I'm building a computer out of some of my older parts but I never have had a raid on this motherboard before. That's the problem I cant seem to get it to get the hard drives on a raid to work. I think, I have tried about every bios setting and jumper setting there is and the raid array will not detecting my 2 sata hard drives but when I go to install windows it shows 2 hard drives in the xp pro (32 bit) windows install. They are K8N MSI neo motherboard and 2 Western Digital Caviar hard drives. I really don't know what else to try other then updating the bios or if someone can help me more would be much appreciated.
