Dell OptiPlex 755 - Manual (Page 6)

Always Open qualifies the override counter and allows local ME firmware updates. The override counter is a value set in the factory that, by default, allows
local ME firmware updates. The Never Open and Restricted options disqualify the override counter and do not allow local ME firmware updates unless
explicitly permitted with the Intel ME Firmware Local Update option. Selecting Never Open or Restricted adds the Intel ME Firmware Local Update option,
which can be set to Enable or Disable. By default it is disabled.
Intel ME Features Control
The ME Features Control menu contains the following configuration selection.
Manageability Feature Selection
When you select the Manageability Feature Selection option on the ME Features Control menu, the ME Manageability Feature menu appears.
You can use this option to determine which manageability feature is enabled.
l ASF — Alert Standard Format. ASF is a standardized corporate assets management technology. The Intel ICH9 platform supports ASF specification 2.0.
l Intel AMT — Intel Active Management Technology. Intel AMT is an improved corporate assets management technology. Intel ICH9 platform supports
Intel AMT 3.0.
The table below explains these options.
When you change the option from Intel AMT to None, a warning that Intel AMT un-provisions automatically if you accept the change appears.

management applications remain disabled.
