Reassigning Legacy Board Resources in Windows 2000

Hardware: Multifunction DAQ (MIO)

Problem: How do I change the resource settings of a Legacy Device's input/output range, interrupt, and DMA in Windows 2000?

Solution:

  1. Go to Start » Settings » Control Panel » System. Select the Hardware tab at the top of the window, and then click the Device Manager button. You will see a window like the one shown below. Double-click on "Data Acquisition Devices". You should see your device listed here.


    In the picture shown above, you will note that the AT-AO-10 device appears twice. This is normal -- Windows often displays two "copies" of ISA devices which employ multiple DMA channels (Direct Memory Access).

  2. Right-click on the device and select "Properties" from the pop-up menu, or simply click the device once to highlight it and then click the Properties button.

  3. Select the Resources tab. You will see a window like the following:


    Note that the "Conflicting device list" says there are "No conflicts" for the selected resource (in this case, Direct Memory Access).

  4. Follow the instructions below if your device is in conflict:

    1. Uncheck the box for "Use Automatic Settings." Now you will be able to select a different "Basic Configuration" setting from the drop down menu.

    2. If you still see a conflict with another device, you will have to change the resource settings (Input/Output range, Interrupt, DMA) manually. Refer to the link below for instructions on how to check for free resources in your computer. Note the resources that are available.

    3. To change the resources manually, click on each resource. For instance, click on "Interrupt" to select it, then click on "Change Settings" to make the change.

    4. This will allow you to change the resource settings. Assign a resource setting that is available in your computer.

    5. After assigning the resources manually, click "OK" to quit out of the window. Close all other applications.
