INT 10 - Chips & Technologies Extended 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. - AUTO EMULATION CONTROL
	AX = 5F02h
	BL = new state of autmatic emulation (00h enabled, 01h disabled)
Return: AL = 5Fh if function supported
	    AH = status
		00h unsuccessful
		01h successful
