The Intel® Management Engine BIOS Extension (MEBx) provides platform-level configuration options for you to configure the behavior of
Management Engine (ME) platform. Options include enabling and disabling individual features and setting power
configurations.
This section provides details about MEBx configuration options and constraints, if any.
All the ME Configuration setting changes are not cached in MEBx. They are
note committed to ME
nonvolatile memory (NVM)
until you exit MEBx. Hence, if MEBx crashes, the changes made until that point are NOT
going to be committed to ME NVM.
NOTE: Briscoe AMT is shipped in enterprise mode as default.
Accessing MEBx Configuration User Interface
The MEBx configuration user interface can be accessed on a computer through the following steps:
Turn on (or restart) your computer.
When the blue DELL™ logo appears, press <Ctrl><p> immediately.
If you wait too long and the operating system logo appears, continue to wait until you see the Microsoft® Windows®
operating system desktop. Then shut down your computer and try again.
Type the ME password. Press <Enter>.
The MEBx screen appears as shown below.
The main menu presents three function selections:
Intel ME Configuration
Intel AMT Configuration
Change Intel ME Password
The Intel ME Configuration and Intel AMT Configuration menus are discussed
in the following
sections. First, you must change the password before you can proceed through these menus.
Changing the Intel ME Password
The default password is admin and is the same on all newly deployed platforms. You must change the default password before
changing any feature configuration options.
The new password must include the following elements:
Eight characters
One uppercase letter
One lowercase letter
A number
A special (nonalphanumeric) character, such as !, $, or ; excluding the :, ", and , characters.)
The underscore ( _ ) and spacebar are valid password characters but do NOT add to the password complexity.
Configuring the Intel®
Management Engine (ME)
To reach the Intel® Management Engine (ME) Platform Configuration
page, follow these steps:
Under the Management Engine BIOS Extension (MEBx) main menu, select ME
Configuration. Press <Enter>.
The following message appears:
System resets after configuration changes. Continue: (Y/N)
Press <Y>.
The ME Platform Configuration page opens. This page allows
you to configure the specific functions of the ME such as features, power
options, and so on. Below are quick links to the various sections.
When the ME State Control option is selected on the ME
Platform Configuration menu, the ME State Control
menu appears. You can disable ME to isolate the ME computer from main platform
until the end of the debugging process.
When enabled, the ME State Control option lets you disable
ME to isolate the ME computer from the main platform while debugging a field
malfunction. The table below illustrates the details of the options.
ME Platform State Control
Option
Description
Enabled
Enable the Management Engine on the platform
Disabled
Disable the Management Engine on the platform
In fact, the ME is not really disabled with the Disabled
option. Instead, it is paused at the very early stage of its booting so the
computer has no traffic originating from the ME on any of its busses, ensuring
that an you can debug a computer problem without worrying about any role the
ME might have played in it.
Intel ME Firmware Local Update
This option on the ME Platform Configuration menu sets the
policy for allowing the MEBx to be updated locally. The default setting is Always
Open. The other settings available are Never Open
and Restricted.
To assist with the manufacturing process as well as OEM-specific in-field
firmware update processes, ME firmware provides an OEM- configurable
capability that leaves the local firmware update channel always open no matter
what value you select for the ME Firmware Local Update
option.
The Always Open option allows OEMs to use the ME firmware
local update channel to update the ME firmware without going through MEBx
every time. If you select Always Open, the ME FW
Local Update option does not appear under the ME configuration menu.
The table below illustrates the detail of the options.
ME Firmware Local Update Option
Option
Description
Always Open
The ME firmware local update channel is always enabled. A boot cycle
does not change enabled to disabled. The ME FW Local Update
option can be ignored.
Never
The ME firmware local update channel is controlled by the ME
FW Local Update option, which can be enabled or disabled. A
boot cycle changes enabled to disabled.
Restricted
The ME firmware local update channel is always enabled only if Intel
AMT is in un-provision state. A boot cycle does not change enabled to
disabled.
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.
Many OEMs' platforms supply a BIOS setup option to enable or disable the
integrated LAN controller. In an ME operating system with AMT or ASF (Alert Standard
Format) capabilities, the LAN controller is shared between the ME and host and
must be enabled for AMT to work correctly. Disabling the controller may
unintentionally affect the ME subsystem functionality. Therefore, you should
not disable the LAN controller as long as the ME uses it to provide AMT or ASF.
However, if the platform's integrated LAN controller BIOS option is set to None,
then the LAN Controller option on the ME Platform
Configuration menu has Enabled and Disabled
options.
When you select the LAN Controller option on the ME
Platform Configuration menu when the ME feature (Intel AMT or Intel
QST) is selected, the following message displays: Please set
Manageability Feature to None before changing this option. For the ME
platform client, the default LAN Controller setting is
Enabled.
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.
ASF — Alert Standard Format. ASF is a standardized
corporate assets management technology. The Intel ICH9 platform supports
ASF specification 2.0.
Intel AMT — Intel Active Management Technology. Intel
AMT is an improved corporate assets management technology. Intel ICH9
platform supports Intel AMT 2.6.
The table below explains these options.
Management Feature Select Option
Option
Description
None
Manageability Feature is not selected
Intel AMT

ASF
ASF manageability feature is selected
When you change the option from Intel AMT to None,
a warning that Intel AMT un-provisions automatically if you accept the change
appears.
