now I guess all we've got to do is hack the efi to give the image a cryptographically identical (read supercomputer style impossible) reading for the tpm module to say 'green lights means go kids, enjoy your apple hardware'.
now it's up to l33t hax0rs to do just that
arrrgh I want half me bounty for providing the map

this means in short that the efi has been signed by apple and the only one that they will allow (currently) to boot their hardware.
perhaps they need to get their legal team working on a disclaimer of liability for unsupported platforms and loosen their shorts a bit? I can't foresee anyone actually suing apple because windows crashes! that would be akin to suing ford because your chrysler spontaneously combusted.
easy steve et all, we like the work, lets keep it going:D

Exercise your commercial rights and ask for a complete refund for this crippleware with undocumented features like TPM and EFI crc checking hint hint (llamas for not listening) while you can.
I've worked with engineers at IBM for boot sequence problems while employed by them, and understand a fair bit about what happens during a boot sequence. This doesn't make me a name dropping hack, it means that I'm actually approaching this problem with some low level understanding of the hardware as it lights up.
As I've stated earlier, I believe that the TPM unit checks the EFI to ensure it's Apple standard EFI (/. ers would all understand this) and then opens the system devices up based on a correct check. It seems to me the failure and 'non-bootable' status only comes after actually altering the EFI. I guess we're all/. ing and not connect the . ing.
rent a clue day coming soon to a planet near you!
Could it be that the TPM module is being used to verify the state of the EFI?
It would make sense to me, that one of the most fundamental aspects of a Trusted Platform Module would be to ensure that the platform is booting in a state you can trust, and not booting on some hacked EFI pointing to (and enabling) devices that the user has no idea are installed. As this is Apple's (or any major vendor to my knowledge) first foray into the TPM arena, perhaps this is part of that whole security featureset that you paid for but can't work with, I'm in the same boat, and would like to feel free to try Darwin in other incarnations as well as use the equipment for Windows and prove to my friends outright why Apple is such the superior gear.
Is there any way we can map the calls made on the system bus during the complete post? Do we have ANY information on how TPM is being used here?
There's a glaring hole in the documentation imho a long way from the 1984 ad...http://www.uriah.com/apple-qt/1984.html but there always seems to be someone's visage up on that screen no matter how you slice it.

I'm sure that ole Bill and Steve would like to see it boot normally, AT LEAST ONCE since its been coded.
