I like to Hardware-encode the MAC addresses into the ROM, so I donīt need
an running server. I have two NICīs , one for use and one if the first will
fail later. So when I send the wol magic packet to two MAC adresses, it
shoud work for a long time. Of cause if the secound NIC fail too, I need to burn
new ROMīs, but this is OK for me.

Nice to hear, it is posible. I think so, too. ;-)
But have you an idear, how to build a wol magic packet without an OS
running?
