Installing the Motherboard
WOL: Wake On LAN connector (optional)
If you have installed an LAN card, use the cable provided with the card to plug into the WOL
connector onboard. This enables the Wake On LAN (WOL) feature. When your system is
in a power-saving mode, any LAN signal automatically resumes the system. You must
enable this item using the Power Management page of the Setup Utility in the BIOS. See
Chapter 3 for more information.
