Life hack #37: how to make a great touchpad

To manufacturers of Chromebooks,

Sorry guys, I have a chromebook myself, and its touchpad is appalling. I've 
also tried the chromebooks in stores and they aren't much better.

But have no fear, Alex is here, and has the perfect recipe on how to squash 
such hardware bugs early on. Following these steps, you are guaranteed to 
never make this mistake again:
1. Go to your favorite bidding site
2. Enter the following search terms: "HP Pavilion M6 1035dx"
3. Find a matching listing
4. Purchase full laptop
5. When you get it, observe its touchpad
6. Notice the big, easy to hit buttons
7. Notice the surface area
8. Notice the smoothness of the surface
9. Notice the ease of moving the pointer
10. Notice the tactile feedback from the buttons
11. Notice the evenness of the force needed to engage the button
12. Notice the fatigue of repeatedly pressing the buttons (hint:there is none)
13. Play with its touchpad
14. Play some more with its touchpad
15. Now play with the Unreleased(TM) Chromebook's touchpad
16. If it seems inferior, it probably is

You'll be making perfect touchpads now, won't you?

Alex

[RFC] New patch to review for coreboot: a61a8fe util/board_status: Use capture and not commit time

Dear coreboot folks,

just a heads-up that I sent the following patch set touch board status’
directory structure for review.

pcengines/apu status

Does anyone on this list know if there are plans
to upstream the work that SAGE did for the new
APU mainboard from PCEngines?

Re: Bug in your code

Can somebody give me a sanity check? I can't see the error with the macro.
I won't say too much here -- just take a look. I'm not convinced the
code is wrong.

thanks

Blog post by Scott D.: Small Integers: Big Penalty

Dear coreboot folks,

in the IRC channel #coreboot, Patrick linked to an interesting blog post
from Scott from 2012 with the title *Small Integers: Big Penalty* [1].

At least to me the results were unexpected.

Thanks,

Paul

S3 Resume on AMD Trinity APU

For those of you with Trinity CPUs, coreboot, and working S3 resume, is it 
necessary to run the VGA option ROM on S3 resume to get video back? Which 
output are you using (VGA, DP, etc) ?

Fans and BIOS

Hello.

I'm searching for any information about where (memory, IO port, etc.)
the status (on or off) of the fans of a laptop are stored. Anything is
very welcome! This is to improve the compatibility of i8kutils package
at Linux. The site of the development is
"https://launchpad.net/i8kutils".

Thanks in advance.

ASRock E350M1 start automatically after a electric cut

Hi,

My E350M1 start automatically after a electric cut. I tested this in
the hope but I get the same result:
http://review.coreboot.org/#/c/5397/

I do not have this problem with the manufacturer bios. Does watchdog
is used by default? Do you have an idea or solution?

Thanks, best regards

Thinkpad X61

Hi!

Does some have the X61 running with coreboot and can provide help to a
beginner (config, images, ...)?

I read the X60 wiki articles and there is a X61 mentioned as a
reference. But the actual chips seem to differ very much.

TIA

So, you want to try coreboot? Here are a few hints

Installing coreboot can be an either enthralling or appalling experience. If 
you're new to coreboot and want to give it a try, following a few simple steps 
can save you a ton of time and frustration.

Ask around first
================

Let the "coreboot people" know you want to try coreboot on board 'xyz'. You 
may find someone with the same board, who may be able to give you hints on 
flashing. This is especially useful on laptops, where a brick will most likely 
result in the need for disassembly to access the flash chip, and external 
flashing.

Prebuilt images
===============

If you're lucky enough to find someone with the same board as you, they may be 
able to provide a pre-built coreboot image. This eliminates issues where 
flashing is done correctly, but a mysterious bug prevents the system for 
booting.

Binary coreboot distributions
=============================

Sometimes people get together and create tested binaries binaries for a subset 
of boards. They can give you help on flashing, and making sure your board 
works as expected. This is by far the best way to try coreboot.

If you have a Lenovo X60, give the libreboot[1] guys a holler. That's libre-
boot, not lib-reboot.
