MINIX 3.3.0 is Available Now

I can't wait, take me to the download page right now.

In 2008, the European Research Council awarded Prof. Andrew S. Tanenbaum, the designer of MINIX, an Advanced Grant of €2.5 million (about $3.2 million) to produce a reliable operating system. He and his team have been working on it hard since then and they are now proud to release the result as a free and open-source operating system for the PC and ARM. It comes with a BSD license, meaning that individuals and companies can use it in products without paying royalties and without being required to disclose any changes they make to competitors.

MINIX 1 was originally a system aimed at teaching operating systems but after the ERC grant, the focus changed to include producing a solid, commercially viable product as well. The new version, MINIX 3.3.0, has a number of key features:

  • The system is based on a tiny (12,700 lines of code) microkernel
  • The microkernel handles interrupts and message passing and is the only code running in kernel mode.
  • The rest of the operating system runs as a collection of isolated, protected, user-mode processes
  • Each device driver is a separate user-mode process isolated by the MMU hardware
  • If a driver crashes, the system automatically restarts it, with running applications not even noticing
  • This means that MINIX 3.3.0 is self-healing
  • Userland is largely compatible with NetBSD and runs thousands of NetBSD packages
  • By combining an innovative self-healing research OS with NetBSD userland, we got the best of both worlds
  • Both the clang/LLVM and gcc compilers are available, as well as perl, python, etc.
  • MINIX 3.3.0 is available for both the x86 and ARM Cortex A8 architectures, making it ideal for embedded systems
  • Tools for cross compiling MINIX 3 for the ARM on Linux are provided
  • Ports are available now for the BeagleBoard XM, BeagleBone white, and BeagleBone black
  • Extensive documentation is available in the MINIX 3 wiki
  • The code has been improved over MINIX 3.2.1 in hundreds of ways, leading to a cleaner and more reliable system
  • Other features are listed here.
