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 the cards
are given below:
•
Vendor ID = 0xE159 (0xE159 for Rev 6.0 or above)
•
Device ID = 0x0002 (0x0001 for Rev 6.0 or above)
The sub IDs of
OME-PIO-D56/OME-PIO-D24
are given as follows:
•
Sub-vendor ID= 0x80 (0xC080 for Rev 6.0 or above)
•
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
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.
