The Assignment of I/O Address
The Plug&Play BIOS will assign the proper I/O address to a 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 a
maximum of 16 boards. Therefore, the user can install 16 PIO/PSIO series cards onto one PC system.
The methods used to find and identify card_0 and card_1 is demonstrated below.
The simplest way to identify which card is card_0 is to use wSlotBus and wSlotDevice in the
following manner:
Step 1:
Remove all PISO-813 series boards from the PC.
Step 2:
Install one PISO-813 series
i to the PC’s PCI_slot , ru PIO_PI“O.EXE.
Then record the wSlotBus1 and wSlotDevice1 information.
Step 3:
Remove all PISO-813 series boards from the PC.
Step 4:
Install one PISO-813 series
i to the PC’s PCI_slot a d ru PIO_PI“O.EXE.
Then record the wSlotBus2 and wSlotDevice2 information.
Step 5:
Repeat Steps(3) and (4) for every PCI_slot and record all information from wSlotBus and
wSlotDevice.
The records may look similar to the table follows:
