Query: Average book on OS

The book focus on Operating Systems and includes source code of a mini OS called Minix. Till I read it, I always read rave reviews, but found it to be quite over rated. The pros of the book includes the source for reference, a Micro kernel OS design, while what is not really upto the mark is the language tends to be difficult thereby making a tough subject even more tougher, the author's view tends to spill over and are juvenile with cliches like all students are trying to hack systems, etc and does not cover various aspects of OS subsystems.My recomendation would be the book by Abraham Silberschatz, Peter Baer Galvin called "Operating System Concepts" incase of you are starting off or just want a very easy to read book or consider various approaches.
