the 32-bit smartio cp-168u boards comply with pci specifications 2.1. hardware configuration for irq and i/o addresses is automatically assigned by the pci bios. hence, you must first plug in 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 moved to a different pci slot. this is called slot-sensitive or slot-dependent, and may apply to pci slots in pcs with different motherboards, which might use different device number sets. for example, some use 17, 18, 19, and 20 for identifying the respective pci slots, whereas some use 11, 12, 13 and 14.

    due to this slot-dependency, it is necessary to re-configure the software driver once the board is plugged into a different pci slot.

    up to 4 smartio cp-168u boards can be installed in one system. when installing more than one board, remember the order of boards to distinguish the installed boards.
