	  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.
