  6. config EDD
  7. tristate "BIOS Enhanced Disk Drive calls determine boot disk"
  8. depends on X86
  9. help
  10. Say Y or M here if you want to enable BIOS Enhanced Disk Drive
  11. Services real mode BIOS calls to determine which disk
  12. BIOS tries boot from. This information is then exported via sysfs.
  13. This option is experimental and is known to fail to boot on some
  14. obscure configurations. Most disk controller BIOS vendors do
  15. not yet implement this feature.
  16. config EDD_OFF
  17. bool "Sets default behavior for EDD detection to off"
  18. depends on EDD
  19. default n
  20. help
  21. Say Y if you want EDD disabled by default, even though it is compiled into the
  22. kernel. Say N if you want EDD enabled by default. EDD can be dynamically set
  23. using the kernel parameter 'edd={on|skipmbr|off}'.
  24. config FIRMWARE_MEMMAP
  25. bool "Add firmware-provided memory map to sysfs" if EXPERT
  26. default X86
  27. help
  28. Add the firmware-provided (unmodified) memory map to /sys/firmware/memmap.
  29. That memory map is used for example by kexec to set up parameter area
  30. for the next kernel, but can also be used for debugging purposes.
  31. See also Documentation/ABI/testing/sysfs-firmware-memmap.
  32. config EFI_PCDP
  33. bool "Console device selection via EFI PCDP or HCDP table"
  34. depends on ACPI && EFI && IA64
  35. default y if IA64
  36. help
  37. If your firmware supplies the PCDP table, and you want to
  38. automatically use the primary console device it describes
  39. as the Linux console, say Y here.
  40. If your firmware supplies the HCDP table, and you want to
  41. use the first serial port it describes as the Linux console,
  42. say Y here. If your EFI ConOut path contains only a UART
  43. device, it will become the console automatically. Otherwise,
  44. you must specify the "console=hcdp" kernel boot argument.
  45. Neither the PCDP nor the HCDP affects naming of serial devices,
  46. so a serial console may be /dev/ttyS0, /dev/ttyS1, etc, depending
  47. on how the driver discovers devices.
  48. You must also enable the appropriate drivers (serial, VGA, etc.)
  49. See DIG64_HCDPv20_042804.pdf available from

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