My understanding is that the normal DOS support in OS/2 2.0 consists
of real mode stubs lifted from DOS 5.0 that call protected mode OS/2
services; i.e., OS/2 does *emulate* DOS.  However, you do have an
option to boot real DOS in a virtual machine, which is a different
matter entirely.

Best regards,
