INT 2F - MS Windows/386 - GET INSTANCE DATA
AX = 1603h
Return: AX = 5248h ('RH') if supported
DS:SI -> Windows/386 instance data (see #02630)
Notes: reportedly supported by RM Nimbus MS-DOS 3.3 kernel
this function is called by DOSMGR when AX=1607h/BX=0015h is not
supported, as is the case in DOS versions prior to 5.0
see Geoff Chappell's book _DOS_Internals_ for additional discussions of
this function, DOSMGR's behavior, and instancing in general
