+config EDD
+ tristate "BIOS Enhanced Disk Drive calls determine boot disk"
+ depends on X86
+ 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 and is known to fail to boot on some
+ obscure configurations. Most disk controller BIOS vendors do
+ not yet implement this feature.
+
+config EDD_OFF
+ bool "Sets default behavior for EDD detection to off"
+ depends on EDD
+ default n
+ help
+ Say Y if you want EDD disabled by default, even though it is compiled into the
+ kernel. Say N if you want EDD enabled by default. EDD can be dynamically set
+ using the kernel parameter 'edd={on|skipmbr|off}'.
+
+config FIRMWARE_MEMMAP
+ bool "Add firmware-provided memory map to sysfs" if EXPERT
+ default X86
+ help
+ Add the firmware-provided (unmodified) memory map to /sys/firmware/memmap.
+ That memory map is used for example by kexec to set up parameter area
+ for the next kernel, but can also be used for debugging purposes.
+
+ See also Documentation/ABI/testing/sysfs-firmware-memmap.
+
+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>
+
+config EFI_VARS_PSTORE
+ bool "Register efivars backend for pstore"
+ depends on EFI_VARS && PSTORE
+ default y
+ help
+ Say Y here to enable use efivars as a backend to pstore. This
+ will allow writing console messages, crash dumps, or anything
+ else supported by pstore to EFI variables.
+
+config EFI_VARS_PSTORE_DEFAULT_DISABLE
+ bool "Disable using efivars as a pstore backend by default"
+ depends on EFI_VARS_PSTORE
+ default n
+ help
+ Saying Y here will disable the use of efivars as a storage
+ backend for pstore by default. This setting can be overridden
+ using the efivars module's pstore_disable parameter.
+
+config EFI_PCDP
+ bool "Console device selection via EFI PCDP or HCDP table"
+ depends on ACPI && EFI && IA64
+ default y if IA64
+ help
+ If your firmware supplies the PCDP table, and you want to
+ automatically use the primary console device it describes
+ as the Linux console, say Y here.
+
+ If your firmware supplies the HCDP table, and you want to
+ use the first serial port it describes as the Linux console,
+ say Y here. If your EFI ConOut path contains only a UART
+ device, it will become the console automatically. Otherwise,
+ you must specify the "console=hcdp" kernel boot argument.
+
+ Neither the PCDP nor the HCDP affects naming of serial devices,
+ so a serial console may be /dev/ttyS0, /dev/ttyS1, etc, depending
+ on how the driver discovers devices.
+
+ You must also enable the appropriate drivers (serial, VGA, etc.)
+
+ See DIG64_HCDPv20_042804.pdf available from
+ <http://www.dig64.org/specifications/>
+
+config DELL_RBU
+ tristate "BIOS update support for DELL systems via sysfs"
+ depends on X86
+ select FW_LOADER
+ help
+ Say m if you want to have the option of updating the BIOS for your
+ DELL system. Note you need a Dell OpenManage or Dell Update package (DUP)
+ supporting application to communicate with the BIOS regarding the new
+ image for the image update to take effect.
+ See <file:Documentation/dell_rbu.txt> for more details on the driver.
+
+config DCDBAS
+ tristate "Dell Systems Management Base Driver"
+ depends on X86
+ help
+ The Dell Systems Management Base Driver provides a sysfs interface
+ for systems management software to perform System Management
+ Interrupts (SMIs) and Host Control Actions (system power cycle or
+ power off after OS shutdown) on certain Dell systems.
+
+ See <file:Documentation/dcdbas.txt> for more details on the driver
+ and the Dell systems on which Dell systems management software makes
+ use of this driver.
+
+ Say Y or M here to enable the driver for use by Dell systems
+ management software such as Dell OpenManage.
+
+config DMIID
+ bool "Export DMI identification via sysfs to userspace"
+ depends on DMI
+ default y
+ help
+ Say Y here if you want to query SMBIOS/DMI system identification
+ information from userspace through /sys/class/dmi/id/ or if you want
+ DMI-based module auto-loading.
+
+config DMI_SYSFS
+ tristate "DMI table support in sysfs"
+ depends on SYSFS && DMI
+ default n
+ help
+ Say Y or M here to enable the exporting of the raw DMI table
+ data via sysfs. This is useful for consuming the data without
+ requiring any access to /dev/mem at all. Tables are found
+ under /sys/firmware/dmi when this option is enabled and
+ loaded.
+
+config ISCSI_IBFT_FIND
+ bool "iSCSI Boot Firmware Table Attributes"
+ depends on X86
+ default n
+ help
+ This option enables the kernel to find the region of memory
+ in which the ISCSI Boot Firmware Table (iBFT) resides. This
+ is necessary for iSCSI Boot Firmware Table Attributes module to work
+ properly.
+
+config ISCSI_IBFT
+ tristate "iSCSI Boot Firmware Table Attributes module"
+ select ISCSI_BOOT_SYSFS
+ depends on ISCSI_IBFT_FIND && SCSI && SCSI_LOWLEVEL
+ default n
+ help
+ This option enables support for detection and exposing of iSCSI
+ Boot Firmware Table (iBFT) via sysfs to userspace. If you wish to
+ detect iSCSI boot parameters dynamically during system boot, say Y.
+ Otherwise, say N.
