I have a Gigabyte 880 ud3-h 3.0. mobo. I am getting a new SSD drive. In the bios I would like to know how exactly to change the port 0 where the drive will reside to ACHI mode from IDE mode. I think I would have to leave the port that my CDrom is connected to IDE to be able to boot and install the Window's 7 installation disk. Thanks in advance.
