• Do not plug the IEEE 1394 bracket (2x5-pin) cable into the USB header.
• Prior to installing the USB bracket, be sure to turn off your computer and unplug the power
cord from the power outlet to prevent damage to the USB bracket.
When the system is in S4/S5 mode, only the USB ports routed to the F_USB1 header can sup-
port the ON/OFF Charge function.

 Usethisjumper to clear theCMOSvalues (e.g. date information andBIOScongurations) and reset
the CMOS values to factory defaults. To clear the CMOS values, place a jumper cap on the two pins to
temporarily short the two pins or use a metal object like a screwdriver to touch the two pins for a few
seconds.
