B PCI
The 32-bit Smartio C104 PCI Series board complies with the PCI specifications 2.1.
Hardware configuration for IRQ and I/O addresses is automatically assigned by the PCI
BIOS. Hence, you must first plug the board before installing the software driver.
Unlike ISA slots, different PCI slots in the same PC may have different bus numbers and
device numbers with respect to the PCI specifications. The same PCI board will have
different system configurations if switched to a different PCI slot, which may be called
slot-sensitive or slot-dependent. This may also apply to PCI slots in PC with different
motherboard, which may use different device number sets. For example, some use 17,
18, 19, and 20 for identifying the respective PCI slots but some use 11, 12, 13 and 14.
