Checking Whether Intel AMT Is Enabled

Before proceeding with Intel AMT setup, do the following:

1.  Invoke the STATE_INDEPENDENCE_IsChangeToAMTEnabled command to check whether the Intel AMT firmware supports the new Intel AMT enabling mechanism.

       * If Intel AMT does not support the new enabling mechanism OR Intel AMT is enabled, continue the Host-Based Setup and Configuration provisioning flow. Do not perform the rest of the steps on this page.

       *  If the new enabling mechanism is supported AND Intel AMT is disabled, invoke the MHC_SetAmtOperationalState command to enable Intel AMT.

2.  Initiate an IP refresh flow as follows:

       a. Initiate an OS DHCP refresh.

       b. Check whether Intel AMT received the DHCP suffix on the LAN interface (see AMT_SetupAndConfigurationService.DhcpDNSSuffix). Note that this is necessary even if a DNS suffix was set in BIOS. See the note below.

       c. If a DHCP domain name is configured, continue the Host-Based Setup and Configuration provisioning flow.

       d. If there is no DHCP domain name configured – return to step a. Repeat until success or timeout.

 Note:

If Intel AMT is enabled after OS has completed receiving an IP address from the DHCP server on the LAN interface (the usual case), Intel AMT will not have an IP address or domain name (DHCP option 15). Without a domain name, ACM provisioning will fail. Although an IP address is not strictly needed for provisioning, it is essential for functionality. The same is true for the WLAN interface. While not needed for provisioning, an IP address is essential for functionality. To solve this, a new DHCP transaction must be generated.
