I recently learned about Intel's P-MAPS research project which
provides an alternative way of using TPM+TXT to provide attestations
and sealing in the context of a standard OS. Here is a link to the
Intel Research blog post:

My log is attached, including the hang and the relaunch of tboot. This
is version 20090330 of tboot. Thanks very much -

I'm afraid these terms mean nothing to me. Azalia is something about
HD Audio? I don't know what that has to do with VT-d. Googling for
lsoc with VT-d or with Intel finds nothing relevant. And WA could

an
experimental SINIT with additional debugging outputs or error codes if
that would help. I'll also try reverting the BIOS version and see if
that makes a difference.
Thanks for all your help -

which works with SINIT but reveals nothing when there is a failure.
Neither is a great alternative.

query to see which SINITs are good and which are bad? Intel is going
to be in trouble if anyone actually starts to use this technology,
with their current lack of attention to these kinds of details!

I've finally found the STM certs in the supplemental information on the
TPM datasheet:
www.st.com/internet/mcu/product/252378.jsp
Infineon certs are available at
http://www.infineon.com/tpm
I didn't know about STM's having certs, thanks for the pointer. I don't
know of any other TPM
You know, you don't have to mess around with this LCP stuff to get tboot
working. I'd recommend ignoring this stuff when you're getting tboot
working for the first time. Don't define any NV space. tboot will work fine
without them. You'll see some error messages in the log, but they are
harmless.
tboot; I'm trying to get Jon McCune's flicker working, but that uses the
same technology.
Not very many laptops come with serial ports any more. But it has something
called AMT which can theoretically emulate a serial port over ethernet. I
