Why do you have to worry about DPMI to achieve that?  Just malloc any 
amount of memory you need and read the files into the allocated buffers.  
DJGPP lets you use all the physical memory you have, and up to 128MB of 
virtual memory on top of that, and you never need to worry about all the 
DPMI stuff that goes on under the hood.

You need CWSDPMI unless you run in the environment that already has DPMI 
server installed (such as Windows which has a built-in DPMI server).

Being a beginner, please consider reading the file `readme.1st' (in the 
v2 directory at the same place where you got DJGPP) and the DJGPP FAQ 
list (v2/faq201b.zip).  They'll probably answer many your questions 
before you even ask them.
