPINSTL program to reconfigure your MGA driver, the program states that VGA is the current driver. This is a bug in the DSPINSTL program that is included by IBM. - DIVE is not supported in 24 bpp by default (but Multimedia Video player still works). If you want to enable 24bpp DIVE, please run: \MGA\OS2\MGACONF d 1 to enable DIVE in 24bpp. - The MMODE.EXE program included with the Setup & Utilities is not supported in a OS/2 DOS Session. - 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.
