1da177e4 LT |
10 | depends on !IA64 |
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. | |

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}'. | |

30 | tristate "EFI Variable Support via sysfs" | |
31 | depends on EFI | |
32 | default n | |
33 | help | |
34 | If you say Y here, you are able to get EFI (Extensible Firmware | |
35 | Interface) variable information via sysfs. You may read, | |
36 | write, create, and destroy EFI variables through this interface. | |
37 | ||
38 | Note that using this driver in concert with efibootmgr requires | |
39 | at least test release version 0.5.0-test3 or later, which is | |
40 | available from Matt Domsch's website located at: | |
41 | <http://linux.dell.com/efibootmgr/testing/efibootmgr-0.5.0-test3.tar.gz> | |

46 | config EFI_PCDP | |
47 | bool "Console device selection via EFI PCDP or HCDP table" | |
48 | depends on ACPI && EFI && IA64 | |
49 | default y if IA64 | |
50 | help | |
51 | If your firmware supplies the PCDP table, and you want to | |
52 | automatically use the primary console device it describes | |
53 | as the Linux console, say Y here. | |
54 | ||
55 | If your firmware supplies the HCDP table, and you want to | |
56 | use the first serial port it describes as the Linux console, | |
57 | say Y here. If your EFI ConOut path contains only a UART | |
58 | device, it will become the console automatically. Otherwise, | |
59 | you must specify the "console=hcdp" kernel boot argument. | |
60 | ||
61 | Neither the PCDP nor the HCDP affects naming of serial devices, | |
62 | so a serial console may be /dev/ttyS0, /dev/ttyS1, etc, depending | |
63 | on how the driver discovers devices. | |
64 | ||
65 | You must also enable the appropriate drivers (serial, VGA, etc.) | |
66 | ||

73 | help | |
74 | Say m if you want to have the option of updating the BIOS for your | |

90563ec4 DW |
83 | help |
84 | The Dell Systems Management Base Driver provides a sysfs interface | |
85 | for systems management software to perform System Management | |
86 | Interrupts (SMIs) and Host Control Actions (system power cycle or | |
87 | power off after OS shutdown) on certain Dell systems. | |
88 | ||
89 | See <file:Documentation/dcdbas.txt> for more details on the driver | |
90 | and the Dell systems on which Dell systems management software makes | |
91 | use of this driver. | |
92 | ||
93 | Say Y or M here to enable the driver for use by Dell systems | |
94 | management software such as Dell OpenManage. | |

101 | Say Y here if you want to query SMBIOS/DMI system identification | |

110 | This option enables the kernel to find the region of memory | |
111 | in which the ISCSI Boot Firmware Table (iBFT) resides. This | |
112 | is necessary for iSCSI Boot Firmware Table Attributes module to work | |
113 | properly. | |

120 | This option enables support for detection and exposing of iSCSI | |
121 | Boot Firmware Table (iBFT) via sysfs to userspace. If you wish to | |
122 | detect iSCSI boot parameters dynamically during system boot, say Y. | |
123 | Otherwise, say N. | |
