Is this really possible:? Sorry for be a bit unoptimist, but in the embeded space the o.s.must follow some rules that freebsd (nor linux, *bsd, windows, etc..) can't: - size: The o.s. must be minimal. Freebsd kernel, now, is a bit huge. - realtime: The o.s. must do some tasks at fixed times, this tasks can't wait for nothing. The size one can be fixed, but the realtime not. It needs a new scheleude, irq manager,...; so a great kernel rework. Also, you forget the PowerPC chips. They are in a lot of embedded devices and now freebsd has support for them (6.x). ----------------------------------------------------------------------------------------- Useful Acronymous : FAQ = Frequently 'Answered' Questions
