The Assignment of I/O Address

The Plug & Play BIOS will assign the proper I/O address to PIO/PISO
series card. If there is only one PIO/PISO board, the user can identify the
board as card_0. If there are two PIO/PISO boards in the system, it is very
difficult to identify which board is card_0. The software driver can support the
maximum 16 boards. Therefore, the user can install 16 boards of PIO/PSIO
series cards in one PC system. For how to find and identify the card_0, card_1
and the others is demonstrated as below:
The simplest way to identify which card is card_0 is to use wSlotBus
& wSlotDevice as follows:
1. Remove all PIO-D64/PIO-D64U from this PC
2. Install one
PIO_PISO.EXE and record the wSlotBus1 & wSlotDevice1
3. Remove all PIO-D64/PIO-D64U from this PC
4. Install one
PIO_PISO.EXE and record the wSlotBus2 & wSlotDevice2
5. Repeat (3) & (4) for all PCI_slot?, record all wSlotBus? & wSlotDevice?
The records may be as follows:
PC's PCI slot
Slot_1
Slot_2
Slot_3
Slot_4
PCI-BRIDGE
Slot_5
Slot_6
Slot_7
Slot_8
