Dear coreboot,
We are interested in coreboot for the Intel Haswell processors.
coreboot appears to be used in the Acer C720 and HP Chromebooks
that use Haswell processors. I see no reference to this processor,

Yes start spinning for a moment and then stops (Obviously until seabios

Could you please bisect

I expect that the noise comes from power supply circuitry.

Among the things that first impressed me with coreboot was the boot time
demonstrated in https://www.youtube.com/watch?v=HKdLhbmjrDI
If anyone is interested, I could successfully replicate a similar boot time
on a debian wheezy, with a modern coreboot chain loading to grub2, on a
x60
This is great. We've gotten an acer c720 down to 1.7 seconds from power
button to chromeos login screen. I've always wanted to get it done in under
a second. I hope you can get there!

Hello
I'm currently trying to make the tp_smapi modules work
thinkpad_ec and hdaps were easy to patch (basically adding a special case
and HDAPS_DMI_MATCH_INVERT_CUSTOM to match only on DMI_PRODUCT_VERSION
since DMI_BOARD_VENDOR was not set at all with the coreboot I was using)
However,

An extension to this project would be to teach linux/systemd to read our

As always, when doing a new board, get a system that is known to work with
coreboot and has your chipset in it. You should get several (never just
one!) of the haswell chromebooks, build coreboot, make sure you can make it
all work, then try the port to your board.

Double check: the chassis fan turns off. Sometimes, that's correct behavior
until things get warm, and the fan should turn on.
So you're sure the turning off is the wrong thing to do? In some cases it's
desirable for a chassis fan to spin up, then turn off, then turn on again
as needed, all under
Hello!
What he said. Ron you are very right here. The rules were one to use,
and one to ,ah, hack.
Now I freely admit all I know about bringing Coreboot to the
Chromebooks is what is discussed here. But I did indeed study and
follow the earlier efforts, and doing these ports can be considered
In the last few years I've argued for even 3! One to remain untouched, one
to hack, and one as the backup when you burn the hack one up :-)

While a couple of the Haswell-based ChromeBooks have been added to upstream
coreboot, but have not heard of anyone with them actually running yet. I know
John Lewis had tried to get the HP ChromeBook 14 (falco) going but was not
successful (though he does have the Chromium/falco branch
My advice if you're working with those chromebooks is to start with the
chromeos tree, not the upstream.

Dear coreboot,
We have done some more research on the differences between the
supported Haswell processors and PCH parts and what we have
used in our design.
We have designed a board with the E3-1268Lv3 device with the
82C226 PCH part. It appears that all Haswell devices that
have been ported
