Bit(s)	Description	)
 0	DAC can be switched into 8-bit mode
 1	non-VGA controller
 2	programmed DAC with blank bit (i.e. only during blanking interval)
 3	(VBE v3.0) controller supports hardware stereoscopic signalling
 3	controller supports VBE/AF v1.0P extensions

	    =0 stereo signalling via external VESA stereo connector
	    =1 stereo signalling via VESA EVC connector
 4	(VBE/AF v1.0P) must call EnableDirectAccess to access framebuffer
