Hello,
I'm with Mandrake 9.1 and I want to install two ethernet cards ne2000 compatible
the problem is that only one card can work at the time.
I did the following :
added to file /etc/modules.conf these lines :

alias eth0 ne
alias eth1 ne
options ne irq=5,11 io=0x320,0x300

file /etc/sysconfig/network-scripts/ifcfg-eth0 :

DEVICE=eth0
BOOTPROTO=static
IPADDR=10.20.21.5
NETMASK=255.255.0.0
BROADCAST=10.20.255.255
ONBOOT=yes
MII_NOT_SUPPORTED=no

file /etc/sysconfig/network-scripts/ifcfg-eth1 :

DEVICE=eth1
BOOTPROTO=static
IPADDR=10.20.21.6
NETMASK=255.255.0.0
BROADCAST=10.20.255.255
ONBOOT=yes
MII_NOT_SUPPORTED=no

added to file /etc/rc.d/rc.local this line

modprobe ne

only eth0 can work.
the command line /etc/init.d/network restart gives me (for eth1) this message :
Activation de l'interface eth1 : ne device eth1 does not seem to be present, delaying initialization [ECHEC]
