Introduction
Network Interface Card (NIC) that has WOL capability. Wake-On-LAN must
be enabled in BIOS. Note that Wake-On-LAN can only be used with an ATX
2.01 (or above) compliant power supply.
1-6 Power Supply
As with all computer products, a stable power source is necessary for
proper and reliable operation. It is even more important for processors that
have high CPU clock rates.
The X6DH8-G2/X6DHE-G2 can only accommodates 24-pin ATX power sup-
plies. Although most power supplies generally meet the specifications re-
quired by the CPU, some are inadequate. You should use one that will
supply at least 400W of power connector. In addition, the 12V 4-pin power
supply (J32) - is also required to ensure adequate power supply to the
system. Also your power supply must supply 1.5A for the Ethernet ports.
NOTE: The + 12V 8-pin Aux. Power Connector (J1D1) is also required
to support Intel Xeon CPUs. Failure to provide this extra power will
result in CPU PWR Failure. See Section 2-5 for details on connect-
ing the power supply.
It is strongly recommended that you use a high quality power supply that
meets ATX power supply Specification 2.02 or above. It must also be SSI
compliant (info at http://www.ssiforum.org/). Additionally, in areas where
noisy power transmission is present, you may choose to install a line filter
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 disk drive adapter functions of the Super I/O chip include a floppy disk
drive controller that is compatible with industry standard 82077/765, a data
separator, write pre-compensation circuitry, decode logic, data rate selec-
tion, a clock generator, drive interface control logic and interrupt and DMA
logic. The wide range of functions integrated onto the Super I/O greatly
reduces the number of components required for interfacing with floppy disk
drives. The Super I/O supports 360 K, 720 K, 1.2 M, 1.44 M or 2.88 M disk
drives and data transfer rates of 250 Kb/s, 500 Kb/s or 1 Mb/s.It also
provides two high-speed, 16550 compatible serial communication ports
(UARTs), one of which supports serial infrared communication. Each UART
includes a 16-byte send/receive FIFO, a programmable baud rate generator,
