I bought this book to fulfill my desire of knowing how does an
OS work and what happens under the hood. I am happy to say
this book served the purpose extremely well. In addition, now I better understand all the necessary details of IA-64 architecture. This book not only answers 'how is it done' but also gives a precise 'why' to every 'how'. Right from the
print quality to the content everything is just wonderful. I
still enjoy repeatedly reading the Virtual Memory chapter.

I cannot explain to you what is the joy of getting all your
questions answered, to get all your doubts cleared! Nothing
short of enlightenment!! I hope to contribute to OpenSource
with my newly acquired knowledge in any way possible - This
book is certainly an inspiration.
