I enabled PCI-E event is it enough from the BIOS part? With Q87, I had no issue at all but Q77 seems to be a little harder. The Windows NIC driver is a little older than on Q87 but it is an Intel Driver and the Windows power management is configure on both.
Any idea if Q77 has Something specific?
No, there are no differences from the Q87. Make sure that support for WOL is enabled in the Windows driver configuration and in the BIOS (where there may be separate configuration parameters for S3, S4 and S5).
Do you mean other parameters than enabling PCI-E event may not be enough for the BIOS part? In Windows, the NIC power management is fully enable, in the NIC driver l'option with Magic packet too. Would I need to set Something else in the NIC driver?
Well, I don't have this particular board, so I cannot speak in specifics, but most boards have some sort of NIC-specific WOL parameter(s) and related power settings (WOL from S4/S5, etc.). Sounds like you have the driver parameters set, however.
