What are BIOS settings?

BIOS identifies, configures, tests and connects computer hardware to the OS immediately after a computer is turned on. The combination of these steps is called the boot process. These tasks are each carried out by BIOS’ four main functions: Power-on self-test (POST).

Are BIOS settings important?

The BIOS interface allows you to tweak your machine’s hardware outside the operating system. Overclockers spend a lot of time in the BIOS adjusting voltage and CPU frequency multipliers. Even if you’re not an overclocker, significant system fixes often require BIOS access.

What happens when you set BIOS?

It performs a POST (power-on self-test), initializes your hardware, and passes control to the boot loader on a connected device. This then boots your operating system—Windows, Linux, or whatever else you’re using. All of this is automatic, but the BIOS also has a setup screen, which you can access.

A BIOS attack does not require any vulnerability on the target system — once an attacker gains administrative-level privileges, he can flash the BIOS over the Internet with malware-laden firmware.

What are common BIOS options?

Common options include: System Time/Date – Set the system time and date. Boot Sequence – The order that BIOS will try to load the operating system. Plug and Play – A standard for auto-detecting connected devices; should be set to “Yes” if your computer and operating system both support it.

Does BIOS setting affect performance?

You can configure BIOS settings to get more productivity out of servers, but some high-performance settings could increase power consumption or put reliability at risk.
