Re: [tboot-devel] Buying a machine that will actually work with TXT

[Ross P. <Ros...@ci...>]

We have several HP 6930p laptops with MV chipset (GM45/ICH9). The
systems do not seem to ship with the AC module pre-loaded in BIOS from
what I can tell. At least when I use tboot without an external SINIT
module, tboot fails to validate the contents of the ACM BIOS area. I
think Intel should be making the SINIT for this platforms available
soon.

Thanks
Ross

Hi Jon,

That is a good question. In fact I think Joe would be the right person
to answer this. We (HP) get the latest BIOS and SINIT AC modules from
Intel for our mobile platforms. I am not sure if the SINIT modules
available on the Tboot sourceforge website (for desktop chipsets) can
be used on the mobile platforms which has the bios integrated with
latest BIOS AC module (I think both the modules should match for tboot
to work). I am guessing that the SINIT modules for the mobile
platforms will also be soon uploaded onto the sourceforge website.

Thanks
Karthik
