To Avoid Confusion...

Over the years since the introduction of the Xeon processor, Intel® documentation always refers to any particular version of the Xeon as “the Xeon” processor. This may seem like a no brainer, but it's confusing. As an example, an Intel® document may state “this feature was introduced in the Xeon processor”. This does not clearly define which version of the Xeon processor first introduced the feature. It could have been the Pentium® II, Pentium® III, or Pentium® 4 version of the Xeon processor.

When necessary to avoid confusion, this book will state which version (Pentium® II, Pentium® III, or Pentium® 4 version) of the Xeon is being referred to.
