    Hmm.  That's one I've never seen before.  On the off-hand that it is
    related to the serial port, try creating a /boot.config file with
    -V in it (video only boot).

You should be able to bypass the third stage loader (which is what failed)
and get to your kernel by hitting escape just after the first stage loader.

It says:

Default: F1

    hit F1, then immediately hit Esc.  You should break into the stage-2
    loader.  It will say something like:

I don't actually see this, hitting Esc just drops me to the next part:

    DragonFly/i386 boot
    Default: 0:ad(0,a)/boot/loader
    boot: <garbage>

    hit backspace a few times to get rid of the garbage, then boot your kernel
    directory e.g. by typing:  /kernel

I'll have to remember this. I've been getting around it by booting one of the install disks, and copying /boot/loader.old back to /boot/loader.

    Then mess around with /boot.config (note: it's a file in /, not in /boot)
    and reboot and see if you can get around the problem.


Setting -V does not fix it.
