How do I avoid bus errors reading data from an E1563A/64A FIFO over MXI-2?

This is probably due to bus collisions and to the MXI-2 interface requesting the bus too quickly after a collision. Matrox video cards are frequently involved in this problem.

If you force viMove to use programmed I/O transfers rather than using the DMA controller, it should fix that.

Set the DisableMiteDMA value to 1 in the registry key HKEY_LOCAL_MACHINE\SOFTWARE\National Instruments\NI-VXI for WIN32. You can edit the value of that key with the Windows utility REGEDIT. Start > Run > regedt then go to the path and file shown above.

NI warns that this may adversely affect the throughput performance a little, but I observed a dramatic increase in performance.
