Is this a known issue and/or something I can safely ignore? I don't think the NVIDIA page is correct. AFAIK all nForce4 chipsets support SATA 3Gbps transfer speeds. The kernel doesn't have any control over the default speed chosen by the controller in any case (though it can force it down to a lower speed). -- Robert Hancock Saskatoon, SK, Canada To email, remove "nospam" from hancockr@nospamshaw.ca Home Page: http://www.roberthancock.com/
