The PCI bus driver, which enumerates the PCI bus, removes unnecessary PCI-specific code from the OEM adaptation layer (OAL) and device drivers. To read bus address registers and interrupt information from the PCI configuration space header, use the registry information provided by the PCI bus driver instead of driver code that scans the PCI bus. To allow PCI enumeration of all PCI devices, update the registry for your OS design.
