LT
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.

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}'.

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.

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.)

77 help
78 The Dell Systems Management Base Driver provides a sysfs interface
79 for systems management software to perform System Management
80 Interrupts (SMIs) and Host Control Actions (system power cycle or
81 power off after OS shutdown) on certain Dell systems.
82
83 See <file:Documentation/dcdbas.txt> for more details on the driver
84 and the Dell systems on which Dell systems management software makes
85 use of this driver.
86
87 Say Y or M here to enable the driver for use by Dell systems
88 management software such as Dell OpenManage.

105 data via sysfs. This is useful for consuming the data without
106 requiring any access to /dev/mem at all. Tables are found
107 under /sys/firmware/dmi when this option is enabled and

115 This option enables the kernel to find the region of memory
116 in which the ISCSI Boot Firmware Table (iBFT) resides. This
