Field

Description

Reserved

8 bytes

StructuredVersion

The version of this structure. 16 MSB correspond to the major version, 16 LSB correspond to the minor version. For this version, the structure version is 1.0.

AmtSupported

This value is true for an Intel AMT capable machine, and false for a machine with no Intel AMT capabilities. If this value is false, the rest of the structure values are ‘don’t care’.

0 – NOT Supported

1 - Supported

2 and higher – N/A (ignore)

AmtEnabled

This value is true for an Intel AMT capable machine, where Intel AMT is in a working state.

0 – Disabled

1 - Enabled

2 and higher – N/A (ignore)

IDEREnabled

This value will be true if Storage Redirection is enabled.

0 – Disabled

1 - Enabled

2 and higher – N/A (ignore)

 

Note: Beginning in version 11.0, Storage Redirection uses the USB-R protocol rather than the IDE-R protocol. The value name has not been changed so as to preserve backwards compatibility.

SOLEnabled

This value will be true if Serial Over LAN capability is enabled.

0 – Disabled

1 - Enabled

2 and higher – N/A (ignore)

NetworkEnabled

This value will be true if the network interface of the Intel AMT device is enabled.

0 – Disabled

1 - Enabled

2 and higher – N/A (ignore)
