Found a link for the book at: http://cw.prenhall.com/bookbind/pubbooks/tanenbaum/ Considering multiple processors depends on what the ultimate objective is. If your Kernel is aimed at some limited embedded machines, maybe one is good enough. If your Kernel aims to be a workstation/general-purpose full-blown OS when it grows up, multiple processors are going to be there & you want to leave the door open for that. Likewise for multiple computers wired together with shared resources - you're going to have networked computers and you'll want to leave the door open for that. The early design decisions have to be lived with for a very long time, so they should be taken carefully. Don't design in limitations that cripple you down the road. (Think of MS-DOS limitations and how long Microsoft was hamstrung in what they could do to remain backward compatible.)
