A defective Firewire port on your Mac Mini can reduce its usefulness. The port is used to connect other devices to the computer. If the Firewire port stops responding or becomes damaged, you may have to send it in for repair. Before you decide to send in your Mac Mini, you can attempt to fix it yourself by resetting the nonvolatile RAM, also known as NVRAM. Once the NVRAM is reset the Firewire port should begin responding again. Do not attempt to physically repair the NVRAM as you may void the Apple warranty.
