What is BIOS? what’s the effect?

BIOS, or Basic Input Output System, is the first software that runs when a computer starts. It is responsible for initializing and testing computer hardware, and loading the operating system.

BIOS settings allow users to configure hardware options such as boot sequence, system time and date, etc., and are crucial for system maintenance and troubleshooting.

 How to enter BIOS for common computer brands


When starting the computer, you need to quickly press the `F2` key to enter the BIOS setup interface.


During the boot process, press the `Esc` key and then select F10 in the menu that appears to enter the BIOS.


For Lenovo computers, press the `Enter` key when starting up, and then select BIOS settings to enter.


Similar to Dell, you can enter the BIOS by pressing the `F2` key during startup.


On boot, press the `Del` key and you will be booted to BIOS setup.


MSI computers also use the `Del` key to enter BIOS setup.


Apple computers use EFI firmware settings, which are slightly different from BIOS:

– For Macs with Intel chips, press the `Option` key when starting.

– For Macs with Apple Silicon chips, press and hold `Command + Option + R` immediately upon startup.

 other brands

For other brands or assembled computers, the keys to enter the BIOS may include `F1`, `F10`, `Del`, `Esc`, etc. The specific keys depend on the motherboard manufacturer.

 General steps:

1. Shut down the computer: Make sure the computer is completely shut down.

2. Continuous tapping: When turning on the computer, when any logo or text appears, immediately tap the corresponding BIOS entry key continuously.

3. Try again: If you miss the opportunity, the computer will start normally and you will need to restart and try again.


– Power connection: Before entering the BIOS, make sure the computer is connected to power to avoid data loss or damage.

– Change with caution: Be careful when changing settings in the BIOS. Improper settings may cause startup problems.

After completing the BIOS setup, you can adjust the hardware configuration, such as changing the boot sequence, setting the system time and date, adjusting security options, etc.

If you need to upgrade or reset the BIOS, follow the manufacturer’s instructions to avoid damage to your computer.
