Description

Downgrade the TPM from version 2.0 to version 1.2 on Supported Dell Hardware.

TPM Version 2.0 is incompatible with BIOS systems and must be downgraded to version 1.2 if you would like to use the TPM on a non-UEFI system. This fixlet downgrades the TPM to version 1.2 on non-UEFI systems.

The fixlet will fail if ownership of the TPM has been taken on the system. For more information about this utility see: http://en.community.dell.com/techcenter/enterprise-client/w/wiki/11850.how-to-change-tpm-modes-1-2-2-0
