disconnect the network cable.

Accessing the Network at Startup

To connect the notebook to a PXE (Preboot eXecution
Environment) server during startup, you must enable the internal
NIC for startup, then respond to the Network Service Boot
prompt each time you want to connect to the server.
To enable the NIC for startup and set the notebook to display the
Network Service Boot prompt each time the notebook is started
or restarted, set your preferences in the Setup utility. The Setup
utility is not a Windows utility and does not support the
TouchPad. For more information about using the Setup utility,
refers to the "Using the Setup Utility" section in Chapter 9 of
this guide.
To respond to the Network Service Boot prompt, press F12
while the prompt F12 = Boot from LAN appears very briefly in
the lower left corner of the screen before Windows loads.
