Matrox Graphics Card – User Guide

Solution
Change settings in your computer BIOS 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 BIOS setup
utility.
For more information on the BIOS setup utility of your computer, see your system manual
or contact your system manufacturer.
