PCI

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.
