WOL isn't related to ACPI power modes. Suspend (ACPI S3) isn't necessary to have WOL power on the system-- Celeron systems (e.g. D201GLY2) all lack ACPI S3 support, and nearly all of them can wake from LAN when configured with ethtool.
The best way to debug this is to simply set the ethtool option (wol g) for the network interface (probably eth0 in your case), verify that the setting was made (use ethtool to show configured settings) and shut down the system (poweroff). Send a magic packet to the correct MAC address using your favorite method (Windows, another *NIX box, home router, etc.) and see whether anything happens. Assuming that fails (and you've probably tried something similar) the suspects are the NIC and BIOS. Google the specific NIC (lspci -v can be useful to determine what the exact model) and scour the BIOS for relevant options. Modern WOL relies on the NIC sending a "PME" signal over the PCI bus while the system is in ACPI S5 state, so make sure anything PME related is enabled. Detailed MB manuals (like those for Intel boards) often identify the PCI signals they can handle (search for "PME"). I assume your power supply provides normal standby power when the system is powered off (usually an LED on the board will be lit to indicate this). Have seen some specialized/miniature PSU+case combinations take liberties with the ATX spec in this area so also confirm there is power to the NIC in S5 state. -- syburgh ------------------------------------------------------------------------ syburgh's Profile: http://forums.slimdevices.com/member.php?userid=14239 View this thread: http://forums.slimdevices.com/showthread.php?t=51123 _______________________________________________ unix mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/unix
