Thanks a ton, JackNaylorPE. The manual is a extremely valuable resource, which I never cared to look and assumed unreliable. It talks about two identical disk drives. So I can't do it? If raid is possible, I wish to know when does 'setting up raid' appear... as in just the basic logical steps --- Install Bios(in my case Flash bios), Install Win7 OS(SSD or HD?), Setup Raid (which sata ports?), does it affect partitioning etc.? If raid is not possible, AHCI is the option? Consider me a noob.
