My new asus doesn't require a floppy either, but I have a serious problem depending on WINDOWS! to stay stable while the program flashes my rom... Mainly because I don't feel like having to order a new bios if something goes wrong, I have already seen it happen... Floppy until the day there is another way that is as stable and error proof.
Maybe what they should do is drop 2 chips on the board, allow you to update online, and then on reboot it verifies the data on the second chip that updated and after verification it re-writes the other bios.
