I've probably got this totally wrong, so please put me right somebody, 
(and I'm taking into account the site mentioned by Mike, as well as 
postings subsequent to Fintan's):

but I thought WOL was from a dormant, or suspended state - not from 
completely OFF (like you'd normally have to press the big button on the 
front of the case to make things start, if WOL didn't work).

Several machines I deal with, including two very recent and fairly 
pricey ones, have the usual Power Management area in BIOS, and there are 
two choices for suspend - S1 and S3 - S3 being the most complete, 
suspending to RAM and even closing down the CPU, as well as HDD, etc.

A machine I'm using at home as a webserver is set to S1, and indeed 
comes out of S1 Suspension for a LAN event (or indeed anyone coming in 
from WAN with the website address).  The WAN calls are port forwarded 
through the router to the webserver (this has to be set up in the 
router), and up jumps the server.  I'm experimenting with S3 this evening.

Other BIOS settings on the Power Management page are also needed - I'll 
detail those if anyone is interested.  I'm guessing that this PC would 
do all the WOL stuff because it has the WOL settings in BIOS, and the 
NIC is integrated in the mainboard.

Awaiting being put right.
