INT 10 - VIDEO - GET CURRENT VIDEO MODE                                         
	AH = 0Fh
Return: AH = number of character columns
	AL = display mode (see #00010 at AH=00h)
	BH = active page (see AH=05h)
Notes:	if mode was set with bit 7 set ("no blanking"), the returned mode will
	  also have bit 7 set

	  (monochrome) in all extended-row text modes
	HP 200LX returns AL=07h (monochrome) if mode was set to AL=21h
	  and always 80 resp. 40 columns in all text modes regardless of
	  current zoom setting (see AH=D0h)
	when using a Hercules Graphics Card, additional checks are necessary:
	    mode 05h: if WORD 0040h:0063h is 03B4h, may be in graphics page 1
		  (as set by DOSSHELL and other Microsoft software)
	    mode 06h: if WORD 0040h:0063h is 03B4h, may be in graphics page 0
		  (as set by DOSSHELL and other Microsoft software)
	    mode 07h: if BYTE 0040h:0065h bit 1 is set, Hercules card is in
		  graphics mode, with bit 7 indicating the page (mode set by
		  Hercules driver for Borland Turbo C)
	the Tandy 2000 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. is only documented as returning AL, not AH or BH
