To open the Device Manager:
Device Manager GUI:
In Windows' Device Manager, you can manually specify the resources for a device to solve a problem with a resource conflict in which two or more devices lay claim to the same resource. A resource conflict usually appears as a yellow exclamation point next to a device's name in Device Manager. Double-clicking the device opens its Properties box, and on the Resources tab you'll find an explanation of the problem in the Conflicting Device list.
To change a device's resource assignments, clear the Use Automatic Settings check box and select different configuration from the Settings Based On drop-down list. If none of the alternate configurations resolves the conflict, you can double-click a specific resource on the Resource Type list and enter a manual setting for it.
