Matrox Electronic Systems 10760-101-0200 Not enough memory to allocate buffer under Windows NT

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 Windows NT 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.

!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.
