There is two ways for you to utilize the 1M-640K as RAM:

1) Install a LIM (Lotus-Intel-MicroSoft) board. This allows DOS to access
   memory above 640K by a remapping of addresses by an algorithm called
   the LIM standard. PC Magazine has several ads discounting such boards.
   This algorithm is sometimes called the EMS (Expanded Memory Simulator).
   In order for it to be useful, a software product (like Kedit) must
   support EMS memory. Most products by Lotus and MicroSoft do. But
   the board does not allow general programs to address more than 640K.

2) There is a software product that will effect 1) above, called
   EMSimulator. This is available for $50. from:

   There is an evaluation copy of EMSIM here that you could come and
   copy. It's good for 1M; the production version is good for 8M if
   you have that much real storage. The disadvantages of the software
   product are that it takes 70K below the 640K line to run; it is
   software so it will use CPU (not that noticable on a PS/2 50 using
   Kedit); and there are conflicts using a RAM disk (VDISK.SYS) and
   EMSIM together - i.e. directories and files get randomly changed.
