Chapter 1: Introduction
The SUPER X6DAT-G/X6DAi-G accommodates ATX power supplies.
Al-
though most power supplies generally meet the specifications required by
the CPU, some are inadequate. You should use one that will supply at least
400W of power.
A 12V 8-pin power connection (at J1D1) is required
for CPU power consumption, and an
additional 12V 4-pin power
connection (J32) is also recommended for heavy load configura-
tions.) 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 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.

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).
Each UART includes a 16-byte send/receive FIFO, a program-
mable baud rate generator, complete modem control capability and a pro-
cessor 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 supports one PC-compatible printer port (SPP), Bi-directional
Printer Port (BPP) , Enhanced Parallel Port (EPP) or Extended Capabilities
Port (ECP).
The Super I/O provides functions that comply with ACPI (Advanced Con-
figuration and Power Interface), which includes support of legacy and ACPI
power management through an SMI or SCI function pin.
It also features
auto power management to reduce power consumption.
