3.1How 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:

< REVVendor1.0 ~ REVID3=.0 >E159:

VendorDeviceID =ID0xE159= 0002

• Device ID = 0x0002

Sub-vendor ID = 0x80

The sub IDs of OME-PIO-D96

Sub-device ID = 0x01

Sub-vendor ID= 80

Sub-aux ID = 0x10

Sub-device ID = 01

Sub-aux ID = 10

<REV 4.0 or above > :

Vendor ID = 0xE159

Device ID = 0x0001

Sub-vendor ID = 0x5880 are given as follows:

Sub-device ID = 0x01

Sub-aux ID = 0x10

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.
