Table 5. Software Security Features (continued) Feature Description Control access to using the SSU: set administrator password To control access to setting or changing the system configuration, set an administrator password and enable it through Setup or the SSU. If both the administrator and user passwords are enabled, either can be used to boot the system or enable the keyboard and/or mouse, but only the administrator password allows changes to Setup and the SSU. Once set, passwords can be disabled by setting the password to a null string or by changing the Clear Password jumper. See "Security Menu," page 41; or, to change a jumper, see "Baseboard Jumpers," page 151. Control access to the system other than SSU: set user password Boot without keyboard Specify the boot sequence To control access to using the system, set a user password and enable Password on Boot through Setup or the SSU. Once set, passwords can be disabled by setting the password to a null string or by changing the Clear Password jumper. See "Security Menu," page 41; or, to change a jumper, see "Baseboard Jumpers," page 151. The system can boot with or without a keyboard. Before the system boots during POST, BIOS automatically detects and tests the keyboard, if present, and displays a message. No entry exists in the SSU for enabling or disabling a keyboard. Do not plug in a keyboard while power is applied to the system. The sequence you specify in the Boot Device Priority Submenu (see page 44) of the SSU's Boot Menu determines the boot order. If secure mode is enabled (user password is set), you will be prompted for a password before the system boots fully. If secure mode is enabled and the "Secure Mode Boot" option is also enabled, the system boots fully but requires a password before accepting any keyboard or mouse input. 30
