2-24 Chapter 2: Hardware information
8. USB header (10-1 pin USB56)
If the USB ports on the rear panel are inadequate, a USB header is
available for additional USB ports. The USB header complies with USB
2.0 specification that supports up to 480 Mbps connection speed and
allows faster Internet connection, interactive gaming, and simultaneous
running of high-speed peripherals.
You must install the driver before you can use the USB 2.0 capability.
NEVER connect a 1394 cable to the USB connector. Doing so will
damage the motherboard!
