Inferno Operating System

Inferno was originally developed at Bell Labs (the research division of Lucent Technologies). It is a well-designed, economical operating system particularly suitable for use in networked devices such as advanced video telephones, hand-held devices, TV set-top boxes, and many other embedded applications. Inferno can run in native mode on an embedded system or in emulation mode under many different operating systems. Inferno has many features in common with Plan 9.

    Release Notes: The Inferno 3rd Edition release by Vita Nuova represents the transition of the Inferno Operating Systems from Lucent Technologies. The third edition includes new hosted operating systems support, new applications, and a variety of bugfixes. Perhaps most significantly, the 3rd Edition release is being distributed under a completely different licensing model from previous Lucent-provided distributions. Binaries (w/source code for applicaitons) for Linux, Windows, and Plan 9 are available from the Vita Nuova Web pages. Vita Nuova also offers a boxed set w/full source code, binaries, and printed documentation for all supported operating systems (Plan 9, FreeBSD, Linux, Solaris, Windows, Irix, Unixware, and HP/UX) and native hardware (x86, PowerPC, ARM, StrongARM, and MIPS).
