X220/X230 to flash or not to flash coreboot after FHD mod
Hi,
So after installing the FHD mod from Nitrocaster (but without the sense wire) , I am thinking in flashing coreboot into my X230 so I can install not whitelisted pci.. The problem here is since I don't have sense wire I had to force to use the displayPort fron the docking station as default screen, is there anyway you can set up that using coreboot or I will need to better remove the whitelist from my Lenovo bios and then reflash it back.?
Anybody with some ideas?
Thanks a lot in advance

You can use external monitor so that it would be the only display in your system. Just make sure you disconnect both cables from the adapter board before powering up.

Well sorry but actually I think that maybe I wasn't clear in my post... What I wanted to say is that in order to use your mod as default screen (exactly what I want ) and not having problems whenever I'm on battery only, I need to setup in the bios as default screen (currently in the Lenovo bios for making your card work I need to setup as docking station external monitor as default screen and it works without any troubles).. So since I want to get rid of the Lenovo whitelist in bios, I have two options :
1- Mod my Lenovo bios and remove the whitelist and reflash it again
2- Use coreboot
I would go to the option 2, but not sure if I can would be able to use your mod wirh it since I'm not sure, I would be able to setup your mod as default screen (remember that I cannot use the sense wire).... So the question is, if somebody who has coreboot in his / her Lenovo can boot directly in other external monitor as default?

Re: X220/X230 to flash or not to flash coreboot after FHD mod
I was thinking about installing coreboot too.
My FHD install is still in progress, i'm waiting for LCD-panel to arrive.
Not sure, but I suspect that only thing you need to change in coreboot is value of https://github.com/coreboot/coreboot/bl ... ree.cb#L10
to 3. [1]
[1] https://github.com/coreboot/coreboot/bl ... chip.h#L33

And in your case to remove https://github.com/coreboot/coreboot/bl ... tree.cb#L7

Well that look impressive, actually I thought that there was needed to change some value in some config not the code itself, but it looks ay least quite congruent, I ordered some small wires for the clip so whenever I would receive it Ibwoyld give a try to this ans let's see... Thanks very much for your advice

I'm not sure if this is necessary or not.

Well definitely I will have to try out, I hope at least that one of the screen will work though after the first flash, to don't need to do all the time with the ponoma thing Well now I will need just to wait to my shorter cables to be able to read the chip and once I have done correctly the backup of the bios I will try that...

It should be gpu_dp_b_hotplug, which is left side mini display port.

Well I am asking in the mailist from coreboot, and they mentioned that indeed this options are changing the sequence for switching on the power and backlight to the screens'; but still I have two problems to solve:
1- The ponoma clip + RPi are not able to read my bios, I think I had just a problem with the module spidev, but even if I repair i still not working...
2- Still don't know if the screen will work with coreboot...

Re: X220/X230 to flash or not to flash coreboot after FHD mod
Clip and raspberry pi. I didn't have much trouble with it.
I used the AC + wake on lan method of powering the EEPROM, I didn't power it with the raspberry pi 3.3v.

Re: X220/X230 to flash or not to flash coreboot after FHD mod
The one I tried, for many times and no luck, don't know if the problem is with the clip itself, the Rpi(type B), I have some problems with the kernel modules, I installed the last two Debian releases availables, and the module spi-bcm2708 is not present, just the spi-bcm2835, and when I "modprobed" it and the spidev, it's creating the devices /dev/spidev0.* but the flashrom application is not working somehow... I already don't know what to do...Quantumcross wrote:Clip and raspberry pi. I didn't have much trouble with it.

In the other hand, I asked in the coreboot mail list what about to power external screen, and I got the following response:
https://www.coreboot.org/pipermail/core ... 82956.html
So basically they told me not too have much hopes of making it work with coreboot, unless doing some reverse engineering or some ADA programming ...

Re: X220/X230 to flash or not to flash coreboot after FHD mod
I read through the thread and It sounds like to me that there might not be a problem if you use the original extracted VGA BIOS. I wish I could be a guinea pig here, I will be ordering an FHD kit with the next batch.

Re: X220/X230 to flash or not to flash coreboot after FHD mod
Reading what the one guy said in the mailing list: "I guess, the easiest option for your setup is to let SeaBIOS run the original Video BIOS with a modified VBT"
I looked into it a little bit and found that you can dump the VBT with the coreboot tool "intelvbttool"
There is one line that interests me...

