The only way that won't ruin your board(provided you have the right BIOS version for the right board model) is to have the BIOS file on a pen drive and use M-Flash to flash the BIOS. Also, last I checked, you should be good to go out of the box for that processor.
To note, you should be able to see the BIOS version the board shipped with by looking at the sticker that's on the board's 24pin connector.
