INT 2F U - MS-DOS 7 kernel - GET/SET ??? HANDLER                                
	AX = 160Fh
	BL = subfunction
	    00h get ??? handler
		Return: AX = 0000h if supported
			    CX:DX -> handler to which control is passed after
				      ??? executes
			   = 160Fh inside a Windows 95B DOS box
	    01h set ??? handler
		CX:DX -> new handler for ???
		Return: AX = 0000h if supported
Notes:	this function is not supported if ??? in the IO.SYS drivers portion of
	  the kernel is an IRET instruction (as is the case on my system)
	  rather than a FAR JMP
	the indicated handler seems to be related to INT 10 processing
