PIO_DriverInit(&wBoards, wSubVendor,wSubDevice,wSubAux)

•wBoards=0 to N Æ Number of boards found in this PC

•wSubVendor Æ SubVendor ID of board to find

•wSubDevice Æ SubDevice ID of board to find

•wSubAux Æ SubAux ID of board to find

This function can detect all OME-PIO/PISO series card in the system. It is implemented based on the PCI Plug & Play mechanism. It will find all OME- PIO/PISO series cards installed in this system & save all their resources in the library.
