Cautionary Note

The reader should keep in mind that MindShare's book series often details rapidly evolving technologies, as is the case with PCI Express. This being the case, it should be recognized that the book is a "snapshot" of the state of the technology at the time the book was completed. We make every attempt to produce our books on a timely basis, but the next revision of the specification is not introduced in time to make necessary changes. This PCI Express book complies with revision 1.0a of the PCI Express™ Base Specification released and trademarked by the PCI Special Interest Group. Several expansion card form-factor specifications are planned for PCI Express, but only the Electromechanical specification, revision 1.0 was released when this book was completed. However, the chapter covering the Card Electromechanical topic reviews several form-factors that were under development at the time of writing.
