| If you say Y here, you are able to get EFI (Extensible Firmware | |
| Interface) variable information via sysfs. You may read, | |
| 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 Matt Domsch's website located at: | |
| <http://linux.dell.com/efibootmgr/testing/efibootmgr-0.5.0-test3.tar.gz> | |
