	AX = 4402h subfn 00h
	BX = file handle for device "EMMXXXX0"
	CX = 0006h (size of buffer in bytes)
	DS:DX -&gt; buffer for API entry point record (see <a href=../../it/12/15.html>#01512</a>)
		first byte must be 00h on entry
Return: CF clear if successful

Notes:	this function is supported by Microsoft EMM386.EXE v4.45+ and
	  CEMM v5.10+, and is intended for use by MS Windows as it starts up
	if no other program has hooked INT 67, an alternate installation
	  check for CEMM is testing for the string
	  "COMPAQ EXPANDED MEMORY MANAGER 386" at offset 14h in the INT 67
	  handler's segment; if present, the word at offset 12h contains the
	  offset of the API entry point
