3、ariatInformation Technology Industry CouncilApproved December 13, 2000 American 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 integra

4、tors, software suppliers,and suppliers of intelligent 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 Extensions (ATA/ATAPI

5、-4), NCITS 317-1998, and while providing additional functions, is not intend-ed to require changes to presently installed devices or existing software.Copyright American National Standards Institute Provided by IHS under license with ANSI Not for ResaleNo reproduction or networking permitted without

6、 license from IHS-,-,-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 established when, in the judgement of the ANSI Board ofStandards Review, subst

7、antial 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 be considered, and that a concerted effort be madetowards their resolution.The u

8、se 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, processes, or procedures not conforming to the standards.The American National

9、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 American 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. The procedures of the American National StandardsInstitute require that action

11、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.American National StandardPublished byAmerican National Standards Institute, I

However, nei-ther the developers nor the publisher have undertaken

14、a patent search in order to identify which, ifany, patents may apply to this standard. As of the date of publication of this standard, followingcalls for the identification of patents that may be required for the implementation of the standard,notice of one or more such claims has been received. By

15、publication of this standard, no positionis taken with respect to the validity of this claim or of any rights in connection therewith. The knownpatent holder(s) has (have), however, filed a statement of willingness to grant a license underthese rights on reasonable and nondiscriminatory terms and co
