Sm bus controller
Sm bus controller (or control systembus controller) is part of the chipset of the microprocessor, which is located inside the computer system unit. This is an in-circuit system bus, which was built on the basis of the I2C bus. It is necessary for the exchange of information of a service character between different chips of the system (SM - in translation, System Management) and, accordingly, management of their settings. The Sm bus controller transmits information to programs that monitor the readings of the hardware sensors. These sensors are vital for system performance and maintain its optimum temperature and voltage.
The controller was developed by Intel for usein its chipsets in 1995. Since then it has been improved, it has become faster and more successfully used in subsequent chipsets. However, this is a relatively slow data bus. Its speed ranges from 10 kHz to 100 kHz.
Sm bus controller is used to communicate withdevices on the motherboard that require relatively low bandwidth, that is, the data transfer rate for these devices is much lower. Such a controller is a simple two-wire bus that connects the motherboard to power supply chips, such as laptop battery packs. It can provide information about the manufacturer and model number of the internal devices, as well as save the current state in standby mode. The device can also report system errors and control parameters.
Since the bus controller is part of the chipset,it can not be accessed by users, which means that it is not possible to change the configurations of this device. The most common problem experienced by users is the lack of controller drivers. Since the sm bus controller is often used for power management, its malfunction can cause problems with the computer associated with the standby mode and the output from it. In this regard, the software for the controller is very important to ensure the correct operation of the system. In case of any failures or unstable operation, the driver must, of course, be reinstalled.
Sm bus controller is included in the majorityIntel chipsets. If you see an unknown device in the Windows Device Manager window or receive an error message "Bus Controller Not Detected," you need to install its driver using the Intel Chipset Installation Utility. If this fails, you can try downloading the software from the manufacturer's website.
To install, perform the following actions:
1. Insert the driver disk into the drive or download the latest version of the required driver. To do this, in the "Support" section of the website, enter the model number of your motherboard or computer.
2. Run the installation wizard.
3. Follow the on-screen instructions to proceed with the installation. In most cases, just click the "Next" button several times to complete the process.
4. Restart the computer after the driver is installed.
Sometimes after reinstalling the driver or software, you will need to enable the SM bus controller. For this:
1. Click the Start button, and then right-click the Computer icon.
2. Click the "Properties" button, and then click "Device Manager".
3. Click the "System Devices" button to expand the tree.
4. Right-click the "SM Bus Controller" icon, and then click "Allow."
5. Exit the window.
Be careful! Any changes in the operating system increase the likelihood of its instability. Make sure that you have backed up the files before you start. And even better, in order to avoid additional problems, contact the specialists for advice and assistance.
