Pentium® Pro Processor-Specification Update

This document is an update to the specifications contained in the Pentium® Pro Processor Family Developer's Manuals (Order Numbers 242690, 242691 and 242692), and the Intel Architecture Software Developer's Manuals (Order Numbers 243190 and 243191). It is intended for hardware system manufacturers and software developers of applications, operating systems, or tools. It contains specification changes, S-specs, errata, specification clarifications, and documentation changes.

The Pentium Pro processor may contain design defects or errors known as errata which may cause the product to deviate from published specifications. Current characterized errata are available on request.

Specification Changes are modifications to the current published specifications. These changes will be incorporated in the next release of the specifications.
S-Specs are exceptions to the published specifications, and apply only to the units assembled under the S-spec.
Errata are design defects or errors. Errata may cause the Pentium Pro 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 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.
