Thanks. That's a difference I wasn't aware of, and would (because I tend to favor amd) explain why I've never seen a change in enumeration order unless I've done something like unplug my sata cables for maintenance and forget which ones I had plugged in where -- random USB stuff left plugged in doesn't seem to matter, even choosing different boot media from the bios doesn't seem to matter by the time the kernel runs (I'm less sure about grub). -- Duncan - List replies preferred.
