PCI

The 32-bit Smartio C168H/PCI board complies with PCI specifications 2.1. Hardware

configurations for IRQ and I/O addresses are automatically assigned by the PCI BIOS.

Hence, you must first plug the board in before installing the driver software.

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. This is
