The original OS X code base does come from next but apple has upgraded the code in 10.3 to use FreeBSD 5.0 code. apple.com/macosx even mentioned that when panther was released. Another document on apple's site i'm looking for again specified that the latest 10.3 kernel was in fact using only the messaging and memory architecture of Mach and the rest was in fact FreeBSD 5.0 code! http://developer.apple.com/darwin/history.html Lucas Holt Luke@FoolishGames.com ________________________________________________________ FoolishGames.com (Jewel Fan Site) JustJournal.com (Free blogging) 'Re-implementing what I designed in 1979 is not interesting to me personally.
