Hi:

I rebuilt the kernel with "option IPX", but it didn't seem to work.
Below was what I did:

1) create a new configure file IPXKERNEL enabling "option IPX"
freebsd-yc# cat /sys/i386/conf/IPXKERNEL
include GENERIC
ident IPXKERNEL
options	IPX

2) make buildkerel KERNCONF=IPXKERNEL. When finised, I found that the
ipx source code did get compiled, but hadn't been linked into a kernel
module.
freebsd-yc# find /usr/obj/usr/src/sys/IPXKERNEL/ | grep  ipx
/usr/obj/usr/src/sys/IPXKERNEL/modules/usr/src/sys/modules/arcnet/opt_ipx.h
/usr/obj/usr/src/sys/IPXKERNEL/modules/usr/src/sys/modules/if_ef/opt_ipx.h
/usr/obj/usr/src/sys/IPXKERNEL/modules/usr/src/sys/modules/if_tun/opt_ipx.h
/usr/obj/usr/src/sys/IPXKERNEL/modules/usr/src/sys/modules/netgraph/iface/opt_ipx.h
/usr/obj/usr/src/sys/IPXKERNEL/modules/usr/src/sys/modules/smbfs/opt_ipx.h
/usr/obj/usr/src/sys/IPXKERNEL/modules/usr/src/sys/modules/sppp/opt_ipx.h
/usr/obj/usr/src/sys/IPXKERNEL/modules/usr/src/sys/modules/wlan/opt_ipx.h
/usr/obj/usr/src/sys/IPXKERNEL/opt_ipx.h
/usr/obj/usr/src/sys/IPXKERNEL/ipx.o
/usr/obj/usr/src/sys/IPXKERNEL/ipx_cksum.o
/usr/obj/usr/src/sys/IPXKERNEL/ipx_input.o
/usr/obj/usr/src/sys/IPXKERNEL/ipx_outputfl.o
/usr/obj/usr/src/sys/IPXKERNEL/ipx_pcb.o
/usr/obj/usr/src/sys/IPXKERNEL/ipx_proto.o
/usr/obj/usr/src/sys/IPXKERNEL/ipx_usrreq.o

3) Still I installed the new kernel with "make installkernel
KERNCONF=IPXKERNEL", and as expected, it was exactly the same to the
old one.
freebsd-yc# ls /boot/kernel > kernel.txt
freebsd-yc# ls /boot/kernel.old/ > kernelold.txt
freebsd-yc# diff kernel.txt kernelold.txt

So do you have any idea about this? The information of my system is:
freebsd-yc# uname -a
FreeBSD freebsd-yc.vm 8.3-RELEASE FreeBSD 8.3-RELEASE #0: Mon Oct 15
11:20:49 CST 2012
root at freebsd-yc.vm:/usr/obj/usr/src/sys/IPXKERNEL  i386

Thanks,
