A8M2N-LA Motherboard BIOS

Hi I'm trying to find the option to use Wake On Lan (WOL) from the BIOS. Unfortunately it is locked by HP so I cannot use WOL. Can someone help me out and unlock this feature?

Here is the bios I'm using http://h10025.www1.hp.com/ewfrf/wc/softw...8&sw_lang=

Thanks in advance.
