- If you say Y here, you are able to get EFI (Extensible Firmware

- write, create, and destroy EFI variables through this interface.
- Note that using this driver in concert with efibootmgr requires
- at least test release version 0.5.0-test3 or later, which is
- available from:
- <http://linux.dell.com/efibootmgr/testing/efibootmgr-0.5.0-test3.tar.gz>
