Basically, protected mode allows your programs to run in a 32-bit flat
memory model, which eliminates the need for segments, far pointers, and
all the other pitfalls of real mode programming.  Grab the DJGPP
Frequently Asked Questions list (v2/faq210b.zip) and read chapters 17
and 18 for a detailed explanation of how to convert all that icky old
Borland code to the shiny new syntax of protected mode.  For an
explanation of protected mode and other DJGPP concepts, visit
<http://www.delorie.com/djgpp/doc/lexicon/> and other documents at that
site.
