Protected mode is a mode in Intel processors that demolishes the 1 MB DOS memory barrier, allows arrays larger than 64K, and protects the memory of one process from the memory of another process (provided the OS's memory manager can handle it). Read more about it in the DJGPP FAQ list, section 17.3: http://www.delorie.com/djgpp/v2faq/faq17_3.html Most protected mode programs for DOS are written to an API called DOS Protected Mode Interface, which needs a DPMI server such as CWSDPMI or Windows's. -- Damian Yerrick http://yerricde.tripod.com/ Comment on story ideas: http://home1.gte.net/frodo/quickjot.html AOL is sucks!
