3.2 The Assignment of I/O Address
The plug & play BIOS will assign the proper I/O address to the OME- PIO/PISO series card. If there is only one
The simplest way to identify which card is card_0 is to use wSlotBus & wSlotDevice as follows :
1.Remove all
2.Install one
3.Remove all
4.Install one
5.Repeat (3) & (4) for all PCI_slot?, record all wSlotBus? & wSlotDevice?
The records may be as follows:
PC’s PCI slot | wSlotBus | wSlotDevice |
Slot_1 | 0 | 0x07 |
Slot_2 | 0 | 0x08 |
Slot_3 | 0 | 0x09 |
Slot_4 | 0 | 0x0A |
|
|
|
Slot_5 | 1 | 0x0A |
Slot_6 | 1 | 0x08 |
Slot_7 | 1 | 0x09 |
Slot_8 | 1 | 0x07 |
The above procedure will record all wSlotBus? & wSlotDevice? in this PC. These values will be mapped to this PC’s physical slot. This mapping will not be changed for any PIO/PISO cards. So it can be used to identify the specified
Step 1: Record all wSlotBus? & wSlotDevice?
Step2: Use PIO_GetConfigAddressSpace(…) to get the specified card’s wSlotBus & wSlotDevice
Step3: The user can identify the specified
