I thought Wake On Lan was a feature of the hardware bios rather than the
OS.

The OS has to leave the NIC in a state where WoL can work, and an
OS (or rather a driver) which doesn't know about WoL may well leave
the card in a state where WoL won't work.

If you multi-boot different OS's, this can be a particular problem.

Also, some cards will run their own ARP when the system is powered
down so the WoL packet can be routed to an IP address (usually over
UDP) rather than using the raw ethernet address (which is not routable
across networks). This adds another whole layer to go wrong,
particularly in DHCP environments.
