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.

Parameters
SetOptions Allows the use to set drivers specific configuration options for a
controller that the driver is currently managing. See the
SetOptions() function description.
OptionsValid Tests to see if a controller’s current configuration options are
valid. See the
OptionsValid() function description.
ForceDefaults Forces a driver to set the default configuration options for a
controller. See the
ForceDefaults() function description.
SupportedLanguages A Null-terminated ASCII string that contains one or more
ISO 639-2 language codes. This is the list of language codes
that this protocol supports.
