For additional security, Dell Technologies recommends keeping the Firmware Device Tamper Detection option enabled. Clear Firmware Device Tamper Detection Enables or disables the feature to clear the event and allow booting when a tamper detection event is logged. By default, the Clear Firmware Device Tamper Detection option is disabled. Table 37. BIOS Setup options-Passwords menu Passwords Admin Password The Administrator Password prevents unauthorized access to the BIOS Setup options. Once the administrator password is set, the BIOS setup options can only be modified after providing the correct password. The following rules and dependencies apply to the Administrator Password - ● The administrator password cannot be set if computer and/or internal hard drive passwords are previously set. ● The administrator password can be used in place of the computer and/or internal hard drive passwords. ● When set, the administrator password must be provided during a firmware update. ● Clearing the administrator password also clears the computer password (if set).
