wow, the manual for that board really sucks. i'm not sure what to tell you. since the motherboard supports RAID 0/1, there has to be some setting somewhere, i just don't know where to tell you to look. also, i know those boards are usually tricky. my last MSI board required me to have the motherboard options for both PATA and SATA enabled in order to have it detect the SATA drive, and i have no idea why. sometimes MSI board are cake to setup, and sometimes they are a severe pain in the butt. if there are no RAID settings, you'll probably want to mess with the PATA and SATA settings in the bios and try to find a combination that works.
