I installed Windows 10 yesterday with no problems whatsoever (with libgfxinit and tianocore).
What storage type? The Windows installer never detected my nvme drive.

Re: Coreboot on the X210

I'm trying to get libgfxinit working on a NV126A1M-N52 (2880x1920) There are some problems though: 1. Internal screen has only backlight on and works only when one plugs external display 2. resolution in the console (drm) is used from the external display. I was thinking that there is some kind of ...

Re: Coreboot on the X210

Hi, After playing with this for a week or so, a few questions arose: - Still unable to boot an existing Windows install with Tianocore. Some Googling suggests setting the SATA mode to IDE may help (the error is "INACCESSIBLE BOOT VOLUME" or "BOOT VOLUME NOT FOUND" or similar). Does this port have a...

Wow, you're a lifesaver, do you accept donations? (BTC preferably)
Thank you for you work.
I second this. I'll happily make a donation too. After all we paid good money for this machine, don't see why we shouldn't reward vladisslav2011 for making it actually usable.

You disabled it in the PCH-settings?
If so it still show ME State: Enabled, this is strange.
I think I did. Anyway you can always flash the rom and disable it yourself, I guess.

Re: X210 EC datasheet/better brightness control?

Since these changes for battery stuff are being made in the EC, would they affect Windows battery reporting? R These changes are being made in coreboot, so they would affect Windows only if it was running under coreboot, not the stock bios. But I guess this type of stuff could also be implemented o...

Re: X210 EC datasheet/better brightness control?

Hmm, I'm not sure - the value here is coming directly from the battery without being interpreted by the EC, so that would depend on the battery reporting broken units. Which certainly isn't impossible, but the numbers you're seeing with my patch are much closer to the numbers I see with a 9-cell ba...

Thanks, I'll merge these in!

Strange. Try booting with intel_iommu=off maybe? Also, I just realised that I killed the ME with me_cleaner in this release, that could be related to the issue.

Ok, the solution to the battery conundrum lies in the Linux kernel sources: in drivers/acpi/battery.c On Lenovo Thinkpad models from 2010 and 2011, the power unit switches between mWh and mAh depending on whether the system is running on battery or not. When mAh is the unit, most reported values are...
