Universal Serial Bus Ports
Two Universal Serial Bus ports (USB 2.0) are
located beside the Keyboard and Mouse PS2
ports. Two additional Type A ports (USB2/3)
are included on the motherboard. See the
table on the right for pin defi nitions.
USB Headers
Four USB 2.0 headers (USB4/5 and USB6/7)
are also included on the motherboard. These
may be connected to provide front side
access. A USB cable (not included) is needed
for the connection. See the table on the right

Fan Headers
This motherboard has six fan headers
(Fan1 to Fan6). These 4-pin fans headers
are backward compatible with 3-pin fans.
However, fan speed control is available
for 4-pin fans only. The fan speeds are
controlled by the BIOS. See the table on the
right for pin defi nitions
Serial Ports
The COM1 serial port is located beside the
VGA port. Refer to the motherboard layout
for the location of the COM2 header. See the
