System Panel Connector (X5)
That connector is used by a different kind of signals. There is no standard cable adapter available.
Connector type: DF14 20pin header 1.25 mm
SMBus/I²C
The ICH9 contains an SMBus (System Management Bus) Host interface that allows the processor to
communicate with SMBus slaves. This interface is compatible with most I2C devices. Special I2C commands are
implemented.
The ICH9’s SMBus host controller provides a mechanism for the processor to initiate communications with
SMBus peripherals (slaves). Also, the ICH9 supports slave functionality, including the Host Notify protocol.
Hence, the host controller supports eight command protocols of the SMBus interface: Quick Command, Send
Byte, Receive Byte, Write Byte/Word, Read Byte/Word, Process Call, Block Read/Write, and Host Notify.
ICH9’s SMBus also implements hardware-based Packet Error Checking for data robustness and the Address
Resolution Protocol (ARP) to dynamically provide address to all SMBus devices.
