   8config EDD
   9        tristate "BIOS Enhanced Disk Drive calls determine boot disk"
  10        depends on X86
  11        help
  12          Say Y or M here if you want to enable BIOS Enhanced Disk Drive
  13          Services real mode BIOS calls to determine which disk
  14          BIOS tries boot from.  This information is then exported via sysfs.
  15
  16          This option is experimental and is known to fail to boot on some
  17          obscure configurations. Most disk controller BIOS vendors do
  18          not yet implement this feature.
  19
  20config EDD_OFF
  21        bool "Sets default behavior for EDD detection to off"
  22        depends on EDD
  23        default n
  24        help
  25          Say Y if you want EDD disabled by default, even though it is compiled into the
  26          kernel. Say N if you want EDD enabled by default. EDD can be dynamically set
  27          using the kernel parameter 'edd={on|skipmbr|off}'.
  28
  29config FIRMWARE_MEMMAP
  30    bool "Add firmware-provided memory map to sysfs" if EXPERT
  31    default X86
  32    help
  33      Add the firmware-provided (unmodified) memory map to /sys/firmware/memmap.
  34      That memory map is used for example by kexec to set up parameter area
  35      for the next kernel, but can also be used for debugging purposes.
  36
  37      See also Documentation/ABI/testing/sysfs-firmware-memmap.
  38
  39config EFI_PCDP
  40        bool "Console device selection via EFI PCDP or HCDP table"
  41        depends on ACPI && EFI && IA64
  42        default y if IA64
  43        help
  44          If your firmware supplies the PCDP table, and you want to
  45          automatically use the primary console device it describes
  46          as the Linux console, say Y here.
  47
  48          If your firmware supplies the HCDP table, and you want to
  49          use the first serial port it describes as the Linux console,
  50          say Y here.  If your EFI ConOut path contains only a UART
  51          device, it will become the console automatically.  Otherwise,
  52          you must specify the "console=hcdp" kernel boot argument.
  53
  54          Neither the PCDP nor the HCDP affects naming of serial devices,
  55          so a serial console may be /dev/ttyS0, /dev/ttyS1, etc, depending
  56          on how the driver discovers devices.
  57
  58          You must also enable the appropriate drivers (serial, VGA, etc.)

  63config DELL_RBU
  64        tristate "BIOS update support for DELL systems via sysfs"
  65        depends on X86
  66        select FW_LOADER
  67        select FW_LOADER_USER_HELPER
  68        help
  69         Say m if you want to have the option of updating the BIOS for your
  70         DELL system. Note you need a Dell OpenManage or Dell Update package (DUP)
  71         supporting application to communicate with the BIOS regarding the new
  72         image for the image update to take effect.
  73         See <file:Documentation/dell_rbu.txt> for more details on the driver.
  74
  75config DCDBAS
  76        tristate "Dell Systems Management Base Driver"
  77        depends on X86
  78        help
  79          The Dell Systems Management Base Driver provides a sysfs interface
  80          for systems management software to perform System Management
  81          Interrupts (SMIs) and Host Control Actions (system power cycle or
  82          power off after OS shutdown) on certain Dell systems.
  83
  84          See <file:Documentation/dcdbas.txt> for more details on the driver
  85          and the Dell systems on which Dell systems management software makes
  86          use of this driver.
  87
  88          Say Y or M here to enable the driver for use by Dell systems
  89          management software such as Dell OpenManage.
  90
  91config DMIID
  92    bool "Export DMI identification via sysfs to userspace"
  93    depends on DMI
  94    default y
  95        help
  96          Say Y here if you want to query SMBIOS/DMI system identification
  97          information from userspace through /sys/class/dmi/id/ or if you want
  98          DMI-based module auto-loading.
  99
 100config DMI_SYSFS
 101        tristate "DMI table support in sysfs"
 102        depends on SYSFS && DMI
 103        default n
 104        help
 105          Say Y or M here to enable the exporting of the raw DMI table
 106          data via sysfs.  This is useful for consuming the data without
 107          requiring any access to /dev/mem at all.  Tables are found
 108          under /sys/firmware/dmi when this option is enabled and
 109          loaded.
 110
 111config ISCSI_IBFT_FIND
 112        bool "iSCSI Boot Firmware Table Attributes"
 113        depends on X86
 114        default n
 115        help
 116          This option enables the kernel to find the region of memory
 117          in which the ISCSI Boot Firmware Table (iBFT) resides. This
 118          is necessary for iSCSI Boot Firmware Table Attributes module to work
 119          properly.
 120
 121config ISCSI_IBFT
 122        tristate "iSCSI Boot Firmware Table Attributes module"
 123        select ISCSI_BOOT_SYSFS
 124        depends on ISCSI_IBFT_FIND && SCSI && SCSI_LOWLEVEL
 125        default n
 126        help
 127          This option enables support for detection and exposing of iSCSI
 128          Boot Firmware Table (iBFT) via sysfs to userspace. If you wish to
 129          detect iSCSI boot parameters dynamically during system boot, say Y.
 130          Otherwise, say N.
