Bus Specific Driver Override protocol as defined in the UEFI 2.0 specification.
|
|
|
|
Bus drivers that have a bus specific algorithm for matching drivers to controllers are
|
|
required to produce this protocol for each controller. For example, a PCI Bus Driver will produce an
|
|
instance of this protocol for every PCI controller that has a PCI option ROM that contains one or
|
|
more UEFI drivers. The protocol instance is attached to the handle of the PCI controller.
