Right, but it doesn't really have the run-time characteristics of a full Unix system either. It is very useful for quite a few things needing very stable and fast performance near "real-time". An OS for hard real-time applications? Have a look at RTEMS 4.0 (http://www.oarcorp.com). You'll find FreeBSD code in the networking support. We've also been using BTX/BootForth for starting RTEMS applications. BootForth seems like it will be useful for diagnostic routines, while having PicoBSD in flash as an alternate boot offers useful possibilities for remote maintenance and updating. All three together are a win for our x86-based embedded computing needs. Of course, FreeBSD is an excellent development host and operations support system for all of this :-) Cheers, Jerry Hicks wghicks@bellsouth.net > > Peter > > -- > Peter Dufault (dufault@hda.com) Realtime development, Machine control, > HD Associates, Inc.
