To explain, I had to first install the Samsung SSD SATA port on the motherboard to be recognized. Once installed with Windows 7 I finally unclip Sata cable from the motherboard and put it on the port sata 1 (0 is better) of the module. And there, finally, after restart, the SSD system was recognized by the BIOS via the module "ASUS U3S6 Storage". You will understand, install an SSD on the same module with AHCI enabled, is not a simple thing. By cons, use the module directly connected to the SATA port on the motherboard is not a problem with disk internal or external storages. I hope I was clear enough.
