+ 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 on some machines ugly and
+ oesn't cooperate with an X server. You should normally N here,
+ unless you want to debug such a crash.
