The Adaptec SCSI Programming Interface (ASPI) was designed by Adaptec as a means of communicating to SCSI peripherals attached to Adaptec controllers. Versions were made for DOS, Windows, OS/2, and NetWare. A few years ago, Adaptec renamed it as Advanced SCSI Programming Interface, released the specification to the public, and encouraged developers to introduce ASPI-compliant device drivers.
ASPI defines a software layer between the device controllers and the operating system. By communicating with the ASPI drivers, we don't have to write individual drivers for every make and model of SCSI controller board.
This distribution contains ASPI drivers for Windows 95, 98, ME, NT, 2000, XP, and Win2003. In addition, it includes several ASPI-related programs. They are:
ASPICHK - Determines whether or not ASPI drivers are installed and operational, and reports the ASPI revision number.
ASPIINST - Installs drivers for Windows 95, 98, ME, NT, 2000, and Win2003.
INSTALL.BAT - Installs ASPI drivers for Windows XP.
All of these programs are licensed by us for use with S.M.A.R.T. Disk Monitor, and are not in the public domain.
The drivers included are revision 4.71. If you are already running ASPI drivers, and you have no problems, then there is no reason to upgrade.
