No. I don't think I have any pure-SATA machines.

Its current value lies in allowing SCSI and SATA scans to take place simultaneously; otherwise SATA forces SCSI to finish its scans before it starts. It also allows the SATA asynchronous scan code to become synchronous. -- Intel are signing my paycheques ... these opinions are still mine "Bill, look, we understand that you're interested in selling us this operating system, but compare it to ours.
