Super I/O - Supermicro X6DLP-EG2 User Manual

Chapter 1: Introduction
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 (info. 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.

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 the 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 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 in-
cludes 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 a 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 the ACPI (Advanced Confi gura-
tion and Power Interface), which includes support of legacy and ACPI power man-
agement through an SMI or SCI function pin. It also features auto power manage-
ment to reduce power consumption.
