  I have wondered about this FRAME=NONE.  What do you lose by doing 
this?  Can EMM386 use XMS to store the page frame in this case?  I use 
Lightning/CD disk caching software (which works great with DJGPP) and it 
could use some more upper memory.  With EMM386 it ends up having to put 
part of itself in low mem (40k).
