Advanced SCSI Peripheral Interface
     
         (ASPI) A set of libraries designed to
        provide programs running under {Microsoft Windows} with a
        consistent interface for accessing {SCSI} devices.  ASPI has
        become a {de facto standard}.
     
        The ASPI layer is a collection of programs ({DLL}s) that
        together implement the ASPI interface.  Many problems are
        caused by device manufacturers packaging incomplete sets of
        these DLLs with their hardware, often with incorrect date
        stamps, causing newer versions to get replaced with old.
        ASPICHK from Adaptec will check the ASPI components installed
        on a computer.
     
        The latest ASPI layer as of March 1999 is 1014.
     
        The {ATAPI} standard for {IDE} devices makes them look to the
        system like SCSI devices and allows them to work through ASPI.
