I was having a lot of trouble enabling the TPM in my task sequence in SCCM for the 6570b. Using the biosconfigutility part of SP52095 I discovered that HP have for some inexplicable reason, changed the command to enable the TPM.

OLD:
Activate Embedded Security On Next Boot
Disable
*Enable

NEW
Activate TPM On Next Boot
Disable
*Enable

To be safe, I’d do a /getconfig and makesure that everything else is right. They’ve changed a few other “Embedded security” tags to be simply “TPM” instead.
