I have the 2nd edition of that book from 2001 for an OS class I took 
spring quarter.  It seems to be an okay primer for beginners.  Some of 
it is redundant for any of us who have actually bothered to install an 
OS other than MS.  It does explain some of what an OS does and general 
explanations of scheduling, memory management, security, etc.  As a tool 
for understanding FreeBSD, it'll probably just get you familiar with the 
terminology used.

Later,
