i have an iMac G3 firewire that is not recognizing my firewire QPS CD burner. Are the firewire ports replaceable alone or do you have to replace the entire card (USB, 1394, Sound, etc). How do you take the iMac apart to get to that? is it easy? i know it might not be the computer's firewire ports that are bad but i'm asking just in case the need arises. thanks.
