Dubb as far as I know sata raid isn't possible on these as they use the ICH5 not the ICH5R But when I get mine i'm gonna play around with running raid on it. The ICH5R just sets up the raid array in the bios and lets you boot from it but still uses software to do the raid operations, I think anyway. So I think I'm going to see if its possible to maybe use a usb memory device and put some boot files on it and just have it read the usb device or a floppy each time it boots up, might take a couple more seconds if it even works at all. But you still have the benefit of the sata channels being connectd directly and not running through the pci bus. And maybe its possible to just run raid 0 and have it boot without a boot device but I'm not sure how the boot files would be handled since they are on two drives.
