PREFACE
This document is an update to the specifications contained in the following documents:
•Pentium®II Processor Developer’s Manual (Order Number 243502)
•P6 Family of Processors Hardware Developer’s Manual (Order Number 244001)
•Intel®Celeron® Processor Datasheet (Document Number 243658)
•Intel® 64 and Intel IA-32 Architectures Software Developer’s Manual, Volumes 1, 2-A, 2-B, 3-A and 3-B
(Document numbers 253665, 253666, 253667, 253668, and 253669, respectively.)
It is intended for hardware system manufacturers and software developers of applications, operating systems,
or tools. It contains S-Specs, Errata, Documentation Changes, Specification Clarifications and, Specification
Changes.
Nomenclature
S-Spec Number is a five-digit code used to identify products. Products are differentiated by their unique
characteristics, e.g., core speed, L2 cache size, package type, etc. as described in the processor identification
information table. Care should be taken to read all notes associated with each S-Spec number.
Errata are design defects or errors. Errata may cause the Celeron processor’s behavior to deviate from
published specifications. Hardware and software designed to be used with any given processor must assume
that all errata documented for that processor are present on all devices unless otherwise noted.
Documentation Changes include typos, errors, or omissions from 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.
Specification Changes are modifications to the current published specifications for the Celeron processor.
These changes will be incorporated in the next release of the specifications.
