1da177e4 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. | |

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. | |

40 | tristate "EFI Variable Support via sysfs" | |
41 | depends on EFI | |
42 | default n | |
43 | help | |
44 | If you say Y here, you are able to get EFI (Extensible Firmware | |
45 | Interface) variable information via sysfs. You may read, | |
46 | write, create, and destroy EFI variables through this interface. | |
47 | ||
48 | Note that using this driver in concert with efibootmgr requires | |
49 | at least test release version 0.5.0-test3 or later, which is | |
50 | available from Matt Domsch's website located at: | |
51 | <http://linux.dell.com/efibootmgr/testing/efibootmgr-0.5.0-test3.tar.gz> | |

56 | config EFI_PCDP | |
57 | bool "Console device selection via EFI PCDP or HCDP table" | |
58 | depends on ACPI && EFI && IA64 | |
59 | default y if IA64 | |
60 | help | |
61 | If your firmware supplies the PCDP table, and you want to | |
62 | automatically use the primary console device it describes | |
63 | as the Linux console, say Y here. | |
64 | ||
65 | If your firmware supplies the HCDP table, and you want to | |
66 | use the first serial port it describes as the Linux console, | |
67 | say Y here. If your EFI ConOut path contains only a UART | |
68 | device, it will become the console automatically. Otherwise, | |
69 | you must specify the "console=hcdp" kernel boot argument. | |
70 | ||
71 | Neither the PCDP nor the HCDP affects naming of serial devices, | |
72 | so a serial console may be /dev/ttyS0, /dev/ttyS1, etc, depending | |
73 | on how the driver discovers devices. | |
74 | ||
75 | You must also enable the appropriate drivers (serial, VGA, etc.) | |

84 | Say m if you want to have the option of updating the BIOS for your | |

90563ec4 DW |
93 | help |
94 | The Dell Systems Management Base Driver provides a sysfs interface | |
95 | for systems management software to perform System Management | |
96 | Interrupts (SMIs) and Host Control Actions (system power cycle or | |
97 | power off after OS shutdown) on certain Dell systems. | |
98 | ||
99 | See <file:Documentation/dcdbas.txt> for more details on the driver | |
100 | and the Dell systems on which Dell systems management software makes | |
101 | use of this driver. | |
102 | ||
103 | Say Y or M here to enable the driver for use by Dell systems | |
104 | management software such as Dell OpenManage. | |
