I'm noob when it comes to building my own computer (Though I know my hardware quite well) I'm wondering how hard it will be to flash the bios on a DFI LP DK 790FXB, since I want to put a Phenom 2 in my new build can I do it easily, do I need a floppy drive, can I do it before I install my OS? your answers are much appreciated.
