Versatile Media Capabilities

High Definition Audio
The High Definition Audio Controller embedded in the ICH9R delivers up to 4
codecs that can be used for different types of codecs, such as audio and modem
codecs. Operating at 3.3V or 1.5V, the embedded Audio Controller supports a
multi-channel audio stream, 32-bit sample depth, up to 192 kHz of same rate, and
can be used with a variety of microphones for input. With these versatile audio
capabilities built in, the C2SBX/C2SBX+ provides the user with a surreal audio
experience that is larger than life.
I/O Virtualization Technology (VT-d)
With the Intel ICH9R built in, the C2SBX/C2SBX+ supports I/O Virtualization Tech-
nology (VT-d) that enables multiple operating systems and applications to run in
independent partitions. Each partition uses its own subset of host physical memory
and behaves like a virtual machine (VM), providing isolation and protection across
multiple partitions. This feature is available when a processor that supports the
virtualization of platforms is installed on the motherboard.

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 two 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 provides functions that comply with the Advanced Configuration
and Power Interface (ACPI), which includes support of legacy and ACPI power
management through a SMI or SCI function pin. It also features auto power man-
agement to reduce power consumption.
