INT 15 - Phoenix 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. v4.0 - GET MEMORY SIZE FOR >64M CONFIGURATIONS (32-bit)
	AX = E881h
Return: CF clear if successful
	    EAX = extended memory between 1M and 16M, in K (max 3C00h = 15MB)
	    EBX = extended memory above 16M, in 64K blocks
	    ECX = configured memory 1M to 16M, in K
	    EDX = configured memory above 16M, in 64K blocks
	CF set on error

	this interface is used by Windows NT 3.1, OS/2 v2.11/2.20, and is
