I'm having similar problems, of not being able to boot up the computer from a floppy disk. What I'm seeing is that there isn't a Boot Devise that says just floppy drive it says just about everything else, but that. I hear something going on in the hard drive, I also don't know what else to do after that I hit F2 and check to make sure it looks o.k. unfortunately, I don't really know what I'm looking for. Help. I bought this CPU from a surplus store that says they were tested to make sure they were good, but have no operating system. I bought the Windows System 7 from a vendor. Any ideas what I can do next.
