You need an FP emulator.  DJGPP includes one such, and there is another one
contributed by a user.  The DJGPP FAQ list (available as faq101.zip from the
same place you get/got DJGPP) discusses the emulator and related issues in
question 3.4 (where it points you to the files you should download to get the
emulator) and in Chapter 11 (where it gives specific advice on how to set it
up and how to troubleshoot).  More set-up info can be found in the README.DJ
file.

Are you sure there isn't 387 on that DX?
