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. |

26 | If you say Y here, you are able to get EFI (Extensible Firmware |

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.) |
