It's possible/likely, but we don't know for certain at this point. We also don't know what brand hard disks he had connected to ad16 and/or ad18. Older Silicon Image controllers are known for..... well, just read the Wikipedia entry for details. http://en.wikipedia.org/wiki/Silicon_Image_Inc.#Product_alerts I don't have any experience with their newer models, but I'm told they're significantly improved (throughput and reliability-wise). But it is amusing, almost ironic, how Silicon Image bought CMD -- the same company who was infamous for their CMD640 IDE controller causing data corruption... back in 1995. As others have stated already: Intel could make a fortune off of a simple PCIe or PCI-X SATA controller card that's ICH9/ICH10-based. I guess there's more money in forcing people to buy motherboards with said southbridge. -- | Jeremy Chadwick jdc@parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
