ABSTRACT:
Access to internal configuration registers on a computer system's chipset using an external micro-controller is provided. A SMB configuration read command including a register address may be received from an external micro-controller. Access to an internal bus may be requested from a bus arbiter. If internal bus access is granted, the SMB configuration read command may be forwarded to a device including the identified register address using the internal bus. In response to the SMB configuration read command, configuration register values from the device may be received. The configuration register values may be forwarded to the external micro-controller.
