If you are running Dell servers, it is recommended to enable BIOS password. This is will prevent accidental changes done to Dell BIOS settings by others who get physical access to the server.
You can setup two different types of passwords in Dell BIOS:
System Password: This will be prompted before the system can boot up, and load the operating system.
Setup password: The system will prompt for this password only when you are trying to access the BIOS settings.
Depending on your situation, it might be a good idea to enable both the system and setup password at the BIOS level. I recommend that you at least enable BIOS password.
Press F2 for System Setup
When the Dell server is booting up, press F2 to start system setup, from where you can change Dell BIOS settings.
BIOS System Security
From the Dell BIOS main menu, scroll down to “System Security” and press enter.
Password Not Enabled
From here, you can see that both the System and Setup password is not enabled by default.
Enable System Password (and Setup Password)
Scroll to “System Password” and press enter, which will prompt you to enter the password that you like to set for the system. Please understand that if you set this password, you have to enter this password everytime you start the system. Do the same thing for Setup Password.
Don’t forget this bios password. If you forget, then you have go through the painful process of resetting the Dell BIOS password.
Password is Enabled
Once you’ve enabled both the password, from the “System Security” menu, you’ll see that that both system and setup password is enabled as shown below.

System Password Prompt (During Startup)
From now-onwards, anytime you start the system, it will not load the operating system, unless you specify the system password as shown below.
Setup Password Prompt (To Access BIOS)
If you press F2, to get to the BIOS, it will prompt for the setup password as shown below. If you don’t enter a valid password here, you cannot access the Dell BIOS settings anymore.
