Thanks das_stig, I found that out yesterday afternoon after posting my thread. Found out my P5N-E SLI has no AHCI support either. No wonder I couldn't find the damn thing in BIOS (or anywhere else)! Seems several folks are really steamed at ASUS for this problem. Guess I won't be tweaking my new SSD after all. I mis-wrote about not finding the RAID set-up. Thanks for your response, hauswulf
