Specification Update for IntelDesktop Boards Using the Intel845G Chipset

PREFACE

This document is an update to the specifications contained in the Technical Product Specification for Intel

Desktop Boards using the 845G Chipset (Order number A81229). It is intended for hardware system

manufacturers and software developers of applications, operating systems, or tools. It will contain

Specification Changes, Errata, Specification Clarifications, and Documentation Changes.

Refer to the Intel

Pentium4 Processor Specification Update (Order number 249199) for specification

updates concerning the Intel Pentium 4 processor and that may apply to the IntelDesktop Board 845GL

chipset family. Unless otherwise noted in this document, it should be assumed that any processor errata for

a given stepping are applicable to the Altered Assembly (AA) revision(s) associated with that stepping.

Refer to the Intel

845G/845GL/845GV Chipset Specification Update (Order Number 298657) for

specification updates concerning the 82845G MCH Controller and that may apply to the IntelDesktop Board

845G chipset family. Unless otherwise noted in this document, it should be assumed that any MCH errata for

a given stepping are applicable to the Altered Assembly (AA) revision(s) associated with that stepping.

Refer to the Intel

82801DB I/O Controller Hub 4 (ICH4) Specification Update (Order Number 290745) for

specification updates concerning the 82801 I/O Controller Hub and that may apply to the IntelDesktop

Board 845GL chipset family. Unless otherwise noted in this document, it should be assumed that any

82801DB I/O Controller Hub (ICH) errata for a given stepping are applicable to the Altered Assembly (AA)

revision(s) associated with that stepping.

Nomenclature

Specification Changes are modifications to the current published specifications. These changes will be

incorporated in the next release of the specifications.

Errata are design defects or errors. Characterized errata may cause desktop boards using the Intel845G

chipset’s behavior to deviate from published specifications. Hardware and software designed to be used with

any given Altered Assembly (AA) and BIOS revision level must assume that all errata documented for that

AA and BIOS revision level are present on all desktop boards.

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.
