Gives a comprehensive overview on the history and "nature" of the HMA and the non-obvious design constraints to be observed when developing resident system extensions to be loaded into the HMA. It also describes how to address these issues using stubs, backdoors, and intra-segment offset relocation, a method used by DR-DOS drivers capable of relocating into the HMA and similar to a (more sophisticated) method used as the basis for the dynamic dead code elimination in the author's FreeKEYB driver.)
