dig space.........."You Implied" to me means you "MADE IT UP"....... As to who does the work the TSS manufacturer or the TPM manufacturer....i DON'T KNOW! BUT ANY TPM CAN WORK WITH ANY TSS! That was my statement & i'm sticking with it! BUT IMO........... IBM does NOT have TWO TSS's & Atmel does NOT have TWO TPM's depending on What TSS they use! Doma.
