#dmesg

8. Run the dmesg command to see which devices the e1000 driver was mapped to:

#dmesg

divert: allocating divert_blk for eth3

e1000: eth3: e1000_probe: Intel(R) PRO/1000 Network Connection

e1000: eth2: e1000_watchdog: NIC Link is Up 1000 Mbps Full Duplex

e1000: eth3: e1000_watchdog: NIC Link is Up 1000 Mbps Full Duplex

9.Add the e1000 interfaces to the /etc/modules.conf file for 2.4 based kernels and to /etc/modprobe.conf file for 2.6 based kernels.

alias eth2 e1000

alias eth3 e1000

10.Use the ethtool command to check the parameter configurations that apply to the e1000 driver.

#ethtool eth3
