3.1 How to Find the I/O Address

The plug & play BIOS will assign a proper I/O address to every OME-PIO/PISO series card in the power-on stage. The fixed IDs of OME-PIO/PISO series cards are given as following:

• Vendor ID = 0xE159	< REV 4.0 or above > :
< REV 1.0 ~ REV 3.0 > :

•VendorDeviceID =ID0xE159= 0x0002 (0x0001• VendorforID =Rev0xE1594.0 or above)

• Device ID = 0x0002		• Device ID = 0x0001
• Sub-vendor ID = 0x80		• Sub-vendor ID = 0x5C80
The sub IDs of OME-PIO-D144are given as following:
• Sub-device ID = 0x01		• Sub-device ID = 0x01
•	Sub-Vendor ID= 0x80	(0x5C80 for Rev 4.0 or above)
• Sub-aux ID = 0x00		• Sub-aux ID = 0x00
•	Sub-Device ID = 0x01
•	Sub-Aux ID = 0x00

We provide all necessary functions as following:

1.PIO_DriverInit(&wBoard, wSubVendor, wSubDevice, wSubAux)

2.PIO_GetConfigAddressSpace(wBoardNo,*wBase,*wIrq, *wSubVendor, *wSubDevice, *wSubAux, *wSlotBus, *wSlotDevice)

3.Show_PIO_PISO(wSubVendor, wSubDevice, wSubAux)

All functions are defined in PIO.H. Refer to Chapter 4 for more information. The important driver information is given as following:

1. Resource-allocated information:

•wBase : BASE address mapping in this PC

•wIrq: IRQ channel number allocated in this PC

2. PIO/PISO identification information:

•wSubVendor: subVendor ID of this board

•wSubDevice: subDevice ID of this board

•wSubAux: subAux ID of this board

3. PC’s physical slot information:

•wSlotBus: hardware slot ID1 in this PC’s slot position

•wSlotDevice: hardware slot ID2 in this PC’s slot position

The utility program, PIO_PISO.EXE, will detect & show all OME-PIO/PISO cards installed in this PC.
