I had this problem also. I would switch between the two cases. I used (from 
memory) these two setups:
	DEVICE=C:\DOS\EMM386.EXE 8192 NOEMS M9
because this gave me UMBs to LOADHIGH, and
	DEVICE=C:\DOS\EMM386.EXE 8192 RAM M9
to get the VCPI for emacs, but not enough space to load everything high, so 
that some software requiring more than 500K of normal memory would not load.

I tried without EMM386 and emacs came up fine, but I had no UBMs of course. 

I tried
	DEVICE=C:\DOS\EMM386.EXE RAM FRAME=NONE
and emacs came up fine, but very slowly and lots of disc access (paging out I 
suppose). I had UMBs so that some stuff was loaded high. I specified 8M for 
VCPI as before
	DEVICE=C:\DOS\EMM386.EXE 8192 RAM FRAME=NONE
and emacs came up quickly and without the unexpected disc activity.

However, I still did not have all the UMBs that NOEMS gave me in the first 
place. But, I tried
	DEVICE=C:\DOS\EMM386.EXE 8192 RAM FRAME=NONE M9
which told EMM386 to make use of the memory E000 and up. This recovers most of 
the regular memory and eliminates the need to switch between the two EMM386 
commands depending on the application.

Any comments? 

(I suppose this could be directed somewhere else, except that using djgpp and 
emacs got me into these conflicts with MSDOS. Maybe someone else here is in 
the same situation).
