Be sure to connect these connectors to the 24-pin (JPW1) and the 8-pin
(JPW2/JPW3) power connectors on the motherboard. Failure in doing so
will void the manufacturer warranty on your power supply and motherboard.
It is strongly recommended that you use a high quality power supply that
meets ATX power supply Specication 2.02 or above. It must also be SSI
compliant. (For more information, please refer to the web site at http://www.
ssiforum.org/). Additionally, in areas where noisy power transmission is
present, you may choose to install a line lter to shield the computer from
noise. It is recommended that you also install a power surge protector to
help avoid problems caused by power surges.
1-7 Super I/O
The Super I/O supports two high-speed, 16550 compatible serial communication
ports (UARTs). Each UART includes a 16-byte send/receive FIFO, a programmable
baud rate generator, complete modem control capability and a processor interrupt
system. Both UARTs provide legacy speed with baud rate of up to 115.2 Kbps
as well as an advanced speed with baud rates of 250 K, 500 K, or 1 Mb/s, which
support higher speed modems.
The Super I/O provides functions that comply with ACPI (Advanced Conguration
and Power Interface), which includes support of legacy and ACPI power manage-
ment through an SMI or SCI function pin. It also features auto power management
to reduce power consumption.
