This is a multi issue problem.autoprobe did not find my
3c509 card in my machine so I could not configure it from
install.

config mode to manual
and the enable toggle is set
I set io port at 0x300
irq at 5
name as lupis02.interesect.com
alias as lupis02
IP address 192.168.1.1
netmask = 255.255.255.0
net device to eth0
kernal module 3c509


I then completed the install and used linux to add it as
eth0 in as adapter 1 in the hosts section of networking.

when I reboot I get a message in the log that there was an
error from /lib/modules/2.2.5.-15/net/3c509.o invalid
parameter io

if I remove the configuration from adapter 1 and issue  a
modprobe 3c509
then a modprobe 3c509 io=300 irq=5
and then ifconfig eth0 192.168.1.1 netmask 255.255.255.0
broadcast 192.168.1.255
then connection works and comes up.

I get a similar problem if I do it through control-panel

when I look in then kernal daeomn configuration in control
panel I see entries for 3c509 and for eth0 when I install
from linuxconfig.

when I do it manually I only see an entry for eth0

lsmod shows 3c509 being loaded after a manual configuration.

ifconfig shows eth0 as being correct after the manual
install as well.

As a result I suspect that there may be a bug in linuxconf
in setting the io parameter for 3c509
