I think I got stuck at same point. Weird thing for me was that after setting up SATA1-4 as RAID and 5-6 as IDE, you have to save and restart. Then I had to press F8 to display boot menu, then in the nano-second it was displayed, press CTRL+F to get the RAID menu to come up. Man was that *obnoxiously* well hidden. I had to find it myself as the manual doesn't even say (and I'm doing 10 years later, so all posts are long since buried.
