Refer to the

concerning the Pentium III processor. Items contained in the

Pentium III Processor Specification Update that

either do not apply to the D820LP desktop board or have been worked around are noted in this document.

Otherwise, it should be assumed that any processor errata for a given stepping are applicable to the PBA

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 D820LP desktop board’s behavior

to deviate from published specifications. Hardware and software designed to be used with any given Printed

Board Assembly (PBA) and BIOS revision level must assume that all errata documented for that PBA 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.
