    This is not a problem to deal with in the kernel - what if there is
    hardware other than a floppy controller at that address?

    The bootloader needs to ensure that the hardware is at least in a
    sensible state when the kernel is entered. Infact, unless the system
    is being booted from floppy, why is the BIOS accessing the floppy at

    Re-configure the BIOS not to try to boot from the floppy, or to seek
    the drive to see whether it is capable of 40 or 80 tracks.

    If that is not possible, (on a laptop with an obscure BIOS for
    example), add a delay to the bootloader. Assumng interupts are still
    enabled, the BIOS will switch the floppy off after a few seconds.
