Different flags can be used to limit the output to specific classes of hardware (e.g. disk, LANIC, processor, memory etc).
Also if you have online diagnostics installed the Support Tools Manager can provide very detailed information on the hardware of the machine. Use the cstm (command line driven), mstm (menu driven) or xstm (graphical interface) commands. The latter provides a graphical representation of the hardware and makes it easier to understand what is hanging off what.
