9 | tristate "BIOS Enhanced Disk Drive calls determine boot disk (EXPERIMENTAL)" | |
10 | depends on EXPERIMENTAL | |
11 | depends on !IA64 | |
12 | help | |
13 | Say Y or M here if you want to enable BIOS Enhanced Disk Drive | |
14 | Services real mode BIOS calls to determine which disk | |
15 | BIOS tries boot from. This information is then exported via sysfs. | |
16 | ||
17 | This option is experimental and is known to fail to boot on some | |
18 | obscure configurations. Most disk controller BIOS vendors do | |
19 | not yet implement this feature. | |

22 | tristate "EFI Variable Support via sysfs" | |
23 | depends on EFI | |
24 | default n | |
25 | help | |
26 | If you say Y here, you are able to get EFI (Extensible Firmware | |
27 | Interface) variable information via sysfs. You may read, | |
28 | write, create, and destroy EFI variables through this interface. | |
29 | ||
30 | Note that using this driver in concert with efibootmgr requires | |
31 | at least test release version 0.5.0-test3 or later, which is | |
32 | available from Matt Domsch's website located at: | |
33 | <http://linux.dell.com/efibootmgr/testing/efibootmgr-0.5.0-test3.tar.gz> | |

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 | ||
47 | If your firmware supplies the HCDP table, and you want to | |
48 | use the first serial port it describes as the Linux console, | |
49 | say Y here. If your EFI ConOut path contains only a UART | |
50 | device, it will become the console automatically. Otherwise, | |
51 | you must specify the "console=hcdp" kernel boot argument. | |
52 | ||
53 | Neither the PCDP nor the HCDP affects naming of serial devices, | |
54 | so a serial console may be /dev/ttyS0, /dev/ttyS1, etc, depending | |
55 | on how the driver discovers devices. | |
56 | ||
57 | You must also enable the appropriate drivers (serial, VGA, etc.) | |

65 | Say m if you want to have the option of updating the BIOS for your | |
66 | DELL system. Note you need a Dell OpenManage or Dell Update package (DUP) | |
67 | supporting application to comunicate with the BIOS regarding the new | |
68 | image for the image update to take effect. | |

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