Quiet Fan Idle Mode does not conflict with Fan PWM Offset (above) – they work in concert, with
Fan PWM Offset applied to fans in Quiet Fan Idle Mode just as when the fans are operating in
“normal mode”. A Fan PWM Offset of zero is necessary for fans to actually stop turning.
Security Screen (Tab)
The Security screen allows the user to enable and set the Administrator and User passwords and to
lock out the front panel buttons so they cannot be used. This screen also allows the user to enable
and activate the Trusted Platform Module (TPM) security settings on those boards that support
TPM.
Note that it is necessary to activate the TPM in order be able to enable Intel
®
Trusted Execution
Technology (TXT) on boards that support it. Changing the TPM state in Setup will require a Hard
Reset for the new state to become effective.
This BIOS supports (but does not require) “Strong Passwords” for security. The “Strong Password”
criteria for both Administrator and User passwords require that passwords be between 8 and 14
characters in length, and a password must contain at least one case-sensitive alphabetic character,
one numeric character, and one special character. A warning is given when a password is set which
does not meet the Strong Password criteria, but the password is accepted.
For further security, the BIOS optionally may require a Power on Password to be entered in early
POST in order to boot the system. When Power On Password is enabled, POST is halted soon after
power on while the BIOS queries for a Power On Password. Either the Administrator or the User
password may entered for a Power on Password.
To access this screen from the Main screen or other top-level “Tab” screen, press the right or left
arrow keys to traverse the tabs at the top of the Setup screen until the Security screen is selected.
