2、proved September 20, 2002American National Standards Institute, Inc.AbstractThis standard specifies the AT Attachment Interface between host systems and storage devices. It pro-vides a common attachment interface for systems manufacturers, system integrators, software suppliers,and suppliers of inte
3、lligent storage devices. It includes the Packet Command feature set implemented bydevices commonly known as ATAPI devices.This standard maintains a high degree of compatibility with the AT Attachment Interface with Packet Inter-face - 5 (ATA/ATAPI-5), ANSI NCITS 340-2000, and while providing additio
4、nal functions, is not intendedto require changes to presently installed devices or existing software.Approval of an American National Standard requires review by ANSI that therequirements for due process, consensus, and other criteria for approval havebeen met by the standards developer.Consensus is
5、 established when, in the judgement of the ANSI Board ofStandards Review, substantial agreement has been reached by directly andmaterially affected interests. Substantial agreement means much more thana simple majority, but not necessarily unanimity. Consensus requires that allviews and objections b
6、e considered, and that a concerted effort be madetowards their resolution.The use of American National Standards is completely voluntary; theirexistence does not in any respect preclude anyone, whether he has approvedthe standards or not, from manufacturing, marketing, purchasing, or usingproducts,
7、processes, or procedures not conforming to the standards.The American National Standards Institute does not develop standards andwill in no circumstances give an interpretation of any American NationalStandard. Moreover, no person shall have the right or authority to issue aninterpretation of an Ame
8、rican National Standard in the name of the AmericanNational Standards Institute. Requests for interpretations should beaddressed to the secretariat or sponsor whose name appears on the titlepage of this standard.CAUTION NOTICE: This American National Standard may be revised orwithdrawn at any time.
9、The procedures of the American National StandardsInstitute require that action be taken periodically to reaffirm, revise, orwithdraw this standard. Purchasers of American National Standards mayreceive current information on all standards by calling or writing the AmericanNational Standards Institute
