How to set a password on the DOS interface and how to change the password on DOS

You're talking about the CMOS password that you need to start the machine, right? If you don't enter it correctly, you can't turn on the machine.

You need to enter the CMOS to set up, various motherboard chips are different, and the setting methods are different, but the principle is the same, first find the place to set the password, set the password, and then change a property item to enter the password every time you start the machine. Desktops are generally in the "advanced settings", and there are too many patterns in notebooks, so you need to find them yourself.

To remove the password, you can press enter directly where the password was set.

It is a CMOS password, which is 100 times more secure than the user login password brought by the system, but there is also a certain danger, that is, don't forget the password. There is a supervisor password in it, it seems to be under the factory restore (different models), after the enter password appears, enter the password and then press enter, then the confirm password appears, and then enter the same password again (note: the original intention of this item is to verify the password just entered, if the password entered twice is inconsistent, you will be asked to re-enter);

Does DOS have a password?

You're talking about BIOS, right?

There is a set password setting in the BIOS.

You can give it a try.

How to set a computer password in DOS.

Method 1: Take Award BIOS as an example, there are two menus in the CMOS configurator: "Set Supervisor Password" and "Set User Password".

This is the "Set Superuser Password" and "Set User Password" menus. The specific setting method is (the motherboard is different, the setting interface is different): press the del key to go to the page, see the set user password, click, enter the password you want to set, and then the system prompts you to enter it again, press the esc key, enter the advanced BIOS features, see that there is a password check below, press page up or page down to select system, and then exit the settings, Then select Save, then turn it on, and you'll find a heart-pounding prompt to enter your password.

Method 2: CMOS provides users with two types of password settings, namely supervisor user password. The password is set as follows:

1 Select "supervisor password" in the main interface, press the enter key, and the "enter password" will appear, 2 The password you enter cannot exceed 8 characters, the screen will not display the entered password, press the enter key when the input is completed.

3 At this time, you will be asked to confirm the password: "confirm password", enter the password you just entered to confirm, then press enter, and it is set.

If you need to delete your previous password, just select it and press Enter (don't enter any characters) and you'll be able to delete your previous password. The difference between the password of the superuser and the ordinary user is that when entering the CMOS, all options of the CMOS can be modified by entering the password of the superuser, while the ordinary user can only change the password of the ordinary user, and cannot modify other parameters in the CMOS

option) to system, enter that any of them can be turned on. If the computer has been set with a BIOS password, and then forgot the password, there is no way to enter the BIOS now, the password can enter the system, but not the BIOSWhat to do?

You enter in command-line mode.

Q70 and 71 are the two ports of CMOS, we can write some error data (such as etc.) behind them at will, and all settings in CMOS will be cleared, if it doesn't work, you might as well use a few more data to try.

Step 1 Start the computer and press the [del] button to enter the main BIOS settings interface.

Step 2 In the BIOS main menu, there are two options to set a password, they are "Set Supervisor Password" and "Set User Password".

Step 3 Select one of them and press enter, enter the password when the Enter Password dialog box appears. If you are setting this for the first time, enter the password should not exceed 8 characters, and note that this password is case-sensitive. When typing, the screen will not display the entered password, press the [Enter] key after entering.

Step 4 Immediately after that, the confirm password dialog box appears, enter the same password again (note: the original intention of this item is to verify the password just entered, if the password entered twice is inconsistent, you will be asked to re-enter it).

Step 5 Then in the BIOS main menu, select the "Advanced BIOS Features" item, select the "Security Option" item with the cursor key, and use the [Page Up Page Down] key on the keyboard to change the option to System.

Open the case, take out the button battery inside and discharge it to the CMOS, so that the boss password will be automatically canceled.

Each type of motherboard BIOS is different, and there is a prompt when you boot up, just go in and set it up. It is generally important to remember that laptops cannot be reset, and desktops are discharged to reset.

It's time to set the boss password! Boot press del into the boss setting, generally in the third item on the right.

Leave the password blank and cancel.
