| 44 | If your firmware supplies the PCDP table, and you want to |

| 48 | If your firmware supplies the HCDP table, and you want to |

| 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.) |
