Full Form of BIOS

The full form of BIOS is the “Basic Input Output System”. BIOS is software built into a computer system. As we switch on the computer, it is the first program that is operated by the computer system. Typically this program is housed in Read-Only Memory (ROM) and is placed on the motherboard of the CPU. In modern computers, the BIOS stores the contents using flash memory.
Without BIOS it is impossible for a computer to start because it is the BIOS that loads the hard disk drivers and key parts of the operating system such as GPT, FAT, and MBR into the storage to allow the operating system to begin loading itself. The other names of system BIOS, are PS BIOS and ROM BIOS.

History and Operation of BIOS

We have covered the full form of BIOS and understood the definition of BIOS. Here we are going to see some of the basic operations of BIOS. BIOS first came into view on the CP or M software in 1975. Gary Kildall created the term BIOS obtained from the Basic Input and Output System. The major functions of BIOS are given below:-
  • BIOS’s primary function is to start opening and checking all elements of hardware that are linked to the computer system.
  • It is often used when the key elements of the software are transferred.
  • BIOS offers a means available for use that starts the software applications to be more straightforward and more usable by the users.
  • It also connects the operating system to the Screen, keypad, and other input or output devices together.
  • BIOS managed the energy management process and began to open register memory.
  • It checks and switches the drivers of the computer, and interferes with RAM handlers.
  • A consumer can adjust the settings for CD or DVD or BD drive, hard drive, and floppy drive.

Suppliers of BIOS

Here we are proving the list of primary companies that supply the BIOS. A list of the most common BIOS suppliers are,
  1. IBM
  2. Dell
  3. Gateway
  4. Insyde Software
  6. American Megatrends (AMI)
  7. Phoenix Technologies

Benefits of BIOS

  • The update handles compatibility problems.
  • For the user, it gives more command over his computer device.
  • Updating the BIOS will enhance the overall performance & processing of computers.

Limitations of BIOS

  1. BIOS routines are typically unorganized, so OSs have their hardware schedules and drivers managed in the latest period.
  2. BIOS often boots not in 32-bit or 64-bit safe mode but also in a 16-bit real way, and it isn’t always the fastest because of the type of chip used.

BIOS Setup

It is a configuration program that permits us to configure hardware settings. BIOS setup is also known as CMOS setup. BIOS or CMOS setup includes:
  1. Loading of the BIOS Setup Default
  2. Changing the booting order
  3. Creation or deletion of the BIOS Password
  4. Setting or Changing the Date and Time
  5. Changing Floppy Disc, Hard Drive, or CD/DVD Settings
  6. Check Memory Installed status
  7. Enabling or Disabling the Computer Logo
  8. Enabling or Disable the Quick POST
  9. Enable or Disable the CPU Internal Cache
  10. Enable or Disable the Caching of BIOS
  11. Change CPU Settings
  12. Change Memory Settings
  13. Change System Voltages
  14. Enable or Disable RAID
  15. Enable or Disable Onboard USB, Audio ports, and serial/ parallel Ports
  16. Enable or Disable Onboard Floppy Controller
  17. Enable or Disable ACPI
  18. Change the Boot Up NumLock Status
  19. Change the Advanced Configuration and Power Interface (ACPI) Type
  20. Change the Power Button Function
  21. Change Power-on Settings
  22. Change Which Display is Initialized First on Multi-Display Setups
  23. Reset Extended System Configuration Data (ESCD)
  24. Enable or Disable BIOS Control of System Resources
  25. Change and view Fan Speed Settings
  26. View CPU and System Temperatures
  27. View System Voltages
