Common problems and solutions 39
• There is a conflict in the BIOS Setup program. This problem generally occurs
when there is a PCI memory mapping error or when there is a PCI-IRQ routing
error. To resolve this problem with the PCI form factor, first try to swap boards
from one PCI slot to another.
If the above solution does not work, try the following to determine if there is an
IRQ conflict.
-Under Windows NT, go to the 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.
!Not enough memory to allocate buffer under WindowsNT 4.0
This is the message that you will receive if you try to allocate a grab buffer that is
greater than the amount of DMA memory specified during software installation.
This problem can be addressed by changing the amount of DMA memory on
your computer. Re-allocate DMA memory using the included milconfig.exe utility.
Alternatively, uninstall and reinstall MIL and specify the appropriate amount of
DMA memory.
Grabbing Problems
!The trigger pulse is not being sent
This happens when the opto-isolated trigger pulse is not connected. When using
the opto-isolated trigger, both OPTOTRIG- and OPTOTRIG+ signals must be
connected. OPTOTRIG- is usually connected to the ground of the trigger source.
