	  If unsure, say Y.

config VT_CKO
	hex "Colored kernel message output"
	range 0x00 0xFF
	depends on VT_CONSOLE
	default 0x17
	---help---
	This option will give you ability to change the color of
	kernel messages.

	The value you need to enter here is the ASCII color value
	composed (OR'ed) by one foreground color, one background
	color and any number of attributes as follows:

	Foreground:     Background:    Attributes:
	0x01 blue       0x10 blue      0x08 highlight foreground
	0x02 green      0x20 green     0x80 blinking foreground
	0x03 cyan       0x30 cyan
	0x04 red        0x40 red
	0x05 magenta    0x50 red
	0x06 brown      0x60 brown
	0x07 gray       0x70 gray

	Thus, 0x17 will yield gray-on-blue like you can see in
	OpenBSD, 0x02 the green-on-black like on NetBSD.
	Using "highlight foreground" does not work when you use
	VGA Console and fonts with 512 glyphs.
	VGA Framebuffer is not affected.

config HW_CONSOLE
	bool
	depends on VT && !S390 && !UML
