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 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 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 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 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 Configuration
and Power Interface), which includes support of legacy and ACPI power manage-
ment through an SMI or SCI function pin. It also features auto power management
to reduce power consumption.

Intelligent Platform Management Interface (IPMI)
IPMI is a management interface that enables a user or administrator to remotely
access, monitor, diagnose and manage servers and networks. To use the IPMI
2.0 slot on this motherboard, use Supermicro's AOC-SIM1U, AOC-SIM1U+ or the
AOC-SIMLC Intelligent Management module, and the IPMIView software utility that
is included in the package.
With the Raritan ® KIRA
the AOC-SIM1U/SIM1U+ and the AOC-SIMLC supports the 2D/VGA-compatible
Graphics Core with the PCI interface, Virtual Media, and Keyboard/Video/Mouse
(KVM) Redirection modules.
The KIRA 100 BMC interfaces with the host system via a PCI interface to com-
municate with the graphics core. It supports USB 2.0 and 1.1 for remote keyboard/
mouse/virtual media emulation. It also provides LPC interface to control Super IO
functions. The KIRA 100 is connected to the network via an external Ethernet PHY
module to provide network interfacing and management.
