Hi, Sorry to mind you. Since 1 month i have a strange trouble on my Tyan 2890 and one of my raptor 1500 Sata1. I have changed : - the power supply - the hard drive, sata wire - the power wire of the hard drive is dedicated to the disk - a clear bios ... I really don t know what to do rightnow. My bios is set on P-ATA (S-ATA doesn t change anything). I still obtain some message, kind : on this partition, there is : - /home (sdc1) - /temp (sdc5 extended) I ask me if it is not a Nvidia trouble... I really don t know. maybe your experience could help me Yoan For errors, please read my attachment
