INT 67 - LIM EMSsee Expanded Memory Specification 4.0 - GET HANDLE DIRECTORY
	AH = 54h
	AL = subfunction
	    00h get handle directory
	       ES:DI -> buffer for handle directory (see #03651)
	    01h search for named handle
	       DS:SI -> 8-byte name
	    02h get total number of handles
Return: AL = number of entries in handle directory (subfunction 00h)
	DX = value of named handle (subfunction 01h)
	BX = total number of handles (subfunction 02h)
	AH = status (00h,80h,81h,84h,8Fh,A0h,A1h) (see also #03650)
	    A1h a handle found had no name


Format of EMSsee Expanded Memory Specification handle directory entry:
