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.
Activate Embedded Security On Next Boot
Activate TPM On Next Boot
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.