Re: X220/X230 to flash or not to flash coreboot after FHD mod
Hello everyone, my first post on this forum
Few days ago I've received my x230, this is the first thinkpad laptop I own and so far i like it very much. I would like to do the FHD mod on it and I would also like to install coreboot or later maybe even Heads if it's not much more complex than creating a coreboot rom. So far I've managed to successfully read both flash chips using raspberry pi and a soic clip. I've extracted required blobs, compiled all necessary cross compilers and created my first coreboot rom. I'll try to flash coreboot this weekend, hopefully this will work.
With regards to using coreboot and future FHD mod what I understand, after reading this forum, is that if I will have the mod installed correctly with the sense cable it should work the same way as with the original UEFI firmware, the only problem I can have is if the sense wire is missing like in carcuevas case and than firmware needs to be forced to choose the correct video output device?
My second question is about linux kernel patch linked by nitrocaster, https://gist.github.com/nitrocaster/2bb ... d162a48c73 has any of you who use linux and have the FHD mod done it, does it really disable LVDS?

Re: X220/X230 to flash or not to flash coreboot after FHD mod
Yes, it does. I came up with that patch, thanks to the help of the i915 devs, and have been using it for over two years. The patch completely disables LVDS and has the driver detect DP-D as an eDP port. That way you have brightness control and no screen duplication. Ah, the joys of free software.nrg-fv wrote: My second question is about linux kernel patch linked by nitrocaster, https://gist.github.com/nitrocaster/2bb ... d162a48c73 has any of you who use linux and have the FHD mod done it, does it really disable LVDS?
Two things you have to keep in mind if you use it.
1. If you suspend or hibernate the laptop with the lid open it will immediately come up. This is annoying, but is easily fixed by disabling the lid as a wake up source. You have to do the following at every boot (put it in a startup script or something)
Code: Select all
echo LID > /proc/acpi/wakeup
2. the screen will stay blank when docked to an Ultrabase 3. Mini dock works fine, ultrabase kills the screen. Never investigated why, as I am happy with my mini dock.
Re: X220/X230 to flash or not to flash coreboot after FHD mod
Thank you for your reply harryK, it's good to hear that the patch is working as advertised and thank you also for helpful tips which I'm sure will find handy once I'll do the mod From your post I figure you use your laptop only when attached to a docking station that's why you don't need LVDS but I guess you haven't done FHD mod, have you?
BTW. Yesterday I've flashed coreboot into the 4MB chip and unlocked the 8MB using external flasher. All worked Than I flashed 8MB chip using internal flashing option from within the system with the rest of coreboot firmware which included neutered ME. All works fine so far, the only thing I had to do is to blacklist mei_me module as it wasn't happy that ME is missing I still have some problems with some drivers and ACPI as errors are showing in dmesg but I guess this is not the correct topic to discuss this.

Re: X220/X230 to flash or not to flash coreboot after FHD mod
I have the mod. Sorry if that wasn't clear. I use my laptop normally, and it works perfectly (video here https://www.youtube.com/watch?v=e4qizhnbui0). LVDS has to be disabled so that the operating system doesn't detect two screens (non-existent LVDS and DP-3/eDP). Windows, for instance, detects two screens and people have to configure them in mirroring mode if they want brightness control. Also, with two outputs powered the GPU consumes more energy.nrg-fv wrote:Thank you for your reply harryK, it's good to hear that the patch is working as advertised and thank you also for helpful tips which I'm sure will find handy once I'll do the mod From your post I figure you use your laptop only when attached to a docking station that's why you don't need LVDS but I guess you haven't done FHD mod, have you?
The only problem is with Ultrabase 3: with this mod the internal screen doesn't come up when docked. However everything works with the mini-dock.
Good luck with your mod
Re: X220/X230 to flash or not to flash coreboot after FHD mod
Thank you, luck will definitely be needed I've seen your video and correct me if I'm wrong but I'm guessing form a very fast boot time you also do have coreboot on your machine? As I've seen a splash screen with Lenovo I'm assuming coreboot was compiled with embedded vga bios or maybe you have a whole kernel as a payload? Was there anything you had to change within coreboot config because of FHD mod?

I have a T400 which does not have a display, it uses ONLY an external monitor.carcuevas wrote:So the question is, if somebody who has coreboot in his / her Lenovo can boot directly in other external monitor as default?
The boot process does NOT display. During startup, the first output to the screen is a few lines of scrolling text just before the login screen.
Option 1: Check your wiring is correct.it's creating the devices /dev/spidev0.* but the flashrom application is not working somehow... I already don't know what to do...
Option 2: Try disconnecting the 3.3v and Ground from the raspberry pi, and connect the ac adapter to power the eeprom.
Option 3: reduce electrical interference between the board and the external wires connecting the Pi to the chip.
It sounds like Raspberrian, the operating system, is set up correctly.

I tried the coreboot image for x230 from this link, and it works fine. I have a lot of ACPI errors on FreeBSD, but apparently everything seems to be working fine.
