it is not in the chipset
because that is the object of its measuments
to prevent us from exchanging chip sets
ok
leaves only the CPU and the Intel Engine
it wouldn't be the CPU because that is externally accessible
what is not externally accessible
that is without a key known only to the plat form owner
is the Intel Engine
furthermore there is a matter of hierarchy
in which the Intel Engine decides
on whether the CPU is allowed to run
we know where the hash is
"in the TPM in a protected non-volatile location that can only be
modified by the platform owner"
but where is the code itself and that database of known-good cumulative
PCR values
that allow us to start
wherever it is they are in
is any of it hard coded any way
or is the owner preparing to change his moods every other day
on whether or not we are allowed to boot a particular system configuration
I think we are entitled to a fixed set of its launching specifications
at the time that we purchase this - eh - plat form
and not just a reliable set
based on trust
alone
