Hello Jonathas,
"(PT-BR) Se você precisar eu posso te mandar esta resposta em Português"
In this group I have seen people asking in English. I think it is better because all members can read and understand your question. So you can get more response.
The Minix was created by Andrew S. Tanenbaum in educational purpose. You can see more in:
In the link you will see the book Operating Systems: Design and Implementation 3/e that is the main documentation for version 3 of Minix . Another book is Modern Operating Systems (3rd Edition) [Andrew S. Tanenbaum] that tells about Minix too.
Here in Brazil you can buy the portuguese version of the books in (Amazon[br], Submarino, Saraiva, Casas Bahia, others).
Regards,
