While ATA was codified by the CAM working group, one should not be under the impression that CAM was limited to any particular physical interface. CAM stands for "Common Access Method" and is applicable to a number of physical interfaces, including SCSI. Future Domain, for example, patterned their drivers along CAM conventions, using CCB (CAM control blocks). Adaptec, on the other hand, perferred ASPI. Of the two, CAM is far more flexible and varied. After Adaptec acquired FD, they provided a "middle" driver to convert ASPI calls to CAM. Just saying... --Chuck
