Introduction
Wake-On-LAN (WOL)
Wake-On-LAN is defined as the ability of a management application to re-
motely power up a computer that is powered off. Remote PC setup, up-
dates and asset tracking can occur after hours and on weekends so that
daily LAN traffic is kept to a minimum and users are not interrupted. The
motherboard has a 3-pin header (WOL) to connect to the 3-pin header on a
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 SUPER X6DVA-4G/X6DVA-EG can only accommodate ATX 24-pin
power supplies. Although most power supplies generally meet the specifi-
cations required by the CPU, some are inadequate. You should use one
that will supply at least 400W of power and includes the additional +12V, 8-
pin power connector - an even higher wattage power supply is recom-
mended for high-load configurations. Also your power supply must supply
1.5A for the Ethernet ports.
NOTE: An additional 12V 8-pin power connector (PW2) is required to
support Intel Xeon CPUs. Failure to provide this extra power will
result in instability of the CPU after only a few minutes of opera-
tion. See Section 2-5 for details on connecting 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
