I have an ASRock Extreme3 Gen3 motherboard and I'm just wondering because I have this plug named 1394 and somebody said it had to go into a firewire or a port named 1394 or ieee1394 and I can't find it anywhere. Please help.
This board does not have a Firewire port (aka 1394/ieee1394). This port is largely being phased out in favor of USB.
You can find 3rd party PCI/PCI-E Firewire cards though, for pretty cheap that will work in almost all motherboards.
