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

  57. select FW_LOADER_USER_HELPER
  58. help
  59. Say m if you want to have the option of updating the BIOS for your
  60. DELL system. Note you need a Dell OpenManage or Dell Update package (DUP)
  61. supporting application to communicate with the BIOS regarding the new
  62. image for the image update to take effect.
  63. See <file:Documentation/dell_rbu.txt> for more details on the driver.
  64. config DCDBAS
  65. tristate "Dell Systems Management Base Driver"
  66. depends on X86
  67. help
  68. The Dell Systems Management Base Driver provides a sysfs interface
  69. for systems management software to perform System Management
  70. Interrupts (SMIs) and Host Control Actions (system power cycle or
  71. power off after OS shutdown) on certain Dell systems.
  72. See <file:Documentation/dcdbas.txt> for more details on the driver
  73. and the Dell systems on which Dell systems management software makes
  74. use of this driver.
  75. Say Y or M here to enable the driver for use by Dell systems
  76. management software such as Dell OpenManage.
  77. config DMIID
  78. bool "Export DMI identification via sysfs to userspace"
  79. depends on DMI
  80. default y
  81. help
  82. Say Y here if you want to query SMBIOS/DMI system identification
  83. information from userspace through /sys/class/dmi/id/ or if you want
  84. DMI-based module auto-loading.
  85. config DMI_SYSFS

  88. default n
  89. help
  90. Say Y or M here to enable the exporting of the raw DMI table
  91. data via sysfs. This is useful for consuming the data without
  92. requiring any access to /dev/mem at all. Tables are found
  93. under /sys/firmware/dmi when this option is enabled and
  94. loaded.

  99. depends on X86 && ACPI
  100. default n
  101. help
  102. This option enables the kernel to find the region of memory
  103. in which the ISCSI Boot Firmware Table (iBFT) resides. This
  104. is necessary for iSCSI Boot Firmware Table Attributes module to work
  105. properly.

  112. This option enables support for detection and exposing of iSCSI
  113. Boot Firmware Table (iBFT) via sysfs to userspace. If you wish to
  114. detect iSCSI boot parameters dynamically during system boot, say Y.
  115. Otherwise, say N.
