40 Appendix A: Troubleshooting
!IRQ conflicts
In general, PCI devices can share an interrupt line (IRQ). However, sometimes
this might not be possible. One type of difficulty that you might run into is as
follows:
• IRQ conflict under Windows NT 4.0
In the event that your Matrox Imaging board(s) cannot share an IRQ line with
other devices, allocate a different IRQ to each device in the IRQ Configuration
Setup section of the BIOS Setup Program (accessible on bootup), if possible.
• IRQ conflict under Windows 2000
To resolve this problem, re-assign a different IRQ line to the PCI slot in which
the Matrox Meteor-II board is installed.
"Note that PCI devices cannot share interrupt lines with EISA or ISA devices.
Other possible solutions to the above problem:
• Move the Matrox Meteor-II board to another (free) PCI slot.
• Swap Matrox Meteor-II with another board, by switching PCI slots.
Problems during application development
!Computer `hangs' or produces unwanted results while an application is running
Sometimes, an EISA or ISA device might attempt to use the same interrupt,
registers, or memory space as PCI boards, and this causes a conflict. Check for an
interrupt, memory, or register conflict:
• Under Windows NT, go to Windows NT Diagnostics property page (found
under Start Programs Administrative Tools (Common). Under the Resources
page, check for devices that are sharing an IRQ with your Matrox frame grabber.
• Under Windows 2000, right-click on My Computer, and select Manage from the
presented menu. From the Computer Management explorer window, display the
System Tools\ System Information\ Hardware Resources\ IRQs folder. Check for
devices that are sharing an IRQ with your Matrox frame grabber.
