Apologies, let me clarify...

I would create a custom kernel config by executing (assumptions: your kernel
source is stored at /usr/src/sys):

	cd /usr/src/sys/i386/conf

NOTE: Replace "i386" with another architecture (such as "amd64") depending on
your needs.

	touch MYGENERIC

NOTE: Followint steps will overwrite "MYGENERIC" in the current working
directory if it already exists. If this file exists already, move it aside
before proceeding.

	echo "include GENERIC" > MYGENERIC
	echo "ident MYGENERIC" >> MYGENERIC
	echo "machine i386" >> MYGENERIC

NOTE: Again, replace "i386" with your desired architecture if not "i386".

	echo "nodevice et" >> MYGENERIC

Now, configure and compile your kernel by executing:

	config -g MYGENERIC
	cd ../compile/MYGENERIC
	make cleandepend && make depend && make

Your new kernel is named "kernel" in the current working directory.
