buffered data aquisition with an PC based RT system

[Bert]

Hello,

I've a PC system running as RT target under Labview. The communication to the host works fine. Two PCI cards are running in the target
1) a PCI CAN/2
2) a PCI MIO-16XE10

The problem is that single point data aquisition with the PCI MIO is doing. However, any trial to do bufferd aquisition failed no matter what driver version (traditional DAQ 74 or DAQmx 74) was used. This problem have become already visible while trying to create a DAQ task in the MAX. The test of a single point DAQ was OK, continuous aquisition always fails with an error message:
error -50202 occured at 'task' DAQ assistant.

In contrast, the PCI MIO board is working fine in the host computer.

Please help (otherwise I get fired 🙂

As only Single Point aqcuisition worked, it turned out to be an issue with DMA transfer between MIO card and the PC.
The problem turned out to disapper after plug and play was disabled in BIOS.
