Before, I haven't build the kernel.
I need to prepare the file /etc/conf.modules:

alias eth0 ne
options ne io=0x300
alias eth1 3c59x


And today, I try to build the kernel.
I have chosen the [Y] in both 3com NIC support and NE2000 support.
So, I won't got this two modules(ne.o and 3c59x.o) any more during building.
Then, the problem happened !!!
On starting:
...
Enable IPv4 packet forwarding.
modprobe: can't locate module net-pf-5
...
eth1: unknown interface.     (NE2000 NIC change from eth0 to eth1)
modprobe: can't locate module net-pf-5


What's more, I try to copy back the files:
    ne.o       to /lib/modules/2.2.3/net/ne.o
    3c59x.o to /lib/modules/2.2.3/net/3c59x.o

Then the system report:
...
modprobe: can't locate module net-pf-5
insmod: /lib/modules/2.2.3/net/3c59x.o: kernel module version mismatch
             /lib/modules/2.2.3/net/3c59x.o was compiled for kernel version
2.0.36 while this kernel is version 2.2.3.
eht1: unknown interface.
modprobe: can't locate module net-pf-5
...


What should I do now, is that supports been compiled to kernel yet ???
I have chosen [Y] for these 2 NIC support already !!!
Would you please offer your Kindly Help ?
