Assignment of I/O Addresses
The Plug & Play BIOS will assign proper I/O addresses to each FRB series
card during the power-up stage. If there is only one FRB board, the user can
identify the board as card_0. If there are two FRB boards in the system, the
user will find it 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
FRB 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
& wSlotDevice in the following manner:
1. Remove all FRB Series boards from the PC.
2. Install one FRB Series board into the PC
PCI_slot1, run PIO_PISO.EXE.
Then record the wSlotBus1 and wSlotDevice1 information.
3. Remove all FRB Series boards from the PC.
4. Install one FRB Series board into the PC
PCI_slot2 and run
PIO_PISO.EXE. Then record the wSlotBus2 and wSlotDevice2 information.
5. Repeat steps (3) & (4) for every PCI_slot and record all the information from
wSlotBus and wSlotDevice.
The records may look similar to the table below:
