3.2 The Assignment of I/O Addresses
The Plug & Play BIOS will assign an appropriate I/O address to the PIO/PISO
series card. If there is only one PIO/PISO board, the board will be identified 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 in one PC
system. Details of how to locate and identify card_0 and card_1 are provided
below:
The simplest way to identify which card is card_0 is to use the wSlotBus
and wSlotDevice functions as follows:
Step 1:
Remove all PIO-D24/D56 or PEX-D24/D56 series cards from the PC.
Step 2:
Install a single PIO-D24/D56 or PEX-D24/D56 series card into the
PCI_slot1 in the PC, then run PIO_PISO.EXE and record the
wSlotBus1 and wSlotDevice1 information.
Step 3:
Remove all PIO-D24/D56 or PEX-D24/D56 series cards from the PC.
Step 4:
Install a single PIO-D24/D56 or PEX-D24/D56 series cards into the
PCI_slot2 in the PC, then run PIO_PISO.EXE and record the
wSlotBus2 and wSlotDevice2 information.
Step 5:
Repeat Steps 3 and 4 for all PCI_slots and record all wSlotBus and
wSlotDevice information.
