14 | help |
15 | Say Y or M here if you want to enable BIOS Enhanced Disk Drive | |
16 | Services real mode BIOS calls to determine which disk | |
17 | BIOS tries boot from. This information is then exported via sysfs. | |
18 | ||
19 | This option is experimental and is known to fail to boot on some | |
20 | obscure configurations. Most disk controller BIOS vendors do | |
21 | not yet implement this feature. | |

28 | Say Y if you want EDD disabled by default, even though it is compiled into the | |
29 | kernel. Say N if you want EDD enabled by default. EDD can be dynamically set | |
30 | using the kernel parameter 'edd={on|skipmbr|off}'. | |

35 | help |
36 | Add the firmware-provided (unmodified) memory map to /sys/firmware/memmap. | |
37 | That memory map is used for example by kexec to set up parameter area | |
38 | for the next kernel, but can also be used for debugging purposes. | |

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

82 | The Dell Systems Management Base Driver provides a sysfs interface | |
83 | for systems management software to perform System Management | |
84 | Interrupts (SMIs) and Host Control Actions (system power cycle or | |
85 | power off after OS shutdown) on certain Dell systems. | |
