Currently, if your PCI card is not from National Instruments, you will not be able to configure it with the LabVIEW motion control tools. Usually, driver development for non-NI boards needs to be done by the manufacturer of the board because it often requires low-level knowledge of the board. The "freeware" you mentioned might be the hundreds or GPIB instrument drivers that you can download but these are for GPIB instruments. Usually, for non-NI PCI boards, you have to go to the manufacturer of the board to get the LabVIEW drivers. Hope that helps.
