In this context, em(4) refers to the OpenBSD driver (man em), not the actual physical device. Many em-devices support WoL at BIOS-level and machines with such setup will cold boot successfully. Resuming from suspend/hibernate is an altogheter different affair. It works partly on an em-machine I have. At least for the first zzz/arp cycle. I'm wondering: are there any OpenBSD drivers that support WoL at all? Regards, Erling
