It should work if you use CWSDPMI as the DPMI server (other DPMI servers 
won't work with such a small memory).  But you need to be aware that if 
your applications will need more than 300K or so memory, they will begin 
to page into the 2MB DOS file system.  If the file system is implemented 
in a slow hardware (e.g. flash memory), the programs will run very slowly 
indeed.

I'm not sure why RTOS is relevant.  I don't know if RTOS can run DPMI 
programs written for DOS.
