    Verified boot (V): Turns BtG verification on when set. Determines whether S-ACM verifies the BIOS IBB specified in the BPM.

    Measured boot (M): Turns BtG measurement on when set. Controls whether S-ACM will measure IBB segments and extend into PCR0 of the TPM/PTT.

    TXT Supported (T) [New]: Setting this bit indicates the platform/BIOS supports TXT.If set, BIOS should provide a setup option to enable/disable TXT via FIT type A record.If not set, the platform is incapable of TXT operation.

    Force Anchor Cove Boot (FACB): When set, causes an immediate unrecoverable shutdown if the S-ACM is unable to run for any reason. Typically this is set only if ENF=3. Turns BtG verification on when set. Determines whether S-ACM verifies the BIOS IBB specified in the BPM.
