WOL capability. In addition, an onboard LAN controller can also support WOL

without any connection to the WOL header. The 3-pin WOL header is to be used

with a LAN add-on card only.

Note: Wake-On-LAN requires 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 X7QC3/X7QCE can only accommodate 24-pin ATX power supply. Although

most power supplies generally meet the speciﬁ cations required by the mother-

board, some are inadequate. You should use one that will supply at least 400W

of power. In addition, the 12V 8-pin is also required for adequate power supply to

the CPU. Also your power supply must supply 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 detailed 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.

1-7 Super I/O

The disk drive adapter functions of the Super I/O chip include a ﬂ oppy disk drive

controller that is compatible with industry standard 82077/765, a data separator,

write pre-compensation circuitry, decode logic, data rate selection, a clock genera-

tor, 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 ﬂ oppy disk drives. The Super I/O supports 360 Kb,

720 Kb, 1.2 Mb, 1.44 Mb or 2.88 Mb 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 se-

rial 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

Kbps, 500 Kbps, or 1 Mbps, 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-
