There have been many 'Xeon' processors before that. The first ones were the
Pentium II Xeon for Slot 2 and ran at a most impressive 400 MHz. There have
been many variants after that using Slot 2, Socket 603, Socket 604,
Socket 775, Socket 771, and probably some more socket type which I have
missed. The Slot 2 and Socket 603 models do not have 64-bit support. Some
of the Socket 604 models have 64-bit support, while I believe all the Socket
775 and Socket 771 models have 64-bit support.
See http://en.wikipedia.org/wiki/List_of_Intel_Xeon_microprocessors for what
looks like a fairly complete list of them all, which should illustrate
fairly well why it is pretty much meaningless to just say that you have
a 'Xeon' processor.
