Special Requirements: None.                                             
                                                                        
This is a device driver that makes either a hard disk or a floppy disk  
into LIM4 expanded memory.  It is a software emulation of the 28        
function standard set forth in the Lotus/Intel/Microsoft Expanded Memory
Standard (LIM/EMS) version 4.0.  All of the EMS 4.0 functions that can  
be implemented through software are provided by VMS40, with the         
exception of the DMA functions included in the Alternate Map Register   
Set function (function 28).                                             
                                                                        
The program is backwards compatible with software written for the       
earlier LIM 3.2 standard (courtesy of Lotus, Intel & Microsoft).  It    
lets you specify which drive to use for expanded memory, and how much   
disk to reserve.                                                        
                                                                        
The trial version VMS40.240 restricts you to reserving no more than 240K
for LIM memory, while the registered version VMS40.SYS allows you to    
reserve up to 32M                                                       
                                                                        
Naturally, using disk to simulate LIM memory is somewhat slower than    
having the appropriate hardware implementation, but it is also a lot    
cheaper!  If you need to run big spreadsheets, or use Borland's         
standalone debugger to debug a really large program, and you cannot     
afford 2Meg of LIM memory, then VMS40 is your answer.
