Actually..... * Old-nvidia is ADMA, and I have docs under NDA * nvidia themselves say they are uninterested in NCQ support for their older ADMA controllers, though they don't mind if I implement it * New-nvidia is AHCI, and thus will support NCQ when AHCI does * slight correction to the above: sil24 will do NCQ, I don't think sil does Jeff
