This file declares Firmware Volume protocol.
|
|
The Firmware Volume Protocol provides file-level access to the firmware volume.E ach firmware
|
|
volume driver must produce an instance of the Firmware Volume Protocol if the firmware volume
|
|
is to be visible to the system.T he Firmware Volume Protocol also provides mechanisms for
|
|
determining and modifying some attributes of the firmware volume.
