the ethernet controller is integrated on the system board. it provides an interface for connecting to a 10-mbps, 100-mbps, or 1000-mbps 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 of the network (10base-t, 100base-tx, or 1000base-t) and automatically operates at that rate, in full-duplex or half-duplex mode, as appropriate. the ethernet controller supports optional modes, such as teaming, priority packets, load balancing, fault tolerance, and virtual lans, which provide better performance, security, and throughput. these modes apply to the integrated ethernet controller and to controllers on supported ethernet adapters.

    you do not need to set any jumpers or configure the controller. however, you must install a device driver to enable the operating system to address the controller. the device drivers are available on the device drivers and ibm enhanced diagnostics cd. for the latest device drivers and information about configuring your ethernet controller, go to the ibm support web site at http://www.ibm.com/pc/support.
