- Notes, Problems, and Limitations
- --------------------------------
-
- - DirectDraw, Direct3D and DirectVideo support
-
- The DirectDraw driver we provide is compatible with DirectX 2 and includes
- Direct3D support. For our DirectDraw/Direct3D driver to be called, and benefit
- from hardware accelerations, Microsoft DirectX 2 MUST be installed, even
- for applications originally made for DirectX 1.
-
- For your convenience we have placed a copy of the Microsoft DirectX 2
- redistributable code on our Web site. If you are getting this driver from a
- Matrox CD-ROM, you will also find a copy of DirectX 2 on the CD.
-
- If you have a Millennium card, the DirectX 2 setup will detect it and print
- the following messages:
-
- "Setup has detected display drivers that have not been tested with
- DirectX. To get the best game performance, Setup can replace your existing
- drivers."
-
- "Replace existing display drivers with DirectX drivers?"
-
- Answer "No" to the question. Otherwise, DirectX 2 would install its
- Millennium display driver which is not as optimized and does not
- support PowerDesk.
-
- Note that the Microsoft DirectX 2 code does not include DirectVideo-enabled
- codecs. Hence for faster playback of Indeo and Cinepak AVI files, you should
- install the Microsoft DirectVideo redistributable files. This package is
- available on our Web site and on our latest CD-ROM.
-
- - Bus Mastering support under Matrox Mystique
-
- The Matrox Mystique supports bus mastering, which can accelerate 3D frame
- rate and video playback in Windows 95. A switch is available in the MGA
- Advanced Settings sheet to enable/disable bus mastering.
-
- Please take note of the following regarding bus mastering in this version:
-
- - bus mastering support is not yet implemented for video playback, hence
- performance will be the same whether the switch is on or off.
-
- - bus mastering support is however implemented in Direct3D and upcoming
- Mystique bundled games.
-
- - some early PCI systems do not properly assign an interrupt to graphics
- boards such as the Mystique. Bus mastering requires an interrupt, so
- failure to get an interrupt will result in 3D applications not using
- this performance feature.
-
- - PowerDesk MGA Settings property sheet page vs the Microsoft Settings page
-
- When selecting a vertical or horizontal desktop with the MGA Settings
- page, the Microsoft Settings page is not updated with the new desktop.
- Closing and reopening the Display Properties will refresh the Settings
- page.
-
- When selecting a new monitor in the MGA Monitor page, the Microsoft
- Settings page is not updated with the resolutions that match the monitor.
- Closing and reopening the Display Properties will refresh the available
- resolutions in the Settings page.
-
- Using the Microsoft Settings page to change from a horizontal or vertical
- desktop to a non-virtual desktop mode, may result in a different desktop than
- the expected one. Rebooting the system will fix the problem.
-
- - Media XL drivers compatibility
-
- This version of MGA PowerDesk is not compatible with the Media XL drivers
- 1.03 and earlier. If you want to use the MediaXL drivers and utilities,
- you will need to install at least version 1.10 of the Media XL drivers.
- The latest drivers are available on our Web site.
-
- - 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.
-
- - 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.
-
- - 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.
-
- - VESA modes:
-
- Your MGA Video BIOS supports DOS VESA SuperVGA applications and
- games in the following modes:

- - More Information
-
- More information is available in the WordPad file "online.doc". This
- file is included on your Matrox floppy disk, and installed in your
- \Program Files\Matrox MGA PowerDesk\ folder.
-
-
- MGA Diagnostic program
- ----------------------
-
- Close all other programs before running MGA Diagnostic.
-
- The MGA Diagnostic program tests the bus mastering feature of your system and
- if another program is using bus mastering at the same time (a 3D game for example),
- a system error may occur.
-
-
- IRQSET.EXE program
- ------------------
-
- If you have a 3D program for Windows 95 that doesn't start or stops
- running, you may be having a problem with bus mastering. The Matrox card
- needs an Interrupt Request (IRQ) number for bus mastering to work properly
- and some computers do not automatically give the Matrox card an IRQ. You
- can manually assign your Matrox card an IRQ through the IRQSET.EXE program
- we provide.
-
- First, check for an IRQ number:
-
- (1) Right-click on the "My Computer" icon on the Windows 95 desktop.
- (2) Click on the "Properties" menu item.
- (3) Click on the "Device Manager" tab.
- (4) Click on the "Properties" button.
- (5) Check if the MGA driver appears in the IRQ list.
- If it does, there is no need to manually assign an IRQ and you
- can stop here.
- IF NOT, note which IRQ number between 10 and 12 is not used and
- continue with the instructions below.
-
- To manually assign an IRQ:
-
- (1) Open your "autoexec.bat" file with the Windows 95 Notepad program.
- Your autoexec.bat file is in the root directory of your boot drive.
-
- (2) Add a line to your autoexec.bat with the path to "IRQSET",
- followed by the IRQ you want to use (the unused number you noted
- above). For example, to assign your Matrox card IRQ 10, insert the
- following line in your autoexec.bat (INCLUDING the quotation marks):
-
- "C:\Program Files\Matrox MGA PowerDesk\IRQSET" A
-
- (The path you use MIGHT be different if you have a customized
- installation of MGA PowerDesk on your computer.)
-
- The above example is for IRQ 10. To use a different IRQ, replace
- "A" with ONE of the following letters (capitalized):
-
- B (for IRQ 11)
- C (for IRQ 12)
-
- (3) Save the changes to the autoexec.bat and exit Notepad.
-
- (4) Restart your computer for the changes to take effect.
-
- For more information on bus mastering, see "Troubleshooting" in the
- Installation Guide.
