"Platforms containing a TPM require both a TCG Software Stack (TSS) and embedded security software. All models provide the TSS; embedded security software must be purchased separately for some models. For those models, an NTRU TSS is provided to support customer third-party purchase of embedded security software. We recommend third-party solutions such as Wave Embassy Trust Suite."
If the model uses a NTRU TSS then you will need to buy third party software such as ETS.......
Now why would HP be using NTRU's TSS on some models???
Find of the year! To find a recommendation of ETS in a description of HP Protect Tools is incredible!WOW Obviously HP sees a need of OUR software for interoperability...LOL