The None option has no manageability feature provided by
the ME computer. In this case, the firmware is loaded (that is, ME is still
enabled) but the management applications remain disabled.
Intel ME Power Control
The ME Power Control menu configures the ME platform
power-related options. It contains the following configuration selection.
ME On in Host Sleep States
When the ME ON in Host Sleep States option is selected on
the ME Power Control menu, the ME in Host Sleep
States menu loads.
The power package selected determines when the ME is turned ON. The default
power package turns off the ME in all Sx (S3/S4/S5) states.
The end user administrator can choose which power package is used depending
on computer usage. The power package selection page can be seen above.

power package selected does NOT indicate OFF After Power Loss
Intel ME powers the computer on (S0) briefly, then turn the computer off (S5).
Configuring Your Computer to Support Intel AMT Management Features
After you completely configure the Intel® Management Engine (ME) feature, you must reboot before configuring the Intel AMT for
a clean boot. The image below shows the Intel AMT configuration menu after a user selects the Intel AMT
Configuration option from the Management Engine BIOS Extension (MEBx) main menu. This feature allows you to
configure an Intel AMT capable computer to support the Intel AMT management features.
You need to have a basic understanding of networking and computer technology terms, such as TCP/IP, DHCP, VLAN, IDE, DNS, subnet
mask, default gateway, and domain name. Explaining these terms is beyond the scope of this document.
The Intel AMT Configuration page contains the user-configurable options listed below.
A hostname can be assigned to the Intel AMT capable computer. This is the host name of the Intel AMT-enabled computer. If Intel AMT is
set to DHCP, the host name MUST be identical to the operating system machine name.
TCP/IP
Allows you to change the following TCP/IP configuration of Intel AMT.
Network interface – ENABLE** / DISABLED
If the network interface is disabled, all the TCP/IP settings are no longer needed.
DHCP Mode – ENABLE** / DISABLED
If DHCP Mode is enabled, TCP/IP settings are configured by a DHCP server.
If DHCP mode is disabled, the following static TCP/IP settings are required for Intel AMT. If a computer is in static mode it
needs a separate MAC address for the Intel Management Engine. This extra MAC address is often called the Manageability MAC (MNGMAC)
address. Without a separate Manageability MAC address, the computer can NOT be set to static mode.
IP address – Internet address of the Intel Management Engine.
Subnet mask – The subnet mask used to determine what subnet IP address belongs to.
Default Gateway address – The default gateway of the Intel Management Engine.
Preferred DNS address – Preferred domain name server address.
Alternate DNS address – Alternate domain name server address.
Domain name – Domain name of the Intel Management Engine.
Provisioning Server
Sets the IP address and port number (065535) for an Intel AMT provisioning
server. This configuration only appears for Enterprise Provision Model.
Provision Model
The following provisioning models are available:
Compatibility Mode – Intel AMT 2.6** / Intel AMT 1.0
Compatibility mode allows user to switch between Intel AMT 2.6 and Intel AMT 1.0.
Provisioning Mode – Enterprise** / Small Business
This allows you to select between small business and enterprise mode. Enterprise mode may have different security settings
than small business mode. Because of the different security settings, each of these modes requires a different process to complete
the setup and configuration process.
Set PID and PPS
Setting or deleting the PID/PPS causes a partial un-provision
if the setup and configuration is "In-process".
Set PID and PPS – Sets the PID and PPS. Enter the PID and PPS in the dash format. (Ex. PID:
1234-ABCD ; PPS: 1234-ABCD-1234-ABCD-1234-ABCD-1234-ABCD) Note - A PPS value of '0000-0000-0000-0000-0000-0000-0000-0000' does
not change the setup configuration state. If this value is used the setup and configuration state stays as "Not-started."
Un-Provision
The Un-Provision option allows you to reset the Intel AMT configuration to factory defaults. There are three
types of un-provision:
Partial Un-provision – This option resets all of the Intel AMT settings to their default values but leaves
the PID/PPS. The MEBx password remains untouched.
Full Un-provision – This option resets all of the Intel AMT settings to their default values. If a PID/PPS
value is present, both values are lost. The MEBx password remains untouched.
CMOS clear – This un-provision option is not available in the MEBx. This option clears all values to their
default values. If a PID/PPS is present, both values are lost. The MEBx password resets to the default value (admin). To
invoke this option, you need to clear the CMOS (i.e. system board
jumper).
This option allows you to enable/disable secure firmware updates. Secure firmware update requires an administrator user name and
password. If the administrator user name and password are not supplied, the firmware cannot be updated.
When the secure firmware update feature is enabled, you are able to update the firmware using the secure method.
Secure firmware updates pass through the LMS driver.
Set PRTC
Enter PRTC in GMT (UTC) format (YYYY:MM:DD:HH:MM:SS). Valid date range is 1/1/2004 – 1/4/2021. Setting PRTC value is used for
virtually maintaining PRTC during power off (G3) state. This configuration is only displayed for the Enterprise Provision Model.
Idle Timeout
Use this setting to define the ME WoL idle timeout. When this timer expires,
the ME enters a low-power state. This timeout takes effect only when one of the
ME WoL power policies is selected. Enter the value
in minutes.
