It's called Wake-On-LAN (WOL). A portion of the configuration of this feature is done from the BIOS, but it is actually a feature of the Intel Network Adapters.
In order to use this feature, you need to appropriately configure the Windows driver for the Network Adapter and the BIOS to support WOL. You also need source(s) on your subnet that can generate the magic packet that is used to request the wake-up.
Here is a snapshot showing how to configure the Windows driver WOL feature:
And here is a snapshot from the BIOS Configuration, showing the setting for WOL (set to do normal boot when signal received with system in S5 state):
Hope this helps,
