# # For a description of the syntax of this configuration file, # see Documentation/kbuild/kconfig-language.txt. # menu "Firmware Drivers" config EDD tristate "BIOS Enhanced Disk Drive calls determine boot disk (EXPERIMENTAL)" depends on EXPERIMENTAL depends on !IA64 help Say Y or M here if you want to enable BIOS Enhanced Disk Drive Services real mode BIOS calls to determine which disk BIOS tries boot from. This information is then exported via driverfs. This option is experimental, but believed to be safe, and most disk controller BIOS vendors do not yet implement this feature. config EFI_VARS tristate "EFI Variable Support via sysfs" depends on EFI default n help 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 Subsequent efibootmgr releases may be found at: http://linux.dell.com/efibootmgr endmenu
