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
