I don't know where exactly I found this but I think it does what you want.

Its called source mapper and its from Leif-Erik Larsen.  The version I have is 
0.99E.  I think it comes with several different executable for DOS, OS2, ...

Alta-vista should be able to find a home page.  The exact executable name I use
is sm386.exe.
