What is BIOS?

In this blog, we are to talk about what is bios system and how to work a bios system on your computer.

A “BIOS” (Basic Input/output system) is software or firmware capable of starting your computer system.

The BIOS Power on Self Test is started when the computer system is started, but to ensure that all the hardware connected to the system is working properly.

It completes the maintenance of all the basic things of the system by checking every hardware connected to the computer system and loads the operating system (OS) which you can modify by changing the BIOS settings to improve the performance of your computer system.

Or can troubleshoot system problems. The BIOS running in your computer’s memory includes all the various drivers that provide an interface to the hardware on the OS. The BIOS ROM is preloaded into the chip.

Where is the BIOS Stored?

In the BIOS motherboard, there is a chip named EEPROM (Electrically Erasable and Programmable Read-Only Memory) in which it is stored.

This is a non-volatile ROM chip, meaning you can update the BIOS or even rewrite it accordingly.

Main functions of BIOS

The BIOS is a collection of programs embedded in one or more chips depending on the design of your computer system.

Collections of programs embedded in these chips are first loaded before the OS (Operating system) is loaded.

There are four main functions of BIOS are available in most computers

  • POST: Checks your computer system’s processor memory, chipsets, videos, adapters, disk controllers, disk drives, keyboards, and other hardware to check if they are working properly.
  • SETUP: enables configuring your computer system’s motherboard and chipset settings System configuration and setup programs are typically a menu-based program that is activated by pressing a Special Key during POST.
  • BIOS: It is a collection of drivers that acts as a basic interface between your computer system and the OS and your hardware when it boots.
  • BOOTSTRAP LOADER: Hard disk is required to load the OS, hard disk drives read the boot sector. It is a program that is stored in the ROM or EPROM of your computer that when the computer is powered on. Is automated by the processor. Loading the OS from a floppy disk or hard disk into the main memory (RAM) of the computer makes the program work until the process is successfully completed in the boot memory (RAM), then the main copy is made to the OS, then Till the user cannot use the computer.

A successful transfer of the OS to the RAM or boot process is indicated by displaying a boot prompt on a computer monitor such as A: /> or C: /> or if you have Windows OS or Linux OS on your screen in your system. The load remains.

How do I access BIOS?

If your computer system is not able to use all the features of new software or hardware, it means a need to upgrade the BIOS.

By updating the BIOS, it adds additional functions and fixes all Errors and Bugs. You can download the BIOS update from the motherboard manufacturer’s website.

Two different methods are available to upgrade the motherboard BIOS.

Changing BIOS Chip: You can change your motherboard’s BIOS chip to upgrade your computer system’s motherboard BIOS, in a new system’s motherboard, the original BIOS chip is removed and a new BIOS chip is inserted.

But your new BIOS chip must match your old system’s motherboard and chipset, so you can use its existing CPU.

This upgrade feature is provided by the BIOS manufacturer. However, if the BIOS is of a DIP package that is not permanently attached to the motherboard, then the BIOS chip is removed and you can install a new version (Version) of the chip on the system motherboard.

In addition, you can get the updated BIOS by removing the old motherboard and installing a new motherboard into the system.

Via Flash Update: Newer versions enable the user to upgrade the System Motherboard BIOS, update software is downloaded and installed on a disk that is a Flash upgradeable BIOS.

This disk is then used to boot the computer. The new BIOS code is then copied to the BIOS chip. This copying process takes about 3 to 5 minutes. You can download the BIOS from the companies website.

Some motherboards have a flash recovery jumper that is used to restore the system. If your BIOS chip is electronically erasable, that is EEPROM, if the BIOS is not upgraded using the BIOS upgrade software, you can use it. Can upgrade.

How to reset BIOS

If you are having some problems booting your computer system, you can reset your settings to the default.

  • Press and hold the power button for 10 seconds, or until your system is fully Do not stop with.
  • Restart your computer.
  • Press the BIOS key of your computer.
  • Choose the “Restore Defaults” option
