- Installation
- ------------
-
- To install both MGA PowerDesk and the MGA display driver, start the
- included "setup" program.
-
- The setup program first asks you which language you want to use, then
- to choose between a "Typical" or "Custom" installation. With a
- "Typical" installation, the setup program installs all MGA PowerDesk
- utilities in the default "\Program Files\Matrox MGA PowerDesk" folder.
- We recommend you use "Typical".
-
- After PowerDesk is installed, the setup program automatically changes
- the Windows 95 display driver, then prompts you to restart your computer
- for all changes to take effect.
-
- You can customize the installation process by editing the "mga.ini"
- file. For example, you can change the default installation path, default
- driver performance switches, default schemes, and so on. The file is
- self-documented. This type of customization is for advanced users only.
-
- - More Information
- For more information on settings, refresh rates etc., see the WordPad
- file "online.doc". This file is included on the Matrox disk, and installed
- in your \Program Files\Matrox MGA PowerDesk\ folder.
-
- 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
- --------------------------------
-
- - DirectDraw, Direct3D and DirectVideo support
-
- The DirectDraw driver we provide is compatible with DirectX 2 (and
- later) and includes Direct3D support. For our DirectDraw/Direct3D
- driver to be called, and benefit from hardware acceleration,
- Microsoft DirectX 2 (or later) MUST be installed, even for programs
- originally made for DirectX 1.
-
- We provide DirectX 2 on the Matrox CD-ROM. The latest DirectX is
- available from the Microsoft Web site, and is included with many
- DirectX programs.
-
- IMPORTANT: If the DirectX setup program prompts you to replace the
- existing display drivers, click "No". Otherwise, the setup program
- installs display drivers which are not as optimized as the Matrox
- drivers and which do not support PowerDesk software.
-
- Note that depending on the origin of your Microsoft DirectX software,
- it may not include DirectVideo support. For faster playback of Indeo
- and Cinepak AVI files, you should install Microsoft DirectVideo
- support.
-
- - Matrox Bus Mastering
-
- The Matrox Mystique and Millennium II support bus mastering. Bus mastering
- is a feature that allows expansion cards to perform tasks at the same time
- as your computer's CPU. The performance of programs that take advantage of
- this feature - for example, some 3D programs - is improved with bus
- mastering.
-
- To use bus mastering, your graphics card needs an interrupt request (IRQ).
- Most computers automatically assign an IRQ to graphics cards, but some do
- not. If your graphics card hasn't been assigned an IRQ, programs that
- use Matrox bus mastering may not work properly. To test for an IRQ, start
- the MGA Diagnostic program in the MGA PowerDesk folder. (Some older
- computers may not support bus mastering at all.)
-
- - Adobe Type Manager limitation
-
- With Adobe Type Manager 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 older monitors such as the NEC 3D and many "SuperVGA" monitors
- do not support non-interlaced mode in all resolutions. The MGA display
- driver does not properly handle interlaced mode with the Windows 95
- monitor selection method. If you have one of these monitors, please
- use the MGA Monitor selection method.
-
- - DirectDraw and Automatic Power Management
-
- As stated in "Microsoft DirectX release Notes", September 30, 1995, a
- DirectDraw game may be unable to restore properly if it is suspended
- by Automatic Power Management utilities.
-
- - Installation in different language versions of Windows 95
-
- If you install software in a language different from the language of
- your operating system (for example, English software on a Japanese
- system), you may have problems with text and dialog box controls being
- cut off. This is because of differences in system fonts.
-
- - VESA modes:
-
- DOS programs running in DOS full-screen mode are handled by the
- MGA Video BIOS. The BIOS supports all standard VGA modes, AND many
- VESA VBE 1.2 and 2.0 modes:

- MGA Diagnostic program
- ----------------------
-
- Restart your computer and 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 "My Computer" on the Windows desktop background.
- (2) Click the "Properties" menu item.
- (3) Click the "Device Manager" tab.
- (4) Click the "Properties" button.
- (5) Check if the MGA display 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 (10, 11 or 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.
