First, after each machine is booted, you should check dmesg to determine that the card was found and assigned a driver. My 3-com card looks like this in dmesg: 1 3C5x9 board(s) on ISA found at 0x300 ep0 at 0x300-0x30f irq 10 on isa ep0: aui/utp/bnc[*BNC*] address 00:20:af:be:eb:e0 And the green light should be on. After that, you can ifconfig ep0 inet 10.10.10.3 netmask 0xffffff00 And similarly for the other box. You can look at ifconfig -a to see all the interfaces, and ifconfig -au to see what is up and running. A ping from one box to the other should then work, and the routes should be established. netstat -rn should show the MAC address of the card in the other box. Sounds to me like the failure is in finding the cards and assigning drivers in the first place (getting the irq and address right for each one). If you have a dos program or if either gets running on Windows, you can look and see what resources it's using.
