What is the sm bus controller?

• Answer:

  The SMBus Controller (or System Management Bus Controller) is part of a microprocessor's chipset, found inside a computer casing. The SMBus controller provides information to programs that monitor readings from hardware sensors. These sensors are vital to a system's performance, and enable the computer to maintain an optimal temperature and voltage.CompatibilityOperating systems after Windows 98 have support for the device. A software known as the driver instructs the operating system on how to operate the device.FunctionThe SMBus controller is used to communicate with devices on a system board (motherboard) that require relatively low bandwidths, meaning data transfer rates for these devices are much lower. Such devices may include a laptop's rechargeable battery subsystem, and temperature and voltage subsystems.ApplicationsThe SMBus can provide information about manufacturer and model number of internal devices, and can save current state for a suspended event. The device can also report on errors and accept control parameters.ConfigurationsSince the SMBus controller is part of the chipset, it cannot be accessed by users, meaning that the device does not allow modifications or configurations.DriverIf you have problems with the SMBus controller, you can download the software from the manufacturer's site. You can also install a generic driver from the Intel site, provided it is compatible with the generic software.Source:http://articles.networktechs.com/114-p1.phphttp://www.pcuser.com.au/pcuser/hs2.nsf/lookup+1/442835CDBE31D365CA256CAA0049888A
