Monitoring

The activities of the hardware that are connected to the motherboard are monitored by the BIOS built-in hardware monitoring features. However, the model of the motherboard determines the type and number of monitoring features of the BIOS. The hardware monitoring page of the BIOS is used to view the following:

Temperature: There is a heat sensor in the motherboard. This heat sensor is responsible for monitoring any rise in temperature in the hardware component. There exists a common heat sensor in every CPU. This heat sensor is responsible for monitoring the temperature of the CPU. If the temperature is high then it increases the speed of the fan of the CPU to cool it. In such a case, some BIOS setups also slow the speed of the CPU to reduce the temperature of the CPU. If the temperature is very hot, the BIOS may shut down the computer system in order to prevent the CPU from getting damaged.

There are some other heat sensors in the motherboard, which are used to monitor the temperature inside the case of the CPU or power supply. Apart from that, there are some heat sensors that can monitor the temperature of the RAM, processor, chip sets, and some other specific hardware components. To prevent the overheating, the BIOS generally shutdown the computer system or increases the speed of the fan.

Fan speed: The BIOS is also responsible for monitoring the speed of the fan. In some BIOS setup, the user is allowed to set the speed of the fan manually to get the specific result. The following are some common types of fan that are available in the CPU:

 

 

 

Standard fan: In this type of fan, the speed is adjusted automatically on the basis of the temperature of the CPU, power supply, CPU case, or any other hardware components.

Turbo fan: In this type of fan, the speed is very high. No other fan can have so much speed as turbo fan. Silent fan: In this type of fan, the speed is minimized so that no sound or noise of fan can be heard.

Manual fan: In this type of fan, the user gets the opportunity to control the speed of the fan. There is a fan speed control setting in this type of fan and with the help of this setting user can easily adjust the speed.

Voltage: The voltage of the CPU can also be monitored with the help of the voltage regulator that exists in the CPU. It is very essential to monitor the voltage of the CPU because the components of computer can get damaged because of very high or low voltage. The amount of the voltage in the CPU should be always proper. So, it is necessary to make sure that the power supply is operating properly. The voltage regulator of the motherboard may get damaged if the power supply is unable to provide the correct voltage to the CPU. In such case, the user will have to either repair or replace the motherboard.

Clock and speed bus: Some BIOS setup can also monitor the CPU clock and buses. This is necessary to determine whether the CPU settings have been determined correctly by the BIOS entered manually by the client or the manufacturer of the computer. This is very essential as incorrect bus speed can cause increased heat inside the CPU, which in turn can cause RAM or other specific hardware components to malfunction.

Intrusion detection: Now-a-days computer cases have a switch connected to the motherboard which triggers in case someone tries to open it. BIOS can be set in such a way that it can record if the switch is triggered. This setup helps the owner to find out if computer case has been tampered by someone.
