Drivers and Utilities For XPS M140 w/XP SP2

Does anyone know what driver or utility I need to install for
connecting to a network via ethernet? I haven’t a clue what it is called
so looking online really didn’t help.

Specs: Dell Inspiron/XPS M140 w/XP SP2. 1 Gig of Ram, 1.74 GHz
Centrino Processor.

Thanks.
