This article mainly introduces the solution of entering the bios interface when the computer is turned on, which is very detailed and has a certain reference value. Interested friends must finish reading it!

Computer boot to enter the bios interface solutions: 1, the purchase of motherboard battery replacement, and reset the correct parameters in the BIOS interface; 2, press the DEL key to enter BIOS, and then press F9 to load predefined parameters; 3, repair the hard disk master boot record or reinstall the system or replace the hard disk.

1. Battery failure: you can check whether the system time is accurate in the BIOS interface. If it is not accurate, it can be judged that the motherboard battery fails, causing the computer to call the BIOS default parameters. If it does not match the local hardware environment, the computer cannot be started normally. You can purchase the motherboard battery to replace, then boot and press the DEL key (notebook is F2 or other specified hotkeys) to enter the BIOS interface, and reset the correct parameters, and finally press F10 to save and exit restart.

2. Configuration error: this will also happen because the manual configuration of BIOS parameters does not match the local hardware environment. If you are not sure how to set the parameters, in general, you can press F1 key to skip the non-fatal error and start the computer directly according to the white word on the black screen, or press Del key to enter BIOS, then press F9 to load predefined parameters or select Load Optimized Defaults (load high performance default) or Load Fail-Safe Defaults (load fail-safe default)

3. Hardware failure: if the above operations are not effective, it means that there is a problem with the hardware. Generally, the contact between the memory and the hard disk is bad or the hard disk master boot record is damaged, and the memory or hard disk needs to be reseated. Or repair the hard disk master boot record or reinstall the system or replace the hard disk.

BIOS is an acronym for "Basic Input Output System". After literal translation, the Chinese name is "basic input and output system". In fact, it is a group of programs solidified on a ROM chip on the motherboard in the computer. It stores the computer's most important basic input and output programs, post-boot self-test programs and system self-start programs. It can read and write specific information of system settings from CMOS. Its main function is to provide the lowest and most direct hardware setting and control for the computer.

Related introduction:

Functionally, BIOS is divided into three parts:

Self-test and initialization

This part is responsible for starting the computer, which has three parts:

The first part is used to detect the hardware when the computer is just powered on, also known as Power On Self Test (POST). The function is to check whether the computer is in good condition. Usually, the complete POST self-test will include testing of CPU,640K basic memory, more than 1m extended memory, ROM, motherboard, CMOS memory, serial and parallel ports, display cards, soft and hard subsystems and keyboards. Once problems are found in the self-test. The system will give a prompt or whistle warning.

If an error is found in the self-test, it will be dealt with according to two situations: for a serious fault (fatal fault), the machine will be stopped, and no hint or signal can be given because various initialization operations have not been completed; for non-serious faults, prompt or sound alarm signals will be given, waiting for the user to deal with.

The second part is initialization, including the creation of interrupt vectors, setting registers, initialization and detection of some external devices, etc., of which a very important part is the BIOS setting, mainly some parameters of the hardware settings, when the computer starts, these parameters will be read and compared with the actual hardware settings, if not consistent, it will affect the startup of the system.

The third part is the bootstrap program, which is used to boot DOS or other operating systems. BIOS first reads the boot record from the start sector of the floppy disk or hard disk, and if it is not found, it will show that there is no boot device on the monitor. If it finds the boot record, it will transfer the control of the computer to the boot record, and the operating system will be loaded into the computer by the boot record. After the computer starts successfully, this part of the task of BIOS will be completed.
