Return to Default (Un-Provisioning)
Firmware Flash
Serial-Over-LAN (SOL) and IDE Redirection (IDE-R)
This section describes a few basic troubleshooting steps to follow if problems are experienced with the Intel ® AMT configuration.
Return to Default (Un-Provisioning)
Return to default is also known as un-provisioning. An Intel AMT setup and configured computer can be un-provisioned using the Intel AMT Configuration
screen and the Un-Provision option.
Follow the steps below to un-provision a computer:
1. Select Un-Provision and then select Full Un-provision.
Full un-provisioning is available for SMB Mode provisioned computers. This option returns all Intel AMT configuration settings to factory defaults and does
NOT reset ME configuration settings or passwords. Full and partial un-provisioning is available for Enterprise Mode provisioned computers. Partial un-
provisioning returns all Intel AMT configuration settings to factory defaults with the exception of the PID and PPS. Partial un-provisioning does NOT reset
ME configuration settings or passwords.
An un-provisioning message displays after about 1 minute. After un-provisioning completes, control is passed back to the Intel AMT Configuration screen.
Provisioning Server, Set PID and PPS, and Set PRTC options are available again because the computer is set to the default Enterprise Mode.
2. Select Return to previous menu.
3. Select Exit and then press <y>. The computer restarts.
Full Return to Factory Defaults
All Intel AMT settings can be returned to factory default by clearing the CMOS (via the jumper or CMOS battery). This includes resetting the password to the
default password of
admin . However, settings in the ME, such as the ME Power Settings, are not reset. These settings must be manually reset to for the
computer to be in a true factory-default state. The table below lists the default MEBx settings. The client cannot be remotely managed until it is set up and
configured again.
Firmware Flash
Flash the firmware to upgrade to newer versions of Intel AMT. The firmware flash is built into the BIOS flash utility and therefore flashed automatically when
the BIOS is flashed. The automatic flash feature can be disabled by selecting Disabled under the Secure Firmware Update setting in the
MEBx interface . If
this setting is disabled, a firmware error message appears when flashing the BIOS.
The firmware CANNOT be flashed to an older version or to the current version installed. The firmware flash is available on the support.dell.com site for
download.
Serial-Over-LAN (SOL) and IDE Redirection (IDE-R)
If you cannot use IDE-R and SOL, follow these steps:
1. At the initial boot screen, press <Ctrl><p> to enter the MEBx screens.
2. A prompt for the password appears. Enter the new Intel ME password.
3. Select Intel AMT Configuration.
4. Press <Enter>.
