Firstly, thank you for your quickly response.
vbarderks: i`ll try to upgrade the bios by myself as soon as i can boot the MoBo.
nails: I tried to use a single card but it's not work. I'm using a i5 3570K. I don't know what is the bios version and i'm thinking how can i will upgrade it without boot sequence or some other init screen.
Thanks again and best regards,
