5.1.3 Setting the RAID item in BIOS
You must enable the RAID function in the BIOS Setup before creating RAID sets using SATA HDDs. To do this:
1.Enter the BIOS Setup during POST.
2.Go to the Advanced menu > SATA Configuration, and then press <Enter>.
3.Set the SATA Mode item to [RAID Mode]. 4.Save your changes, and then exit the BIOS Setup.
Make sure you read through the user guide. RAID is in chapter 5 at the bottom. I don't have that motherboard so I can't vouch for its accuracy, but it looks pretty thorough based on the way its written.
I'm reasonably certain my son's computer has the same RAID controller, and I have his set up in RAID 0 also. It's Friday so he might be on it a while tonight. But I'll load the configuration utility and look at how it's set when he's away from it. Don't forget about the thread
