Connecting Front Panel Cable - AOpen MK79G-N Installation Manual

6. IEEE 1394 Connectors (MK79G-1394 only)
With IEEE1394 MAC Embedded in nVIDIA nForce2-GT chipsets (with AGERE FW802A),
the IEEE 1394 provides data transfer rate up to 400Mb/s, and USB just has 12Mbps.
Hence, the IEEE 1394 interface can connect with the devices that need high data
transferring performance, such as digital camera, scanner or others IEEE 1394 devices.
Please use the proper cable to connect with devices.
7. Support 2
This motherboard provides six USB connectors to connect USB devices, such as mouse,
keyboard, modem, printer, etc. There are four connectors on the PC99 back panel. You
can use proper cable to connect the other USB connector to the back panel or front panel
of chassis.
