Advanced SCSI Peripheral Interface
The ASPI layer is a collection of programs (DLLs) 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.
