Thuban, I can't answer your floppy drive/BIOS question, but one thing I can say is that I spent 6 solid weeks with more hours than I want to think of researching for my new build. One thing I can tell you and that is go to any motherboard forum sites and you will see every board out there will give you something to worry about. For example, the DFI Lanparty boards such as the Ultra-D and Sli versions are the hottest boards out there, but I challenge you to go over to their official DFI-Street.com and read all the troubles people are experiencing with these boards. The same goes with Asus, MSI, etc., etc., etc. What I am trying to say is that no board and no manufacter is exempt from problem boards.
My research through many site reviews, reads, and personal messenging led me to choose this board. I am still in the midst of a build, but I am confident that any problems I have people here can help.
