COLOR.4TH(8)		  BSD System Manager's Manual		  COLOR.4TH(8)

NAME
     color.4th -- FreeBSD color-detection boot module

DESCRIPTION
     The file that goes	by the name of color.4th is a set of commands designed
     to	simplify color logic.  The commands of color.4th by themselves are not
     enough for	most uses.  Please refer to the	examples below for the most
     common situations,	and to loader(8) for additional	commands.

     Before using any of the commands provided in color.4th, it	must be	in-
     cluded through the	command:

	   include color.4th

     This line is present in /boot/loader.4th file, so it is not needed	(and
     should not	be re-issued) in a normal setup.

     The commands provided by it are:

	   loader_color?	  Returns FALSE	if the loader_color environ-
				  ment variable	is set to "NO" (case-insensi-
				  tive)	or "0".	 Otherwise returns TRUE
				  (unless booting serial).

     The environment variables that effect its behavior	are:

	   loader_color
		     If	set to "NO" (case-insensitive) or "0", causes
		     loader_color? to return FALSE, indicating to many modules
		     that color	should not be used.

FILES
     /boot/loader      The loader(8).
     /boot/color.4th   color.4th itself.
     /boot/loader.rc   loader(8) bootstrapping script.

EXAMPLES
     Standard i386 /boot/loader.rc:

     Use color where applicable:

	   loader_color="YES"

SEE ALSO
     loader.conf(5), loader(8),	loader.4th(8)
