  HIMEM.SYS is simply an extended memory manager.  That's it.  Windows need
  access to extended memory to have more room to run.  In your case, with a
  386SX, if you have 1024K of free extended RAM, you can run in Enhanced mode.
  So yes, you DO need HIMEM.SYS (or another extended memory manager).  QEMM
  is an extended memory manager that allows you to install some drivers in
  the upper memory block (area from 640k to 1 Meg).  You might look into
  one of these if you're trying to free up some conventional RAM.
