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 AN430TX motherboard’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 are present on all motherboards.
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.
