Lab-PC-1200 not responding in Win2000

Question

I was using a functioning system using a Lab-PC-1200 DAQ card and Win98 and LabView 5.1.1. I upgraded the computer to Win2000, and now I am having problems.
When I first run my application, everything seems fine (I read my analog inputs from the card correctly), but when I run a portion of the application that involves data collection in a While Loop, I get an "Error -10452 @ AI Single Scan. NI-DAQ LV: No inerrupt level is available for use."
After a while of trying to troubleshoot that problem unsuccessfully, I try to go into M&A Explorer and Test Resources and get "The device is not responding to the selected base address." I was not getting this error before.
So my first goal is to find out why the device is no longer re
sponding. I am running NI-DAQ 6.9.3. In the Win2000 device manager, it says everything is operating correctly. I have tried rebooting, reseating the card, deleting the device then rebooting to re-install the drivers, and nothing seems to work.
I have read through several other complaints of similar problems, but no solutions yet. Any other ideas out there?

Hello,
I was able to find a document which is similar to your problem, although a different operating system. It sounds like for your case, you have an IRQ assigned, so that will differ from the information that I found. Regardless, I will post it for information that could assist you. I suggest checking the resources and seeing if there is anything else that is sharing your resources. If there are, either assign a different IRQ (if available) to your device, or disable the devices that are sharing. The other suggestion that I have for you is to try the device in a different computer to see if you can isolate the problem to either the board or the computer. If it is the board, then you can send the device in for a repair.
Good luck.

================================
The following trick was used on a Windows98 machine to assign an IRQ to a Lab-PC-1200 board (AT-interface) when no free IRQs were available. The lack of free IRQs caused an error -10452 during any buffered acquisition. In this case, we deliberately created a resource conflict with LPT1 and the DAQ Card, both using IRQ 7, to get the DAQ card working. The "trick" is to know that the user cannot simultaneously use LPT1 and the DAQ card and live with the conflict. Before trying this procedure, confirm that the DAQ card installed properly, and the only problem is the lack of an IRQ assignment to the card because none are available.
1) In Win9x, enter start >> settings >> control panel >> system >> device manager >> select "computer" >> properties >> select "View Resources" and IRQ. Browse the list and determine if any free IRQ levels are available - also determine what resources which are currently used are not needed. (*note : do not mess with any entries that you do not understand). In this case, the user identified LPT1 as a used resource that he would not need. Press "cancel" to get back to the device manager tab.
2) In the system control panel device manager, select the DAQ card lacking an IRQ resource under "Data Acquisition Devices". Select "properties" and go to the resources tab. Uncheck "Use Automatic Settings" and select a configuration that allows entry of an IRQ. Select IRQ and press "Change Setting", scroll through the list of IRQs until you select one used by a device that you know you can live without. In this case, we selected IRQ 7 for LPT1. (note - you can also try reserving IRQ resources under the "reserve resources" tab).
3) Reboot the computer.
4) Enter Device Manager again - observe that the two devices are now showing a conflict on the selected IRQ - this is normal and on-purpose.
5) Enter Measurement and Automation Explorer (MAX). Select the DAQ card and test resources. The device should now pass the test.
Other Suggestion:
In the BIOS, some computers allow you to select PCI only, ISA only, or both PCI/ISA for various slots, and thus reserves resources for those slots. You may be able to enter the BIOS and select "Both PCI/ISA" to free resources for use with ISA cards if they are reserved for PCI cards.
