800 | This option enables special console drivers which allow the kernel | |
801 | to print messages very early in the bootup process. | |
802 | ||
803 | This is useful for kernel debugging when your machine crashes very | |
490dcc4d RD |
804 | early before the console code is initialized. For normal operation, |
805 | it is not recommended because it looks ugly on some machines and | |
806 | doesn't cooperate with an X server. You should normally say N here, | |
