ok...
dd if=/boot/vlinuz of=/dev/fd0
is also the same as
cp /boot/vlinuz /dev/fd0
but before you do that you need to do rdev, when i compile my kernels the
build automatically does rdev to them so i overlooked that. sorry
find out which device is used for you root partition (where / is mounted
from). So if my root partition is on the 1st partition of the first ide
drive then i would do the following...
rdev /boot/vlinuz /dev/hda1
you can find out which device the root partition is mounted from by using
the df command.
