Specification Update 9
Preface
This document is an update to the specifications contained in the documents listed in
the following Affected Documents/Related Documents table. It is a compilation of
device and document errata and specification clarifications and changes, and is
intended for hardware system manufacturers and for software developers of
applications, operating system, and tools.
Information types defined in the Nomenclature section of this document are
consolidated into this update document and are no longer published in other
documents. This document may also contain information that has not been previously
published.

NOTES:
1. Hyper-Threading Technology requires a computer system with an Intel®Pentium®4
processor supporting HT Technology and a Hyper-Threading Technology enabled
chipset, BIOS and operating system. Performance will vary depending on the specific
hardware and software you use. See <<http:// www.intel.com/info/hyperthreading/>>
for more information including details on which processors support HT Technology.

Nomenclature
Errata are design defects or errors. Errata may cause the Intel®Pentium®4
processor’s behavior to deviate from published specifications. Hardware and software
designed to be used with any given stepping must assume that all errata
documented for that stepping are present on all devices.
Specification Changes are modifications to the current published specifications.
These changes will be incorporated in the next release of the specifications.
Specification Clarifications describe a specification in greater detail or further
highlight a specification’s impact to a complex design situation. These clarifications
will be incorporated in the next release of the specifications.
Documentation Changes include typos, errors, or omissions from the current
published specifications. These changes will be incorporated in the next release of the
specifications.
Note: Errata remain in the specification update throughout the product’s lifecycle, or until a
particular stepping is no longer commercially available. Under these circumstances,
errata removed from the specification update are archived and available upon
request. Specification changes, specification clarifications and documentation
changes are removed from the specification update when the appropriate changes
are made to the appropriate product specification or user documentation
(datasheets, manuals, etc.).
