If you replace your network card with one that uses a different network driver (for example, smc), before rebooting the second time, rename the /etc/hostname.olddriver0 file to /etc/hostname.newdriver0.
Any time you add, remove, or replace hardware, run the Configuration Assistant utility.
For example, to replace a 3Com EtherLink III card with an SMC EtherEZ card, run the following command as root:
# mv /etc/hostname.elx0 /etc/hostname.smc0 |
and then perform a reconfiguration boot for your changes to take effect:
# touch /reconfigure # reboot |
