Then I would move both cards to dufferent slots, set the IRQ's and I/O address to somethine else like IRQ 5 I/O 280, make those changes in the visual mode of the kernel editor. Then try to bring the interfaces up with ifconfig ep0 10.10.0.1 netmask 255.255.255.0 If you still can't bring the interfaces up, then I would pick up some cheap NE2000 cards, and see if the problem persists... Also what's the number on the 3com cards? Btw here's what my ifconfig look like... 1:09pm@cplkagan~>ifconfig -a ed2: flags=8943 mtu 1500 inet 192.168.1.1 netmask 0xffffff00 broadcast 192.168.1.255 ether 00:40:05:49:3a:00 ep0: flags=8843 mtu 1500 inet 10.10.0.1 netmask 0xffffff00 broadcast 10.10.0.255 ether 00:20:af:69:82:bf tun0: flags=8051 mtu 1500 inet 204.24.41.142 --> 209.6.64.21 netmask 0xffffff00 inet 204.24.41.1 --> 204.24.41.1 netmask 0xffffff00 inet 209.6.64.1 --> 209.6.64.59 netmask 0xffffff00 sl0: flags=c010 mtu 552 lo0: flags=8049 mtu 16384 inet 127.0.0.1 netmask 0xff000000
