A kernel config abstract is not very useful in this case, since it lacks
information that is important. You should either post the *entire*
file, or the output of the following command:
$ diff -u GENERIC MYKERNEL
where MYKERNEL is the name of your custom config file.

What do you mean by "it can not boot"?

Try starting with a copy of GENERIC, like this:
# cd /usr/src/sys/i386/conf
# cp GENERIC MYKERNEL
and then comment out parts of the file. You should be able to use your
ed0 interface as long as you don't comment out or delete the following
lines of MYKERNEL:
device ether # Ethernet support
device miibus # MII bus support
device ed # NE[12]000, SMC Ultra, 3c503, DS8390 cards
