ICH8 chipset among others

[Alan Jones]

Hi All,

I've got a laptop I'd love to get coreboot up and running on. I notice
that it's chipset isn't
in the supported list yet, but some of the predecessors are.

I've put an lspci at the bottom of this mail. Any info on how I could
help out adding support
and testing would be great.

Cheers,

Alan

Note that the chipset is 965 + ICH8. ICH8 is only the southbridge.

Problem with the 965 is that no developer has both documentation and
free time to work on adding the support.

Documentation is key for a new northbridge and Intel doesn't give it
out if we ask. :\

Ahhh - thanks - I was wondering how to figure out north vs southbridge :)

I guess this means nobody has docs they could share? I've not done such
low level coding, but I'm game to give it a swing if somebody is willing to do
code reviews and answer stupid questions :)

Cheers,

We always love people willing to develop Intel platforms, because lack of
support from Intel, if that is your goal.

Also have you checked out the Intel website to see what datasheets and docs
are available for the 965 + ICH8?

Ahh, but that is what is so great coreboot, there is nothing low level
(Assembly) about it. It uses a high level language (C) to communicate
directly with hardware, no messy layers, a win win situation :-)
