Hello,

As a software developer, I am interested in learning more
about the Intel Trusted Execution Technology (TXT). I think it's a very
exciting technology. I've been following the developments in trusted
computing since the TCPA (and later TCG) specifications, Microsoft's
talk about NGSCB in Longhorn, Lagrande rumours etc. and it is very
interesting to now see it all realized in hardware.


I've read the relevant sections of the Intel System Programing
manual and the Q35 chipset spec as well as the preliminary spec on TXT.
I'm very interested in writing some experimental TXT code and from
reading product specifications it seems this would be possible using an
Intel
Core 2 Duo CPU as well as a DQ35MP or DQ35JO mainboard (featuring the
Q35 chipset and a TPM 1.2 chip). My understanding is that I will need
to have a chipset-specific, signed SINIT AC module loaded before I can
launch my own MLE. The preliminary specifications suggest that the
SINIT AC may either be loaded by the BIOS or later by system software.
So my question is, is a SINIT AC module loaded by the BIOS on the
mainboards mentioned or is it possible to obtain the SINIT AC somewhere
else?

I've seen numerous references to the manual "Intel Trusted
Execution Technology Measured Launched Environment Programming Guide"
in the documents mentioned, but I haven't been able to find it
anywhere. Is it possible to obtain a copy?


I'm also curious to know what usage models Intel envisions. It
seems you are about to launch a vPro initiative and that TXT will have
some role to play here. Does this mean that the TXT functions are not
currently available to the wider developer audience (
i.e. is it mostly intended for vPro-usage at this point)?

Thank you in advance!

is a link for Trusted Boot. Trusted Boot (tboot) is an open source, pre- kernel/VMM module that uses
Intel Trusted Execution Technology (Intel TXT) to perform a measured and
verified launch of an OS kernel/VMM.

Hi,

I have an hp dc7800 machine with intel Q35 express chipset, which I believe supports VT. I have been trying to perform a tboot. I have looked around on the net for the SINIT AC Module for this chipset and I can't find any. Does anyone know where I can download one? Is this supposed to be produced by intel or hp?

Asking internally on your behalf. Stay tuned.

Here's what I was told:

This system *does* support TXT. You candownload the SINIT AC module for it from https://sourceforge.net/project/showfiles.php?group_id=205557&package_id=255119.Choosethe Q35 & X38 Express download and then the Q35_SINIT_17.BIN file from within the tarfile.
