);
Parameters
This A pointer to the EFI_PLATFORM_DRIVER_OVERRIDE_
PROTOCOL instance.
ControllerHandle The device handle of a controller. This must match the
controller handle that was used in a prior call to
GetDriver()
to retrieve DriverImagePath .
DriverImagePath A pointer to the driver device path that was returned in a prior
call to
GetDriverPath() .
DriverImageHandle The driver image handle that was returned by LoadImage()
when the driver specified by DriverImagePath was loaded
into memory.
Description
This function associates the image handle specified by DriverImageHandle with the device
path of a driver specified by DriverImagePath . DriverImagePath must be a value that
was returned on a prior call to GetDriverPath() for the controller specified by
ControllerHandle . Once this association has been established, then the service
GetDriver() must return DriverImageHandle as one of the override drivers for the
controller specified by ControllerHandle .
