I’ve recently had a problem on some new servers where a BIOS Admin Password had been set by accident, HPE provide this as a solution on their forums: https://community.hpe.com/t5/proliant-servers-ml-dl-sl/how-do-i-disable-the-bios-admin-password-on-a-gen10-dl360/m-p/7166755#M178013
However the Gen10Plus (+) servers appear to be a bit different, upon entering the forward slash “/” on the end of the password to remove it, you get a warning saying “/” is an invalid character and the process does not work.
Instead the process was much more simple:
- When you get into the System Utilities menu (Boot –> F9 –> System Utilities –> System Configuration –> BIOS Platform Configuration (RBSU) –> Server Security), you have to click in the Set Admin Password box and press ENTER to input a password.
- Enter your current password, then to clear/delete/remove the existing password, just hit ENTER, i.e. leave the box blank. You’ll be informed the password has been changed.
- Save and exit, reboot, now the next time you try to get into the RBSU you’ll not see the password prompt.
