INT 15 U - AMIAmerican Megatrends, Inc.(American Megatrends, Inc.) A hardware, software and firmware company founded in 1985. PCI 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. - GET/SET ???
	AX = DA14h
	CL = subfunction
	    00h read
	    01h write
		DH = new value for ??? (00h-02h)
	DL = index of ??? (00h-03h, but not range-checked)
	???
Return: CF clear if successful
	    DH = current value of ??? if reading
	CF set on error
	    AH = error code (86h unsupported subfunction)
Note:	the values for indexes 00h and 01h are stored in CMOS RAMA small amount (typically 64 or 128 bytes) of memory in the system's real-time clock chip that is preserved by the clock's battery and is used for storing configuration information.  See also Real-Time Clock. location 19h,
	  and the values for 02h and 03h are stored in location 36h
BUG:	the v1.00.05.AX1 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. range-checks DH on subfunction 00h instead of
	  subfunction 01h, even though DH is never used by subfunction 00h
