INT 10 u - VIDEO - Tseng ET-4000 BIOS(Basic Input/Output System) A set of standardized calls giving low-level access to the hardware.  The BIOS is the lowest software layer above the actual hardware and serves to insulate programs (and operating systems) which use it from the details of accessing the hardware directly. - CHECK IF HiColor MODE/SET HiColor MODE
	AX = 10F2h
	BL = function
	    00h get current HiColor mode
	    01h set 15-bit HiColor mode
	    02h set 16-bit HiColor mode
Return: AX = 0010h if supported
	    BL = video mode type
		00h not in HiColor mode
		01h 15-bit RGB(Red-Green-Blue) The color specification mechanism normally used in computer displays, where colors are separated into their primary-color components.  See also YUV. mode
		02h 16-bit RGB(Red-Green-Blue) The color specification mechanism normally used in computer displays, where colors are separated into their primary-color components.  See also YUV. mode
		03h 24-bit RGB(Red-Green-Blue) The color specification mechanism normally used in computer displays, where colors are separated into their primary-color components.  See also YUV. mode
Desc:	determine whether the display is in a graphics mode with 15 or more
	  bits per pixel color resolution
Note:	set (BL=01h/02h) only works if already in a HiColor mode
