Windows 3.x and Windows for Workgroups 3.1x in limited capabilities by forcing Windows to use Standard Mode; i.e. using 80286 Protected Mode, not 80386 Enhanced Mode. Three conditions are required:
382:
None of the FreeDOS memory managers (HIMEMX.EXE, JEMM386.EXE, JEMMEX.EXE) implement the GEMMIS API and
Windows fails to start when running in conjunction with JEMMxxx since Windows fails to take over the memory management role.

Note that
Windows in standard mode is limited in functionality, it lacks virtual memory, it skips the section in SYSTEM.INI and any device drivers in are not loaded.
