Essential Input or Output System, or BIOS, is sometimes known as System Setup. Unified Extensible Firmware Interface is standard on contemporary Dell PCs (UEFI). On a tiny memory chip located on the system board or motherboard of the computer, BIOS or UEFI is firmware. It interfaces between the operating system and the computer's hardware.

The BIOS or UEFI of the computer turns on all the fundamental hardware necessary to boot the operating system, including but not limited to:

  • Processor and cache on a chip

  • RAM, or system memory

  • controllers for audio and video

  • Typewriter and mouse

  • Internal hard discs

  • network managers

  • cards for internal expansion

On Dell PCs, you can access the BIOS or System Setup by:

During starting, at the Dell logo screen, repeatedly press the F2 key.

Alternately, at the Dell logo startup screen, press the F12 key repeatedly and choose BIOS Setup or System Setup from the menu.

NOTE: Different Dell machines may have a different BIOS or UEFI interface. Consult the user manual for your Dell computer to find out how to access the BIOS.

The BIOS or UEFI interface is intended for experienced computer users only. By altering these settings, you risk losing data, the computer failing its power-on self-test (POST), and the operating system not launching.

How To Update The BIOS On A Dell Computer

According to Dell, the BIOS should be updated as part of your regular update cycle. Updates to the BIOS can frequently add features, address bugs, or do both.

Additionally, security upgrades and improved stability are provided by BIOS updates.

Dell offers a simple self-installing BIOS update application. Additionally, Windows Update is used to distribute crucial BIOS updates.
