OZONE is an object-oriented operating system written in the C programming language. Almost everything in the kernel is an object (threads, processes, devices, files, event flags, etc) to which can be assigned logical names. On i686 based processors it uses the protection ring concept to a greater extent than the systems it was inspired by (VMS, Unix, Windows NT). As only small interrupt handlers run in kernel mode (ring 0) and what makes-up the actual kernel runs in exec mode (ring 1). www.o3on… (More on Ozone)
