Make sure you have the line : DOS=HIGH,UMB  in your config.sys.  Then you can
take out the  noems i=e000-efff  parameter.  Replace it with the amount of
ems you need, e.g. :

device=himem.sys
device=emm386.exe 4096
dos=high,umb
...

..will load DOS in the HMA, will make 4096K (4mb) available as ems, and will
give you access to UMBs for devicehigh and loadhigh statements.
