Compute Module MFS2600KI User Guide
Comments:
The Thermal Throttling Mode chosen reflects whether the DIMMs have
Temperature Sensors (TSOD), and whether the chassis is an Intel
®
chassis for which thermal data
are available. Note that this is for thermal throttling only, independent of any controls imposed
for the purpose of power limiting.
DCLTT is the expected mode for the Intel
®
Compute Module MFS2600KI, which
has inlet and outlet air temperature sensors and TSOD. The firmware can update the
offset registers for closed loop during runtime, as BIOS sends the dynamic CLTT
offset temperature data.
SCLTT would be used with an OEM chassis and DIMMs with TSOD. The firmware
does not change the offset registers for closed loop during runtime, although the
Management Engine can do so. This is not suggested to use on the Intel
®
Compute
Module MFS2600KI.
SOLTT is intended for a system with UDIMMs which do not have TSOD. The
thermal control registers are configured during POST, and the firmware does not
change them.
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. For enabling Intel
®
TXT, see the
Processor
Configuration
screen.
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.
