Int 2F Fn 160B  - Ms Windows 3.1 - Identify Tsrs                           [W]

   AX = 160Bh
   ES:DI = 0000h:0000h

Return: ES:DI -> TSR information structure (see #2325)
Desc:  this call allows Windows-aware TSRs to make themselves known to
     Windows.

Note:  the TSR should first chain to the previous INT 2F handler, then
     allocate a communication structure, place the returned ES:DI
     pointer in the first field, and return a pointer to the new
     structure
