BS AMD 8328 RENUMBERS THIS STANDARD TO BS EN 29318 PT2: 1995 Describes the Logical Level 2 Interface for disk drives. Its purpose is to facilitate the development and utilization of a device level interface which permits the interconnection of disk slave peripherals to a controller. Does not replace any existing standard, but it does complement other Intelligent Peripheral Interface standards. Provides a definition of the device specific portion of a family of standards called the Intelligent Peripheral Interface. Intended to isolate the host from changes in peripherals by providing a "function generic" command set to allow the connection of multiple types of peripherals. To accomplish this the design includes device-specific and device-generic command sets, both utilizing a common physical bus.
