Good Operating systems book?

[Jorge Mario G. Mazo]

Hi there
I want to learn about operating system to later start
contributing to FreeBSD
I would like to hear what books are good for newbies
like me!
NOTE: my C skills are pretty decent

At a local library thre is a copy of Modern Operating
System by Andrew tanebaum, but it`s the old edtion
(from 1989 I think) so I'm not sure if that would
still be valid!!!
thanks in advance
