   AX = 1684h

Call VSGLX16.386 entry point with:
   DX = function number
       0000h get azt16 version

       Return: CF clear

       0001h get ???
       AX = ??? (always fails if nonzero)
       ES:BX -> buffer for ???
           first DWORD of buffer must be set to length of buffer
             (in bytes, 1 <= size <= 92) before calling
