When installed, the Driver Family Override Protocol produces a GUID that represets
|
|
a family of drivers. Drivers with the same GUID are members of the same family
|
|
When drivers are connected to controllers, drivers with a higher revision value
|
|
in the same driver family are connected with a higher priority than drivers
|
|
with a lower revision value in the same driver family. The EFI Boot Service
|
|
Connect Controller uses five rules to build a prioritied list of drivers when
|
|
a request is made to connect a driver to a controller. The Driver Family Protocol
|
|
rule is between the Platform Specific Driver Override Protocol and above the
|
|
Bus Specific Driver Override Protocol
|
|
|

@param FamilyGuid A pointer to the GUID that represnets the family of drivers
