How does the computer enter cmos? Set cmos method

Most computers
Enter cmos by pressing the “F2” button at boot or boot, but some brands of
computers
enter the cmos method are different, and some settings are also Not quite the same, here is the study of Xiaobian together to learn computer
enter cmos, set cmos method, I hope to help you!

Computer into cmos, set cmos method

After the power is turned on, when the display shows a signal, press the PAUSE button on the keyboard, and carefully check the information about entering the CMOS in the display message. If it does not appear, press the ENTER button. Continue the boot process, and when the CMOS prompt appears, press the PAUSE button at any time, and you can view it.

If you press DEL and do not respond, press F2 to enter, except for IBM, press F1! Others should be F2 or DEL, but some of the cards are based on other entry

Some need to press "CTRL" + "S", while the notebook computer is based on "F2" (such as ASUS), IBM computer Yes, press "F12", so look at your computer~

CMOS is a readable and writable chip on the motherboard of the microcomputer. Used to save the current configuration of the system hardware and user settings of certain parameters. There are three basic ways to enter the CMOS settings: (1) Press the hotkey at boot time: press the specific key combination to enter the setup at boot time. The hotkeys of different types of machines are different, some will give a prompt on the screen, for example press DEL Key, press CTRL+ALT+ESC, etc. (2) Software provided by the system: Many motherboards now provide programs for managing system setting information under DOS, and Windows
95 already includes functions such as energy saving protection and power management. 3) CMOS application software: Some applications (such as QAPLUS) provide CMOS read, write, and modify functions, through which some basic system settings can be modified.

After turning on the computer or restarting the computer, when the screen displays “Waiting……”, press the “Del” key to enter the CMOS settings interface. It should be noted that if you press too late, the computer will start the system, and only restart the computer. You can press and hold the Delete key immediately after booting until you enter CMOS. After entering, you can use the arrow keys to move the cursor to select the option on the CMOS setting interface, then press Enter to enter the sub-menu, use the ESC key to return to the parent menu, use the PAGE UP and PAGE DOWN keys to select specific options, the F10 key to retain and exit BIOS settings.
