9.4 EFI Driver Configuration Protocol
This section provides a detailed description of the EFI_DRIVER_CONFIGURATION_
PROTOCOL. This is a protocol that allows an EFI Driver to provide the ability to set controller
specific options on a controller that the driver is managing. Unlike legacy option ROMs, the
configuration of drivers and controllers is delayed until a platform management utility chooses to
use the services of this protocol. EFI Drivers are not allowed to perform setup-like operations
outside the context of this protocol. This means that a driver is not allowed to interact with the user
outside the context of this protocol.
