2、rican National Standards Institute, Inc.AbstractThis standard specifies the AT Attachment command set used to communicate between host systems andstorage devices. This provides a common command set for systems manufacturers, system integrators,software suppliers, and suppliers of storage devices. Th

This standard main-tains a high degree of compatibility with the AT Attachment 8 - ATA/ATAPI Command Set (ATA8-ACS) (seeANSI INCITS 453-2008).Approval of an American National Standard r
4、equires 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, substantial agreement has been reached by directly andmaterially affec

11、ION: The developers of this standard have requested that holders of patents that may be re-quired for the implementation of the standard disclose such patents to the publisher. However, nei-ther the developers nor the publisher have undertaken a patent search in order to identify which, ifany, paten
12、ts 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 publication of this standard, no positionis taken with r
13、espect 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 conditions to applicants desiring to ob-tain such a licens
14、e. 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 ismade or implied that this is the only license that may be required to avoid infringement in the use ofthis standard.iConten
