Do PCI devices require a configuration file?

A PCI device is self-identifying, and hence does not require a configuration file. At boot time, the system identifies the device and its driver by reading the configuration parameters from its configuration space. However if you need to supply driver private properties, they are specified in a configuration file. See driver.conf(4) and pci(4) for more information.
