Ian,
	Interrupt 10h reports the current video adapter.  Before the interrupt
is called the AH register gets set to 0Fh.  The interrupt stores the screen
width in AH, the video mode in AL, and the video page number in BH.  The video
mode is then determined through examination of AL.  The following numbers show
the video type for each value:  CGA = 1..6
				EGA = 13..16
                                Mono = 7
Hope that is of some help.
