PCI
The 32-bit Smartio C168H/PCI 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 switching to a different PCI slot,
