ASPI, the Advanced SCSI Programming Interface provides an API originated by Adaptec which standardizes communication on a computer bus between a SCSI host adapter on the one hand and SCSI (and ATAPI) peripherals on the other.
History
ASPI was provided by these drivers:
- DOS: ASPI4DOS.SYS
- Windows 3.1x: WINASPI.DLL
- Win32:
- WNASPI32.DLL, APIX.VXD and ASPIENUM.VXD (Windows 95, 98 and ME);
- WNASPI32.DLL, ASPI32.SYS (Windows NT, 2000, XP)
FreeDOS also supports ASPI with USBASPI.SYS driver.
