Advanced SCSI Programming Interface (ASPI)
Currently the most popular universal driver as most SCSI peripheral manufacturers write drivers which interface with ASPI. Windows 95 and 98 provide in-built support for ASPI. The Windows 98 start-up disk provides the most common ASPI drivers so that SCSI CD drives can be accessed, for loading or re-loading Windows 98. The A once stood for Adaptec, the originator.
