Your computer comes with preinstalled Smart Connect software. To
enable faster startup, your computer ships with this software disabled. To
enable Smart Connect:
Click the Start button, select Settings, and click Control Panel. The
Control Panel window appears.
Click the System icon. The System Properties window appears. Click
the Device Manager tab.
Double-click Sony i.LINK(1394) Adapter. The Sony i.LINK(1394)
Adapter window appears. Click the Enable Device button.
Click OK. The Sony i.LINK(1394) Adapter icon should no longer have
an "X" on it. This means Smart Connect is now enabled.
Close all windows, and restart your computer in order for the new
settings to take effect.
Now your Smart Connect software is ready to use. Note that when you
use Smart Connect to connect two VAIO computers, you must assign
each computer a unique name by which it can be identified when the two
computers are networked. See the Smart Connect online Help for more
information.
