BIOS stands for Basic Input/Output System. It’s a code that comes with the motherboard and not with the operating system. It runs prior to the operating system to ensure that required hardware components are functional. This independent code, also known as firmware, activates the chipset, processor and cache, RAM, hard drive/s, graphics card, audio card, and other expansion cards before operating system boots up.

Once everything is in place, BIOS then allows the operating system to take control of your computer.

That said, BIOS has two important functions:

  1. to ensure that basic necessary hardware requirements are met, and
  2. To help a user troubleshoot basic hardware issues by reporting error codes

Most modern BIOS allows a user to make some hardware adjustments including the ones below:

  1. Date and Time
  2. Boot Sequence
  3. Advanced Boot Settings
  4. System, Admin and Hard Drive passwords
  5. Restore the BIOS settings to factory defaults
  6. Turning ON or OFF modular add-on devices
  7. Adjusting LCD brightness (notebook computers only)
  8. Adjusting the number of cores the processor is using and the speed they are functioning

As part of your computer’s suite of diagnostic tools, BIOS can also report on basic hardware functionality such as RAM, processor (CPU) information, graphics card, audio card, hard drive, monitor, AC adapter (for Notebooks only), battery charge and health (for Notebooks only).

How do you update your Dell BIOS?

As a piece of code, BIOS, just like the operating system, can sometimes need an update to fix known bugs and to implement enhancements to basic hardware functions. If you are not experiencing troubles with your machine though, we won’t recommend that you attempt a BIOS update.
