When Should I Boot To BIOS?

BIOS is an acronym for "Basic Input Output System" in English. After literal translation, the Chinese name is "Basic Input Output System". On IBM PC compatible systems, it is an industry standard firmware interface. ^[1] The word BIOS first appeared in the CP / M operating system in 1975. ^[2] BIOS is the first software loaded when a personal computer boots.

The term BIOS (Basic Input / Output System) was originally coined by Gary Kildall ^[3]

The BIOS setup program is stored in the BIOS chip.

Different BIOS have different ways to enter, usually in

BIOS is the basic hardware input and output program stored in ROM chip. CMOS is used to store BIOS settings and system time. RAM is generally integrated in the Southbridge.

Functionally, the BIOS is divided into three parts:

Self-test and initialization

This part is responsible for starting the computer. There are three parts:

There are three main types of motherboard BIOS on the market: Award BIOS, AMI BIOS, Phoenix BIOS, and Insyde BIOS.

Next-generation BIOS: UEFI BIOS

The BIOS that has been in the IT industry is about to be eliminated by UEFI ^[12] BIOS, and the new motherboard will popularize UEFI BIOS. MSI claims that the UEFI BIOS will replace the BIOS within three years. The UEFI BIOS stands for "Unified Extensible Firmware Interface", which is a standard describing in detail new types of interfaces. This interface is used for the operating system to automatically load from a pre-started operating environment onto an operating system, thereby simplifying the startup procedure and saving time.
