I still have a Via SP13000 mb, which used to be my mythbox. ISTR that
the motherboard had a jumper setting, *as well as the BIOS setting* to
enable WOL. Something to do with the normal shutdown clearing a
particular BIOS bit. There was/is a similar problem with the auto-wake
alarm settings, you have to do things *just* right. ( IE needs the
correct incantation and/or sacrifice.)
You might try searching about the alarm settings problem. That mught
point in the correct direction. Sorry I cannot be more specific.
