3.2 The Assignment of the I/O Addresses
The Plug & Play BIOS will assign an appropriate I/O address for each
PIO/PISO series card. If there is only one I/O board, the board will be identified
as card_0. However, if there are two or more I/O boards in the system,
identifying which board is card_0 becomes more difficult. The software driver
can support a maximum of 16 boards.
Sometimes, it is difficult to find the card number. The easiest way to
identify which card is card_0 is to use the wSlotBus and wSlotDevice
functions in the following manner:
Step 1:
Remove all PIO-DA4/8/16 series cards from the PC.
Step 2:
Install a PIO-DA4/8/16 series card into PCI_slot1 on the PC and then
run PIO_PISO.EXE. Record the results shown for wSlotBus1 and
wSlotDevice1.
Step 3:
Remove all PIO-DA4/8/16 series cards from the PC.
Step 4:
Install a PIO-DA4/8/16 series card into PCI_slot2 on the PC and then
run PIO_PISO.EXE again. Record the result shown for wSlotBus2 and
wSlotDevice2.
Step 5:
Repeat (3) and (4) for all PCI_slots and record the results shown for
each wSlotBus and wSlotDevice.
