Flags: callout or callback (usually hooked rather than called)

INT 2F - DOS 5+ TASK SWITCHER - IDENTIFY INSTANCE DATA

	AX = 4B05h
	ES:BX = 0000h:0000h
	CX:DX -> task switcher entry point (see #02819)
Return: ES:BX -> startup info structure (see #02822) or 0000h:0000h
Notes:	called by task switcher
	clients with instance data should hook this call, pass it through to
	  the previous handler with unchanged registers using a simulated
	  interrupt.  On return, the client should create a startup info
	  structure (see #02822), store the returned ES:BX in the "next"
	  field, and return the address of the created structure in ES:BX
	all MS-DOS function calls are available from within this call
	this function is supported by Novell DOS 7 DOSKEY, with structure v3.00
