26 Matrox Graphics Card – Installation Guide
3 Double-click the name of your Matrox display adapter to open a properties dialog box. The
type of problem is displayed in the
General
tab 
Device Status
area. Check also the
Resource
tab 
Resource Settings
list for an
Interrupt Request
.
 Solution – Change settings in your computer’s CMOS setup utility.
If your computer has the options of enabling Plug-and-Play detection, or assigning an IRQ
to a VGA adapter, make sure they’re enabled. If your computer doesn’t have these options,
you may be able to manually assign an IRQ to your graphics card using the CMOS setup
utility.
For more information on your computer’s CMOS setup utility, see your system manual or
contact your system manufacturer.
 Solution – Windows 95: You may have to manually assign an IRQ to your Matrox card
with the irqset program in the C:\Program Files\Matrox MGA PowerDesk folder. For
instructions on how to use irqset, see the
Start
menu 

file.
 Cause – Your computer’s other BIOS settings may be incorrect.
 Solution – Reset your computer’s BIOS settings to the factory defaults using the CMOS
setup utility. The factory defaults are usually the “safest” settings. Check your system
manual for more information.
Problem: Game for Windows 95 doesn’t start or runs slower than normal
(program uses Microsoft DirectX interface)
 Cause – An older version of DirectX may be installed. The Matrox Installation CD-ROM setup
program installs DirectX as part of the MGA PowerDesk software installation, but some
programs install an older version of DirectX (overwriting your version). To see what version of
DirectX is installed:
1 Right-click the Windows desktop background, then click the
Properties
menu item 
Information
tab.
2 Look at the
Microsoft DirectX Version
label.
If DirectX 3.0 or later is not installed, follow the instructions below.
 Solution – Install DirectX version 3.0 or later. To install DirectX 3.0:
1 Insert the Matrox CD-ROM in your CD-ROM drive. Windows automatically starts the
CD-ROM setup program; click
Cancel
to continue.
2 Click the
Start
button 
Run
menu item.
3 Type “d:\directx3\dxsetup”, where “d:\” is the drive letter of your CD-ROM drive; then
click
OK
to start the DirectX setup program.
