    Huh - your floppy is working?

    Mine does not (with 2.4.0pre10-test1 that is):

    [Marvin:~#] dd if=/dev/fd0 |od -c |more
    2880+0 records in
    2880+0 records out
    0000000 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0
    *
    5500000
    [Marvin:~#]


    This floppy currently holds my MILO image so output is definitively wrong :-)
    I also saw pure random data (fragments from libc etc.) on different runs.

    AXPpci33 ev4 UP
    gcc version 2.96 20000925 (experimental)
