I have added other 2 repos on my github. Again focus on coreboot and including specific roms for the x230 and the t430 models.

For the x230 my exigence was too get out of the skulls roms building something more personalized.

For the t430 it was a new challenge, and as I couldn't find on internet any specific or ready to go configuration, I hope it could help in future projects focus on automatizing the process of flashing custom bios.

All the details on my github

Coreboot on x230 - How to change the Skulls bootspash image

I assume that skulls is already installed on your x230 and you are happy with it :) however you would like to change the bootsplash image.. It seems to be simple... however it can be "tricky".. or at least it was for me..  That's because the "usable" image created by the skulls script is the "top" one only. the coreboot instructions to flash with a layout file with didn't work for me 0x00000000:0x007fffff ifdmegbe 0x00800000:0x00bfffff bios I get this error: Proceeding anyway because user forced us to. Found chipset "Intel QM77". Enabling flash write... Warning: SPI Configuration Lockdown activated. Enabling hardware sequencing due to multiple flash chips detected. OK. Found Programmer flash chip "Opaque flash chip" (12288 kB, Programmer-specific) mapped at physical address 0x0000000000000000. Error: Image size (4194304 B) doesn't match the flash chip's size (12582912 B)! So I thought it could be a good idea to flash fro...

Skulls scripts - how to make the seabios_free version bootsplash showing and adding secondary payloads

I was playing with the skulls scripts  for the seabios_free to rebuild the coreboot image for the thinkpad x230, considering that, as reported on their github, it: "includes the VGA BIOS SeaVGABIOS which is free software. While technically more interesting, visually this is currently not as beautiful: The bootspash image is not shown ." The solution that I have fund is not perfect as the supported resolution by libgfxinit is limited to 1024x768, so the image is shrunk, however it does show and it works fine for me. I have replied then on this thread /issues/59 What we have to change to fix it is not the .config file present in the /x230 folder but the free-defconfig-8053595370 file to set the correct resolution to the libgfxinit adding the following: CONFIG_LINEAR_FRAMEBUFFER_MAX_WIDTH=1024 CONFIG_LINEAR_FRAMEBUFFER_MAX_HEIGHT=768 Once done we still need to add the bootsplash image as per the seabios coreboot instructions  However I think that adding on the script someth...

Coreboot with Seabios and VGA on ThinkPad T400

I have a beautiful t400 running libreboot and still working amazing, however... I needed to boot windows 10 on it ;( I come across some guides on internet to recompile coreboot for this or similar models however the instructions didn't work if you aim to run windows on it.  Obviously re-flashing the stock bios is not a "reasonable" option for me.. and I couldn't find any alternative "ready to go".. so I decided to recompile coreboot and making it capable to boot windows 10 on my t400. From this personal small "project" I got the benefit to be able to boot any other linux distro and any bsd (I have tried freebsd only so far) without any complicated settings to add on the grub configuration. Also, it doesn't include any Intel ME (the same as libreboot) which is a backdoor (https://www.theregister.com/2017/11/20/intel_flags_firmware_flaws/) and I feel like that coreboot and seabios are immune to the recent grub security issues (not sure if they ca...
