When a BIOS User account has been established by the initial setup of HP Protective Tools, you can establish a BIOS Administrator account using BiosConfigUtility.exe to gain administrative access to the BIOS.
To set up a BIOS Administrator account, you must set a BIOS Administrator password using HP BIOS Configuration Utility (BCU). As the BIOS Administrator, you can reset the passwords for other accounts or use Reset BIOS Security to Defaults to remove all accounts and security information in the TPM.
