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 the cards are given below:
OME-PIO-D24
< REV 1.0 ~ REV 5.0 > :
• Vendor ID = 0xE159 (0xE159 for Rev 6.0 or above)
• Vendor ID = 0xE159
• Device ID = 0x0002 (0x0001 for Rev 6.0 or above)
• Device ID = 0x0002
• Sub-vendor ID = 0x80
• Sub-device ID = 0x01
• Sub-aux ID = 0x40
The sub IDs of
OME-PIO-D56
• Sub-vendor ID= 0x80 (0xC080 for Rev 6.0 or above)
< REV 1.0 ~ REV 4.0 > :
• Vendor ID = 0xE159
• Sub-device ID = 0x01
• Device ID = 0x0002
• Sub-aux ID
• Sub-vendor ID = 0x80
• Sub-device ID = 0x01
• Sub-aux ID = 0x40
We provide all the following necessary functions:
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. 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
