What is BIOS

The full name of BIOS is Basic Input Output System (Basic Input Output System), which is a special computer program that is solidified on the motherboard by the motherboard manufacturer. It will detect the hardware when the computer is turned on, run the self-check program, and then start to find the operating system and boot to the operating system. Therefore, if you need to modify the computer motherboard settings, you need to enter the BIOS to modify.

How to enter the BIOS

It depends on the motherboard. Different motherboard manufacturers set different ways. When the motherboard manufacturer’s logo appears just after booting up, there will usually be a line of small characters below to indicate which key to press to enter the BIOS. At this time, just press the corresponding key. For example, when I enter the BIOS of the Acer laptop I am using, I need to press F2. Some notebooks will have a special physical button to restart and enter the BIOS, usually on the side of the fuselage, you need to use a needle to poke, the machine will automatically enter the BIOS.

BIOS option description

After entering the BIOS, an English interface usually appears. This interface usually has several tabs, and different configurations can be made by clicking on the tabs.

Information tab

There is nothing to configure in this place, mainly to display the current computer hardware information. For example, CPU type, main frequency, hard disk name, BIOS version, manufacturer information, etc. The information displayed by the BIOS of my laptop is like this:

Main tab

The main options of some motherboards are shown here. The first is the system date and time, which can be modified. Then there is the installed memory and video memory, which cannot be modified. The following are the options that may need to be set, enable is to enable, and disable is not to enable:

1.Network Boot: Whether to enable network boot. Individual users can turn off this option. Network startup is available to enterprise users after configuring Windows Servers.

2.F12 Boot Menu: Whether to open F12 advanced startup options. After enabling this option, you can press F12 at boot time to open the advanced startup options. It is recommended to turn it on.

3.D2D Recovery: The full name is disk-to-disk recovery, which is a backup and recovery function provided by some manufacturers, and requires disks to provide additional partitions to support backups. If the entire disk has been formatted during the reinstallation of the system, then this function should not be available.

4. Wake on LAN: Wake on LAN function, need the support of network card. After opening, you can start the computer through the network. Interested students can configure and use WOL on Baidu.

5.SATA Mode: SATA mode, there are Legacy and AHCI two. When installing XP system, Legacy mode is required to install. Now when installing the latest Win10 and other systems, changing to the AHCI mode is better and can improve the performance of the hard disk.

6.Intel Virualization: Intel Virtualization Technology, it is recommended to enable it. After turning on this option, the CPU can simulate multiple CPU operations. After that, you can run 64-bit virtual machines in virtual machine software such as VMWare.

Security tab

Here you can set various passwords, such as master password, user password, hard disk password, startup password and so on. It is not recommended to set a password here, unless it is when you want to prevent your children from playing computers and other destinations. If you have set a password, please remember the password, otherwise you cannot perform any operations. Use with caution!

Startup tab

This is probably the most used and most need to talk about. Because if you want to reinstall the system, the settings are restarted from the installation media, you must make this setting. The description of these settings is as follows:

1.Boot Mode: Boot mode, there are two kinds of UEFI and BIOS. If you need to expand to XP and other operating systems, you need to set the hard disk mode to Legacy in front, and set the boot mode to BIOS here. If you want to install a relatively new operating system such as Win8 and Win10, it is best to use UEFI, which can improve the overall system boot speed and security.

2.Security Boot: secure boot. If you only use the Windows operating system and do not plan to use Linux, this option is enabled by default. If there is a need to install Linux, it is best to turn off this option, otherwise it will not be able to boot.

The following is the specific modification of the startup item. If you insert the completed system boot disk into the computer and restart to the BIOS, a corresponding option will appear here. Then set it to the first boot sequence, save the BIOS settings, and then restart to install the system. After the installation is complete, remember to re-enter here to reset the hard disk of the installed system to the first boot. If Windows is installed in UEFI mode, a Windows Boot Manager will appear. If there are multiple Windows installed, Windows Boot Manager will manage these multiple Windows operating systems by the way.

Finally, talk about how to modify the startup item. Generally, F5 is down, F6 is up, and the cursor keys select the startup item to be modified. After the modification is completed, press F10 to save and exit. The settings may be different between different motherboards. In fact, the specific operation method is explained under the BIOS, but it is only in English.

Close the tab

Here I don’t have a screenshot. In fact, it has two options, save and exit and exit without saving. After configuring the BIOS, select Save and exit, and it will automatically restart. Then install the selected boot sequence to find the operating system to boot. If you understand it, you will find that the BIOS is actually not complicated, as long as you understand how to set it up, it’s easy.

Finally

If it is the current new version of the motherboard, it already supports UEFI. Such a motherboard will display a graphical operation interface when opening the BIOS, and support mouse and keyboard operations, and generally have Chinese language at the same time, so it is very convenient to set up.
