I agree on the 'noems' switch (or '/frame=none' for DR-DOS users).

I don't understand this as I use emm386 (well, the DR-DOS version) and
NDOS without any trouble at all. Here is my shell statement:

shell=c:\nu\ndos.com c:\nu /e:1024U /u /p

The /u tells it to put the memory resident portion into a UMB, the /e part
makes a environment area of 1024 bytes in high memory, and the fact that
I don't specify a swapping mode means it does a best guess, which in my
case means XMS swapping. I have never had a problem with NDOS and I've been
using it with several patch levels of djgpp. Perhaps you could post your 
config.sys file and we'll find out what's wrong.
