This adapter cable converts the 1394 pins from most AT-style Pentium(R) and newer motherboards to two standard IEEE-1394a 6-pin connections. This 2-outlet 1394 bracket will provide the missing link to PCs that have IEEE-1394 capability, but do not have connectors on the PC to use it. This bracket connects to an internal board connector to provide two IEEE-1394 ports on the back panel.Please Note: FireWire(R) and the FireWire symbol are trademarks of Apple Computer, Inc., registered in the U.S. and other countries.
