Abstract This 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 intelligent storage devices. It includes the Packet Command feature set implemented by devices commonly known as ATAPI devices. This standard maintains a high degree of compatibility with the AT Attachment-3 Interface (ATA-3), ANSI X3.298-1997, and while providing additional functions, is not intended to require changes to presently in- stalled devices or existing software.

Consensus is established when, in the judgement of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made towards their resolution. The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether he has approved the standards or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards. The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of any American National Standard. Moreover, no person shall have the right or authority to issue an interpretation of an American National Standard in the name of the American National Standards Institute. Requests for interpretations should be addressed to the secretariat or sponsor whose name appears on the title page of this standard. CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time. The procedures of the American National Standards Institute require that action be taken periodically to reaffirm, revise, or withdraw this standard. Purchasers of American National Standards may receive current information on all standards by calling or writing the American National Standards Institute.

However, nei- ther the developers nor the publisher have undertaken a patent search in order to identify which, if any, patents may apply to this standard. As of the date of publication of this standard, following calls 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 publication of this standard, no position is taken with respect to the validity of this claim or of any rights in connection therewith. The known patent holder(s) has (have), however, filed a statement of willingness to grant a license under these rights on reasonable and nondiscriminatory terms and conditions to applicants desiring to ob- tain such a license. Details may be obtained from the publisher. No further patent search is con- ducted by the developer or publisher in respect to any standard it processes. No representation is made or implied that this is the only license that may be required to avoid infringement in the use of this standard.

This AT Attachment with Packet Interface Extension (ATA/ATAPI-4) standard is de- signed to maintain a high degree of compatibility with the AT Attachment-3 Interface (ATA-3) standard and the packet command feature set implemented by devices com- monly known as ATAPI devices while providing the advantages of additional features and functions. This standard was developed by the ATA ad hoc working group of Accredited Stan- dards Committee NCITS during 1995-97. The standards approval process started in 1997. This document includes six annexes. Annex A is normative and is considered part of the standard; all other annexes are informative and are not considered part of the standard. Requests for interpretation, suggestions for improvement and addenda, or defect re- ports are welcome. They should be sent to the NCITS Secretariat, Information Tech- nology Industry Council, 1250 Eye Street, NW, Suite 200, Washington, DC 20005- 3922. This standard was processed and approved for submittal to ANSI by NCITS. Com- mittee approval of the standard does not necessarily imply that all committee mem- bers voted for its approval. At the time it approved this standard, NCITS had the following members: Karen Higginbottom, Chair (Vacant), Vice-Chair Monica Vago, Secretary Organization Represented Name of Representative AMP, Inc. John Hill Charles Brill (Alt.) Apple Computer, Inc. David Michael Jerry Kellenbenz (Alt.) AT covering the inter- face cabling requirements of the interface and DC cables and connectors. Clause 5 contains the signal descriptions of the AT Attachment Interface. Clause 6 describes the general operating requirements of the AT Attachment In- terface. Clause 7 contains descriptions of the registers of the AT Attachment Interface. Clause 8 contains descriptions of the commands of the AT Attachment Interface.
