Chapter 4 (d) - Changes MemMaker makes to th SYSTEM.INI File. 
 
MemMaker changes the Windows SYSTEM.INI file only if you are running Windows 3.0, and only if 
certain options are selected prior to memory optimization. If MemMaker does change the file, it saves 
the original file as SYSTEM.UMB.

The following list shows the changes MemMaker might make to the Windows 3.0 SYSTEM.INI file:
  
SYSTEMROMBREAKPOINT=FALSE
EMMEXCLUDE=A000-FFFF
EMMINCLUDE=<any w= regions>
DUALDISPLAY=TRUE                     if b000-b7ff is included
NOEMMDRIVER=TRUE                   if NOEMS is specified
