4、tThis 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 impleme
5、nted bydevices commonly known as ATAPI devices. It also includes the Serial Transport Protocols and PhysicalInterconnect for AT Atachment devices commonly known as Serial ATA.This standard maintains a high degree of compatibility with the AT Attachment Interface with Packet Inter-face - 6 (ATA/ATAPI
6、-6), ANSI INCITS 361-2002, and while providing additional functions, is not intendedto require changes to presently installed devices or existing software.Copyright American National Standards Institute Provided by IHS under license with ANSINot for ResaleNo reproduction or networking permitted with
