I think that Minix may be a better option for teaching because there are
books (well, 2 editions of one book) written for this purpose. The book is
titled "Operating Systems: Design and Implementation". The author of the
first Edition is A.S. Tanenbaum and the authors of the second one are A.S.
Tanenbaum and A. S. Woodhull.
The good point is that they have been translated into Spanish (I don't know
if there is a Basque translation) The translation is called "Sistemas
Operativos: Dise�o e Implementaci�n". Both editions are published by
Prentice Hall. It's very likely that you can find copies of the 1st edition
in the library of your CS faculty. The ISBN of the 2nd edition is
970-17-0165-8
Anyway, If you are very interested in ELKS, you can find some technical
papers on the ELKS site. We (at least me!!!) would be very grateful if you
wrote some essays that help people to learn how ELKS works.
About Linux, there are some documents and books about the kernel. There is
a translation of David Rusling's "The Linux Kernel" avalaible in any mirror
of LuCAS (LinUx en CAStellano). And there is a translation of a French (or
maybe English) book, called "Porgramaci�n Linux 2.0", Editorial Gesti�n
2000, de R�my Card, Eric Dumas and Franck M�vel.
Hope this help you,
Greetings from Sevilla
