LIM-EMS means Lotus Intel Microsoft Expanded Memory Specification... originally
developed to provide an expanded memory scheme that would work on all DOS
machines.  In general (if not specifically) it involves hardware paging of
memory on an LIM EMS board into a hole in ROM above A000:0000.  The current
revision of this standard is 4.0.  Extended memory involves the address range
that is available using the 286 (and up) in protected mode.  The BIOS on most
(if not all) AT class machines has routines to move data to and from memory
above 1Meg.  I won't speak on EEMS because I don't know what it is.

Pharlap is a vendor that supplies DOS extender software that allows programs
to run in protected mode on a 386.  They also have compilers and assemblers
that generate protected mode 386 code to take advantage of their DOS
extender.
