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 D915PSY. 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®915G and 915P Chipset: Specification Update (Order Number 301468) for
specification updates concerning the 82915P MCH Controller and that may apply to the desktop
board D915PSY. 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®IO Controller Hub 6 (ICH6) Family Specification Update (Order Number
301474) for specification updates concerning the 82801ER I/O Controller Hub and that may
apply to the desktop board D915PSY. Unless otherwise noted in this document, it should be
assumed that any ICH 6 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
D915PSY’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.
