3. I/O Control Register
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-up stage. The IDs of OME-PIO-D96 cards are given as
follows:
• Vendor ID = E159
• Device ID = 0002
The sub IDs of OME-PIO-D96 are given as follows:
• Sub-vendor ID= 80
• Sub-device ID = 01
• Sub-aux ID = 10
We provide all necessary functions as follows:
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 follows:
1. Resource-allocated information:
• wBase : BASE address mapping in this PC
• wIrq: IRQ channel number allocated in this PC
2. OME-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. Refer to Sec. 4.1 for more information.
