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.

25 Say Y if you want EDD disabled by default, even though it is compiled into the

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.

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.)
