I have had an Athlon64 system (Asus K8V motherboard) system set up since September and have been running Suse v9.0-64 since November. I have been having the same problems with the VIA 8237 chipset and SATA support that others have had - the VIA and Promise controllers are not supported with the 2.4.21 kernel. After lurking here, I saw mention of the 3ware SATA product working natively and took a look into it - I ordered the lowest end board - 8006 - and just received and installed it. After poking around and getting the 3w module loaded, I was able to partition and mount the drive (my system drive is just plain old IDE). It is in use as I write this... Just wanted to say thanks for the discussions and recommendations - I have a working SATA drive now! ......Chuck Arlington, Texas, USA
