are inadequate. In addition, the two 12V 8-pin power connections are also required
to ensure adequate power supply to the system. Also your power supply must sup-
ply 1.5A for the Ethernet ports.
It is strongly recommended that you use a high quality power supply that meets ATX
power supply Specifi cation 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
fi 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.
Warning: To prevent damage to the power supply or motherboard, please
use a power supply that contains a 24-pin and two 8-pin power connectors.
Be sure to connect these connectors to the 24-pin (JPW1) and the two
8-pin (JPW2,JPW3) power connectors on the motherboard for adequate
power supply to your system. Failure in doing so will void the manufacturer
warranty on your power supply and motherboard.
1-8 Super I/O
The wide range of functions integrated onto the Super I/O greatly reduces the
number of components required for interfacing with fl oppy disk drives. It also
provides 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 Confi guration
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.
