Minix1 Home Page

[M] inix is an operating system developed for educational purposes. To the user Minix looks like POSIX-compliant Unix, but on the inside it is built with a modern modular micro kernel architecture. Minix is not just a toy, it is a useful operating system. This site is a demonstration of that; it is a server running the 32-bit Intel version of Minix 2.0.2. The latest available version is 2.0.4.

Minix is open source. The Minix license changed in April 2000, and applies retroactively to all previous Minix distributions, even though they still carry the old, more restrictive license within. See the Minix license-to-use in the file LICENSE. (Translation in normal language: Redistribution allowed. Keep the Copyright notice. Don't hide the Copyright notice. Don't say we endorse what you do with it. Don't blame us if it blows up in your face.)

Minix 2.0 is available for other architectures, including Sun SPARC, and can be run under an emulator (Bochs, Qemu) or a virtualizer (VMWare, Virtual PC) on many platforms, including Unix, Linux, Microsoft Windows, and MacIntosh OS.

Older versions of Minix for other architectures, including MacIntosh, are available.

[M] inix1.hampshire.edu and minix1.bio.umass.edu anonymous ftp access has been discontinued as of February 2005 because of security concerns -- the Internet is not as friendly a place as it once was. All files that were once accessible by ftp://-type URLs should be accessible simply by changing the protocol specifier of the URL to http://. I intend to edit all affected URLs on these pages, but I may have missed some. Feedback is welcomed, please contact ASW if you find a URL that is incorrect or if you can't access any file. See the bottom of this page for e-mail information.

There is a complete and current (updated daily) directory listing of the files in the public download (formerly /ftp/pub/) area. You can browse descriptive text files about contributed programs. This is also updated daily.

Our contributed software site is experimental and is not intended to be a major software repository, the selection is small and idiosyncratic. However, the site is available to any Minix user who would like to make a preliminary distribution of work in progress. Click here for information on how to submit a contribution.

Minix1.hampshire.edu is also the home site for the Minix Networking Software that supports http, ftp, telnet, rlogin, mail, and other network applications. Some of this is experimental, and not yet available in the standard Minix distribution. The developer of most of the network software available here is Michael Temari.

The major job of upgrading Minix to version 2.0 and beyond is being done by Kees Bot (kjb@cs.vu.nl). Kees and Philip Homburg (philip@cs.vu.nl) are also the creators of Minix-vmd, an enhanced Minix for 80386 and later processors that implements virtual memory and supports X11.

[M] inix was originally developed by Andrew Tanenbaum, ast@cs.vu.nl, as a tool for teaching operating systems principles. Minix release 2.0.0 is described in detail in the text Operating Systems Design and Implementation, 2nd edition, by Tanenbaum and Woodhull, published in 1997 by Prentice-Hall. Minix 2.0.0 is included on a CD-ROM with the book. This reference is a copy of the original Prentice-Hall website created when the book was published in 1997. Since then Prentice-Hall (now a division of Pearson) has posted a new OSDI/2e website.

[BOOK COVER: Operating Systems Design and Implementation, 2nd Edition,
by Andrew S. Tanenbaum and Albert S. Woodhull] [OSDI Japanese ed.] [OSDI Portuguese ed.] [OSDI Spanish ed.] The book has been published in a number of translations, including Spanish, Portuguese, and Japanese. (I'd like to know of others -- foreign publishers don't always send courtesy copies of translated works to the original authors!)

[M] inix1 URLs referencing minix1.hampshire.edu or minix1.bio.umass.edu will work equivalently. Changes made to one site are usually mirrored on the other site almost immediately. The Hampshire site is hosted at the School of Natural Science at Hampshire College and the UMass site is located at Al's workplace in the Department of Biology, School of Natural Science and Mathematics, University of Massachusetts. Both are located in Amherst, MA, USA. Click here if you would like some technical information about minix1.hampshire.edu or minix1.bio.umass.edu.

Although Hampshire College gets internet access via the University of Massachusetts, it also has an independent connection to the Internet. So the relative effects of network congestion on the two sites are hard to predict. If you have difficulty with one, try the other. The hardware at the two sites is not identical, but the differences are probably not significant for function as a server.

Here is my wishlist page: things I would like to see added to Minix or this web page.

[5 Years Old!] To the best of our knowledge, minix1.hampshire.edu is the first and oldest web site based upon standard Minix. In April 1994 operation began as an ftp site using Michael Temari's Tnet system on Minix 1.5 on an 80286 system. In February 1996 Michael's web server was added to the site, then operating under Minix 1.7.0 on an 80386. A mirror site at turing.oit.umass.edu was added in 1998. The mirror's name was changed to minix1.bio.umass.edu in October 2001. More ...
