Sometimes depending upon the device we do depend on the BIOS to do the PnP initialization. For instance, if the device does not require further initialization than the PnP bios provides then there is no need for a FreeBSD driver to do any PnP related initialization. Devices such as the GUS PnP sound card needs initialization other than what the PnP provides. What we do need is a bus independent layer for ISA, PCI and PnP devices for legacy systems. The PC world is quickly moving to PCI only systems.
