Please read the DJGPP Frequently Asked Questions List (faq201b.zip), 
section 10.2, for an answer to this _very_ frequently asked question.  :)

It describes why you cannot, in protected mode, simply access any ol' 
memory location without using near or far pointers.  (Also note that 
'far' pointers under protected mode mean something different than far 
pointers in 16-bit compilers like Borland.)
