Intel Desktop Board D945GCL Specification Update 5
Terminology
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 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.
