IntelDesktop Board D850EMV2 Specification Update

PREFACE

This document is an update to the specifications contained in the IntelDesktop Board D850EMV2 Technical

Product Specification (Order Number A94395). 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 desktop board D850EMV2.

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82850 Chipset Family: 82850/82850E Memory Controller Hub (MCH) Specification Update

(Order Number 298247) for specification updates concerning the 82850/82850E MCH Controller and that

may apply to the desktop board D850EMV2. 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82801BA I/O Controller Hub (ICH) Specification Update (Order Number 290677) for

specification updates concerning the 82801 I/O Controller Hub and that may apply to the desktop board

D850EMV2. Unless otherwise noted in this document, it should be assumed that any 82801BA 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 the desktop board D850EMV2’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.
