No, the regular P4 does not support mulit or dual processors. The Xeon is
the dual monitor P4 much like the MP is the dual processor Athalon. There
is, in fact, both a P3 and a P4 Xeon. There is also different flavors of
the P4 Xeon.

MP for mulit-processor = 4 plus processors  ( I don't think it is limited
to just 8)

There is also lots of new server multi -processors on their way including
the 64 bit Itanium.
All of these makes thing confusing ....It's impossible to keep up with all
the changes!
