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.

I have a Macbook 2,1 that I run OpenBSD exclusively on. No Boot camp

or anything special. Just OpenBSD as it is.

There are a few things you need to know before you install. You will

need acpi and you will need an external USB-keyboard during

installization.

I use AMD64 and GENERIC.MP.
I did some googling about TPM in macbook and newer Apple hardware and

it seems like there isn't one.

Both these links say newer Apple hardware does not contain it, they

only mention Mac Pro and Macbook Pro's though.
There are still a few problems with the macbook, I'm trying to write a

driver for Apple system Management Controller, it's not going that

good but I should have it working soon. There is a few other problems

like bluetooth, iSight camera, IR. Sound is working and trackpad is

working.

ooh, first: thanks for your quick response.
What *is* BootCamp? I know it's mostly just repartitioning software

but the readme that comes with it seems to imply that it install

certain special drivers to let you use the mac keyboard under windows

(i.e. Mac-Click is mapped to right click, and so on).
Why do you need acpi? I did read that and I did make myself an

acpi-enabled kernel that I can boot from if I choose (though really I

could just do drop into config from boot>, right?) but the default is

to boot the normal i386/bsd.rd and when I let it do that it boots fine

and gets to the install prompt. What's the problem?
I did indeed run into the problem of the keyboard not working during
Is there an advantage to AMD64 over i386? My default was to grab i386

This just references the link I gave.
Still, TPM needs software to run it. It would be a very strange move

for Apple to somehow hide the TPM from anything besides OS X. I'm
I only have a Macbook. Maybe they big-brother anyone who doesn't shell
Oh sweet, that's really nice.

Related but off topic question: How do I get right-clicking working?

Do I have to play with X keymaps? I've poked at this from playing on

zaurus, but I don't really understand it. Links please?

I'm guessing there's nothing like Appletouch

<http://www.popies.net/atp/> in OpenBSD right?
The SMC controls low-level power functions. Does it do that on its

own? (i.e. if I sleep while under OpenBSD does the light still

Boot camp is both a tool to handle dual boot of operating systems but
Ok then it has started to get better because in the beginning I

couldn't even get to the install prompt because it hang on some usb

controller. ACPI is needed to get some of the drivers to work
Well the new Intel Core 2 Duo are Intels version of AMD64 and there

fore the closest thing you should use. You could use i386 also and
I haven't got the right click to work, I do not know if it's possible

to do. It is one of the annoying stuff at the moment and I use an

external USB mouse. I also have problems with the swedish keyboard

layout because {,[ ,] ,} are existing and this is annoying when you

code =) That Appletouch driver you linked to looked old and it's only

for Powerbooks. I know the FreeBSD people has done some work on it so
Well sleep and such does not work very well in OpenBSD. The screens

turns black after a while but the backlight seems to still be on. This

is controlled by ASMC. The hardware still work in most cases but there

is no way for us to controll it at the moment as the driver could

enable us to.
