- BPB - BIOS Parameter Block is in the first sector of a FAT file system.
- The BPB contains information about the FAT file system. The BPB is

-
- This function retrieves the user readable name of the controller specified by

- driver specified by This has a user readable name in the language specified by
- Language, then a pointer to the controller name is returned in ControllerName,
- and EFI_SUCCESS is returned. If the driver specified by This is not currently

- support the language specified by Language, then EFI_UNSUPPORTED is returned.
-
- @param This[in] A pointer to the EFI_COMPONENT_NAME2_PROTOCOL or

-
- @param ControllerHandle[in] The handle of a controller that the driver
- specified by This is managing. This handle
- specifies the controller whose name is to be

- array indicating the language. This is the
- language of the driver name that the caller is
- requesting, and it must match one of the
- languages specified in SupportedLanguages. The
- number of languages supported by a driver is up
- to the driver writer. Language is specified in
- RFC 4646 or ISO 639-2 language code format.
-
- @param ControllerName[out] A pointer to the Unicode string to return.
- This Unicode string is the name of the
- controller specified by ControllerHandle and
- ChildHandle in the language specified by
- Language from the point of view of the driver
- specified by This.
-
- @retval EFI_SUCCESS The Unicode string for the user readable name in
