multiple ethernet boards

[Brian <lxy@antares.cloudnet.com>]

I'm setting up a firewall server.  It has 3 network cards.. eth0 is to the
DSL, eth1 is to the DMZ, eth2 is to my masquerade.  The cards are are
identical NE2000 compatible.  I 'modprobe ne.o io=0x240 irq=10' and eth0
pops out.  ifconfig brings the interface up with all the IPs and it
communicates just fine.  Apparently I can only load a module once, because
I do 'modprobe io=0x300 irq=3' for my next card, and I don't get an eth1.
Any ideas how I can make 3 identical cards be assigned to eth0, eth1, and
eth2?  Thanks.
