9 | If you say Y here, you are able to get EFI (Extensible Firmware | |
10 | Interface) variable information via sysfs. You may read, | |
11 | write, create, and destroy EFI variables through this interface. | |

13 | Note that using this driver in concert with efibootmgr requires | |
14 | at least test release version 0.5.0-test3 or later, which is | |
15 | available from Matt Domsch's website located at: | |
16 | <http://linux.dell.com/efibootmgr/testing/efibootmgr-0.5.0-test3.tar.gz> | |
