| This option enables special console drivers which allow the kernel |
| to print messages very early in the bootup process. |
| |
| This is useful for kernel debugging when your machine crashes very |
| early before the console code is initialized. For normal operation, |
| it is not recommended because it looks ugly on some machines and |
| doesn't cooperate with an X server. You should normally say N here, |
| unless you want to debug such a crash. |
