    I tried to make a boot floppy using the command

      dd if=/boot/vmlinuz-2.2.19pre17 of=/dev/fd0

    (where the in_file name is the name of my kernel,
    which boots fine from hard disk (using LILO)).

    That command apeared to work fine, and reported
    "1956+1 records in" (and the same for "records out").

    But when I try to boot from that floppy, it gives
    the usual message (something indicating that it is
    transfering data from the floppy into memory) followed
    by about 3 rows of dots, then it goes into an infinite
    loop, repeatedly writing 5 short lines of text to the
    monitor. To stop it, I have to power-down, which
    fortunately doesn't seem to cause any problem with
    a subsequent boot from hard disk of the same kernel.
    The size of the kernel is 1,001,473 bytes, which
    I think should fit on my floppy (about 1.4 Mbyte).

    When I tried the same thing with an earlier kernel
    (vmlinuz-2.0.32, with 446,281 bytes), the dd command
    reported 871+1 records in and out, and I was able
    to boot just fine from that floppy.

    Anyone know what's wrong?
