wake up signal (low active)
If you have installed a LAN card, use the cable provided with the card to plug into the WOL
connector onboard. This enables the Wake On LAN (WOL1) 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.
IRDA: Infrared header
The motherboard supports an Infrared (IRDA) data port. Infrared ports allow the wireless
exchange of information between your computer and similarly equipped devices such as
printers, laptops, Personal Digital Assistants (PDAs), and other computers.
