Hi,

The linuxppc kernel uses the open firmware to access the ppc machine infos, I want to be able to program to the open firmware to. Although there is a lost of info inside the ppc kernel I still want to know the internals (definitions etc) of “open firmware”.

Has someone documentation available? On inet I only found the UI description :(

Thanks, initially I had no luck with this site (I had find it),
http://playground.sun.com/1275/home.html#OFDCoreDoc

The two links of the core documentation are dead :(, and there has to be a way to get the documentation without having to buy “the book”.

But here it is, via this page http://www.firmworks.com/www/ieee.htm
I got to ftp://playground.sun.com/pub/p1275/coredoc/ where the coredoc is downloadable (it is old, but better then nothing), no idea why there are no pointers to it..

If someone has any newer documentation pls let me know, the system I use is from 2004.

Grts,
Ingmar

openbios.org has a better-organized documentation collection.

The Open Firmware documents have not changed for a long time (which is=20=

probably a bad thing).

BTW, anyone know of where to get the CHRP specs in downloadable html or pdf or something format. Not the chrp OF bindings, but the real CHRP specs ?

I believe you've seen this before, but the link is still in the same place... http://penguinppc.org/otherhw/#chrp

As I recall, though, the CHRP specification mandates such obsolete features as an ADB controller, so claiming "CHRP compliance" may not be all that special these days. :)

I got pointers to this document, in case you do not have it already (it's old but at least something)..
