With the vast majority of PC's, you can steal an extra 64K of upper 
memory by moving the EMS page frame to E000. 

This will not work if you use emm386 just to provide umb's (ie with 
the 'noems' option); it will not work on IBM PS/2's, which have an 
extended BIOS located in the E000 segment; it may not work with some 
peripherals that use this segment.

the emm386 invocation in your config.sys file would look something 
like this :

DEVICE=C:\BIN\emm386.exe 1024 frame=E000
