the ethernet controller is integrated on the system board. it provides an interface for connecting to a 10-mbps, 100-mbps, or 1-gbps network and provides full duplex (fdx) capability, which enables simultaneous transmission and reception of data on the network. if the ethernet port in the computer supports auto-negotiation, the controller detects the data-transfer rate (10base-t, 100base-tx, or 1000base-t) and duplex mode (full-duplex or half-duplex) of the network and automatically operates at that rate and mode.

    you do not have to set any jumpers or configure the controller. however, you must install a device driver to enable the operating system to address the controller. for device drivers and information about configuring the gigabit ethernet controller, go to http://www.ibm.com/pc/support/
