	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 resource information in the library.

Sample program 1: find all OME-PIO-D56/OME-PIO-D24 in the PC

wSubVendor=0x80; wSubDevice=1; wSubAux=0x40; /*	for	OME-PIO-
D56/D24 */

wRetVal=PIO_DriverInit(&wBoards, wSubVendor,wSubDevice,wSubAux); printf("Threr are %d OME-PIO-D56/OME-PIO-D24 Cards in this PC\n",wBoards);

/* step2: save resources of all OME-PIO-D56/OME-PIO-D24cards installed in

this PC */
for (i=0; i<wBoards; i++)
{
PIO_GetConfigAddressSpace(i,&wBase,&wIrq,&wID1,&wID2,&wID3,
&wID4,&wID5);
printf("\nCard_%d: wBase=%x, wIrq=%x", i,wBase,wIrq);
wConfigSpace[i][0]=wBaseAddress;	/* save all resource of this card	*/
wConfigSpace[i][1]=wIrq;	/* save all resource of this card	*/
