^Huh?!
Socket 479 {478 pins} ->
http://en.wikipedia.org/wiki/Socket_479
There existed three
electrically incompatible, but physically identical, versions of this socket:[1]
• for Pentium III-M (released in 2001);
• for Pentium M and Celeron M 3xx (this was the most common version of the socket, and was released in 2003); and
• a version compatible with
Socket M for Intel Core, Core 2 and
Celeron M 4xx and 5xx processors.
Trust me, I had to look-up this stuff myself
