Dear all, I'm not an expert. As I know the Intel processors and AMD as well, both can write some hide bios parameters from Windows OS.
Step 1. To can have a working WOL, is neccesary to install first an windows, doesn't meter witch version. Try to configure the BIOS & Windows network settings. Internet is full of information.
Step 2. Check the network, PING your PC & be careful about the router settings. If exist any router between your PC and PC on witch will be OMV installed please set it careful ( don't use NAT). Read on internet about routers configuration
Step 3. Download an WOL magic packet program & with your OMV-PC (now with Windows OS) online scan the network. See if you find your OMV-PC. Shutdown the OMV-PC & send WOL magic packets.
If works go to next step, if not go back.
Step 4. Install a clean Open Media Vault on your PC, better with fix IP address. Be very careful how is configured the name of your workgroup. If chose for standard (HOME), should change any PC in your network to have the same WORKGROUP NAME.
Step 5. Ping the OMV-PC to be sure that the network is fine. Here is included the router
Step 6. Activate WOL on OMV-PC web gui interface/Network. Do an WOL with the same program used before.
P.S. Durring OMV installation please check error messages, in special about network configuration. If you can't see any issue, WOL should work fine. If yes, should take in consideration to replace the network card & reinstall OMV.
If is OK enjoy, if not go back.
