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.
