[SOLVED] [Wake-on-LAN] Does this motherboard support it?

Hello

I use an Atom-based, low-power computer from MSI as a home NAS.

I'd like to use WoL to wake it up from suspend mode, let a remote backup application do its thing, and put the NAS back to suspend mode.

The BIOS only contains the following info in the Chipset > South Bridge Configuation section: "Onboard LAN Controller", which is currently enabled.

dmidecode says the BIOS manufacturer is "MICRO-STAR INTERNATIONAL CO., LTD" (it could actually be just OEM), and reports the following relevant infos:

Code:

Wake-up Type: Power Switch

Handle 0x0018, DMI type 10, 6 bytes
On Board Device Information
        Type: Ethernet
        Status: Enabled
        Description:  Onboard GBE

Handle 0x0017, DMI type 9, 13 bytes
System Slot Information
        Designation: PCIE1
        Type: x1 PCI Express
        Current Usage: Available
        Length: Other
        ID: 1
        Characteristics:
                3.3 V is provided
                PME signal is supported
                SMBus signal is supported

Does it mean the on-board Ethernet port supports WoL, or should I get a PCI Express Ethernet board that does?

And am I correct in understanding that I won't actually need to install anything in Linux, and just let the remote software send magic packets to the NAS' MAC address on UDP9 to inrteract with the NAS?

Thank you.

Don't know if I've ever seen a bios that supports WOL and didn't offer a choice to enable or disable it. I've seen plenty of NIC cards that support WOL and yet won't work on a system that didn't support it.

I'd have to imagine that the specs at the OEM would say what wake on may be supported.

May be in different are of bios. Look under power maybe.
