Preface

8Specification Update

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.

Nomenclature

Errata are design defects or errors. Errata may cause the Pentium III 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.

Preface

Specification Update 9

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.).

Summary Tables of Changes

10 Specification Update

Summary Tables of Changes

The following table indicates the Specification Changes, Errata, Specification

Clarifications or Documentation Changes, which apply to the listed MCH steppings.

Intel intends to fix some of the errata in a future stepping of the component, and to

account for the other outstanding issues through documentation or Specification

Changes as noted. This table uses the following notations:

Codes Used in Summary Table

Stepping

X: Erratum, Specification Change or Clarification that applies

to this stepping.

(No mark) or (Blank Box): This erratum is fixed in listed stepping or specification

change does not apply to listed stepping.

Status

Doc: Document change or update that will be implemented.

PlanFix: This erratum may be fixed in a future stepping of the

product.

Fixed: This erratum has been previously fixed.

NoFix: There are no plans to fix this erratum.

Row

Shaded: This item is either new or modified from the previous

version of the document.

Each Specification Update item is prefixed with a capital letter to distinguish the

product. The key below details the letters that are used in Intel’s microprocessor
