C2SBM-Q User’s Manual 1-7 Versatile Media Capabilities High Definition Audio The High Definition Audio Controller embedded in the ICH9 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 C2SBM-Q provides the user with a surreal audio experience that is larger than life.
I/O Virtualization Technology (VT-d) With the Intel ICH9 built in, the C2SBM-Q supports I/O Virtualization Technology (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 parti- tions. This feature is available when a processor that supports the virtualization of platforms is installed on the motherboard.
1-8 Super I/O The disk drive adapter functions of the Super I/O chip include a data separator, write pre-compensation circuitry, decode logic, data rate selection, a clock generator, drive interface control logic and interrupt and DMA logic. 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 four 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 sys- tem.
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 ACPI (Advanced Configura- tion and Power Interface), which includes support of legacy and ACPI power man- agement through a SMI or SCI function pin. It also features auto power management to reduce power consumption. 1-12
