  6. config EDD
  7. tristate "BIOS Enhanced Disk Drive calls determine boot disk"
  8. depends on !IA64
  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 EFI_VARS
  25. tristate "EFI Variable Support via sysfs"
  26. depends on EFI
  27. default n
  28. help
  29. If you say Y here, you are able to get EFI (Extensible Firmware
  30. Interface) variable information via sysfs. You may read,
  31. write, create, and destroy EFI variables through this interface.
  32. Note that using this driver in concert with efibootmgr requires
  33. at least test release version 0.5.0-test3 or later, which is
  34. available from Matt Domsch's website located at:
  35. <http://linux.dell.com/efibootmgr/testing/efibootmgr-0.5.0-test3.tar.gz>
  36. Subsequent efibootmgr releases may be found at:

  38. config EFI_PCDP
  39. bool "Console device selection via EFI PCDP or HCDP table"
  40. depends on ACPI && EFI && IA64
  41. default y if IA64
  42. help
  43. If your firmware supplies the PCDP table, and you want to
  44. automatically use the primary console device it describes
  45. as the Linux console, say Y here.
  46. If your firmware supplies the HCDP table, and you want to
  47. use the first serial port it describes as the Linux console,
  48. say Y here. If your EFI ConOut path contains only a UART
  49. device, it will become the console automatically. Otherwise,
  50. you must specify the "console=hcdp" kernel boot argument.
  51. Neither the PCDP nor the HCDP affects naming of serial devices,
  52. so a serial console may be /dev/ttyS0, /dev/ttyS1, etc, depending
  53. on how the driver discovers devices.
  54. You must also enable the appropriate drivers (serial, VGA, etc.)
  55. See <http://www.dig64.org/specifications/DIG64_HCDPv20_042804.pdf>
  56. config DELL_RBU
  57. tristate "BIOS update support for DELL systems via sysfs"
  58. depends on X86
  59. select FW_LOADER
  60. help
  61. Say m if you want to have the option of updating the BIOS for your
  62. DELL system. Note you need a Dell OpenManage or Dell Update package (DUP)
  63. supporting application to communicate with the BIOS regarding the new
  64. image for the image update to take effect.
  65. See <file:Documentation/dell_rbu.txt> for more details on the driver.
  66. config DCDBAS
  67. tristate "Dell Systems Management Base Driver"
  68. depends on X86
  69. help
  70. The Dell Systems Management Base Driver provides a sysfs interface
  71. for systems management software to perform System Management
  72. Interrupts (SMIs) and Host Control Actions (system power cycle or
  73. power off after OS shutdown) on certain Dell systems.
  74. See <file:Documentation/dcdbas.txt> for more details on the driver
  75. and the Dell systems on which Dell systems management software makes
  76. use of this driver.
  77. Say Y or M here to enable the driver for use by Dell systems
  78. management software such as Dell OpenManage.
  79. config DMIID
  80. bool "Export DMI identification via sysfs to userspace"
  81. depends on DMI
  82. default y
  83. help
  84. Say Y here if you want to query SMBIOS/DMI system identification
  85. information from userspace through /sys/class/dmi/id/ or if you want
  86. DMI-based module auto-loading.
  87. config ISCSI_IBFT_FIND
  88. bool "iSCSI Boot Firmware Table Attributes"
  89. depends on X86
  90. default n
  91. help
  92. This option enables the kernel to find the region of memory
  93. in which the ISCSI Boot Firmware Table (iBFT) resides. This
  94. is necessary for iSCSI Boot Firmware Table Attributes module to work
  95. properly.
  96. config ISCSI_IBFT
  97. tristate "iSCSI Boot Firmware Table Attributes module"
  98. depends on ISCSI_IBFT_FIND
  99. default n
  100. help
  101. This option enables support for detection and exposing of iSCSI
  102. Boot Firmware Table (iBFT) via sysfs to userspace. If you wish to
  103. detect iSCSI boot parameters dynamically during system boot, say Y.
  104. Otherwise, say N.
