BIOS System Setup Utilities

BIOS setup utilities offer many uses apart from a simple interface to save the results and making selections. Some of the uses of a BIOS setup utility are listed below:

  • The BIOS setup utility allows checking if the clock is losing time because of a dying battery.
  • The BIOS setup utility offers diagnostic routines that the BIOS can use to analyse the quality and state of the components that it inspects during a boot-up process. In this case, the inspection is done at a deeper level.
  • If the computer overheats and starts making noises, the BIOS configuration utility can be used to access built-in diagnostics for checking the rotational speed of the motherboard. The noise can be from the bearings of one or more fans that might be making them run slower, leading to decreased cooling capacity.

Generally, the BIOS setup utility has a page that gives access to information, such as live readings of the CPU’s temperature and the ambient temperature inside the system unit. This page allows you to set the temperature at which the BIOS- should sound a warning tone and also the temperature at which the BIOS should shut down the system for protection. This page also lets you monitor instantaneous fan speeds along with the voltage levels of the CPU, bus speed, and other important aspects to ensure that all of them are working within suitable ranges. You can also set the lower fan speed threshold at which the system will give a warning. In several cases, you can also change some of such levels for overclocking. The BIOS utility is also used for setting the system clock higher than what the CPU is rated for. You could also change the levels to achieve undervolt. Undervolt refers to decreasing the voltage of the RAM and CPU for lowering down the heat production and power consumption.
