Helped a friend this afternoon that was trying to install a new SATA hard drive in his son's PC. The PC is about 4 years old and one of the earlier models with onboard SATA and RAID. XP did not recognize the hard drive. I tried to walk him thru the BIOS setting to enable the drive and disable RAID (he didn't want it) but there were no settings for the SATA connectors. We tried a BIOS update and that failed. At last I sent him the RAID drivers for his motherboard and asked that he use the F6 option to install these on his next attempt - this worked and now he's finishing the install.
