is motherboard supports Wake from on Board LAN. To use this function, please make
sure that the “Wake on Magic Packet from power o state” is enabled in Device Manager
> Intel® Ethernet Connection > Power Management. And the “PCI Devices Power On” is
enabled in UEFI SETUP UTILITY > Advanced > ACPI Conguration. Aer that, onboard
LAN1&2 can wake up S5 under OS.
If you install Intel® LAN utility or Marvell SATA utility, this motherboard may fail Win-
dows® Hardware Quality Lab (WHQL) certication tests. If you install the drivers only, it
will pass the WHQL tests.
