@libreleah sounds great! Good luck!

Last question: Do you have plans for supporting ThinkPad T60 with ATI GPU in os-boot project?

I made a Coreboot image with ATI support for it a long time ago with SeaBIOS as a payload. Clean GRUB2 payload didn't work (no image while booting) but SeaBIOS+GRUB2 chainload _should_ work. If you interested I can translate a guide for you :blobcat:

@Evv1L it's on the backburner. the issue is i can't legally distribute the vga rom required; however, it should be possible to automate the extraction of it

the issue with that particular GPU is that lenovobios modifies certain parameters of it at boot time, in ways that coreboot does not

in coreboot, you have to use a rom extracted from /sys/ pre-modified from when you booted with lenovobios

i could distribute roms, and tell you how to extract that vga rom, but i can't distribute the vga rom

@Evv1L regarding grub: you can set coreboot to boot in text mode, and then grub should Just Work

in my tests, booting in VESA mode never works on that board, when using the VGA ROM. you must boot grub in text mode
