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 to continue the boot process. When the CMOS prompt appears, press the PAUSE button at any time to view it.

If you press DEL and do not respond, press F2 to enter, except IBM’s is to press F1! Others should be F2 or DEL, but some of the cards are entered by others. Some need to press “CTRL” + “S”. Some laptops press “F2” (such as ASUS), while IBM computers press “F12”, so look at your computer~

Computer cmos settings

CMOS is a readable and writable chip on the motherboard of the microcomputer, which is used to save the current system hardware configuration and user settings for certain parameters. There are three basic ways to enter the CMOS settings:

(1) Press the hotkey when booting: Press the specific key combination to enter the setting when booting. The hotkeys of different types of machines are different, some will give a prompt on the screen, for example, press DEL, press CTRL+ALT+ESC Combination keys, etc.

(2) Software provided by the system: Many motherboards now provide programs for managing system setting information under DOS, and Windows 95 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” button to enter the CMOS setting 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.
