Hmm... EMS was introduced in the XT machines - it was memory supplied on 
separate add-on extension cards and then driven by a software. The EMS 
present on i386+ machines is just an emulation of the hardware. 286 machines 
allow HMA where the EMS page may be kept.
==================================================
Stand straight, look me in the eye and say goodbye
Stand straight, we drifted past the point of

Yesterday starts tommorow, tommorow starts today
And the problems seem to be we're picking up the
  pieces of a ricochet...
