Hi Jantjo,
Thank you for writing back.
You may add this command line to enable WOL: BoootUtil -nic=xx -WOLE
For more Command Options on BootUtil, please check out our website: http://downloadmirror.intel.com/19186/eng/BootUtil.txt
Make sure the WOL is also enabled in the motherboard's BIOS (Example: Wake on S3/S5 etc.)
In case you still weren't able to make WOL work, kindly contact the system or motherboard manufacturer to check if the system can support WOL and if there are special settings to enable this feature.
Hope this is helpful.
Sincerely,
Sandy
