All,

I have started a new thread for this part of my problem, the bridging part
having been solved - thanks, Paul !

To restate:

   eth0 - NC100 Network Everywhere Fast Ethernet 10/100 - PCI Card
          Manf: Linksys, Driver tulip
   eth1 - NC100 Network Everywhere Fast Ethernet 10/100 - PCI Card
          Manf: Linksys, Driver tulip
   eth2 - NC100 Network Everywhere Fast Ethernet 10/100 - PCI Card
          Manf: Linksys, Driver tulip
   eth3 - 3c940 10/100/1000Base-T [Marvell] - Motherboard
          Manf: 3Com, Driver sk98lin

All appear in the Hardware Browser; all appear in the Network Configuration
tool.  Giving all the cards unique IPs, and activating them, ifconfig
reports:

/etc/modprobe.conf contains:

   alias tulip eth0
   alias tulip eth1
   alias tulip eth2
   alias sk98lin eth3

Doing a 'service network restart' says:

   Shutting down interface eth0:              [  OK  ]
   Shutting down interface eth1:              [  OK  ]

and then ifconfig reports:

Any ideas why eth1 and eth2 don't come back up after a 'service network restart'
or what I can do to get them into operation ?
