The Basic Sections of BIOS Setup. Part II

PnP/PCI Configurations

The parameters of this section manage by resource allocation between peripherals. This function is usually addressed to the system, leaving automatic resource allocation by default.


PC Health Status

All modern motherboards are equipped with monitoring sensors of working temperatures, voltages and fan speeds. Their current indicators are displayed in a separate section of BIOS Setup called “PC Health Status” or “H/W Monitor”. The indicators of sensors are used in automatic protection systems from overheating, and appropriate parameters are displayed to identify the threshold of protection.


Frequency/Voltage Control

This section includes operating voltage and frequency for processor, chipset, memory, video adapters and other. With default parameters all frequencies and voltage are set automatically in modern computers that ensures the reliable operation of the system. If the parameters of this section are changes manually, the acceleration may be done, that is to make a processor, memory and other components work on higher frequencies.

The section for frequency and voltage setting may be called differently, for example, it is called MB Intelligent Tweaker in some Gygabyte boards, or Cell Menu – in MSI boards.


Load Fail-Safe Defaults

(Load BIOS Setup Defaults)

The command resets all BIOS settings to the default values. The safer values of all parameters are set that ensure high stability of system operation. Choosing this point, the window usually appears where you must confirm chosen action by pressing the key Y.




Load Optimized Defaults

(Load High Performance)

This command sets those BIOS settings which ensure the system’s optimal performance saving its stability. Depending on a particular model of the motherboard, these values may vary but, as a rule, optimized settings differ from default settings by rapid passing of POST procedure, faster operating regimes of a memory, accelerated buses’ operation and some other parameters. Sometimes optimized parameters are inconsistent with available hardware and the system may be unstable after this command. In this case, one should return to default settings by pressing “Load Fail-Safe Defaults” and then set the system to an optimal operation manually.


Set Supervisor Password

and Set User Password

These commands set administrative and user passwords to enter BIOS or to boot a computer respectively.
