8a7d75b0 | 2 | Bus Specific Driver Override protocol as defined in the UEFI 2.0 specification.\r |
d1f95000 | 3 | \r |
4ca9b6c4 LG |
4 | Bus drivers that have a bus specific algorithm for matching drivers to controllers are\r |
5 | required to produce this protocol for each controller. For example, a PCI Bus Driver will produce an\r | |
6 | instance of this protocol for every PCI controller that has a PCI option ROM that contains one or\r | |
7 | more UEFI drivers. The protocol instance is attached to the handle of the PCI controller.\r | |
