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 sysfs.
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:
