I've got me a macbook and I'm figuring out how to install OpenBSD on it (I'm going to see if I can do it without BootCamp, appearently it's possible: http://refit.sourceforge.net/myths/). One of my friends mentioned "too bad about the evil" to me and so I started digging into one of the evils: Trusted Computing. How do I find out if this mac has a TPM chip? Apple is never open about this fact.
This page <http://attivissimo.blogspot.com/2006/04/trusted-computing-chips-found-in-intel.html> reports that some macs have them and some don't. It also says that in linux you can check `ioreg` for mentions of TPM. What would the equivalent method in OpenBSD? Would the chip show up in dmesg? Here's one dmesg http://erdelynet.com/tech/openbsd/openbsd-on-intel-mac-mini/ and I don't see anything that looks like a TPM chip but I'm not sure what all the devices are. If I can't know for sure from software I plan on cracking the case and searching for one physically anyway. -Nick
