Subject:      Remote boot image grabs a chunk of memory, help!

I have been trying to create a new boot image that will give my users
use of EMS. Here is my config.sys:

device=himem.sys
device=emm386.exe i=b000-b7ff x=d800-dbff x=dc00-dfff ram
 /y=s:\apps\win31\emm386.exe  <--- continuation of previous line
devicehigh=ansi.sys
shell=command.com /p /e:1024
files=60
buffers=60
dos=high,umb

This is what memory looks like when booting off the boot disk:

Now when I DOSGEN the bootdisk, and boot off the file server, this is
what memory looks like:

Why does MSDOS use more memory?

Here is my batch file that autoexec loads...

I'm using 2.15c netware and DOS 5 on a PS/2 55sx with 4 megs ram and
a IBM microchannel ethernet card.


Any ideas?
